At some point in our adolescence most of us came to the shocking realization that our parents weren’t perfect, that they made errors in judgment. But it took some time for us to figure this out, to sort out truth from fiction. Such is the case with global warming, with learned (and not so learned) opinions on both sides of the issue. This a “hot button” issue, what with some scientists telling us that we’re near the tipping point, that unless something is done in the next ten years or perhaps less, global warming will have progressed past man’s ability to “solve” the problem.
On the other side of the issue are what global warming proponents call “deniers”, who say that changes in global temperatures aren’t nearly as much due to carbon dioxide and other greenhouse gases as to natural phenomena such as solar radiation, El Nino and La Nina. Among these detractors (and most definitely in the minority among scientists) is Drew Lerner, an agricultural meteorologist who predicts that the earth is actually starting a cooling cycle this year that should be evident in about five years. Talk like this really gets under the skin of folks like Al Gore, who’s claiming that global warming will cause sea water levels to rise by 20 feet in the next 20 years, putting much of the U.S. coastline under water. Of course, this is the guy who claimed to invent the Internet…
I don’t know whether we’re getting hotter or colder, how fast, or the reasons for it. Most scientists with knowledge on the subject say we’re warming, but this isn’t an election. However,whether or not fossil fuels and the carbon cycle are having an effect on global temperatures, what’s undeniable is that our supply of petroleum is finite and some day our global oil tank will run dry. This makes energy conservation, on a global, national and local scale, a responsible course of action. And with current energy costs, it’s simply good business. This is something on which both global warming proponents and deniers can agree.
