Scientists Eat Crow on Geoengineering Test. Me, Too

Scientists Eat Crow on Geoengineering Test. Me, Too

Scientists (presumably including Keith) were outraged that such a thing could happen. It’s not that they have anything against algae, but rather that the project was a type of geoengineering — a suite of anti-climate-change strategies that are highly controversial because they have the potential for triggering significant unintended consequences.… Read More

Geoengineering: Risky to Do, Riskier to Ignore

Geoengineering: Risky to Do, Riskier to Ignore

I’ve got to admit I’m not the world’s biggest fan of geoengineering, and I’ve said so quite publicly. The idea is that if we fail to cut back greenhouse gas emissions and the planet’s temperature soars to potentially dangerous levels, we’ll have to do something. I’ve got to admit I’m not the world’s biggest fan of geoengineering, and I’ve said so … Read More

The Little Ice Age Explained?

The Little Ice Age Explained?

Nobody knows for sure why the planet cooled dramatically starting 700-ish years ago. But a newly published paper argues that the culprit was a series of massive volcanic eruptions that rocked the tropics starting in 1275 A.D and threw tons of sun-blocking particles into the stratosphere … Read More

New Breakthrough in Solar? Maybe. Possibly. Or Not.

New studies have found a way to double the efficiency of solar cells while cutting the cost. Is this finally the solution we have been looking for? … Read More

The Easy Fix That Isn’t: White Roofs May Increase Global Warming

White roofs might keep your house a bit cooler, but it would be at the expense of heating the planet, says a new study. … Read More

Brighten the Water: Proceed with Caution

By increasing the number of microscopic bubbles at the ocean’s surface, Seitz says, the water’s reflectivity will increase. More light will be scattered away and the planet will be kept cooler.… Read More

Montana Workshop Examines Ethics of Solar Radiation Management

Even if temporarily geoengineering the climate to create a bridge to more acceptable levels of atmospheric carbon proved technically possible, there might still be legal, political, and ethical reasons not to do it… Read More
