Last week two international conferences addressed this issue and the contrast between them could not have been starker.
The first in Copenhagen, billed as "an emergency summit on climate change" and attracting acres of worldwide media coverage, was explicitly designed to stoke up the fear of global warming to an unprecedented pitch. As one of the organisers put it, "this is not a regular scientific conference: this is a deliberate attempt to influence policy".
What a striking contrast this was to the second conference ... in New York, organised by the Heartland Institute under the title Global Warming: Was It Ever Really A Crisis?. In Britain (and in the rest of the world ...) this received no coverage at all, apart from a sneering mention by The Guardian, although it was addressed by dozens of expert scientists, not a few of world rank, who for professional standing put those in Copenhagen in the shade.
The message of this gathering was that the scare over global warming has been deliberately stoked up for political reasons and has long since parted company with proper scientific evidence.

The Heartland Institute most certainly is not an objective scientific think thank, but a lobby organisation - promoting individual liberty, limited government and free markets. But I do not believe for a single moment that the Copenhagen conference was more objective.
