IPCC climate change report: a scientist's story

Guardian: I have spent this week in Stockholm, going through the laborious but fascinating process of approving the Summary for Policymakers of the IPCC [Intergovernmental Panel on Climate Change] Working Group I report, the most comprehensive scientific assessment of climate change written to date. The report is science meets policy. I'm on the science side. With my 259 colleagues, we spent three years writing this report, went through two rounds of reviews, considered nearly 55,000 comments, and wrote...

UN climate change report points blame at humans

CNN: The world's getting hotter, the sea's rising and there's increasing evidence neither are naturally occurring phenomena. So says a report from the U.N. International Panel on Climate Change, a document released every six years that is considered the benchmark on the topic. More than 800 authors and 50 editors from dozens of countries took part in its creation. The summary for policymakers was released early Friday, while the full report, which bills itself as "a comprehensive assessment of the physical...

Climate change report: "extremely likely" humans are responsible
2013-09-27 11:11:00| Climate Ark Climate Change & Global Warming Newsfeed
CNN: Human activity has caused at least half of climate change in the last half-century, hundreds of scientists say. They are 95% certain of this, the surest they've ever been, says a United Nations report published Friday. That activity? Driving cars, running power plants on coal and oil, torching swathes of forestland and debris; anything involving burning carbon-based fuels and emitting greenhouse gases. We are seeing the consequences already in extreme weather patterns, particularly drought and...

IPCC climate report: humans 'dominant cause' of warming

BBC: A landmark report says scientists are 95% certain that humans are the "dominant cause" of global warming since the 1950s. The report by the UN's climate panel details the physical evidence behind climate change. On the ground, in the air, in the oceans, global warming is "unequivocal", it explained. It adds that a pause in warming over the past 15 years is too short to reflect long-term trends. The panel warns that continued emissions of greenhouse gases will cause further warming and...

IPCC report: environmentalists guide to climate change

Telegraph: Energy from the sun arrives as visible and ultraviolet light, which is absorbed by the Earth. Some of this energy is released from Earth again as heat. Greenhouse gases in the atmosphere trap this heat and bounce it back towards the Earth's surface. Laboratory experiments show that carbon dioxide can absorb and then emit heat, while satellite observations reveal that the amount of heat being released into the atmosphere is changing. Some greenhouse gases, such as methane and nitrous oxide,...
