The IPCC (yes, I know) has stated that atmospheric CO2 maintains one sixth of the energy delivered by the sun to the earth. Subsequently, more CO2 means more energy capture. The difficult part of the equation is that the earth's atmosphere has had up to 1440 ppm of CO2 and it didn't become an arid wasteland. Atmospheric CO2 is currently 387 on its way 450.
If the planet has been 10 degrees warmer and seas have been 8m higher predating industrialisation, why can't this round of global warming be a natural event?
If the polar ice caps are melting and becoming warmer does this mean the tropical zone and the sub-tropical zone will expand to cover more of the world, and if it does, won't that mean more of the planet becomes arable, not less?
I don't get it?
Can someone with half an idea (i.e. not a frothing, end of the world greenie) explain any of that to me?
I think the US economy ought to be the priority for the record.
