This is the message that I've got from last evening Perimeter Institute lecture From Here to Eternity: Global Warming in Geologic Time
, presented by David Archer. Catastrophic climate changes
will happen if the world doesn't change its pollution patterns. The solution is the use of alternative sources of energy like solar or wind energy. I learned also about a kind of science fiction alternative of having solar cells on the moon and beam that energy to the Earth as microwaves.
