NASA currently has more than a dozen Earth science spacecraft and instruments in orbit studying the oceans, land, and atmosphere. With these tools they measure several key climate change indicators like carbon dioxide concentration, global surface temperature, Arctic sea ice, land ice, and sea levels.

2009: Second Warmest Year on Record; End of Warmest Decade
2009 was tied for the second warmest year in the modern record, a new NASA analysis of global surface temperature shows. The analysis, conducted by the Goddard Institute for Space Studies (GISS) in New York City, also shows that in the Southern Hemisphere, 2009 was the warmest year since modern records began in 1880.
Although 2008 was the coolest year of the decade — due to strong cooling of the tropical Pacific Ocean — 2009 saw a return to near-record global temperatures. The past year was only a fraction of a degree cooler than 2005, the warmest year on record, and tied with a cluster of other years –1998, 2002, 2003, 2006 and 2007 1998 and 2007 — as the second warmest year since recordkeeping began.
