"Despite the decadal slowdown in the rise of average surface temperature, a longer-term warming trend is still evident. Each of the last three decades was warmer than any other decade since widespread thermometer measurements were introduced in the 1850s," the publication, Climate Change Evidence and Causes, said.
Scientists have been investigating reasons for the slowdown in temperature rises. Peer-reviewed papers over the last year have suggested 17 sun-dimming volcanic eruptions since 2000, "unusual" trade winds in the Pacific Ocean burying surface heat deep underwater and the world's oceans absorbing greater amounts of heat in recent years may have contributed.
Thomas Stocker, the co-chair of working group one of the UN's climate science panel, said at the launch of the Intergovernmental Panel on Climate Change's landmark report last September that the recent slowdown in surface temperature rises was not significant because it was over too short a period of time. "Climate relevant trends should not be calculated for periods of less than 30 years," he said.....
