...artificially changing cloud cover could disrupt global precipitation patterns, a risk that climate scientists Susan Solomon and Gabriele Hegerl raised in a recent article in Science. They found a global drop in precipitation levels after the eruption at Mt. Pinatubo, and an increase in droughts. A cool but dry planet wouldn't be an upgrade from where we are now. "Climate change impacts are driven not only by temperature changes, but also by change in other aspects of the climate system, such as precipitation and climate extremes," they write...
...pump billions of tons of carbon dioxide into the atmosphere, we're doing more than warming the planet and scrambling the climate. We're also conducting what climatologist James Hansen has called a "vast uncontrolled experiment." In effect, we're on our way to engineering a world very different from the one we were handed. Belatedly, we're trying to turn off the carbon spigot, hoping that by incrementally reducing the emissions we've spent a couple of centuries pouring into the air we can stop the climate slide before it's too late...
...small but growing number of researchers are beginning to say yes. If we geoengineered the earth into a mess with our uncontrolled appetite for fossil fuels, maybe we have to geoengineer our way out of it - in effect, directly cooling the planet via a controlled experiment to counteract our uncontrolled one. Indeed, according to a just-published paper for the Copenhagen Consensus on Climate - a think tank studying inexpensive solutions to climate change - geoengineering might not only be a good way to bring rising temperatures under short-term control while we wait for the longer-term fix of cutting carbon...
...Without a little bit of it, the earth would be a cold, dead place, with an average temperature as low as -0.4°F. Unfortunately, by adding CO2 and other greenhouse gases to the atmosphere, we have, in a sense, thrown another quilt on the planet when we were perfectly comfortable to begin with.

...struggling with apartheid," recalls retired Archbishop Desmond Tutu, the moral force of South Africa's political change, "we spoke of People Power. You had to be with the people to make change happen." At the dawn of a new century, his words may feel stunningly obvious. Yet to a planet conditioned by colonialism or Confucianism or tyranny to think that the people's obligation is to follow, not lead, Aquino's inspiration was truly transformative...
