Earth warmer by 1ºC since 1950s
The earth’s average temperature has risen by 1C since the 1950s, says a controversial study.
For their study, researchers, led by Professor Richard Muller from the Berkeley Earth Surface Temperatures project (BEST) at Berkeley University in California, used data from 1800 to 2009 to present their “irrefutable” proof.
The was taken from 1.6 billion temperature archived records dating back to the 1800s from 15 sources around the world. It shows deviation from the mean temperature over 200 years and overall global warming since industrial revolution.
To highlight their findings, the BEST researchers put all 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, the Daily Mail reported.
However, mutiny within the BEST ranks has cast doubt on the findings, much to the delight of climate change sceptics.
Professor Judith Curry, one of 10 experts attempting to compile the definitive temperature data, claimed it had been “tarnished” by Prof. Muller “overselling” the results in favour of global warming.
Prof. Curry said 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”.
But, Prof. Muller said: “My hope is that this will win over those people who are properly sceptical.”
