No more global warming?

[Louis VI the Fat]

Well?

I am a complete sucker for sensationalist media. First of all I watched 'An Inconvenient Truth', and I was sure global warming was happening and it was going to be serious. But sometimes I see things like this and I'm not so sure. I just don't have the core knowledge to make a serious decision, and I suspect 99% of the population are the same.

But what do the fine, educated minds of the Backroom think?

One can try to replace an inductive method by a deductive method. That is, to try not to discover global warming from temperature recordings, but from simple principles.

The amount of CO2 in the atmposphere is a constituant of the earth's climate.
So any decrease or increase of CO2 has a climatological result.

Few scientists would dispute this.

From there, it is really simple. CO2 is a greenhouse gas, so releasing it has an effect. And not just on earth, for really spectacular global warming effects, try Venus:

A hot year, or ten cold years, neither prove nor disprove global warming anymore than a particular cold day in July does. What matters is that one constituent of the earth's climate is drastically changed through human working, in a particularly short amount of time.
