| Description | The UN's Intergovernmental Panel on Climate Change published in 2007 is widely considered the most authoritative report on global warming.
However a new report looking at the science that has been produced since found that temperature rises could be even higher because of increasing amounts of pollution in the atmosphere, speeding up of melting glaciers, collapsing ecosystems and acidification of the oceans.
The Climate Change Science Compendium 2009 looked at 400 scientific reports released through peer-reviewed literature, or from research institutions.
It said an increase in global greenhouse gas concentrations made a rise of between 1.4 and 4.3 degrees Celsius (2.5 to 7.75 F) above pre-industrial temperatures more likely – this is above the range of between 1 to 3 degrees C (2 to 5.4 F) that could lead to the end of summer Arctic sea ice and the eventual melting of the Himalayan glaciers and the Greenland ice sheet, the report said.
