On: The Earth is getting greener

[lebean]

As long as the top billion lets the bottom billion develop like they have and use cheap energy, humans will continue to be fine. Good, even.

The bottom billion lives on $2 a day. It doesn't matter how cheap energy is, they can't afford it.

OTOH your comment does apply to the second billion. There's no energy cheaper than solar power, and solar powered air conditioning is a great supply/demand match.
