Well I look at it this way if the universe wants us gone then we're toast. Changing our ways ain't going to help. Look at the dinosaurs. They didn't drive cars they stayed within the bounds of nature and something wiped them out. If you're think having an environmental conscious is going to stop a meteor...
And besides to think that carbon emissions that have been going on for three hundred or so years are going to have a significant impact on the earth in one hundred thousand years is still a stretch. Especially now that humans are becoming enviro-savvy. It's entirely possible we can fix our problem. For what it's worth in the grand scheme of things.
VERY debatable. Yeah if a local star decides to give off a massive cosmic ray burst and burns off our atmosphere, not a hella lot we can do about it, and it's certainly not going to be our fault.
The problem with the arguments for and against global warming is that we're speaking in degrees: How much of an effect are we truly having? In my view this is incredibly ignorant and foolish...let's indulge and do something hypothetical for a moment. Suppose there are natural forces at work; some of these long term global cycles that we know have occurred in the past. Suppose these natural causes are 90% to blame. OK fine, Earth is just doing what it's been doing for eons.
However, even though the matter of degrees of guilt is a very
contested argument, the international scientific community is nearly unanimous on the belief that we're absolutely responsible to some degree.
So, going to back to my original hypothetical argument, what if our 10% contribution is the 10% that helps push the climate over the edge? At the least, what if it's enough to speed up something that's naturally occurring, enough to speed it up to a pace that the global biosphere can't handle?
I'm sorry, but I can't see any rational counter-argument here. Are we willing to gamble that we're not responsible at all, and just keep on going as we are? Because if we do, we're betting the entire pot: This is a potentially an all-or-nothing roll of the roulette wheel. An argument of degrees is missing the point.
Arguing if we started it or are just helping it is pointless and insignificant: It is occurring, and one does not sit inside a burning house and watching it burn while they argue the best way to help put it out.
