Bill Bradley Says:
“Let’s clear up some confusion.
The two PJM “Freeranger” politicians — Joe Lieberman and Arnold Schwarzenegger — both know that the greenhouse effect is real and both push policies to combat it.”
Let’s really clear up some confusion:
The “greenhouse” effect is not global warming, the “greenhouse” effect exists because the earth has an atmosphere. The earth has two sources of heat – the sun and the atmosphere. The earth is warmer than it would be otherwise without an atmosphere. Technically, the atmosphere doesn’t act exactly like a greenhouse.
The climate change questions are:
Is the current interglacial period the earth is in warmer than it would be otherwise because of human activity?
Will the next glaciation be delayed because of human activity?
Will this interglacial period become a post-glacial period because of human activity?
