so you think we should prepare for total annihilation from a giant platinum or ice space conglomerate?
now climate change is beginning to sound less silly in juxtaposition! lol
its a matter of allowing mankind to spew more co2 or not. you don't want dirty liberal hands on your laws to restrict pollution. but you don't want economic downturns either? addressing climate change in the short term may be costly but over the long term it will save money (likely preventing serious economic downturn) as well as certain species for extinction.
i guess these things are not worth short term money. i don't buy your logic and you won't either in 3 decades.
The world is a system that has survived quite well for the vast majority of its life. Warmth has never been a problem. Cold has. If you wish to see a time when the planet is suffering just look at the paleo record, cold kills and warmth doesn't. The last time the planet was really warm (during the PETM) the flora and fauna bloomed. Most of the major species of mammals were evolved during the PETM.
Now look at the history of asteroid strikes. ONE of them hit (that we know of) and almost eliminated life on this planet. Mankind is the first species on this planet capable of doing something about that.
And you fools would rather whistle Dixie.
This was a small one.
