Dueling Climate Change Stories

First this:

The world is heading for the next major climate change conference in Cancun later this year on course for global warming of up to 3.5C in the coming century, a series of scientific analyses suggest. The failure of last December's UN climate summit in Copenhagen means that cuts in carbon emissions pledged by the international community will not be enough to keep the anticipated warming within safe limits.

Two analyses of the Copenhagen Accord and its pledges, by Dr Sivan Kartha of the Stockholm Environment Institute, and by the Climate Action Tracker website, suggest that, with the cuts that are currently promised under Copenhagen, the world will still warm by 3.5C by 2100. Such a rise would be likely to have disastrous effects on agricultural production, water availability, natural ecosystems and sea-level rise across the world, producing tens of millions of refugees.

And then this:

A high-level inquiry into the Intergovernmental Panel on Climate Change found there was “little evidence” for its claims about global warming.

It also said the panel had emphasised the negative impacts of climate change and made “substantive findings” based on little proof.

I think I'll go with number 2.
