Seventy academies from around the world urged governments meeting in Bonn for climate talks from June 1-12 to take more account of risks to the oceans in a new UN treaty for fighting global warming due to be agreed in Copenhagen in December.
The academies said rising amounts of carbon dioxide, the main greenhouse gas emitted mainly by human use of fossil fuels, were being absorbed by the oceans and making it harder for creatures to build protective body parts.

Senator MILNE (Tasmania) (10.44 a.m.)-I move:
(1) That the Senate notes that:
(a) the 4th assessment report of the Working Group I of the Intergovernmental Panel on Climate Change (IPCC), published in February 2007, indicates that sea levels will rise by between 0.18 metres to 0.59 metres by the end of the century and that these projections do not include the full effects of changes in ice sheet flow because a basis in published literature is lacking;
(b) the next IPCC report on impacts, adaptation and vulnerability, to be released in April 2007, is expected to conclude that there is a medium confidence, that is a 50 per cent chance, that the Greenland and Antarctic ice sheets would be committed to partial deglaciation for a global average temperature increase greater than 1 to 2 C, causing a sea level rise of 4 to 6 metres over centuries to millennia;
(c) recent scientific research, published too late for inclusion in the IPCC reports, suggest that sea levels are rising more quickly than previously thought and many scientists, including Dr James Hansen, head of Atmospheric Research for the National Aeuronautics and Space Administration, warn that a warming of 2 to 3 C could melt the ice sheets of West Antarctica and parts of Greenland resulting in a sea level rise of 5 metres within a century;

Russia has been a rather puzzling actor in the complicated diplomatic game which resulted in the Kyoto protocol, and which will be played out again in Copenhagen in December. Climate warming doesn’t make headlines, and has so far not been a big concern, between Moscow and Vladivostok. What prompted Russian leaders to ratify Kyoto was the prospect of making good money from emissions trading, rather than conviction that man-made climate change is a real phenomenon and a threat to society.
Carbon emissions must start falling in 2015 to keep warming to 2C: scientists
Carbon emissions must start falling in 2015 to keep warming to 2C: scientist
Mark Henderson, Robin Pagnamenta | May 29, 2009
WORLD carbon emissions must start to decline in only six years if humanity is to stand a chance of preventing dangerous global warming, a group of 20 Nobel prize-winning scientists, economists and writers has declared.
The United Nations climate summit in Copenhagen in December must agree to halve greenhouse-gas emissions by 2050 to stop temperatures from increasing by more than 2C, the St James’s Palace Nobel Laureate Symposium concluded.
While even a 2C temperature rise will have adverse consequences, a bigger increase would create “unmanageable climate risks”, according to the St James’s Palace memorandum, signed by 20 Nobel laureates in physics, chemistry, economics, peace and literature.
The temperature target “can only be achieved with a peak of global emissions of all greenhouse gases by 2015”, the document said. If emissions continue to rise after that date, the required cuts would become unachievable.
700.000 homes at sea rise risk
700,000 homes at sea rise risk : “More than 700,000 Australian homes could be flooded by rising sea levels and up to $150 billion
worth of homes, property and infrastructure were at risk, the Federal Department of Climate Change told a parliamentary inquiry
yesterday. Nearly all Australians would be affected – 80% of the Australian population lives in the coastal zone, and approximately
711,000 addresses are within three kilometres of the coast and less than six metres above sea level, the department said in a
submission to the inquiry into the effects of climate change on coastal settlements. The Intergovernmental Panel on Climate Change
has predicted that sea levels could rise between 0.18m and 0.59m over the next 100 years. The department said that even a small rise
would dramatically change Australia’s coastline. It is estimated that erodible coasts will recede one metre for every one centimetre
rise in sea level, the report said. Storm surges will exacerbate coastal erosion.”

“NASA chief climate scientist Jim Hansen is no stranger to controversy. One of the world’s most eminent climate modellers, Hansen is director of the New York-based Goddard Institute of Space Science, run by US government space agency NASA and home to some of the world’s best-known climate models.
As a member of the US National Academy of Science, it was Hansen’s testimony on climate change given to congressional committees in the 1980s that triggered early public awareness of the problem of global warming.
