In November 2009, an event occurred that would change the course of climate activism around the world. The huge servers of the University of East Anglia were illegally hacked into, and more than 1,000 emails and documents were stolen and used as a tool for climate-change deniers.

The damage Climategate delivered to the international negotiations on climate action cannot be overlooked. We also must be careful not to give it too much credit either.

Now that the 15 year global warming "pause" is confirmed dead, it is fascinating, if at times painful, to look back at the sharp disagreements among important scientific figures in the climate community.

As of January 1st, the 15-year running mean surface temperature change now starts from the much cooler 1999, and gives a very different picture.

Prices in Europe's carbon emissions trading scheme have collapsed this year, in part because there were too many allowances in the system starting off, threatening the future of the whole market.

There was a time when I couldn't understand what motivated writers like Margaret Wente to stand so firmly against such clear and solid science. The psychology of "confirmation bias" has provided the answer for me.

A week before the climate talks began, a new collection of 5,000 e-mails from climate researchers surfaced, apparently part of the same set obtained and then leaked in 2009 in the so-called "Climategate" affair.

The climategate hacker sounds like he (or she, or they) belongs to the unfortunate category of misguided saviours.

The UK police force tasked with investigating the hacking of emails and documents from the Climatic Research Unit at the University of East Anglia seems to have quietly de-prioritized its investigation earlier this year.

A new batch of nearly 230,000 illegally hacked emails is up online in the same old places the last batch went up in November of 2009, being taken totally out of context. It seems like old times.

A fresh tranche of private emails exchanged between leading climate scientists throughout the last decade was released online on Tuesday. The unauthor...

Since "climategate" first broke the news two years ago, American efforts to enact effective climate policy at the federal level have been significantly undermined by a confluence of events.
