The Berkeley Earth Surface Temperature project

“Berkeley Earth Surface Temperature” was a project that intended to review the voracity of the official temperature records.  In it’s inception it was enthusiastically supported by many skeptics including Mr. Watts of “What's Up With That” blog fame.

The results are coming out and it looks as though the climatologists have be presenting us with accurate information.  So this begs the question: When are committed AGW “skeptics” going to start taking climatologists seriously.


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).

Papers Submitted for Peer Review (October 2011)

The Berkeley Earth team has now submitted four papers for peer review. We are making these preliminary results public, together with our programs and data set, in order to invite additional scrutiny. 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

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) is now publicly available here.
Berkeley Earth Analysis Programs (October 2011) are now publicly available here.  
Two Page Summary of Findings (October 2011) is available here.

Richard Littlemore at DesmogBlog has an excellent write up that I’d like to share a bunch of:

“The paper was partly funded by the Koch brothers, famous for the pollution their industries spew and for the money they spend funding everything from climate change denial to the founding of the Tea Party. "Leading scientists" involved in the paper included people such as Richard Muller and Judith Curry, a man apparently out of his depth in climate science and a woman dangerously in love with her growing reputation as a contrarian. Many people took one look at the funder and the guest list and concluded that anything produced by their Berkeley Earth Surface Temperature (BEST) group was going to be tainted fodder for the denier hoards.
We were wrong.

The BEST paper, an effort to confirm or debunk whether the <b>urban heat island (UHI) effect</b> was skewing climate records, has affirmed - again - that global temperature records are accurate and worrisome. In doing so, they also confirmed that UHI fan Anthony Watts is, well, a silly man who refuses to let solid, peer-reviewed science get in the way of his enthusiasms.”

“That said, Muller and Curry deserve credit for standing by good science. And the other contributors to the paper (Charlotte Wickham, Don Groom, Robert Jacobsen, Saul Perlmutter, robert Rohde, Arthur Rosenfeld and Jonathan Wurtele) deserve an equally enthusiastic round of applause for keeping the ship of science steady even with Koch money rattling around in the hold.

The risk they took, accepting that money and associating with Muller and Curry when the two seemed not to care about their professional reputations, has been well-rewarded. We have, again, decisive confirmation of the obvious - that anthropogenic global warming is undeniable. And we have it from the unlikeliest source.
At some point, you might even think that this would inspire someone in government to take seriously the notion that we should do something about it … no? We live in hope.”

Over at they have another excellent article explaining the details of the
Berkeley Earth Surface Temperature Study: “The effect of urban heating on the global trends is nearly negligible”

A paper submitted for peer review by the Berkeley Earth Surface Temperature study (BEST) finds that urban heating has an influence on global temperature trends that is “nearly negligible” and that what effect has been observed is even slightly negative, which is to say that temperature trends in urban areas are actually cooler than the trends measured at rural sites, and that the Earth's land surface has warmed approximately 1°C on average since 1950.

The Berkeley Earth Surface Temperature team has reported the results of their first studies of surface temperature records. They have submitted four papers for publication, you can get copies of them here.
In my opinion it’s clear what Watts is really upset about — the results from the Berkeley team have confirmed that the other main global temperature estimates (NASA GISS, NOAA/NCDC, and HadCRU) got it right, and that station siting/urban heat island effects are not responsible for any of the observed temperature increase. The real reason all these analyses (including Berkeley’s) show temperature rise is: the globe is warming.

Last but not least, Ben at WottsUpWithThat takes some parting shots and offers a list of links for further edification:
