How much has climate change altered weather so far?

New Scientist: This is surprisingly unclear. Some things that seemed fairly certain in the last report in 2007, no longer appear to be. For instance, the 2007 assessment confidently reported that "more intense and longer droughts have been observed over wide areas since the 1970s." This led to dire warnings of droughts to come, including an IPCC prediction that "between 75 and 250 million people [in Africa] are projected to be exposed to an increase in water stress due to climate change" by the 2020s. But the...

Climate change: The absolute basics
2013-09-27 10:31:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: The planet is definitely warming. Despite a recent slowing in the pace, the atmosphere is 0.7 °C warmer than in 1950. The oceans are also warming. It is virtually certain most of this is due to human influences, mainly our emissions of carbon dioxide from burning carbon-based fuels, and deforestation. Warming has been strongest in the Arctic, where sea ice is disappearing and permafrost is melting. The extent of sea-ice loss is unprecedented in 2000 years and very likely due to man-made climate...

UN panel delivers landmark climate change report

USA Today: Global warming is "unequivocal" and it is "extremely likely" that humans are the primary contributors to this warming, according to a report released Friday morning in Stockholm by the U.N.-created Intergovernmental Panel on Climate Change (IPCC), the world's top climate research group. "Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in changes in some climate...

Climate change will hit poor countries hardest, study shows

Guardian: Low-income countries will remain on the frontline of human-induced climate change over the next century, experiencing gradual sea-level rises, stronger cyclones, warmer days and nights, more unpredictable rains, and larger and longer heatwaves, according to the most thorough assessment of the issue yet. The last major UN assessment, in 2007, predicted runaway temperature rises of 6C or more by the end of the century. That is now thought unlikely by scientists, but average land and sea temperatures...
Does the IPCC's Climate Change Report Still Matter?

LiveScience: More than 250 climate scientists are gathering in Sweden this week to finalize the Intergovernmental Panel on Climate Change's (IPCC) latest assessment on the sView gallery."Greenland's Petermann Glacier birthed a massive new iceberg in June 2012.

But elsewhere, some experts say it's time to reassess the entire IPCC process, which includes examining the...
