*The messages, which span 13 years, show a few scientists in a bad light, being rude or dismissive. An investigation is underway, but there’s still plenty of evidence that the earth is getting warmer and that humans are largely responsible.
*Some critics say the e-mails negate the conclusions of a 2007 report by the Intergovernmental Panel on Climate Change, but the IPCC report relied on data from a large number of sources, of which CRU was only one.
*E-mails being cited as “smoking guns” have been misrepresented. For instance, one e-mail that refers to “hiding the decline” isn’t talking about a decline in actual temperatures as measured at weather stations. These have continued to rise, and 2009 may turn out to be the fifth warmest year ever recorded. The “decline” actually refers to a problem with recent data from tree rings.
