Gozra: the sun hasn't increased its output noticably. And while the amount of CO2 we've added is small in proportion to the entire atmosphere, that doesn't mean it doesn't have an effect. All we've done is strengthen the already existing greenhouse effect by a few degrees- a very small part of the overall effect, more or less in proportion to the amount of gas we've added.

Problem is that few degrees can have fairly major implications.

And yeah, global warming probably will lead to a mini ice age for Europe. Climate's weird like that.

AT: from everything I've read the planet should get *colder* internally as it gets older, eventually ceasing tectonic activity altogether (though by the time that happens the human race will likely be long extinct).
