Over Populated - Are We There Yet?

I watched NOVA on PBS last night, "Dimming The Sun". They described some of the scientific research that proves that airborne particles (and the cloud formations that they facilitate) significantly reduce the amount of sunlight that strikes the surface of the earth. This reduction in sunlight has a measurable cooling effect on the earth.

While this reduction in sun light and the cooling effect might seem to be a beneficial counter to global warming, it also causes problems. Scientists believe it may have contributed to some of the devastating droughts in Africa and, of course, air pollution is a serious health concern.

The most sobering observations were that global dimming has masked the effects of global warming and that as we continue to make progress decreasing air pollution, we will greatly increase the rate of global warming. The current models that attempt to project the rate of global warming do not take into account the full effects of global dimming. We may have much less time to bring global warming under control. Many decades less time. There is a point at which the effects of global warming begin to cascade and there will be nothing we can do to reverse it. Let me say it again, there is a point where reversing global warming will be completely out of our control. That time may be closer than we think.

It has taken decades to convince people that global warming is real. How long would it take to convince people we should stop trying to prevent air pollution until global warming is under control?

I'm sure there are people who will argue that global dimming is just as unreal as global warming, but they've been arguing against global warming for years and so far no good, hard evidence has appeared to suggest they are correct. Global warming is a big problem that will take massive and, probably, painful solutions.

One of the solutions to global warming should be population reduction. Reducing the world's population by itself will not reverse global warming fast enough, but it should be a another tool.

Doesn't common sense tell us that more people on the planet will only make our environmental problems worse? At some point there will be more people on earth than the planet can support. When that time comes we can reduce population several ways: nature can make drastic reductions (disease, famine, loss of habitat), governments can force family planning or we can make voluntary reductions. Since the first two have already occurred in some places, shouldn't we be proactive and start voluntary reductions?

By the way, if we don't bring global warming under control soon, population reduction will occur.
