The Department of Energy’s Carbon Dioxide Information Analysis Center estimates that 2010 was a record year for global CO₂ emissions from fossil fuel combustion and cement manufacture. The increase is about 5.9% above the 2009 global estimate. Emissions in the U.S.

New studies both confirm global warming and warn there is little time left to keep warming below 2˚C from pre-industrial levels, the target needed to avert dangerous climate change. Berkeley Earth has submitted four papers for peer review that confirm the amount of warming determined by earlier studies.

A new study in Journal of Climate determines that the urban heat island effect may contribute only 2-4% of global warming.

In a September 7 press conference, experts from the nonprofit Climate Communication project discussed the connection between global extreme weather and climate change. In recent decades, as the climate has warmed, extreme weather has become more frequent. This extreme weather (which the U.S.

Authors of a recent article in Climatic Change determined how a 1.2˚C global-mean temperature increase relative to present would affect the frequency of temperature extremes in the future.
