Good News: Earth's Air is Less Polluted

Bad News: Global Warming Will Increase

Two studies from Science magazine indicate that reductions in the pollution of Earth's atmosphere in the past two decades have reduced "global dimming", meaning more sunlight reaches the ground.

Reductions in industrial emissions in many countries, along with the use of particulate filters for car exhausts and smoke stacks, seem to have reduced the amount of dirt in the atmosphere and made the sky more transparent.
Wow, that's good news! But wait a minute:
But the researchers say that more solar energy arriving on the ground will also make the surface warmer, and this may add to the problems of global warming. More sunlight will also have knock-on effects on cloud cover, winds, rainfall and air temperature that are difficult to predict.
So, even though we followed the environmentalists' advice and significantly reduced pollution, we're still screwed. I see, and so did renegade environmentalist Bjorn Lomborg
and author Michael Crichton.

It seems clear that there are those in the environmentalist movement who are using global warming as a profit source, and others who worship at its altar.
