Geoengineering schemes range from increasing the amount of sulfur dioxide in the atmosphere to cool things down to covering polar and glacial ice with panels to slow melting to creating artificial trees to sequester carbon. But what’s wrong with just planting more real trees?

The average American could not name the last 10 presidents if you put a gun to his head. So why do we care what they think about a complex problem like global warming. Well, because the average legislator is no smarter than the citizens he or she represents, but they are smart enough to know which way the political wind blows.

When President Barack Obama was elected, all things seemed possible. Now . . . not so much.

The world is stretched thin. We can’t take too many Haiti’s without the whole system collapsing. As bad as that ounce of prevention to forestall the worst effects of climate change may look right now, it will be a bargain at twice the price if it turns out we can’t afford the pound of cure.

Dr. Betsy Dresser in New Orleans, is taking DNA from endangered or extinct species and preserving it in liquid nitrogen.
