Earth surface temperature chart, Berkeley

26 October 2011 – The Berkeley Earth team has bad news on temperatures for the earth. The consensus has been right, despite the accusations of poor data gathering stations and impact of the urban heat island effect, which the team has set out specifically to address.

Among the findings were that about one third of temperature gathering sites around the world showed cooling, but two thirds showed warming. The impact of the urban heat island effect is negligible because of the small total area involved – less than one per cent, the Berkeley Earth team said. The study does not show whether the warming is due to human impact. Next it will study ocean temperatures  More ..

Following are the first four papers submitted for peer review (October 2011)

The four papers are:

  1. Berkeley Earth Temperature Averaging Process
  2. Influence of Urban Heating on the Global Temperature Land Average
  3. Earth Atmospheric Land Surface Temperature and Station Quality in the United States
  4. Decadal Variations in the Global Atmospheric Land Temperatures

The Berkeley Earth team  is making these preliminary results public, together with programs and data set, in order to invite additional scrutiny, the team says.
