2013-09-13 MALMÖ – On September 26, the United Nations Intergovernmental Panel on Climate Change will present the summary of its most recent assessment report, the fifth in 23 years. Although the IPCC is not perfect – it famously predicted that all Himalayan glaciers would be gone in 2035, when the more likely year is 2350 – its many experts generally give us the best information on the fractious issue of global warming. Because of extensive leaks, the report’s contents are mostly known.
