Poster (January 2013)
A Comparative Analysis of Monthly Temperature Homogenization in the Conterminous United States, by Zeke Hausfather, Robert Rohde, Mathhew J. Menne, Calude N. Williams, and Jun Zhang
Two page summary of findings (July 2012)
A two page summary of the main findings in the Results paper is available here.
Results paper now online (July 2012)
The Berkeley Earth team has submitted a fifth paper for publication; it has received journal peer review, and we are now posting it for a wider peer review from the scientific community. The new results paper is available here.
Temperature record by location (July 2012)
Berkeley Earth has added an online feature where you can look up temperature records by location (city, state or country) - available here.
Berkeley Earth Analysis Charts (March 2012)
The Berkeley Earth team has redone our analysis of the new data set, and summary charts are available here.
These annual and decadal comparison plots are normalized so that all four curves have zero mean over the arbitrarily chosen time period 1950 to 1980. We are now using the true GISS land average and the HadCRU simple average for these respective groups, as those data products have a more similar methodology to our own for averaging over land.
Updated dataset (February 2012)
The updated (February 2012) Berkeley Earth merged dataset can be accessed here. All files are in Text format, but if there is enough interest we can also provide them in Matlab. File sizes are approximately 600 MB for the data, 937 MB for the flags, 550 MB for the sources.
Berkeley Earth Analysis of Full Data Set (October 2011)
The Berkeley Earth team has completed the analysis of the full data set, and summary charts are available here. The Berkeley Earth team has already started to benefit from feedback from our peers, so these figures are more up-to-date than the figures in our papers submitted for peer review (see below).
Berkeley Earth Land Temperature Anomaly Video (October 2011)
The Berkeley Earth team has also put together a video representation of our analysis of global land-surface temperature from 1800 to the present, available here.
Berkeley Earth Data Set (October 2011)
The Berkeley Earth data set is now publicly available here.
Berkeley Earth Analysis Programs (October 2011)
The Berkeley Earth analysis programs are now publicly available here.
Two Page Summary of Findings (October 2011)
A two page summary of the main findings is available here.
Richard Muller's testimony before congress (March 2011)
Dr. Richard Muller, chair of the Berkeley Earth Surface Temperature study, was asked to testify before the U.S. House of Representatives Committee of Science, Space and Technology at their hearing on climate change on 31 March, 2011.
A copy of Richard's testimony is available here.
Berkeley Earth Summary Document (September 2010)
A short summary of the Berkeley Earth Surface Temperature project is available here.
