Update: Researchers from University of California, Berkeley confirmed reports that global temperatures have risen by 1 degree Celsius

Massive Study Proves Climate Change is No Hoax - Technorati Green: "The team included a 2011 Nobel Prize winner in Physics, Saul Perlmutter and various climatologists and statisticians. Compiling a huge open database of temperature records, researchers found a striking correlation with earlier American and British studies and the data clearly supports the conclusions that warming is occurring.

This study is the most comprehensive and thorough to date and focused on some nagging questions about the debate.
According to this statement:

" 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.""
