This is a speech I delivered on Earth Day, April 20, 2008, at the Unitarian-Universalist First Church in Jamaica Plain, Mass. A software glitch prevented its publication on that day, but I believe it's still worth sharing.
As Kurt Vonnegut once said, "I wish I could bring light ... but there is no light. Everything is going to become unimaginably worse. If I lied to you about that, you would sense that I'd lied to you, and that would be another cause for gloom, and we have enough causes already."
It is true that there are fewer bald-faced lies being told about the state of the earth -- even our president now admits that climate change is, well, shucks, kind of a problem -- but fewer lies does not mean that there is more truth.
Jim Hansen, the world's foremost climate scientist, is circulating a draft paper arguing that the climate "tipping point" must be reset at 350 ppm of atmospheric carbon, a point we passed two years ago.
If we do not immediately return below that level, Greenland and Antarctic ice shelves will collapse, with a catastrophic rise in sea levels. From the study of ancient ice cores and sea sediment, we now know that sea level change is episodic and quick ... measured in feet per decade, rather than inches per century.
Neither civilization nor global ecosystems can adapt to change this rapid.
Hansen sketches a solution of appropriate scale: immediate halt to burning coal; crash Marshall program to replace it with renewables; limit oil and gas use to known, economically viable reserves; full-scale reforestation and adoption of carbon-storing agricultural practices.
Nothing that we are doing, nor even seriously contemplating, comes anywhere near such massive a transformation, yet every actor on the political stage -- including major environmental organizations, "green" corporations, and presidential candidates of both major parties -- downplay the terrible realities and trumpet small-scale solutions wrapped in upbeat rhetoric.
We are racing toward the end of the world and have no plan of escape, but it is considered impolite to acknowledge that fact in public.
