Climate change still happening

According to NASA, 2009 was the second warmest year in modern times.

Climate scientists agree that rising levels of carbon dioxide and other greenhouse gases trap incoming heat near the surface of the Earth and are the key factors causing the rise in temperatures since 1880, but these gases are not the only factors that can impact global temperatures.

Three others key factors -- including changes in the sun’s irradiance, oscillations of sea surface temperature in the tropics, and changes in aerosol levels -- can also cause slight increases or decreases in the planet's temperature. Overall, the evidence suggests that these effects are not enough to account for the global warming observed since 1880.
It's frustrating that the media still entertains the notion of a global scientific climate change conspiracy. This doesn't do anyone any good. But I guess it makes sense, considering the media also promoted the idea that smoking didn't cause cancer back in the day. More doctors smoke camels, right?
