Global warming predictions prove accurate – Analysis of climate change modelling for past 15 years reveal accurate forecasts of rising global temperatures

Forecasts of global temperature rises over the past 15 years have proved remarkably accurate, new analysis of scientists’ modelling ofclimate change shows.

The debate around the accuracy of climate modelling and forecasting has been especially intense recently, due to suggestions that forecasts have exaggerated the warming observed so far – and therefore also the level warming that can be expected in the future. But the new research casts serious doubts on these claims, and [...]

The World Bank warns that a 4 degree C global temperature increase would devastate the world’s economy

Report says climate change could decimate agriculture, cause global health problems

from US News:

“A 4 degree Celsius world is so different from the current one that it comes with high uncertainty and new risks that threaten our ability to anticipate and plan for future adaptation needs,” he writes.

A global temperature increase like one estimated by the World Bank would lead to “the inundation of coastal cities; increasing risks for food production, [...]

Weaker sun will not delay global warming: study

LONDON (Reuters) – A weaker sun over the next 90 years is not likely to significantly delay a rise in global temperature caused by greenhouse gases, a report said Monday.

The study, by Britain’s Meteorological Office and the university of Reading, found that the Sun’s output would decrease up until 2100 but this would only lead to a fall in global temperatures of 0.08 degrees Celsius.

Scientists have warned that more extreme [...]

Climate Skeptic Admits He Was Wrong to Doubt Global-Warming Data


Climate skeptics perform independent analysis, finally convinced Earth is getting warmer
By John Timmer | Published about 2 hours ago

Last week, a project called Berkeley Earth released drafts of its findings. The project was started by a physicist, Richard Muller, who had previously expressed doubts about the mathematical rigor of climate science; it received funding from a variety of sources, including the Department of Energy and foundations set up by Bill [...]

March coolest globally in more than 15 years


Remote Sensing Systems has released their satellite measured temperature data for the month of March 2011.

March 2011 ended up as the coolest March globally since March of 1994. The actual global temperature anomaly for the lower troposphere last month was negative 0.026 C.

This is also the first month since June of 2008 that the global temperature anomaly was in the negative.
