Copenhagen must be a turning point. Our children won't forgive us if we fail | Gordon Brown | guardian.co.uk

Let no one be in any doubt about the overwhelming scientific evidence that underpins the Copenhagen conference. The Intergovernmental Panel on Climate Change brings together over 4,000 scientists from every corner of the world. Their recent work has sharpened, not diminished, the huge and diverse body of evidence [like what, specifically?] of human-made global warming. Its landmark importance cannot be wished away by the theft of a few emails from one university research centre. On the contrary, the pernicious anti-scientific backlash that the emails have unleashed has exposed just what is at stake.

The purpose of the climate change deniers' campaign is clear, and the timing no coincidence. It is designed to destabilise and undermine the efforts of the countries gathering in Copenhagen today.

A bigger rise of 3-4C — the smallest increase we can prudently expect to follow inaction — would parch continents, turning farmland into desert. Half of all species could become extinct, untold millions of people would be displaced, whole nations drowned by the sea. The controversy over emails by British researchers that suggest they tried to suppress inconvenient data has muddied the waters but failed to dent the mass of evidence on which these predictions are based.
...But whereas putting a man on the moon or splitting the atom were born of conflict and competition, the coming carbon race must be driven by a collaborative effort to achieve collective salvation.

This editorial will be published tomorrow by 56 newspapers around the world in 20 languages including Chinese, Arabic and Russian. The text was drafted by a Guardian team during more than a month of consultations with editors from more than 20 of the papers involved. Like the Guardian most of the newspapers have taken the unusual step of featuring the editorial on their front page.
