Global warming trumps gay bashing
[Rick] Warren's concern about global warming trumps his hateful rhetoric on gays?
BBC NEWS | Nasa set to launch 'CO2 hunter'
The US space agency is set to launch a satellite that can map in detail where carbon dioxide is in the atmosphere.

Nasa's Orbiting Carbon Observatory (OCO) will pinpoint the key locations on the Earth's surface where CO2 is being emitted and absorbed.

CO2 from human activities is thought to be driving climate changes, but important facts about its movement through the atmosphere remain elusive.
Did Early Global Warming Divert A New Glacial Age?
ScienceDaily (Dec. 18, 2008) — The common wisdom is that the invention of the steam engine and the advent of the coal-fueled industrial age marked the beginning of human influence on global climate.

But gathering physical evidence, backed by powerful simulations on the world's most advanced computer climate models, is reshaping that view and lending strong support to the radical idea that human-induced climate change began not 200 years ago, but thousands of years ago with the onset of large-scale agriculture in Asia and extensive deforestation in Europe.

What's more, according to the same computer simulations, the cumulative effect of thousands of years of human influence on climate is preventing the world from entering a new glacial age, altering a clockwork rhythm of periodic cooling of the planet that extends back more than a million years.
