A belated post for Earth Day

By drfrank

[...] from a planetary perspective, a quadrupling of atmospheric carbon lasting 10,000 years (for example) is little more than a passing blip. The fact of the matter is that, no matter how much greenhouse gas we pump into the atmosphere or how many toxins we dump into the soil and oceans, given enough time the Earth will recover.

But human civilization is far more fragile.
