Basic answer?
It's too late- we are screwed.
Real answer? Get the human population down to about 3 billion and live with a lot of freedom and prosperity. Continue down the same path and look at rationed water, cramped living quarters, lower quality food. And when we do have something bad, we'll have a tremendous die off.
Look- wind power has now been shown to reduce the winds (and affect the climate). And seriously... DUH? You are extracting huge amounts of energy from the wind- it's going to affect the winds.
Dump huge amounts of heat into the environment (in this case) is just another case of an organization externalizing their costs on the rest of society.
That heat is going to have an effect. There will be a cost. But the company dumping the heat is getting the benefit for "FREE".
Don't sell it as "free" and I won't bitch.
