The absolute arrogance of people who think that the earth's climate, which has been constantly in flux throughout Earth's history, should now remain constant because they're here gives me a headache.
Attention Algore, et al: the Earth's climate will change, and continue to change for as long as the planet continues to exist. Likewise, species will become extinct and new species will emerge. It was going on before we climbed out of the cave, went on while we developed cultures, outlasting all of them (thus far), and will continue into whatever comes next.
Get over yourselves.
This is the Pub. Leave common sense at the door.
