NOAA: Global warming 'undeniable'

Research shows “undeniable” warming trends
A comprehensive review of 10 key climate indicators, including sea level, glacier melt and air temperatures, by 300 scientists in 48 countries shows unmistakable signs of global warming, the group says in a report released by the U.S. National Oceanic and Atmospheric Administration. The report does not address possible reasons for the trend. The Toronto Star/The Associated Press (7/29) , (7/28)
Warming world – A clearer picture of global warming since the 1850s
(The Economist) CHARTS showing the warming of the Earth normally look like spaghetti thrown across the page. This chart, adapted from a compendious “State of the climate” report published by America’s National Oceanic and Atmospheric Administration this week, simplifies things by offering only decadal averages, and making clear the uncertainties by showing the 95% confidence ranges on those averages.
Global warming ‘undeniable,’ world report says
(National Post) The past decade was the warmest on record and, as glaciers melt, severe storms batter cities and heat waves increase, more than 300 scientists have concluded that global warming is “undeniable.”
A new report, published by the U.S. National Oceanic and Atmospheric Administration (NOAA) Thursday and compiled by investigators from 48 different countries including Canada, identified 10 climate indicators that are clearly linked to changing surface temperatures and they “all tell the same story.”
“Glaciers and sea ice are melting, heavy rainfall is intensifying and heat waves are more common. . . . There is now evidence that more than 90% of warming over the past 50 years has gone into our oceans,” said Deke Arndt, co-editor of the report and manager of the NOAA Climate Monitoring Branch.
The study suggests continued warming will transform how societies currently function, as coastal cities, water supplies, agriculture and infrastructure will all be threatened.
“People have spent thousands of years building society for one climate and now a new one is being created — one that’s warmer and more extreme,” the report says.

Global warming pushes 2010 temperatures to record highs
Scientists from two leading climate research centres publish ‘best evidence yet’ of rising long-term global temperatures
(The Guardian) Global temperatures in the first half of the year were the hottest since records began more than a century ago, according to two of the world’s leading climate research centres.
Scientists have also released what they described as the “best evidence yet” of rising long-term temperatures. The report is the first to collate 11 different indicators – from air and sea temperatures to melting ice – each one based on between three and seven data sets, dating back to between 1850 and the 1970s.
