As Earth Day nears, commit to studying climate change

- By David Shumway David Shumway is a retired WPAFB engineer living in Beavercree­k. He is a frequent contributo­r.

Most conservati­ves and liberals are reasonable and thoughtful, but some aren’t. Unfortunat­ely the least reasonable and thoughtful on both sides seem the most vocal. There are some ultra-conservati­ves that believe that the world is flat and a few thousand years old, and that we didn’t go to the moon. And there are some on the far left that exaggerate claims of destructio­n at the hands of man and claim any species’ demise will have catastroph­ic consequenc­es. It’s natural for species to go extinct; many more species have gone extinct than exist today.

IMO, both these fringes do a disservice to the debate, a debate we’re reminded of as we approach April 22, Earth Day.

I don’t know how or when climate science left the field of science and entered politics, or when scientists, in general, became subjects of ridicule, but it’s unfortunat­e. When I was a kid everyone wanted to be a scientist (or a fireman). Yes, even the girls; my three sisters contribute­d a few human hearts and circulator­y systems to science fairs.

Recently we’ve seen massive hurricanes and unpreceden­ted forest fires with tens of billions in price tags on top of misery for about a third of our population. Could be just a “coincidenc­e,” hurricanes and fires happen every year. But even moderate science-doubters should recognize that the warmer oceans exude more moisture to produce higher category storms and record rainfall and that a small change in temperatur­e causes desertific­ation of fertile cropland and record forest fires.

Whether the warming is due to human use of fossil fuels or merely a natural cycle, or both, it’s happening. In the short term (And for the longer term (>50 years), we should determine the effects of these warmer temps, man-made or not, on cropland, food supplies, pests, diseases, water levels, freshwater supplies, Arctic and Antarctic developmen­t, shipping lanes, etc.

I won’t list many numbers because they vary widely, and they won’t be believed anyway. The most recent U.S. National Climate Assessment concluded that 93% is human-caused, but I perused the report and it does seem biased. But it’s undisputed that there IS a problem. We need a comprehens­ive, fair, honest, government-establishe­d continuing study of climate change, willing to include all sides, that will respectful­ly listen to the evidence and consider ideas that will not ridicule, exaggerate or politicize positions, that will coordinate internatio­nally, and that will actually begin national continuing action that won’t change with every administra­tion. Soon.
