Past episodes of climate change are a known fact, there's no disputing that, and human involvement in them was somewhere between miniscule and nil. What's happening to the climate now is mostly to do with CO2 levels in the atmosphere rising very quickly. We know how much carbon we're pumping into the atmosphere and where it's coming from, and we know how the greenhouse effect works. Human-induced global warming doesn't require your acceptance or belief to be true.
I find it simultaneously amusing and deeply concerning that some of the most vocal deniers of human-induced climate change come from North America, and North America during the last century and into this current century was one of the greatest contributors to increasing the levels of CO2 in the atmosphere. Having said that, on a per-capita basis Australians have been some of the worst contributors in recent times. Once again there are psychological factors at play for many Americans and Australians alike. It's easier to deny that we're the cause than taking responsibility, and to really meaningfully try to fix the problem we'd almost certainly have to dramatically hurt our industries and our lifestyles, with no guarantee that the up and coming major polluters like China and India will hold back at all.
Just finally, Howling Wilderness never explicitly states that the disrupted rainfall patterns over the US were permanent, or even long term. There's nothing stopping a GM having the rainfall patterns starting to normalize for the 2002 growing season.
