Lost for words

What about the majority of the Arctic?
What about all the floating ice?
What about the fact that the earth isn't getting warmer anyway?
What about the fact that humans are responsible for a tiny proportion of CO2 output?
What about the fact that CO2 barely registers on the scale of greehouse gases.
What about the fact that the "greenhouse effect" is a fantasy that has never been proved?

Floating ice - what about it? is a potential sea-level rise of 10m from less than half of antarctica's ice sheets not enough for you? Arctic ice melting will effect the thermohaline circulation. The ice sheet on Greenland melting (note the 'land' bit) would cause a sea-level rise. Greenland is very very big.
Warming - The earth is getting warmer at the moment (i.e. it is going through a warming phase - read the IPCC report)
CO2 output by humans - well it may be a tiny proportion but it's the most important one
CO2 as a GHG - it is not the most powerful GHG, but it is by far and away the predominant one - methane is more powerful but is so inconsequential in volume that until gas hydrates are released by the warming tundra you should really not ignore CO2 input - 'CO2 barely registers on the scale of greehouse gases' does not actually mean anything at all
Greenhouse effect as a fantasy that has never been proved - well that's just a Melanie Phillips type of argument. It has never been proved that the earth is not flat. And the greenhouse effect is now as much a part of scientific fact as AIDS and gravity. To deny it's existence is daft, unless you can prove otherwise, which I doubt you can.

I personally don't give a shit as the world will carry on once the human race and many other species have died out, including me. But those who think it's all just a conspiracy backed up by lies and bad science are just being silly.
