Berkeley Earth Study Confirms Global Warming Reality

Often questioned, often derided - global warming is a reality, according to the latest study.

Berkeley Earth Project's global warming study draws on over one billion weather station records to show historic one degree temperature rise

Pulling together a wider array of background material than any other independent review carried out before now, the study states, definitively, that temperatures have been on the ascent over the past few decades.

Compiled by the Berkeley Earth Project, the study drew on over one billion temperature records from a wealth of weather station archives, discovering an average one degree Centigrade rise when comparing 1950s data to that of today.

Berkeley Earth Project: Global Warming Study

The Berkeley Earth Project global warming study was given the go-ahead after the infamous Climategate affair, which challenged the true scale of global warming. It directly counters the issues raised by climate change cynics, such as the possibility of selective, cherry-picked data having been used in previous global warming verdicts.

It also asserts that the urban heat island effect - where city temperature readings cause local temperature records to spike - is genuine, but doesn't measurably impact on the global average, since urban sites only constitute one per cent of the Earth's area.

In conclusion, the researchers involved in the Berkeley Earth Project's climate change assessment highlight how their findings closely mirror those of other studies and, therefore, back them up.

"Our biggest surprise was that the new results agreed so closely with the warming values published previously by other teams in the US and the UK," Professor Richard A Muller, who established the Project, said in a statement. "This confirms that these studies were done carefully and the potential biases identified by climate change sceptics did not seriously affect their conclusions."

Global Warming Reality Confirmed

Compared to earlier studies, Professor Muller and his colleagues used data from 32,000 more weather stations and, so, got much more information on the conditions observed in South America, Antarctica, Africa and Asia in particular. This gave them the most comprehensive weather data set ever assimilated and meant that what the researchers termed ‘statistical uncertainty' could be avoided. Overall, they were able to show, more conclusively than anyone else, the reality of global warming.

The group's taken the unusual step of publishing the global warming data it's collated on its own website, rather than releasing it as a formal, published paper. Funding was supplied by sources that, before now, have given their support to the anti-climate change movement.

"We have looked at these issues in a straightforward, transparent way, and based on that, I would expect legitimate sceptics to feel their issues have been addressed", Professor Muller added.
