Abstract. We update the Goddard Institute for Space Studies (GISS) analysis of global surface temperature change. --- We conclude that global temperature continued to rise rapidly in the past decade, despite large year-to-year fluctuations associated with the El Nino-La Nina cycle of tropical ocean temperature.

"Climate trends can be clearly seen if we take the 60-month (five year) and 132-month (11 year) running means." The five year mean minimizes El Niņo variability, while the 11-year mean minimizes solar-cycle variability. Solomon could not be immediately reached late Saturday night.

The warming trend was visible, Hansen said in an email, even in this year's bitter Northern Hemisphere winter, which blanketed Britain and the East Coast in snow and had some Republicans claiming that the Snowmageddon proved global warming as a hoax.

Winter weather will always be highly variable, Hansen said. Areas cold enough to have snow can expect more from a carbon-rich atmosphere containing more water vapor. But while the Arctic Oscillation over the past three months was remarkable, the cold temperatures were relatively benign compared to the late 1970s.

Supporters say that filtering of such "noise" makes long-term temperature trends visible. It also allows the NASA team to predict that 2010 will emerge as the hottest year on record. At first blush, it doesn't seem likely: The sun is near the bottom of deepest solar minimum in a century; this year's El Niņo, while strong, is nowhere near as powerful as the 1998 cycle that drove temperatures higher across much of the globe. But the trend, Hansen and colleagues conclude, is up. "This new record temperature will be particularly meaningful," they wrote, "because it occurs when the recent minimum of solar irradiance is having its maximum cooling effect."

Just to reiterate: Climate change is real, Global Warming is real, Global Cooling is false.

We need to continue our every effort to protect the environment and cut down our carbon footprint.
