Former Chancellor Lord Lawson has called for an inquiry into the scandal, warning the credibility of UK science is at stake.
It comes amid pressure on the professor at the centre of the scandal to quit from his position at the CRU.
In one damning email, he appears to call the death of a climate change sceptic 'cheering news!'.
In other messages, researchers appear to be manipulating data and discussing how to dodge Freedom Of Information requests.
Another shows a climatologist from the U.S. admitting it was a travesty that the lack of global warming in recent years could not be explained.
When posted on the internet, the emails were accompanied by the anonymous statement: 'We feel that climate science is, in the current situation, too important to be kept under wraps.
'We hereby release a random selection of correspondence, code and documents.
'Hopefully it will give some insight into the science and the people behind it.'
