How did we get out of the last Ice Age?
Algore held a concert and ROCKED US OUT!
If colder oceans suck up CO2, warmer oceans give off CO2, AND CO2 drives the climate (all assumed to be true), then why doesn’t the climate just go to one extreme and stay there?
A cold planet could not conceivably get back its CO2, and a warm planet could not get rid of it. It would force the climate to one extreme or the other.
So what gives?
SUVs.
Archaeologists have unearthed remains of Cro-Magnon Man, and discovered that they had a system of carbon credit tracking used at their fire pits. No word though on whether the Neanderthals used carbon credits in conjunction with their SUVs and other vehicles. Further study is needed at other archaeological digs.
I like that closing sentence -- "future decision-making could be made based on scientific data and not on political expediency". I wouldn't count on it, but that would be great.Caves reveal clues to UK weatherAt Pooles Cavern in Derbyshire, it was discovered that the stalagmites grow faster in the winter months when it rains more. Alan Walker, who guides visitors through the caves, says the changes in rainfall are recorded in the stalactites and stalagmites like the growth rings in trees. Stalagmites from a number of caves have now been analysed by Dr Andy Baker at Newcastle University. After splitting and polishing the rock, he can measure its growth precisely and has built up a precipitation history going back thousands of years. His study suggests this autumn's rainfall is not at all unusual when looked at over such a timescale but is well within historic variations. He believes politicians find it expedient to blame a man-made change in our weather rather than addressing the complex scientific picture.
