Alarming video shows Earth’s temperature has risen 1C since 1950s

A new study led by a controversial physicist has claimed that the global land temperature has risen by 1C since the 1950s.

Richard Muller and his team from the Berkeley Earth Surface Temperatures project (BEST) from Berkeley University in California used data from 1800 to 2009 to present their “irrefutable” proof in the form of an alarming video.

BEST data was taken from 1.6 billion temperature-archived records dating back to the 1800s from 15 sources around the world that shows deviation from the mean temperature over two centuries and overall global warming since the industrial revolution.

To highlight their findings, the researchers put all the data into one alarming video of a warming world visualising surface temperature records, and the 1C rise in temperature matches estimates by the world’s respected climate watchers who maintain official records.

These include the Met Office with the University of East Anglia, Nasa's Goddard Institute for Space Studies in New York and the US National Oceanic and Atmospheric Administration.

However, the mutiny within the BEST ranks has cast doubt on their findings, as Professor Judith Curry, who was one of ten experts attempting to compile the definitive temperature data, has claimed that it had been “tarnished” by Muller.

Curry, of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology, in the US, also said that Muller was “overselling” the results in favour of global warming and she has even threatened to quit the project.

She said that their data actually showed average world temperatures had “paused” since the late 1990s, and a graph published on the project’s website depicting temperatures from 1850 to 2006 appeared to “hide the decline”.

“My hope is that this will win over those people who are properly sceptical,” the Daily Mail quoted Muller as saying.

“Some people lump the sceptical in with the deniers and that makes it easy to dismiss them, because the deniers pay no attention to science,” he added.
