| Description: | A New Assessment of Global Warming. The data sets are publicly available. The most important indicator of global warming, by far, is the land and sea surface temperature record. This has been criticized in several ways, including the choice of stations and the methods for correcting systematic errors. The Berkeley Earth Surface Temperature study sets out to to do a new analysis of the surface temperature record in a rigorous manner that addresses this criticism. We are using over 39,000 unique stations, which is more than five times the 7,280 stations found in the Global Historical Climatology Network Monthly data set (GHCN-M) that has served as the focus of many climate studies. Our aim is to resolve current criticism of the former temperature analyses, and to prepare an open record that will allow rapid response to further criticism or suggestions. Our results include not only our best estimate for the global temperature change, but estimates of the uncertainties in the record. The Berkeley Earth Surface Temperature team includes statisticians, physicists, climate experts and others with experience analyzing large and complex data sets. |

Solid methodology as a good reference on segment on climate change. "The Berkeley Earth group has developed a new mathematical framework for producing maps and large-scale averages of temperature changes from weather station data for the purposes of climate analysis. The detail of the mathematical framework used is described in the draft paper "Berkeley Earth Temperature Averaging Process", available here. The Berkeley Earth mathematical framework allows one to include short and discontinuous temperature records, so that nearly all temperature data can be used. The framework contains a weighting process that assesses the quality and consistency of a spatial network of temperature stations as an integral part of the averaging process. This permits data with varying levels of quality to be used without compromising the accuracy of the resulting reconstructions. The Berkeley Earth averaging process presented is extensible to spatial networks of arbitrary density (or locally varying density) while maintaining the expected spatial relationships." |
