IPCC climate report: six things we've learned

Guardian: * Scientists are more certain than ever that humanity is to blame for rising temperatures. The head of the United Nations' World Meteorological Organisation, Michel Jarraud, said "it is extremely likely that changes in our climate system in the past half century are due to human influence." The report says: "Human influence on the climate system is clear. This is evident from the increasing greenhouse gas concentrations in the atmosphere, positive radiative forcing, observed warming, and understanding...

Global Warming Is Real IPCC Repeats, Now Can We Do Something about It?
2013-09-27 14:57:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: Global warming is "unequivocal." Sea levels are creeping up at the fastest rate in 2,000 years. Concentrations of CO2 in the atmosphere have reached "levels unprecedented in at least the last 800,000 years" (or before modern humans evolved). Most importantly "human influence on the climate system is clear" and "continued emissions of greenhouse gases will cause further warming." Those are some of the key messages in the "Summary for Policymakers" of the physical science of global warming from the...
Key findings of IPCC report on climate change

Associated Press: The Intergovernmental Panel on Climate Change, an international body established by the U.N. in 1988, presented a summary of its latest assessment on climate change on Friday. Here are the key findings: Global warming is "unequivocal," and since the 1950's it's "extremely likely" that human activities have been the dominant cause of the temperature rise. Concentrations of carbon dioxide and other greenhouse gases in the atmosphere have increased to levels that are unprecedented in at least...

Why has geoengineering been legitimised by the IPCC?

Guardian: Today marked an important punctuation mark in the story of humanity's attempts to get to grips with climate change as the Intergovernmental Panel on Climate Change (IPCC) published its summary for policymakers (pdf here). Climate sceptic journalists and interest groups will be making the most of the tiniest surprises and variations in the climate scientists' new representation of the state of their art. But the evidence is largely unsurprising. For all the talk of a "hiatus" in warming, the IPCC...

IPCC report: Scientists are 95% certain humans are responsible for climate change
2013-09-27 13:17:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: Scientists are more certain than they have ever been that humans are causing global warming, according to the most comprehensive report ever conducted into climate change, which predicts "with 95 per cent certainty" that peoples greenhouse gas emissions are heating the world. This is the main finding of the UN Intergovernmental Panel on Climate Change's (IPCC) fifth assessment report, known as AR5, which was published in Stockholm this morning. The degree of certainty leaves little doubt that...
