Online — Berkeley Earth (http://berkeleyearth.org) was conceived by Richard and Elizabeth Muller in early 2010 when they found merit in some of the concerns of skeptics.
They organized organized a group of scientists to reanalyze the Earth’s surface temperature record, and published their initial findings in 2012.
Berkeley Earth became an independent non-profit 501(c)(3) in February 2013.
From 2010-2012, Berkeley Earth systematically addressed the five major concerns that global warming skeptics had identified, and did so in a systematic and objective manner.
The first four were potential biases from (1) data selection, (2) data adjustment, (3) poor station quality, and (4) the urban heat island effect.
Their analysis showed that these issues did not unduly bias the record. More details on the website’s About Page at: http://berkeleyearth.org/about/

Berkeley Earth has published five scientific papers setting out the main conclusions of the study to date:
- A New Estimate of the Average Earth Surface Land Temperature Spanning 1753 to 2011
- Berkeley Earth Temperature Averaging Process (commonly referred to as the “Methods” paper) and its appendix
- Influence of Urban Heating on the Global Temperature Land Average
- Earth Atmospheric Land Surface Temperature and Station Quality in the United States
- Decadal Variations in the Global Atmospheric Land Temperatures
The Berkeley Earth team is making these preliminary results public, together with the analysis programs and data set in order to invite additional scrutiny as part of the peer review process.
