You guys should all join the University of Shonky, I sure they would accept you in.
Most of the stuff you are talking about is short term, now excluding an ELE, man is the only animal actually increasing the background CO2 in the atmosphere.
Nature does its own job, with ice ages and global warming ending ice ages over epoch's of time, but we are trying very hard to do it in the space of hundreds of years, not millions of years.
BTW, whatever weather you are currently used to, you can be sure it will be changing too, if not already. Also, where it was generally cold, it might get a lot warmer and where is was generally warm, it might get a lot cooler. If you live in a temperate zone (not too much of one or the other), well you will need five things, 1) a home air conditioner, 2) a home heater, 3) winter clothing, 4) a bomb shelter (well cellar would probably do) and 5) lots of sun screen.
