Detroit Illustrates Global Warming fears Unjustified

Yesterday, Metro Detroit was hit by a series of showers and thundershowers. None were severe, and there was no damage other than a bit of localized and minor flooding. It was not a particularly newsworthy event. Detroit experienced little more than a normal late summer day, except for one thing.

There wasn't supposed to be thundershowers. It was supposed to be a pleasant, sunny day. At least, that was the forecast as of Sunday, a mere 48 hours earlier.

That still does not qualify as as news. Or does it? Seen against the bigger picture, it may well be of note. When the specter of global warming is considered, where we are expected to believe in things which will not be for 50 to 100 years, or well into the future (Orwell?), there is something to give one thought. Seeing as weather predictions are based on computer models and that global warming forecasts are based on such things too, how can we trust the cry of global warming? If our presumed experts can't get a 48 hour weather projection right, how can we trust them to be correct over things they assure us will happen over an entire century?

To be sure, we'll be told that anomalies will occur. Certainly an anomaly of some sort happened between this past Sunday and yesterday afternoon's inclement weather which changed things significantly. Things do happen; no one disputes that. Yet it really only adds to the trouble. If what surely were minor glitches happened which changed our predicted weather in just two days so considerably, how many glitches might happen over one hundred years which would alter the likelihood of global warming as currently predicted? Indeed, how can we trust that science can accurately predict what will happen over the whole world over many decades when it can't necessarily predict what will happen in one small part of that same world over two days?

To be fair, our weather forecasts are generally accurate. They call for a series of sunny and warm days now in Detroit, and we will almost surely get them. Still, it seems that the inaccuracy of yesterday's forecast ought to be a serving of humble pie, not merely for our local weathercasters, but for their friends higher up the scientific food chain as well. If we can't be right in the short term when being right ought to be relatively easy, we must then predict the far future with greater reserve, a and quiet calm.
