Conspiracy Theories Fuel Climate Change Denial and Chemtrail Beliefs – September 5, 2013

We don’t have time for a wacky distraction and, in the case of climate change denial, a barrier to addressing an urgent, critical problem

I recently wrote about geoengineering as a strategy to deal with climate change and carbon dioxide emissions. That drew comments from people who confuse this scientific process with the unscientific theory of “chemtrails.” Some also claimed the column supported geoengineering, which it didn’t.

Dumping Waste into the Ground Is a Shaky Solution – July 6, 2012

Little is Known About Leaks from the 680,000 Waste and Injection Sites in the US

What can we do with wastes from our industrial pursuits—from fossil fuel extraction, agriculture, chemical and pharmaceutical manufacturing? We’ve been spewing lots of it into the air, but that isn’t a good plan. Carbon dioxide, ozone, mercury and other emissions harm human health and contribute to global warming and holes in the ozone layer. We’ve dumped it into the oceans. But that compromises marine life that billions of people rely on for food.
