Over the next two years, a team of scientists will try to inject carbon dioxide--charged water into the basalt beneath the ground through boreholes drilled by a nearby geothermal energy plant. The CO2 will, in theory, react with the porous rock and form a stable mineral that could remain in the rock for millions of years. If they're right, Iceland could not only render itself carbon neutral but also give the world a means of protection from the effects of CO2 emissions until they can be reduced...
Even the most effective individual action, however, is not enough. Cleaning up the wreckage left by our 250-year industrial bacchanal will require fundamental changes in a society hooked on its fossil fuels. Beneath the grass-roots action, larger tectonic plates are shifting. Science is attacking the problem more aggressively than ever. So is industry. So are architects and lawmakers and urban planners. The world is awakened to the problem in a way it never has been before. Says Carol Browner, onetime administrator of the EPA: "It's a sea change from where we were on this issue." Here...
...Department of Energy is funding seven research partnerships to test sequestration technologies. This summer, one of those projects will inject a modest 2,000 metric tons of CO2 into the sandstone subsurface beneath a spread of tomato fields near Thornton, Calif., where it would stay, in effect, forever...
...Christian border village of Alma Shaab. With the coordinates logged into a GPS device, Ghaith and I walked carefully along a track winding through blossom-scented orange orchards at the bottom of a steep-sided brush-covered valley. Snakes and lizards basking in the hot sun slithered from beneath our feet. But we kept our eyes open for cluster bombs, which have since August caused 224 casualties among Lebanese civilians and mine-clearing crews, which had used red spray paint to mark the location of each bomblet...
...almost missed the manhole cover beneath its layer of dirt, dead leaves and twigs. Using metal footholds, I climbed down into the gloom below and saw with some relief that the tunnel at the bottom was larger than we had feared. We would have to crouch, but not crawl. It was still a tight squeeze as we inched cautiously along the dank silent passageway, which ran for about 20 feet before turning left and descending in a gradual slant. The rock sides of the tunnel were lined with a mesh of steel bars and girders. Huge brown spiders clinging...
