Weather and Climate 

It rained this morning in North San Diego County. Not a big deal, although after several very dry years the rain is welcome. But looking in today's San Diego Union-Tribune, the forecast was for "Areas of low clouds along the coast in the morning; otherwise, mostly sunny today." No mention of rain. Now, I don't know when that forecast was compiled, but it must certainly have been within the last 24 hours, and if there were any greater than minimal probability of rain, I would have expected to see it in the forecast.

My point is that sophisticated and well-equipped meteorologists were not able to accurately predict the weather 24 hours in advance. It seems to me that day-to-day weather prediction is, or at least should be, a much better developed science than global climate prediction. The variables are better understood, the data are more comprehensive, more available and more accurate, and the system is much less complex in the former instance than in the latter.

For the life of me, I have great difficulty understanding why we should place much stock in the predictions of global warming alarmists who want us to spend billions, if not trillions of dollars "fixing" the supposedly anthropogenic damage to our climate, based on computer models that purport to be able to predict climate one or two centuries in the future, when we can't even get tomorrow's forecast right.
