Show me a genuine climate change model that takes into account 5+billion years, shows that humanity is the cause and then perhaps you will sell it. (What you can't?)
Oh and just to point out - ice caps melt, sea levels rise, more methane, tempatures rise, more evaporation(of the now larger surface area of sea), rains more, CO2 is once more "locked" into sea water while being taken out of the atmosphere, temp falls, ice forms at the caps, sea level falls, less evaporation, tempature rises, ice caps melt...... this only breaks if the oceans boil! (wiki carbon cycle and I won't deny this might not be strictly accurate but it's close)
Over 3000 years the highest tempature in the North Atlantic was 25C roughly 2500 years ago on the surface (http://www.friendsofscience.org/assets/documents/FOS%20Essay/seasurface.GIF), add in that salt levels should stay roughly equal as the ice caps are frozen seawater. So that's 103C without factoring an increase in salt concentration due to evaporation.
I know fine well someone will sit and pull this apart and I couldn't care less, it's your time to waste. Hope at least someone will sit there and see sense.
Now can we ditch short term renewable energy and look at an actual solution, too much to ask?
