The following post from Skeptical Science is by Dana Nuccitelli.
The main purpose of Skeptical Science is to debunk climate-related myths. To achieve this purpose, we created the Arguments Database, and examined what the scientific literature says about each argument. Recently we addressed a number of myths and misleading statements made by Dr. John Christy in his testimony to US Congress. In watching the associated Congressional hearing, we were disappointed to see many American politicians repeating the same myths which our database has debunked. It appears that these myths have become very pervasive in American politics, and are being used to justify some very anti-science legislation.
As a consequence we've decided that it would be worthwhile to apply our Arguments Database to certain politicians who frequently perpetrate the myths we have debunked. We have created a Climate Myths from Politicians Database which pairs quotes from politicians with the corresponding rebuttal in the Arguments Database, and the one-line summary of each rebuttal:

The emails reveal that leading climate "experts" deliberately destroyed records, manipulated data to "hide the decline" in global temperatures.
What the Science Says
The "decline" refers to a decline in northern tree-rings, not global temperature, and is openly discussed in papers and the IPCC reports.
Joe Barton (R-TX)Climate Myth
There are just as many glaciers that are growing that are shrinking.What the Science Says Most glaciers are retreating, posing a serious problem for millions who rely on glaciers for water.

Recent events have uncovered extensive evidence from the Climate Research Unit (CRU) at the University of East Anglia in England, which involved many researchers across the globe, discussing the destruction, alterations and suppression of data that did not support global warming claims. Leaked exchanges detail attempts to alter data that is the basis of climate modelling. These exchanges reveal actions that constitute a serious breach of scientific ethics.
What the Science Says
A number of investigations have cleared scientists of any wrong-doing in the media-hyped email incident.
James Inhofe (R-OK)Climate Myth
The claim that global warming is caused by man-made emissions is simply untrue and not based on sound science.What the Science Says Multiple sets on independent observations find a human fingerprint on climate change.
Dana Rohrabacher (R-CA)Climate Myth
The Oregon Institute of Science and Medicine, the OISM, released the names of some 31,478 scientists who signed a petition rejecting the claims of human-caused global warming.What the Science Says The 'OISM petition' was signed by only a few climatologists.
Currently the database is limited to U.S. politicians, but in the near future we will expand it internationally. We hope it will be a useful resource to continue debunking these long-lived myths, and help convince politicians to stick to the facts. Never let it be said that we at Skeptical Science aren't optimists!
