An even shorter version is: It is getting warmer; CO2 is a greenhouse gas and so an increase in it will drive warming (logarithmically without feedbacks); we are taking many gigatons of C out of the earth and dumping it into the biosphere as CO2; the increase in CO2 and the change of isotopes in the C are consistent with the source being the fossil fuels we are burning.

(As a quick rule of thumb, with today's technology each TW releases about half a gigaton of carbon into the atmosphere each year.)

McKibben writes, «Scientists estimate that humans can pour roughly 565 more gigatons of carbon dioxide into the atmosphere by midcentury and still have some reasonable hope of staying below two degrees.»

Richard # 63, for that weather to last long enough to become a climatological forcing (it would have to take gigatons of carbon out of one system and dump it into another) it would either have to be a catastrophic event (clathrates suddenly erupting, supervolcano erupting, etc) or long lasting (in which case open to climatological statistics rather than weather chaotics).

And that's against the background where nobody in their right mind argues that [we haven't] already dumped several hundred gigatons of carbon into the atmosphere.
