"What on Earth? Why Climate Change Skeptics Are Backing Geoengineering"

"Next month, a Silicon Valley engineer plans to head out on a snowmobile from Barrow, on the northern tip of Alaska, to sprinkle reflective sand on a frozen lake to try to stop it from melting.

It’s part of a journey that began in 2006, after Leslie Field watched the climate change documentary “An Inconvenient Truth” and felt like she’d been “hit by a big fat truck.” Now, she hopes to gather global support to cover more than 19,000 square miles of sea ice – an area about the size of Costa Rica – with a thin coating of tiny floating silica spheres, which she claims will help reduce the world’s rising temperatures.

The cost estimate? $1 billion a year."
