Check out this climate essay in The American Scholar by Robert Laughlin, a Nobel laureate in physics.
Here's a sample:
"Climate change, by contrast, is a matter of geologic time, something that the earth
routinely does on its own without asking anyone’s permission or
explaining itself. The earth doesn’t include the potentially
catastrophic effects on civilization in its planning. Far from being
responsible for damaging the earth’s climate, civilization might not be
able to forestall any of these terrible changes once the earth has
decided to make them. Were the earth determined to freeze Canada again,
for example, it’s difficult to imagine doing anything except selling
your real estate in Canada. If it decides to melt Greenland, it might be
best to unload your property in Bangladesh. The geologic record
suggests that climate ought not to concern us too much when we’re gazing
into the energy future, not because it’s unimportant, but because it’s
beyond our power to control."
