    fox news climate change

    Fox News has been known for their extensive climate change denial (see here, here, here and here), despite living in an age where 97 percent of scientific papers support the human-driven phenomenon. Yet the right-leaning news channel’s views may be contagious: A new study has found that the more time viewers spend consuming conservative media, the more skeptical they become of climate science.

    The paper, published in the journal “Public Understanding of Science,” found that the key link between climate change denial and conservative outlets like Fox News and Rush Limbaugh was an inherent distrust of scientists. “Conservative media use decreases trust in scientists which, in turn, decreases certainty that global warming is happening,” the study says.

    Conversely, researchers found that consumption of nonconservative media (i.e. CNN, MSNBC and NPR) had the opposite effect.

    Americans’ support for climate change is on the rise — nearly 60 percent of people said they worry a great deal or fair amount about the problem earlier this year, up from 51 percent in 2011. President Obama has also been more vocal about the warming planet in recent months, although Americans are split on their approval of his plans.

    The paper isn’t the first to identify the connection between Fox and climate denial, but expands on earlier observations, particularly that “the more Americans use conservative media, the less certain they are that global warming is happening.”

    The study was conducted in two phases, beginning with 2,497 respondents in 2008, of which 1,036 were reinterviewed in 2011. The study incorporated variables including political ideology, religiosity and certain demographics.

    2012 Climate Change Report From NOAA Reveals Rising Seas, Snow Melt And More Warming

    WASHINGTON — A new massive federal study says the world in 2012 sweltered with continued signs of climate change. Rising sea levels, snow melt, heat buildup in the oceans, and melting Arctic sea ice and Greenland ice sheets, all broke or nearly broke records, but temperatures only sneaked into the top 10.

    The National Oceanic and Atmospheric Administration on Tuesday issued a peer-reviewed 260-page report, which agency chief Kathryn Sullivan calls its annual “checking on the pulse of the planet.” The report, written by 384 scientists around the world, compiles data already released, but it puts them in context of what’s been happening to Earth over decades.

    “It’s critically important to compile a big picture,” National Climatic Data Center director Tom Karl says. “The signs that we see are of a warming world.”

    Sullivan says what is noticeable “are remarkable changes in key climate indicators,” mentioning dramatic spikes in ocean heat content, a record melt of Arctic sea ice in the summer, and whopping temporary melts of ice in most of Greenland last year. The data also shows a record-high sea level.

    The most noticeable and startling changes seen were in the Arctic, says report co-editor Deke Arndt, climate monitoring chief at the data center. Breaking records in the Arctic is so common that it is becoming the new normal, says study co-author Jackie Richter-Menge of the U. S. Army Corps of Engineers’ Cold Regions Research and Engineering Laboratory in Hanover, N.H.

    Karl says when looked at together, all the indicators show a climate that is changing over the decades. Individually, however, the story isn’t as simple.

    Karl says surface temperatures haven’t risen in the last 10 years, but he notes that is only a blip in time due to natural variability. When looking at more scientifically meaningful time frames of 30 years, 50 years and more than 100 years, temperatures are rising quite a bit, Karl said. Since records have been kept in 1880, all 10 of the warmest years ever have been in the past 15 years, NOAA records show.

    Depending on which of four independent analyses are used, 2012 ranked the eighth or ninth warmest year on record, the report says. Last year was warmer than every year in the previous century, except for 1998 when a record El Nino spiked temperatures globally. NOAA ranks 2010 as the warmest year on record.

    They don’t have to be records every year, Karl says.

    Overall the climate indicators “are all singing the same song that we live in a warming world,” Arndt says. “Some indicators take a few years off from their increase. The system is telling us in more than one place we’re seeing rapid change.”

    While the report purposely doesn’t address why the world is warming, “the causes are primarily greenhouse gases, the burning of fossil fuels,” Arndt says.

    The study is being published in a special edition of the Bulletin of the American Meteorological Society.

  • Coastal Erosion problems at Bar Beach

    Valley has now added the Old Bar Beach foreshore to its list of issues.

    The foreshore is disappearing faster than my wages, with twenty metres of beach front lost in the past decade. This loss of sand has accelerated in the past couple years due to storms and other elements, with more than three metres of beach front lost in the past 18 months. Old Bar is part of an erosion problem facing many parts of the east coast- line from Sydney to Byron Bay. Coastal towns and villages are working with their Councils and other agencies to save these major assets.

    Old Bar is a seaside town near Taree. The town has already witnessed the demolition of two homes located at the southern end of Lewis Street due to erosion. These two homes were the subject of development applications to rebuild on the rear of their blocks; however, the development applications had to be fast tracked by Taree Council. The Council had to act quickly with demolition orders, as the rapid loss saw one of the homes with part of its structure hanging over the cliff face.

    Another two neighbouring homes appear certain to head the same way, as they also succumb to the rapid erosion. The problem is highlighted at the site of one the demolished homes, which was originally on land that was 5,500 square metres in size and purchased in 2001. This property has pristine views of the ocean, and the original residence was located a healthy 27 metres from the back fence. The fast moving erosion problem has seen this distance vanish.

    Lewis Street backs onto the eroding areas, and its residents are expressing major concerns. Experts predict the beach front street may have a five to ten year life span at the current rate of erosion.

    The crisis has caused Old Bar residents to form an action group: Old Bar Beach Sand Replenishment Group Inc. under the Presidency of Elaine Pearce. The group is urging immediate work to protect the foreshore and dunes, to eliminate any further loss.

    The group formed in late 2008 and has completed a Draft Management Plan, met local Federal Member Rob Oakeshott, Greater Taree City Council, and Worley Parsons, the consultants currently compiling a report on behalf of the Council as a Coastal Hazard Assessment.

    “We have covered a lot of ground since we formed,” said Elaine Parsons. “Currently we have compiled our own solution and are applying for a Federal grant to head towards a permanent solution.”

    The action group is advised by Tim Minty, a local geological engineer who has decades of experience studying and stopping erosion problems.

    “If something is not done now, then the beach will be gone, and there is a risk the sea will enter Racecourse Creek,” said Minty. “The shore-line is now eighty metres closer to the dune.”

    Minty has suggested a solution: building a series of groins (breakwalls) at right angles to the shore-line, which will capture the sand and severely slow the erosion. Minty believes that six to eight groins varying in length from 15 to 45 metres are necessary to overcome the problem. He has estimated the cost to be between $800,000-$900,000 – something, he says, that can easily be put into place.

    “The system can be either an Elcorock (bags) or Tetra pods (interlocking) – both will be effective.”

    Resident Mark Searles, a local surveyor, is also a major contributor to the solution plan. He has been surveying the shore-line regularly and reports that his records show five to six metres of the dunes/beach have been lost in the past two years. This is in contrast to the original predications in 1997 that a metre a year would be lost.

    The Greater Taree City Council’s coastal management plan developed in 1992 is now under review, with a new coastal management line to be established citing a minimum distance for future developments.

    With some affected residents heading to the legal fraternity to be advised about their rights of compensation, the disaster appears headed to the courts for a decision. Who is responsible? The Greater Taree City Council, or the various agencies of the Federal or New South Wales Governments for approving these developments?

    Residents claim all three agencies were aware of the future losses of coast-line as far back as the mid 1990s and are legally responsible – a situation denied by all three bodies. Residents whose homes are now under threat are alarmed and annoyed at having to bear the cost of reports, after receiving written advice from Council for engineering assessments on their properties.

    “We believe the Council should cover the costs of any reports,” said Elaine Parsons. “The owners of the affected properties see it as a dismissal of responsibilities by our bureaucrats.”

    It may sound alarmist, but if the current rate of erosion continues, in 20 years we will see the shore-line decrease and the elimination of the caravan park, amenities around the reserve, the entirety of Lewis Street, Pacific Parade, part of Rose Street and the Old Bar Public School.

    So it is evident that a solution has to be found soon.

    In the early 1990s the Council recognised there was a problem and successfully built a groin-wall to divert Racecourse Creek, which at the time was eroding the fore-dunes in front of the reserve and houses located in Lewis Street. The re-direction of the creek created a build-up of sand located in the south. Since that action – which worked well – conditions have changed, with the barrier now only visible during storms.

    During the last decade, the dunes south of Racecourse Creek at Old Bar have slowly changed along with the natural coastal system, which is now a residential area.

    With the coastlines of New South Wales eroding, it is puzzling that there has been an absence of action from governments.

    Our beaches are one of the lifebloods of our tourist industry, and if the erosion is allowed to go unchecked we will have reduced revenue and a reduced amount of venues for our growing population to enjoy.

    Where does the responsibility stop? Does it rest with all levels of government, with owners of the properties or with the developers who applied and were granted permission to erect buildings?

    If history repeats itself, it is evident they will all blame each other; however, the bottom line is that we must protect our coast-line and the current residential areas from further erosion.

    Many blame climate change, while others say the change in currents and weather conditions are related to a cycle that happens every five decades. Whatever the reason, we simply cannot afford to procrastinate.

    Old Bar is not unique with its problems. Laurieton, near Port Macquarie, is becoming a victim, and recently the foreshore of Sydney had a block of units under threat after it lost an enormous amount of sand, exposing the units’ foundations.

    Protection of our coast-line has been on government agendas, as they have instigated many laws to protect marine life, vegetation etc. The Greater Taree City Council is awaiting a report on a Coastal Hazard Assessment from Worley Parsons – a group of consultants engaged to investigate and make recommendations about our coastline.

    Director of Planning and Building, Graham Gardiner says: “We are aware and concerned about the Old Bar situation. Whatever recommendations are made by the Worley Parsons report, Council will discuss what the next steps will be. Council has fast tracked the demolition orders and pending development application/s of the affected residents.

    “In the circumstances we have done everything possible and cannot do any more until we do an analysis of the Worley Parsons report due in March.”

    Residents are working hard to stop the pending demise of their beachside village, and as a tight community they are united to gain a positive outcome.

     

  • Climate report warns extreme weather events are now the norm

    Climate report warns extreme weather events are now the norm

    By North America correspondent Ben Knight, wires

    Updated 6 hours 42 minutes ago

    Climate scientists in the United States say extreme weather events and warming temperatures are the new norm.

    The American Meteorological Society has released its annual snapshot of the world’s climate, which concludes disastrous weather events like Hurricane Sandy in the US and droughts and floods in Australia, Africa and South America will become more frequent.

    The report lists a raft of indicators that show a continuously warming planet where ice sheets and glaciers will keep shrinking, and sea and land temperatures will keep rising to record levels.

    Last year was a record-breaking year for the world’s climate, with new extremes for sea levels, temperatures, snow coverage and ice melts.

    Arctic ice levels reached record lows in 2012, and the polar region is warming at twice the rate of the rest of the planet, however on a positive note at the other end of the world, Antarctica’s climate remained relatively stable and sea ice cover reached a record maximum.

    Key Points

    • Extreme weather to become the norm: hurricanes and floods
    • Ice sheets and glaciers to keep shrinking
    • Sea and land temperatures to keep rising to record levels
    • The world to become warmer
    • More droughts and unusual rains expected

     

    The report also stated the world’s highest levels of greenhouse gases were released by burning fossil fuels last year.

    Some 384 scientists from 54 countries contributed to the report, covering all aspects of the planet, from the depths of the oceans to the stratosphere.

    Last year was among the top 10 on record for global land and surface temperature since modern data collection began.

    ‘Planet as whole becoming warmer place’

    “The findings are striking,” Kathryn Sullivan, acting administrator of the National Oceanic and Atmospheric Administration (NOAA) told AFP.

    “Our planet as a whole is becoming a warmer place.”

    Michael Mann, a leading US climatologist at Pennsylvania State University who was not involved in the research, added: “It’s hard to read the report and not be led to the conclusion that the task of reducing carbon emissions is now more urgent than ever.”

    Globally, 2012 ranked as the eighth or ninth warmest year since records began in the mid-to-late 1800s, according to four independent analysts cited by the study.

    “Surface temperatures in the Arctic are increasing at a rate about two times faster than the rest of the world,” Jackie Richter-Menge, research civil engineer with the US Army Corps of Engineers, said.

     

    Meanwhile, permafrost temperatures reached record highs in northern Alaska and 97 per cent of the Greenland ice sheet showed some form of melt, four times greater than the average melt for this time of year.

    The melt is also contributing to rising sea levels.

    Average global sea level reached a record high in 2012, 3.5 centimetres above the 1993 to 2010 average.

    “Most recently, over the past seven years or so, it appears that the ice melt is contributing more than twice as much to the global sea level rise compared with warming waters,” Jessica Blunden, climatologist at NOAA’s National Climatic Data Center, said.

    Scientists say the data should be of concern to people living in coastal areas and that weather patterns from the past can no longer be used to predict the future.

    The peer-reviewed report did not go into the causes for the trends but experts said it should serve as a guide for policymakers as they prepare for the effects of rising seas and warming weather on communities and infrastructure.

    The amount of carbon dioxide emissions from burning fossil fuels also hit new highs, after a slight decline in recent years that followed the global financial crisis.

    For the first time, in Spring 2012, the atmospheric CO2 concentration exceeded 400 parts per million (ppm) at seven of the 13 Arctic observation sites, the report said.

    Global average carbon dioxide reached 392.6 ppm, a 2.1 ppm increase from 2011, it said.

    Droughts and unusual rains struck different parts of the globe last year and the the worst drought in the past three decades was noted in north-eastern Brazil.

    The Caribbean observed a very wet dry season and the Sahel had its wettest rainy season in 50 years, according to the report.

    Dr Sullivan said the findings “caution us, perhaps, to be looking at a likely future where extremes and intensity of some extremes are more frequent and more intense than what we have accounted for in the past.”

  • Rising Sea Levels Will Be Tough To Reverse

    Rising Sea Levels Will Be Tough To Reverse

    SustainableBusiness.com News

    Based on current emissions and global warming trends, the US already has “locked in” sea level increases of at least four feet above current levels before the next century, according to a Climate Central analysis.

    That’s enough to submerge more than half the population in 316 US coastal cities and towns when high tide rolls in. Those communities currently are home to about 3.6 million people.

    “By the end of this century, if global climate emissions continue to increase, that may lock in 23 feet of sea level rise, and threaten 1,429 municipalities that would be mostly submerged at high tide,” writes Ben Strauss, vice president for Climate Impacts and Director of the Program on Sea Level Rise at Climate Central. “Those cities have a total population of 18 million. But under a very low emissions scenario, our sea level rise commitment might be limited to about 7.5 feet, which would threaten 555 coastal municipalities: some 900 fewer communities than in the high-emissions scenario.”

    Right now, the water is encroaching on coastal developments in the US by about one inch per decade, but Climate Central anticipates increases of closer to one foot per decade in the near-term future.In its analysis, Climate Central considers a place to be “threatened” if at least half of the current population lives below the sea levels expected at high tide by 2100.

    Florida is particularly vulnerable, but Louisiana, New Jersey and North Carolina also are home to plenty of threatened communities under that definition.

    If current carbon pollution trends continue, Climate Central suggests that more than 100 cities and towns will be threatened in each of these states.

    Nationally, the biggest threatened cities include Miami, Virginia Beach, Va.; Sacramento, Calif.; and Jacksonville, Fla.

    The graphic below shows the areas that would be flooded at high tide in 2100, under the scenario described above. The threatened areas are represented in blue:

     

    If you use a lower threshold for giving communities a  threatened stats –- say, if 25% of the current population lives below the projected high-tide sea levels for 2100 — you can add major cities including Boston, Long Beach, Calif., and New York City to the list.

    The analysis doesn’t account for any solutions that cities may be putting into place for protection, such as the network of levees and flood barriers in New Orleans or a series of measures that have been proposed for New York City. It does suggest that areas such as South Florida will be especially difficult to protect, because of its geological makeup.

    The impact would be reduced significantly under a low-emissions scenario that calls for a halt to global emissions growth by 2020, followed by rapid reductions and clean-up actions. But that is extremely unlikely given the current political climate.

    The average rate of global sea level increases was about one half-foot per century during the 20th century, just half the current rate.

    Middle-of-the-road projections suggest average per-century increase of about 5 feet by 2100, notes Climate Central.

    “Such rates, if sustained, would realize the highest levels of sea level rise contemplated here in hundreds, not thousands of year — fast enough to apply continual pressure, as well as threaten the heritage, and very existence, of coastal communities everywhere,” writes Strauss.

    The Climate Central analysis was published in the Proceedings of the National Academy of Sciences. Read the complete report:

  • Soil Carbon ‘Blowing in the Wind’

    Soil Carbon ‘Blowing in the Wind’

    Aug. 6, 2013 — Australian soils are losing about 1.6 million tonnes of carbon per year from wind erosion and dust storms affecting agricultural productivity, our economy and carbon accounts, according to new research.


    Share This:

    Top soil is rich in nutrients and carbon but is increasingly being blown away by events such as the ‘Red Dawn’ in Sydney in 2009.

    When wind lifts carbon dust into the atmosphere it changes the amount and location of soil carbon.

    Some carbon falls back to the ground while some leaves Australia or ends up in the ocean.

    CSIRO research scientist Dr Adrian Chappell and an international team of experts in wind erosion and dust emission recently calculated the extent of these carbon dust emissions.

    “Carbon stored in our soils helps sustain plant growth. Our modelling shows that millions of tonnes of dust and carbon are blowing away, and it is uncertain where all that ends up,” Dr Chappell said.

    “We need to understand the impact of this dust carbon cycle to develop more accurate national and global estimates of carbon balances and to be able to prepare for life in a changing climate.

    “Australia’s carbon accounts, and even global carbon accounts, have not yet taken wind or water erosion into consideration and when this happens it could have significant impacts on how we manage our landscapes. While soil organic carbon lost through dust is not a major contributor to Australia’s total emissions, it is a major factor in our deteriorating soil health.”

    Carbon is an essential ingredient for the healthy soils which underpin Australia’s capability to produce enough food to feed 60 million people.

    Understanding the movement of carbon through the landscape is a necessity if we are to improve the quality of our soils and support farmers and land managers to store carbon.

    This is not an issue for Australia alone. Other countries will also need to know the fate of their wind-blown carbon; countries like the USA and China with larger dust emissions will likely face similar challenges when including wind borne dust in their carbon accounting.

    With the frequency and intensity of dust storms likely to increase in Australia, the impact of wind erosion would also increase.

    This redistribution of carbon needs to be better understood so we can improve our land management practices to better protect our soils.

    Recent research estimated that the ‘Red Dawn’ dust storm that passed over the eastern coast of Australia on 23 September 2009 cost the economy of New South Wales A$300 million, mainly for household cleaning and associated activities.

    The research paper “Soil organic carbon dust emission: an omitted global source of atmospheric CO2” was published in the latest issue of the journal Global Change Biology.
