From WNYC in New York, this is NPR's on the media. I'm Brooke Gladstone.

And I'm Bob Garfield. This week, the United Nations Climate Summit kicked off in Copenhagen,

billed as the biggest environmental meeting in history.

The aim of its thousands of delegates is to seal a worldwide deal to head off dangerous global warming.

But that was before they had to contend with this. to seal a worldwide deal to head off dangerous global warming.

But that was before they had to contend with this.

Tonight, a global investigation into what's being called Climate Gate.

Hacked emails that some say call into question the very science behind global warming. The emails spanning the last decade were written by scientists based at the University

of East Angoli as Climate Research Unit in the UK.

In some, they discuss tricks to fudge temperature records, and another scientist wishes he

could beat up a leading climate change denier.

And they also suppressed inconvenient information.

This was fuel for the decades-old debate that has been heating up faster than the planet.

Global warming skeptics saying those emails suggest that scientists may have worked together

to manipulate global warming data.

Defenders say those emails are being used out of context.

Andrew Revkin, environment reporter for the New York Times, himself cited in about 14 of those

thousand emails as a reporter, not a participant, says the skeptics conspiracy theories are wrong and that the case for the

role we humans play in the warming of the planet is rock solid. However, he says there are

legitimate grounds for debate over when or whether we need to prepare for utter catastrophe.

If you are a foe of restrictions on greenhouse gases, you can find plenty of real science out there to support your contention.

The rate of sea level rise in this century is still largely undetermined.
