'Overwhelming' consensus for manmade warming: review
A comprehensive assessment of climate change research has found an overwhelming consensus among scientists that recent warming is human-induced.

The study looked at 12,000 climate research papers from the last two decades, and identified 4,000 that stated a position on the cause of recent global warming.

Those papers, which were all published between 1991 and 2011, were written by more than 10,000 scientists.

Just over 97 per cent of the scientists agreed that man-made warming was a reality.

'Best estimate' for impact of melting ice on sea level rise
Researchers have published their most advanced calculation for the likely impact of melting ice on global sea levels.

The EU funded team say the ice sheets and glaciers could add 36.8 centimetres to the oceans by 2100.

Adding in other factors, sea levels could rise by up to 69 centimetres, higher than previous predictions.

The researchers say there is a very small chance that the seas around Britain could rise by a metre.

Beat me to it on the 97% story.

Talk on radio this morning that the twister/tornado in America may be the strongest one the state has ever experienced. Logic tells me that this may or may not be related to climate change but my unscientific gut feeling says something different.

If this is the strongest tornado ever seen in the State of Oklahoma then it was truly awesome. Moore, Oklahoma ( center of the damage path) already held the record for the highest wind ever recorded. In 1999, a tornado with a wind speed of 318 mph struck Moore. If global warming is making these storms more powerful or more frequent or both then God help us all.

UN climate change draft report finds it is 95 per cent likely that global warming is caused by humans

A leaked draft of a major United Nations climate change report has revealed scientists are almost certain human activity is causing global warming.

Drafts of the Intergovernmental Panel on Climate Change's (IPCC) fifth assessment report says it is 95 per cent likely that humans were the principal cause of warming.

The findings mark a 5 per cent increase from 2007's fourth assessment report.

The document will also attempt to explain why the increase in global temperatures has slowed since 1998, despite greenhouse gas concentrations reaching record highs.

In May, a report published in the journal Nature Geoscience said the planet was warming slower in the short term than previously projected.

Global sea level rise temporarily dampened by 2010-11 Australia floods

Three atmospheric patterns came together above the Indian and Pacific Oceans in 2010 and 2011. When they did, they drove so much precipitation over Australia that the world's ocean levels dropped measurably.

Unlike other continents, the soils and topography of Australia prevent almost all its precipitation from flowing into the ocean.

The 2010-11 event temporarily halted a long-term trend of rising sea levels caused by higher temperatures and melting ice sheets, according to a team of researchers at the National Center for Atmospheric Research (NCAR) in Boulder, Colo., and other institutions.

Now that the atmosphere's circulation has returned to its previous patterns, the seas are again rising.

Not directly about climate change, but ...
World-first pilot plant to turn carbon dioxide into rock

A research pilot plant in Newcastle will trial world-first technology that turns carbon emissions into bricks and pavers for the construction industry.

The mineral carbonation technology copies and accelerates the earth's own way of sinking carbon.

The University of Newcastle, chemical giant Orica and carbon innovation company GreenMag Group have spent six years researching how to permanently and safely dispose of carbon dioxide.

...

"We could be making millions of tonnes of bricks and pavers which really could be green products for the future," he said.

He says the project is about permanently transforming carbon dioxide, not just storing it in the ground.

IF ALL THE ICE MELTED

Perhaps as high as 80 degrees Fahrenheit on a global average!! Quite a game changer.
Tell the kids, and their kids , and their kids, ... your sorry.
