London (CNN) — An independent study of global temperature records has reaffirmed previous conclusions by climate scientists that global warming is real.

The new analysis by the Berkeley Earth Surface Temperature project examined 1.6 billion temperature reports from 15 data archives stretching back over 200 years in an effort to address scientific concerns raised by climate skeptics about the data used to inform reports published by the Intergovernmental Panel on Climate Change (IPCC).

Researchers found “reliable evidence” of a rise in average world land temperatures of one degrees Celsius — or 1.8 degrees Fahrenheit — since the mid-1950s.

[NOTE:  To attempt to quell any straggling skeptics, the researchers have published their methodology, entire data set, and software code, in a fully transparent and well-designed research protocol.   Here’s the link:   http://berkeleyearth.org]

“Our biggest surprise was that the new results agreed so closely with the warming values published previously by other teams in the United States and the UK,” professor Richard A. Muller, Berkeley Earth’s scientific director said in a statement.

“This confirms that these studies were done carefully and that potential biases identified by climate change skeptics did not seriously affect their conclusions,” Muller added.

Climate skeptics have consistently challenged the findings of studies by NASA, the National Oceanic and Atmospheric Administration (NOAA) and the UK’s University of East Anglia’s Climate Research Unit, whose research is used by the IPCC.
