The next time a ball game gets rained out during the September stretch run, you can curse the momentary worthlessness of those tickets in your pocket. Or you can wonder why it got rained out — and ask yourself why practice had to be called off last summer on a day when there wasn’t a cloud in the sky; and why that Gulf Coast wharf where you used to reel in mackerel and flounder no longer exists; and why it’s been more than one winter since you pulled those titanium skis out of the garage.
Global warming is not coming; it is here. Greenhouse gases — most notably carbon dioxide produced by burning coal, oil and gas — are trapping solar heat that once escaped from the Earth’s atmosphere. As temperatures around the globe increase, oceans are warming, fields are drying up, snow is melting, more rain is falling, and sea levels are rising.
