  • Climate battle line: Community mobilisation or Canberra lobby?

    Climate battle line: Community mobilisation or Canberra lobby?

    by David Spratt

    Rally against carbon pricing, Canberra, 23 March 2011

    How should climate activist and climate campaigning organisations respond to the new Abbott government, and its goal of knocking out most of Australia’s climate programmes and trashing environmental regulation in the service of the fossil fuel and mining industries?

    • Should the methods utilised for the Labor and Labor–Greens coalition governments, of applying pressure and trying to negotiate better outcomes, be used?
    • Or should we set out to deliberately get the Abbott government out of office?

    The Abbott Liberal–National Party government celebrated its victory by abolishing Australia’s Climate Commission, the first baby steps in a culture war on climate programmes, the renewable energy industry and environmental regulation and protection.

    The Abbott government’s goal is to to facilitate the rapid expansion of the fossil fuel sector, including a gem from the new energy minister that he will ensure that “every molecule of gas that can come out of the ground does so”, by:

    • removing regulatory and tax imposts on the fossil fuel industry;
    • moving to diminish the effectiveness of the environment, climate action and anti-fossil-fuel-industry movements; and
    • inhibiting the growth of the renewable energy sector.

    This is a monumental climate battle, a broad social polarisation between two conflicting sets of values, principally on the relationship between science and ideology, the role of government, the relationship between humans and nature, and the future of the fossil fuel industry and of society’s technological path.

    The Abbott government’s climate policy may be described as Deny–Delay–Deregulate, and is founded on:

    • conservatism and the preservation of the status quo against change: a desire to hold back the sea in the service of the fossil fuel industry, even while recognising that a huge economic–technological tide of change is closing in;
    • a commitment to neo-liberal, deregulatory economic policy: defence of free-market capitalism against higher levels of state intervention and regulation;
    • an instrumental view of nature as a resource for exploitation;
    • championing the interests of the fossil fuel industries  economy;
    • an anti-scientific stance, which extinguishes the distance between science and ideology and drives a culture war with a religious component against secular science and environmentalism; and
    • the ethos of politics as warfare, the virtues of confrontation and political extremism and the dumbing-down of politics.

    In opposition, Abbott’s tactics in propelling the climate war have included:

    • formal acceptance of climate change as real, but a downplaying of the human role as making only “a contribution”, persistent denial of any link between climate change and impacts including more extreme events, all accompanied by a chorus of denialist rhetoric from his caucus;
    • dumbing-down and politicising climate science, and the exploitation of scientific uncertainty;
    • tarring good climate policies with the brush of Labor’s political incompetence;
    • national chauvinism (along the lines “we will not act to disadvantage Australia while others… “);
    • utilising the politics of resentment to rally Howard’s battlers, the fishers, the shooters and the politically marginalised against the professional class and “inner-city elites”, such as climate scientists, policy-makers, The Greens, environmentalists, rich life-stylers;
    • promoting fear of economic loss, describing the effect of climate action, in Abbott’s words, as “to put at risk our manufacturing industry, to penalise struggling families, to make a tough situation worse for millions of households right around Australia”;
    • ruthlessly exploited the myth of cost of living pressures (as GDP per capita grew strongly), in particular that myth that renewable energy was the main culprit for higher electricity prices.

    1. A titanic struggle

    Before too long, Prime Minister Abbott will have Barnaby Joyce beside him as deputy prime minister and Nationals leader. At heart, both are denialists along with a significant portion of the caucus. Maurice Newman, the former ABC and the ASX chairman who will be the chair of Abbott’s Business Advisory Council, propounds “the myth of anthropological climate change”.

    Abbott’s record includes “the science isn’t settled”, it’s “highly contentious” and “not yet proven”, “it’s cooling”, “it hasn’t warmed since 1998”,  “there’s no correlation between CO2 and temperature”, and he is “hugely unconvinced by the so-called settled science”. Despite what he says, this is what he thinks and it will inform how he will act.

    The Abbott government will not be persuaded by reason and is not interested in compromise because this is a battle to be won, and compromise and negotiation are signs of weakness. For this government, fighting enemies is more important than reality-based policy-making. This is about the politics of resentment, fear and revenge, about winning, and about debilitating the enemy. Culture wars are not primarily about policy detail, but about building legitimacy, isolating the enemy and establishing dominance.  

    2. One big decision

    So what is the strategic response?  In the last term of the Howard government, trade unionism faced similar circumstances with the WorkChoices legislation and made a very clear decision not to give priority to working in Canberra’s halls of power lobbying and prying incremental changes from the government, but to devote all the resources they could muster to bringing down the government. Your Rights at Work was a well-resourced, strategic, unified and persistent campaign encompassing a strong public affairs component, membership mobilisation, and an electoral campaign over 20 marginal seats, each with a full-time organiser and local cooperation between the ACTU affiliates to facilitate systematic community outreach.

    The climate movement, both professional and community-based, faces a similar decision. Is the main strategy to work with the Abbott government, to cajole, negotiate and compromise to improve outcomes, or is the principal task to help it them from power?

    The former Climate Commissioners and the CEFC Board have both shown backbone in eschewing acquiescence, and taking on the government. The reality is that as long as Abbott stays in power, the Australian Government will do next to nothing on climate.

    Some of the big climate and environment organisations are structured for Canberra work, and ill-equipped for sustained, unified, effective community organising, so the instinct will be to continue as before. But this is a serious misreading of Abbott’s modus operandi, and spending large amounts of time trying to incrementally change really bad policy is a misallocation of resources, with a large opportunity cost. This would affirm Naomi Klein’s view that such groups face a systemic crisis.

    3. Non-cooperation: Delegitimise their claim to action

    Tim Flannery terms the next period a “gigantic struggle”. One of our purposes must be to de-legitimise the government’s claim that they are taking effective action against climate change through their Direct Action Plan, by people understanding its manifest inadequacy. It is no certainty that the government’s plans will have an easy or successful passage through the Senate, even after 1 July 2014. All sorts of odd outcomes are possible.

    Much of the climate movement opposed Rudd’s CPRS in 2009 because it was so inadequate, so it would be consistent to oppose Tony Abbott’s scheme also. The failure of the Direct Action legislation would allow an even clearer message that Tony Abbott has no real climate plan.

    If the climate movement works to incrementally improve Direct Action, it will provide the government with a fig-leaf of legitimacy which they will ruthlessly exploit. On the other hand, counterposing a real direct action plan to replace dirty coal power with renewables, and keep CSG and new coal in the ground, would build on existing campaigning and provide many paths to action for the community. It would demonstrate the clear choice between the dirty fossil fuel industry and increasing climate harm on the one hand, and the clean economy and future climate safety on the other.

    The possibility of sacrificing some existing policies to better defend others is a mis-reading of the politics. Every piece of legislation Abbott repeals is his victory. Why make it easy?

    Should we also make this about the opposing climate action views of Tony Abbott and Malcom Turnbull? Should Turnbull’s electorate be hit hard from now till June next year, challenging him to be morally courageous and not to backflip on climate legislation he supports? Tony Abbott made his daughters a political issue, maybe we can too, for example by talking about what sort of hotter world his daughters children will grow up in. Agriculture minister Barnaby Joyce on the fate of the Murray-Darling in a hotter world may be illuminating.

    4. Impacts first: Delegitimise their anti-science stance

    The Abbott government now wants to take boat arrivals and the efficacy of their refugee policy out of the public gaze. The same will be true of climate: their campaign in opposition was principally about Julia Gillard’s legitimacy, and less about the reality of climate change, and they have been neither willing nor capable of dealing with the substance of the climate impact issues.

    The past period where the Labor government (and NGOs to some extent in the “Say Yes” campaign, for example) tried to sell a climate policy without making the story about climate impacts was wrong, wrong, wrong. Brightsiding is a bad strategy. Trying to sell an answer without providing sufficient reason to act doesn’t work. Too many times in the past the climate movement has been reticent to connect the dots between extreme weather and climate change.

    The new Climate Council is but one small step in keeping climate science stories and impacts as public as possible. We can demonstrate the Abbott government’s ignorance and incompetence by hammering them over climate impacts on health, climate extremes, bush fires, food, water, inland Australia and the fate of farmers in and outside parliament every day, every which way. The attempts to silence and de-fund climate science research will likely backfire: on campuses, students can fire up in support of their teachers and against the politicisation of the academy.

    5. People, not Nemo

    A fundamental review of climate communication strategies is urgent. Climate story-telling should be about people, not Nemo. It should be about human values and morality, not economic and business rewards. Framing climate as an environment issue is counter-productive and plays to Abbott’s strength. So does making it a story just about the future, rather than also about now.

    Our story should be principally about people in Australia, not distant places. Our story should be about now: about connecting the dots between extreme events and global warming; about bush fires and extreme heat and suffering communities; a story about how family and friends will live and die in a hotter and more extreme world; a story about how a hotter climate and a retreating coastline will affect where we live and work; a story about health and well-being; about increasing food and water insecurity; and the more difficult life that children and grandchildren will face. This makes climate a values issue, the choice between increasing climate harm and climate safety, between warming caused by dirty fossil fuels and the solution of building a clean economy. [For more discussion see here and here.]

    The stories we tell vary with the audience: whether it be the impact of storm surges and rising sea levels on coastal communities and surf clubs; what more extreme fires means for first-responder workers, or more extreme heat days mean for the health sector; what drying of southern Australia means for farming communities; or how climate impacts will make the overseas aid policy paradigm obsolete.

    Society’s pace of change is creating new fears and insecurities as people struggle to keep up and worry about being left behind. And they fear about the future in which their children will live. Hyper-consumption is driven by insecurity — fear of being left behind, of being “unfashionable” in the broad meaning of the term — and self-entitlement. Sociologist Zygmunt Bauman says that: “Human vulnerability and uncertainty is the foundation of all political power.” Abbott understand the politics of fear, but do we?  Can we construct a  narrative that recognises fear and provide clear path to climate safety, rather than increasing personal and planetary insecurity? How can Howard’s battlers become safe climate champions?

    Doctors and scientists are credible public figures on climate. NGO talking heads fit the stereotype of middle-class, inner-city, professional, green elites making an easy living off climate alarmism. What will bring greater legitimacy to our side? Firefighters, nurses and first-responders of all kinds, surf-life savers, worried grandparents, tradies unable to work due to extreme heat, new parents, farmers forced off the land, retired military, John Hewson and Malcolm Fraser, Ian Dunlop, Cathy McGowan and Ita Buttrose.   

    6. Mobilisation

    The largest, most motivated and effective climate action mobilisation in Australia today focuses on coal and coal seam gas (CSG). Overwhelmingly,  the resources are devoted to the communities, not Canberra lobbying.

    The election campaigns in the seat of Melbourne and Indi championed the power of community organising. Resources such as NationBuilder can be tuned to issue campaigning as easily as candidate electioneering. Your Rights at Work provides valuable insights.

    Walk Against Warming 2006

    In the latter years of the Howard government, and during the first Rudd government, there were powerful expressions of community concern through events such as Walk Against Warming. Sectors including aid organisations, churches, unions, schools and students and grassroots climate groups all participated in a show of solidarity and concern. On the surface, many of those sectors appear to be much quieter now.

    If the strategic choice is to focus on bringing down the government, rather than cooperating in incrementally improving bad policies, then community and sectoral organisation and mobilisation is the key.

    At the scale now required in support of climate action, this has not been previously attempted in Australia.  It will require a lot of working out, cooperation in planning and execution, sustained unity in action, and a lot of resources. It will need a degree of trust, of sharing, and promoting the interests of the whole rather than the imperatives of the part. It will require that the lessons of the Say Yes review be absorbed, not palmed to one side.  It will require all sorts of things that many people say are “not possible” given the structures, relationships, branding imperatives and skill sets of the organisations and networks that should be involved, large and small. It will require a small revolution in how many parts of the climate movement work.

    If that really is “not possible”, then success in the battle is a lot less likely.

    7. “Holding the line” is not enough

    It is not enough just to defend what Abbott wants to destroy.  Climate change is already dangerous, time is very quickly running out if we are to avoid catastrophe. A safe climate is the only reasonable goal, and what it requires must be central to our narrative and actions. It requires, in the first instance, ideas leadership.

    International Energy Agency Chief Economist Fatih Birol calls the 2°C goal “a nice Utopia”, and the prevailing climate policy-making framework now poses a choice between a “dangerous but liveable” 2ºC of warming and the “catastrophe” of 4ºC or more.

    The aims of international climate negotiations and of the global climate action movement are to prevent dangerous climate change. But what do we do if global warming is already dangerous, and that 2°C boundary is itself a disaster?  This is now the case.

    Researchers Kevin Anderson and Alice Bows show that  if global emissions don’t peak till 2020, then the 2°C carbon budget for the developed world is… zero (4).  Even the 2ºC target requires actions that are completely outside the current climate policy-making framework, and therefore considered impossible.

    The UK’s Tyndall Centre says that:

    Today, in 2013, we face an unavoidably radical future. We either continue with rising emissions and reap the radical repercussions of severe climate change, or we acknowledge that we have a choice and pursue radical emission reductions: No longer is there a non-radical option. Moreover, low-carbon supply technologies cannot deliver the necessary rate of emission reductions – they need to be complemented with rapid, deep and early reductions in energy consumption.

    If we don’t establish public ideas leadership around these understandings now, what hope go we have ?

    Dear friend,

    On Friday the Intergovernmental Panel on Climate Change (the IPCC) released it’s 5th Assessment Report on Climate Change. This report is the most authoritative and comprehensive assessment of scientific knowledge on climate change, prepared by over 800 of the world’s leading experts. Its findings are clear – climate change is real, caused by human activity and needs to be urgently addressed.

    Since we’re quite fond of science and numbers at 350.org — after all, we’re named after the safe level of carbon dioxide in the atmosphere — we wanted to share a few of the key numbers from the new climate report:

    • 95%: that’s the level of certainty that scientists have that humans are causing the world to heat up. To put that into context, that’s the same level of certainty scientists have that cigarettes cause cancer. That’s what scientists call “unequivocal”. The debate on the basics of climate science is over.

    • 1 Trillion: the global “carbon budget” in tonnes. That’s the amount of CO2 we can release into the atmosphere while keeping global warming under 2 degrees Celsius — what many scientists have identified as a red line for our planet. We’ve already burned through about half of that carbon budget.  Translation: we need action. ASAP.

    • 1,2,3: the ranking of the last three decades in the “warmest decades in recorded history.” In other words: the planet is heating up, and we’re breaking new climate records every day.

    But there are a few numbers you should know about climate change that aren’t in the latest report — numbers that give us reason for hope:

    • 100%: that’s the expected growth in global installed solar power over the next two and a half years! That’s a doubling of global solar capacity in a mere 30 months. The renewable energy revolution has begun.

    • 20,000: that’s the number of events, protests, and rallies we’ve organized at 350.org globally. We’ll be adding to that with Summer Heat fast approaching. The movement is everywhere, and it’s active.

    • 100,000: that’s the number of new activists to have joined 350’s global network in the last few months. We’re growing — and fast.

    Unfortunately however, our new Government has stuck its head in the sand. As one of its first moves, Tony Abbott’s Coalition abolished the Climate Commission – Australia’s own version of the IPCC. The Climate Commission provided essential information to the Australian public on climate change, taking the politics out of climate science. And last week, the Government announced plans to introduce legislation that would ban boycotts on products for environmental reasons – preventing consumers from getting the information they need to make informed choices.

    But when the going gets tough, the tough get going. Just days after the Climate Commission was abolished, a new Climate Council was established, and it has been flooded with support from the community. Since Tuesday, thanks to small donations from over 20,000 individuals, almost $1 million has been raised. If you haven’t already chipped in, you can do so here. This is the power of community. And when it comes to the Coalition’s proposed anti-boycott amendments, we’ll stand up again to protect our consumer rights.

    The IPCC report lays out the challenge we’re facing. It’s now up to us to do what’s needed to meet that challenge. We can do it, but only if we keep up the fight. Check out our recently updated website: 350.org.au to see how you can join us.

    Keep up your courageous work!

  • How America Will Age Over the Next 30 Years

    How America Will Age Over the Next 30 Years

    By Morgan Housel | More Articles
    September 28, 2013 | Comments (2)

    Earlier this week, I wrote about the prospects of a new baby boom.

    The data behind the forecast is persuasive, in my view. Very few people saw the baby boom of the 1950s coming. Few will see the next demographic shift coming.

    But what if the baby boom forecast is wrong? That’s entirely possible.

    The current forecast among demographers is that America’s population will age for the next many decades. Our total population will still rise — and importantly, our working-age population will keep marching higher, too — but the average age of America’s total population is projected to rise over the years.

    Let’s look at the numbers.

    Ignoring immigration, population growth is a function of two forces:

    • A birth rate of more than two children per female
    • A declining mortality rate (rising life expectancy)

    For most of modern U.S. history, population growth was propelled by the former. From 1980 to 2012, fully 70% of U.S. population growth came from those under the age of 50.

    But things changed. The birth rate fell, and life expectancy is rising. If the baby boom story is wrong, and that trend continues, as the Census Bureau currently projects, population growth in the coming decades will be driven by growing numbers of older Americans.

    Here’s a simple way to show the shift, using the Census Bureau’s population forecast:

    Period Total Population Growth Growth, Age 60 & Under Growth, Age 60+ Share of Total Population Growth, Age 60+
    1980-2012 86 million 62 million 24 million 27%
    2012-2040 80 million 39 million 41 million 51%

    Breaking it down further:

    Period Population Growth,
    Age 20-50
    Population Growth,
    Age 70+
    1980-2012 31 million 12 million
    2012-2040 20 million 33 million

    This is tremendously simplified, but if you buy these forecasts, one takeaway might be this:

    • During the last three decades, the most growth was found in industries catering to young households — consumer goods, construction, education, and entertainment.
    • During the next three decades, most of the growth might be in industries catering to older groups — health care, retirement services, planning, and leisure.

    Observed changes in average surface temperature 1901-2012

    Summary for Policymakers of the Working Group I contribution to the Fifth Assessment Report

    A note from the Climate News Network editors: we have prepared this very abbreviated version of the first instalment of the IPCC’s Fifth Assessment Report (AR5) to serve as an objective guide to some of the headline issues it covers. It is in no sense an evaluation of what the Summary says: the wording is that of the IPCC authors themselves, except for a few cases where we have added headings. The AR5 uses a different basis as input to models from that used in its 2007 predecessor, AR4: instead of emissions scenarios, it speaks of RCPs, representative concentration pathways. So it is not possible everywhere to make a direct comparison between AR4 and AR5, though the text does so in some cases, and at the end we provide a very short list of the two reports’ conclusions on several key issues. The language of science can be complex. What follows is the IPCC scientists’ language. In the following days and weeks we will be reporting in more detail on some of their findings.

    In this Summary for Policymakers, the following summary terms are used to describe the available evidence: limited, medium, or robust; and for the degree of agreement: low, medium, or high. A level of confidence is expressed using five qualifiers: very low, low, medium, high, and very high, and typeset in italics, e.g., medium confidence. For a given evidence and agreement statement, different confidence levels can be assigned, but increasing levels of evidence and degrees of agreement are correlated with increasing confidence. In this Summary the following terms have been used to indicate the assessed likelihood of an outcome or a result: virtually certain 99–100% probability, very likely 90–100%, likely 66–100%, about as likely as not 33–66%, unlikely 0–33%, very unlikely 0–10%, exceptionally unlikely 0–1%. Additional terms (extremely likely: 95–100%, more likely than not >50–100%, and extremely unlikely 0–5%) may also be used when appropriate.

    Observed Changes in the Climate System

    Observed globally averaged combined land and
    ocean surface temperature anomaly 1850-2012

    Atmosphere

    Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, sea level has risen, and the concentrations of greenhouse gases have increased

    Each of the last three decades has been successively warmer at the Earth’s surface than any preceding decade since 1850.

    For the longest period when calculation of regional trends is sufficiently complete (1901–2012), almost the entire globe has experienced surface warming.

    In addition to robust multi-decadal warming, global mean surface temperature exhibits substantial decadal and interannual variability. Due to natural variability, trends based on short records are very sensitive to the beginning and end dates and do not in general reflect long-term climate trends.

    As one example, the rate of warming over the past 15 years, which begins with a strong El Niño, is smaller than the rate calculated since 1951.

    Changes in many extreme weather and climate events have been observed since about 1950. It is very likely that the number of cold days and nights has decreased and the number of warm days and nights has increased on the global scale.

    Ocean

    Ocean warming dominates the increase in energy stored in the climate system, accounting for more than 90% of the energy accumulated between 1971 and 2010 (high confidence ). It is virtually certain that the upper ocean (0−700 m) warmed from 1971 to 2010, and it likely warmed between the 1870s and 1971.

    On a global scale, the ocean warming is largest near the surface, and the upper 75 m warmed by 0.11 [0.09 to 0.13] °C per decade over the period 1971–2010. Since AR4, instrumental biases in upper-ocean temperature records have been identified and reduced, enhancing confidence in the assessment of change.

    It is likely that the ocean warmed between 700 and 2000 m from 1957 to 2009. Sufficient observations are available for the period 1992 to 2005 for a global assessment of temperature change below 2000 m. There were likely no significant observed temperature trends between 2000 and 3000 m for this period. It is likely that the ocean warmed from 3000 m to the bottom for this period, with the largest warming observed in the Southern Ocean.

    More than 60% of the net energy increase in the climate system is stored in the upper ocean (0–700 m) during the relatively well-sampled 40-year period from 1971 to 2010, and about 30% is stored in the ocean below 700 m. The increase in upper ocean heat content during this time period estimated from a linear trend is likely.

    Cryosphere

    Over the last two decades, the Greenland and Antarctic ice sheets have been losing mass, glaciers have continued to shrink almost worldwide, and Arctic sea ice and Northern Hemisphere spring snow cover have continued to decrease in extent (high confidence).

    The average rate of ice loss from the Greenland ice sheet has very likely substantially increased … over the period 1992–2001. The average rate of ice loss from the Antarctic ice sheet has likely increased … over the period 1992–2001. There is very high confidence that these losses are mainly from the northern Antarctic Peninsula and the Amundsen Sea sector of West Antarctica.

    There is high confidence that permafrost temperatures have increased in most regions since the early 1980s. Observed warming was up to 3°C in parts of Northern Alaska (early 1980s to mid-2000s) and up to 2°C in parts of the Russian European North (1971–2010). In the latter region, a considerable reduction in permafrost thickness and areal extent has been observed over the period 1975–2005 (medium confidence).

    Multiple lines of evidence support very substantial Arctic warming since the mid-20th century.

    Sea Level

    The rate of sea level rise since the mid-19th century has been larger than the mean rate during the previous two millennia (high confidence). Over the period 1901–2010, global mean sea level rose by 0.19 [0.17 to 0.21] m.

    Since the early 1970s, glacier mass loss and ocean thermal expansion from warming together explain about 75% of the observed global mean sea level rise (high confidence). Over the period 1993–2010, global mean sea level rise is, with high confidence, consistent with the sum of the observed contributions from ocean thermal expansion due to warming, from changes in glaciers, Greenland ice sheet, Antarctic ice sheet, and land water storage. 

    Carbon and Other Biogeochemical Cycles

    The atmospheric concentrations of carbon dioxide (CO2), methane, and nitrous oxide have increased to levels unprecedented in at least the last 800,000 years. CO2 concentrations have increased by 40% since pre-industrial times, primarily from fossil fuel emissions and secondarily from net land use change emissions. The ocean has absorbed about 30% of the emitted anthropogenic carbon dioxide, causing ocean acidification.

    From 1750 to 2011, CO2 emissions from fossil fuel combustion and cement production have released 365 [335 to 395] GtC [gigatonnes – one gigatonne equals 1,000,000,000 metric tonnes] to the atmosphere, while deforestation and other land use change are estimated to have released 180 [100 to 260] GtC.

    Of these cumulative anthropogenic CO2 emissions, 240 [230 to 250] GtC have accumulated in the atmosphere, 155 [125 to 185] GtC have been taken up by the ocean and 150 [60 to 240] GtC have accumulated in natural terrestrial ecosystems. 

    Drivers of Climate Change

    The total natural RF [radiative forcing – the difference between the energy received by the Earth and that which it radiates back into space] from solar irradiance changes and stratospheric volcanic aerosols made only a small contribution to the net radiative forcing throughout the last century, except for brief periods after large volcanic eruptions.

    Understanding the Climate System and its Recent Changes

    Compared to AR4, more detailed and longer observations and improved climate models now enable the attribution of a human contribution to detected changes in more climate system components.

    Human influence on the climate system is clear. This is evident from the increasing greenhouse gas concentrations in the atmosphere, positive radiative forcing, observed warming, and understanding of the climate system.

    Evaluation of Climate Models

    Climate models have improved since the AR4. Models reproduce observed continental-scale surface temperature patterns and trends over many decades, including the more rapid warming since the mid-20th century and the cooling immediately following large volcanic eruptions (very high confidence).

    The long-term climate model simulations show a trend in global-mean surface temperature from 1951 to 2012 that agrees with the observed trend (very high confidence). There are, however, differences between simulated and observed trends over periods as short as 10 to 15 years (e.g., 1998 to 2012).

    The observed reduction in surface warming trend over the period 1998–2012 as compared to the period 1951–2012, is due in roughly equal measure to a reduced trend in radiative forcing and a cooling contribution from internal variability, which includes a possible redistribution of heat within the ocean (medium confidence). The reduced trend in radiative forcing is primarily due to volcanic eruptions and the timing of the downward phase of the 11-year solar cycle.

    Climate models now include more cloud and aerosol processes, and their interactions, than at the time of the AR4, but there remains low confidence in the representation and quantification of these processes in models.

    The equilibrium climate sensitivity quantifies the response of the climate system to constant radiative forcing on multi-century time scales. It is defined as the change in global mean surface temperature at equilibrium that is caused by a doubling of the atmospheric CO2 concentration.

    Equilibrium climate sensitivity is likely in the range 1.5°C to 4.5°C (high confidence), extremely unlikely less than 1°C (high confidence), and very unlikely greater than 6°C (medium confidence). The lower temperature limit of the assessed likely range is thus less than the 2°C in the AR4, but the upper limit is the same. This assessment reflects improved understanding, the extended temperature record in the atmosphere and ocean, and new estimates of radiative forcing. 

    Detection and Attribution of Climate Change

    Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in changes in some climate extremes. This evidence for human influence has grown since AR4. It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century.

    It is extremely likely that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in greenhouse gas concentrations and other anthropogenic forcings together. The best estimate of the human-induced contribution to warming is similar to the observed warming over this period. 

    Future Global and Regional Climate Change

    Continued emissions of greenhouse gases will cause further warming and changes in all components of the climate system. Limiting climate change will require substantial and sustained reductions of greenhouse gas emissions.

    The global ocean will continue to warm during the 21st century. Heat will penetrate from the surface to the deep ocean and affect ocean circulation.

    It is very likely that the Arctic sea ice cover will continue to shrink and thin and that Northern Hemisphere spring snow cover will decrease during the 21st century as global mean surface temperature rises. Global glacier volume will further decrease.

    Global mean sea level will continue to rise during the 21st century. Under all RCP scenarios the rate of sea level rise will very likely exceed that observed during 1971–2010 due to increased ocean warming and increased loss of mass from glaciers and ice sheets.

    Sea level rise will not be uniform. By the end of the 21st century, it is very likely that sea level will rise in more than about 95% of the ocean area. About 70% of the coastlines worldwide are projected to experience sea level change within 20% of the global mean sea level change.

    Climate change will affect carbon cycle processes in a way that will exacerbate the increase of CO2 in the atmosphere (high confidence). Further uptake of carbon by the ocean will increase ocean acidification.

    Cumulative emissions of CO2 largely determine global mean surface warming by the late 21st century and beyond. Most aspects of climate change will persist for many centuries even if emissions of CO2 are stopped. This represents a substantial multi-century climate change commitment created by past, present and future emissions of CO2.

    A large fraction of anthropogenic climate change resulting from CO2 emissions is irreversible on a multi-century to millennial time scale, except in the case of a large net removal of CO2 from the atmosphere over a sustained period.

    Surface temperatures will remain approximately constant at elevated levels for many centuries after a complete cessation of net anthropogenic CO2 emissions. Due to the long time scales of heat transfer from the ocean surface to depth, ocean warming will continue for centuries. Depending on the scenario, about 15 to 40% of emitted CO2 will remain in the atmosphere longer than 1,000 years.

    Sustained mass loss by ice sheets would cause larger sea level rise, and some part of the mass loss might be irreversible. There is high confidence that sustained warming greater than some threshold would lead to the near-complete loss of the Greenland ice sheet over a millennium or more, causing a global mean sea level rise of up to 7 m.

    Current estimates indicate that the threshold is greater than about 1°C (low confidence) but less than about 4°C (medium confidence) global mean warming with respect to pre-industrial. Abrupt and irreversible ice loss from a potential instability of marine-based sectors of the Antarctic Ice Sheet in response to climate forcing is possible, but current evidence and understanding is insufficient to make a quantitative assessment.

    Methods that aim to deliberately alter the climate system to counter climate change, termed geoengineering, have been proposed. Limited evidence precludes a comprehensive quantitative assessment of both Solar Radiation Management (SRM) and Carbon Dioxide Removal (CDR) and their impact on the climate system.

    CDR methods have biogeochemical and technological limitations to their potential on a global scale. There is insufficient knowledge to quantify how much CO2 emissions could be partially offset by CDR on a century timescale.

    Modelling indicates that SRM methods, if realizable, have the potential to substantially offset a global temperature rise, but they would also modify the global water cycle, and would not reduce ocean acidification.

    If SRM were terminated for any reason, there is high confidence that global surface temperatures would rise very rapidly to values consistent with the greenhouse gas forcing. CDR and SRM methods

    Climate change? Try catastrophic climate breakdown

    The message from the IPCC report is familiar and shattering: it’s as bad as we thought it was

    Already, a thousand blogs and columns insist the Intergovernmental Panel on Climate Change‘s new report is a rabid concoction of scare stories whose purpose is to destroy the global economy. But it is, in reality, highly conservative.

    Reaching agreement among hundreds of authors and reviewers ensures that only the statements which are hardest to dispute are allowed to pass. Even when the scientists have agreed, the report must be tempered in another forge, as politicians question anything they find disagreeable: the new report received 1,855 comments from 32 governments, and the arguments raged through the night before launch.

    In other words, it’s perhaps the biggest and most rigorous process of peer review conducted in any scientific field, at any point in human history.

    There are no radical departures in this report from the previous assessment, published in 2007; just more evidence demonstrating the extent of global temperature rises, the melting of ice sheets and sea ice, the retreat of the glaciers, the rising and acidification of the oceans and the changes in weather patterns. The message is familiar and shattering: “It’s as bad as we thought it was.”

    What the report describes, in its dry, meticulous language, is the collapse of the benign climate in which humans evolved and have prospered, and the loss of the conditions upon which many other lifeforms depend. Climate change and global warming are inadequate terms for what it reveals. The story it tells is of climate breakdown.

    This is a catastrophe we are capable of foreseeing but incapable of imagining. It’s a catastrophe we are singularly ill-equipped to prevent.

    The IPCC’s reports attract denial in all its forms: from a quiet turning away – the response of most people – to shrill disavowal. Despite – or perhaps because of – their rigours, the IPCC’s reports attract a magnificent collection of conspiracy theories: the panel is trying to tax us back to the stone age or establish a Nazi/communist dictatorship in which we are herded into camps and forced to crochet our own bicycles. (And they call the scientists scaremongers …)

    In the Mail, the Telegraph and the dusty basements of the internet, Friday’s report (or a draft leaked a few weeks ago) has been trawled for any uncertainties that could be used to discredit. The panel reports that on every continent except Antarctica, man-made warming is likely to have made a substantial contribution to the surface temperature. So those who feel threatened by the evidence ignore the other continents and concentrate on Antarctica, as proof that climate change caused by fossil fuels can’t be happening.

    They make great play of the IPCC’s acknowledgement that there has been a “reduction in surface warming trend over the period 1998–2012”, but somehow ignore the fact that the past decade is still the warmest in the instrumental record.

    They manage to overlook the panel’s conclusion that this slowing of the trend is likely to have been caused by volcanic eruptions, fluctuations in solar radiation and natural variability in the planetary cycle.

    Were it not for man-made global warming, these factors could have made the world significantly cooler over this period. That there has been a slight increase in temperature shows the power of the human contribution.

    But denial is only part of the problem. More significant is the behaviour of powerful people who claim to accept the evidence. This week the former Irish president Mary Robinson added her voice to a call that some of us have been making for years: the only effective means of preventing climate breakdown is to leave fossil fuels in the ground. Press any minister on this matter in private and, in one way or another, they will concede the point. Yet no government will act on it.

    As if to mark the publication of the new report, the Department for Business, Innovation and Skills has now plastered a giant poster across its ground-floor windows: “UK oil and gas: Energising Britain. £13.5bn is being invested in recovering UK oil and gas this year, more than any other industrial sector.”

    The message couldn’t have been clearer if it had said “up yours”. It is an example of the way in which all governments collaborate in the disaster they publicly bemoan. They sagely agree with the need to do something to avert the catastrophe the panel foresees, while promoting the industries that cause it.

    It doesn’t matter how many windmills or solar panels or nuclear plants you build if you are not simultaneously retiring fossil fuel production. We need a global programme whose purpose is to leave most coal and oil and gas reserves in the ground, while developing new sources of power and reducing the amazing amount of energy we waste.

    But, far from doing so, governments everywhere are still seeking to squeeze every drop out of their own reserves, while trying to secure access to other people’s. As more accessible reservoirs are emptied, energy companies exploit the remotest parts of the planet, bribing and bullying governments to allow them to break open unexploited places: from the deep ocean to the melting Arctic.

    And the governments who let them do it weep sticky black tears over the

    15 Things You Should Know About The New IPCC Report On Climate Science

    By Ryan Koronowski on September 27, 2013 at 12:49 pm

    The IPCC, or the Intergovernmental Panel on Climate Change, just released its latest scientific report that looks at what the world’s top experts understand about climate change. The review takes years to complete, and will be used for years as a vital resource for climate science.

    During a briefing on the report Friday morning organized by The Climate Group, three of the lead authors offered blunt summaries of their work:

    “Warming is unequivocal.” — Dennis Hartmann, one of the report’s coordinating lead authors, focusing on observations

    “From all of these lines of evidence, we conclude that humans are the dominant cause of changes in the climate system.” — Nathaniel Bindoff, a coordinating lead author, focusing on attribution of climate change

    “The oceans are still taking up heat,” even though warming has recently hit a speed bump at the surface — Jochem Marotzke a coordinating author, focusing on evaluating climate models

    Beyond that, what does the average person need to know about what’s in the report?

      1. It’s happening and we’re doing it: This report concludes that the earth is unequivocally changing, and the evidence is clear that humans have a large role in how it has changed over the last 60 years.

      1. 95-100 percent certain: Each of the IPCC’s last five big reports found that climate science has gotten increasingly certain that the planet is warming, and humans are the main cause. Scientists have a 95-100 percent certainty (“extremely likely”) that humans are causing temperatures to rise. Directly from the report: “It is extremely likely that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in greenhouse gas concentrations and other anthropogenic forcings together.” The report in 2001 was 66 percent certain, and the 2007 report was 90 percent certain. Scientific conclusions that cigarettes are deadly and that the universe is about 13.8 billion years old have similar levels of certainty.
      2. Warmest 30 years: The globe has already warmed 0.85°C from 1880 to 2012. 0.6°C of that warming happened since 1950, and “1983–2012 was likely the warmest 30-year period of the last 1400 years.”
      3. Pause? What pause?: The report itself does not mention the word “pause,” but does describe the long term and short term increase in temperature. Since 1880, the nine warmest years have happened since 1998. 1998 was a very warm year partially because a warm ocean caused by El Nino did not take up as much heat as normal, which made the atmosphere warmer. Without 1998′s anomaly, there is no “slowdown,” “plateau,” “pause,” or “speedbump.”
      4. IPCCAR5oceanacidificationgraphAcidifying oceans: The lower the pH, the more acidic something is. The pH levels of the ocean surface dropped by 0.1 since the start of the industrial era, “corresponding to a 26% increase in hydrogen ion concentration.” There’s been that big of an increase with a change of 0.1 because the scale is logarithmic.
      5. Global pollution ceiling: For the first time, the world’s leading climate scientists officially called for an absolute upper limit on greenhouse gas emissions to limit warming. To have a 66 percent chance of limiting warming to 2°C, the world can’t emit more than 1,000 gigatons of carbon dioxide, total. Or 800 gigatons when accounting for methane emissions and land use changes. For context, by 2011, humans had already emitted 531 gigatons of CO2. Known fossil fuel reserves represent 2,795 gigatons, meaning burning more than 10 percent of them pushes the world over 2° of warming.

    1. Seas rising and warming: Oceans, shallow and deep, are where most of the increases in heat energy goes, “accounting for more than 90% of the energy accumulated between 1971 and 2010.” Sea level has risen 19 centimeters since 1901, and “The rate of sea level rise since the mid-19th century has been larger than the mean rate during the previous two millennia.”
    2. One of the most scrutinized documents on the planet: More than 2,000 scientists worked on this report, which has been reviewed by government, industry, and environmental groups. It is one of the most scrutinized documents on the planet.
    3. Massive amounts of data: The report’s authors analyzed “9,200 peer-reviewed studies, undergirded by a staggering two million gigabytes of numerical data,” according to Jeff Nesbit.
    4. Summary for policymakers: 110 nations joined the review process leading up to the release of the report, which is officially known as the “Fifth IPCC Working Group Report on the Physical Science Basis of Climate Change.” This report is a summary for policymakers, whereas the full report will be over 1,000 pages. The final 5th Assessment will be released in 2014, along with other reports on vulnerability and mitigation.
    5. ‘Yet another wakeup call’: Secretary of State John Kerry said of the report: “This is yet another wakeup call: Those who deny the science or choose excuses over action are playing with fire.” He concluded that, “the response must be all hands on deck. It’s not about one country making a demand of another. It’s the science itself, demanding action from all of us.”
    6. Most comprehensive ever: President Obama’s top science adviser, John Holdren, said the report “represents the most comprehensive and authoritative synthesis of scientific knowledge about global climate change ever generated.”
    7. Senators should pay attention: U.S. Senator Ed Markey, co-chair of the Bicameral Task Force on Climate Change, said “If Senators truly followed the science in this report, we’d have more than 95 votes for action to match the more than 95 percent certainty that we are altering our planet for the worse.”
    8. Deniers can’t pick a response: As Penn State’s Distinguished Professor of Meteorology Michael Mann points out, climate deniers haven’t settled on a specific narrative to attack the report. Some think the report shows a smaller threat and less certainty, some think the report is too mild to mention, while some think that consensus is a bad thing. Yet the report contains more certainty, contains a seriously unmild set of predictions, and after analyzing large streams of data, has a robust consensus on a complex issue.
    9. Blistering pace: To put the report’s findings in perspective, Stanford scientists Noah Diffenbaugh and Chris Field found that the current pace of warming is happening 10 times faster than any time over the
