UC Berkeley Study: Global Warming Is Real

In the most comprehensive study of historical temperature records to date, an independent investigation led by researchers at the University of California, Berkeley said Friday global warming is real.
The researchers in the study say skeptics no longer have a basis for denial of global warming, as a list of more than a billion records from 15 sources dating back to the 1800s was complied in support of the study.
From The State Column:
The researchers calculated the average global land temperature has risen by around 1C since the mid-1950s. These calculations agree with previous estimates from major groups that maintain official records on the world’s climate. These groups include NASA’s Goddard Institute for Space Studies in New York, the U.S. National Oceanic and Atmospheric Administration (NOAA), and the Met Office’s Hadley Centre, with the University of East Anglia, in the UK.
According to the study, the accuracy of the findings as well as those of previous studies were unaffected from previous criticisms of poor quality of the temperature stations often used to take readings.
The chairman of the research team, Richard A, Muller, wrote in a letter to the Wall Street Journal:
Again, our statistical methods allowed us to analyze the U.S. temperature record separately for stations with good or acceptable rankings, and those with poor rankings (the U.S. is the only place in the world that ranks its temperature stations). Remarkably, the poorly ranked stations showed no greater temperature increases than the better ones. The mostly likely explanation is that while low-quality stations may give incorrect absolute temperatures, they still accurately track temperature changes.
Researchers in the study also say the criticism that results are skewed by the urban heat island effect (a phenomena that causes asphalt-filled cities to absorb more heat than rural areas) did not affect measurements, because urban areas only take up about one percent of the Earth's surface.
Muller said that the study did not make an independent assessment of how much global warming is man-made, but also said he hopes the findings can help settle arguments over the topic as a whole.
The project was organized by the Santa Barbara-based non-profit organization Novim, and received funding from the Fund for Innovative Climate and Energy Research and the Department of Energy’s Lawrence Berkeley Lab.

Maybe you should do a little more investigation before jumping on the left-wing bandwagon that mankind is evil and killing the Earth, which demands a more authoritarian government and more taxes. I realize that no one is teaching the students at Annenberg to be objective, but try doing it on your own...unless it affects your grades, which is might.
"Climategate II? 'Science-Settling' Study 'Proving' Global Warming Allegedly Shows None"
http://newsbusters.org/blogs/tom-blumer/2011/10/30/climategate-ii-suppos...
"A week ago (at BizzyBlog; at NewsBusters), I noted how Charleston Daily Mail blogger Don Surber quickly determined through all of a few minutes of Internet research that Berkeley professor Robert Muller, who convinced Washington Post Plumline blogger Brad Plumer that he was a 'climate skeptic,' has been a believer in human-caused global warming since the early 1980s.
"Muller's pretense to have held beliefs differing from his true past may be the least of his problems. A story breaking in the UK contends that results obtained by the prof's BEST (Berkeley Earth Surface Temperatures) project team, instead of 'settling the debate' in favor of warmists, showed that global warming 'has stopped.' If so, this is potentially as explosive as the 'hide the decline' conspiracy uncovered almost two years ago when the Climategate emails surfaced. ....
"...a leading member of Prof Muller’s team has accused him of trying to mislead the public by hiding the fact that BEST’s research shows global warming has stopped.
"Prof Judith Curry, who chairs the Department of Earth and Atmospheric Sciences at America’s prestigious Georgia Institute of Technology, said that Prof Muller’s claim that he has proven global warming sceptics wrong was also a ‘huge mistake’, with no scientific basis.
"Prof Curry is a distinguished climate researcher with more than 30 years experience and the second named co-author of the BEST project’s four research papers.
"Her comments, in an exclusive interview with The Mail on Sunday, seem certain to ignite a furious academic row. She said this affair had to be compared to the notorious ‘Climategate’ scandal two years ago.
"In fact, Prof Curry said, the project’s research data show there has been no increase in world temperatures since the end of the Nineties – a fact confirmed by a new analysis that The Mail on Sunday has obtained. ...."

Political consensus and science should not be confused.
Now, will you publish a correction?
The study is from Berkeley. Of course, they would use already discredited and non-public sources and claim that anthropological global warming is real. Why?
