Not to divert from Gordon Sims’ question, but here’s another point I’ve never been clear on.
Who gets to determine what the optimum temperature or climate for the planet is, and how is that even determined in the first place? There are no constant conditions on our Earth so the climate in different areas is changing in different ways, all the time. Who is to say that some arbitrary temperature pattern is “normal” for the whole planet? I mean, if you just consider that one point, you see the whole theory falls apart. It’s not up to us to say, “Because I think we should always have perfect weather (California’s weather, probably), then when things are trending away from my ideal, it means there is a problem.”
The reality is, the only problem is people making money and getting tremendous power from scare tactics that have ZERO basis in reality.
Hey, if we’re determining the ideal climate, I want no tornadoes, no hurricanes, and about 30% humidity. I want cool falls, rainy springs, and some amount of pretty snow in the winter, but no ice storms please! Summers can be hot but not too hot, KWIM? And wind! I’ve always hated the wind, so no more really windy spells, just maybe up to a stiff breeze and no more than that.
My reading of the scientific debate is this:
The issue is not that the Earth or some particular region is not at its “correct” temperature and should not change, but concern that the Earth is in a phase (some think unprecedented since Homo sapiens has walked it) of unusually rapid climate change. When there is rapid change, there is widespread die-off of various species, especially the specialized ones, because adaptation via genetic selection does not happen quickly across the board.
While it is all fine and good to say that rapid changes are going to happen, some of the specialized populations are human. If climates change gradually, then agriculture and patterns of habitation and homebuilding can respond to the changes without nearly so much hardship as if the change is abrupt.
So here are the issues:
a) Are the climate changes being seen merely local minima or maxima or the return to a previous standard or are they beginning of a huge change to something very different that will be reached very quickly? For instance, some believe that the standard over 1500 years in the western states of the US is much drier than the last 150. If this is so, then it is prudent to start adjusting water usage right now. It is senseless to expand water-intensive crops in California if the water situation is only going to get worse. It also makes financial sense to invest in more expensive water management infrastructure if recent water shortages are going to be the rule instead of the exception, but a money-loser if rain patterns are going to go back to what they were. A guess needs to be made, and a lot is riding on it.
b) Is there a reason to believe that humans are contributing to the change, and how? This is a very complicated question, but also very important, obviously, because decisions on what technologies and infrastructure and living habits are either necessary or untenable could easily be made cheaply now but would be ineffective if they are delayed. So, again: the question is hard to answer because the situation is very complex, but the answer is too important to just throw hands up in the air and say, “Who knows?!”
That is climate change. There are other environmental issues, such as salinization of soils through irrigation of lands that are not flushed by seasonal heavy rains or the financial and international issues surrounding the discovery and recovery of various natural resources, that are on a different footing. I think you are on top of that distinction, though.
If you can take a few ice storms, I think you might like a sheltered portion of the Pacific Northwest, maybe Seattle. You might like Mt. Angel, Oregon, too, because they don’t get nearly the winds down there we do closer to Portland. (Portland gets some ripping east winds and ice storms, courtesy of the Columbia River Gorge.) Very nice orthodox Catholics down there in Mt. Angel, too, and a good seminary. You’d love the parish church, I think. Gothic architecture, great acoustics, beautiful:
