scientists have been
studying this for some time. Perhaps it can never be proven or disproven.
Fact of the matter is, we have droughts too long in some parts, and flooding in others. I guess we always have.
We also have nearly 8 billion of us now. All expelling warm air, a trifle example, but how many internal combustion engines exhale pollution. Fewer rain forest trees, concrete and asphalt roads which hold or reflect heat back up we did not have a century ago.
Glass skyscrapers do also. One in London melts the mirrors on cars.
There are those who still do not believe the ozone layer was even damaged by fluorocarbons, but that was proven. Then we have more skin cancer today, which began in Australia, below the ozone depletion ring.
China has also recognized the need to care for mother earth, as they showed at the last climate change summit. China is responsible for a lot of population growth.
I've seen solar generating arrays in places which once had big industry.
They are closer to large educational institutions like Carnegie Mellon, and Pitt universities.
The fact is that energy is a finite commodity, so we will use up what we have in all sources, while adding to new ones, regardless of what any politician thinks or says. They do not know everything. Scholars become experts through study.
California only has one nuclear generating plant still in operation. Do the math.
Lake Meade's water level has dropped to the point that lower intake points for the Hoover dam hydro plant had to be retrofitted.
Dire need often advances technology while profitability may not.
Holland has been pumping water away with wind for two centuries.
