Global Warming Around the World

Skyfarming

A Columbia professor believes that converting skyscrapers into crop farms could help reduce global warming and make New York cleaner. It’s a vision straight out of Futurama—but here’s how it might work. It would be tough and expensive to pull off, which might negate being able to do this. Just think of the cost of square footage in Manhattan and the cost of trucking in veggies. It's a great article on thinking outside the box.

10,000 kW Electrical Power Generation in Your Backyard

Want to get off the grid? the Electric grid that is. The QR5, from U.K.-based Quietrevolution, is a residential-scale wind turbine that generates enough electricity to power a standard U.S. home or a small office. It also looks like a piece of wind-powered sculpture. Unlike the shape of a conventional windmill propeller, it’s a Vertical-axis wind turbine.

The World's Most Polluted City

In the most polluted city on earth, the smog is so thick that it seems to consume its source. Iron foundries, smelting plants and cement factories loom out of the haze then disappear once more as you drive along Linfen's roads. The outlines of smoke stacks blur in the filthy mist. No sooner are the plumes of carbon and sulphur belched out than the chimneys are swallowed up again.

California being warmed by urbanization, not Global Warming

Average temperatures across California rose slightly from 1950 to 2000, with the greatest warming coming in the state's big cities and mostly caused by urbanization -- not greenhouse gases -- authors of a study said.

New, unknown climate zones seen by 2100

Global warming could re-make the world's climate zones by 2100, with some polar and mountain climates disappearing altogether and formerly unknown ones emerging in the tropics, scientists said on Monday. And when climate zones vanish, the animals and plants that live in them will be at greater risk of extinction.
