It's not news to anyone who pays a heat bill.
the U.S. has cut CO2 emissions over the past 13 years faster than any other industrialized nation?
reckon that might be the reason why?
Wouldn't you have to first accept the theory that US CO2 emissions control global temperatures?
nope.
how many people have the first clue about the actual effect of CO2?
warning..math is hard.
More facts, plant life thrives in CO2 and most in warmth.
plants STARVE at CO2 levels not much below what it is now.
it plants die...everything else does too.
it's too bad because it would be nice if we could warm things up.
