    A paper came out in 2009 suggesting that current co2 levels are higher now than at least 3 million years old, and more likely 15 million years.

    It is quite possible that a considerable amount of the increased carbon dioxide content of earth’s atmosphere since 1800 has been the warming of the seas with resultant expulsion of the CO2. This would coincide with the warming since the “Little Ice Age” of the late 17th/early 18th centuries. Carbon dioxide is less soluble in warmer water than in colder.

    The question of climate change has been answered for decades, yet we continue to ignore it or deny its existence. In two presidential debates it has not been mentioned once.

    Monday is the last chance, and if it is mentioned, I’ve got an ice berg I’d like to see you…

    A possible reason for the lack (now including Monday night’s) of mention of global warming/climate change/climate disruption/whatever’s next in the debates is that it is not the scientific juggernaut that it’s touted to be. Back in the mid-’80′s many of my colleagues taunted me for not having subscribed to the ’70′s cooling scare despite the record-shattering cold and snow of the 1976-1985 era. I did not believe the cooling for basically the same reason I do not embrace the warming scare. Look up Edward Walter Maunder, please!
