Since 1976, every year has been warmer than the long-term average, and 2012 continued the trend: the global surface temperature ranked among the top 10 warmest years on record.
Global average sea level in 2012 was 1.4 inches above the 1993-2010 average, which was the highest yearly average in the satellite record. Sea level has been rising over the past century, and the pace has increased in recent decades.
Earth's atmosphere includes billions and billions of gallons of evaporated water: in fact, water vapor is Earth's most abundant greenhouse gas.

As the whole ocean gets warmer, NOAA scientists must redefine what they consider “average” temperature in the central tropical Pacific, where they keep watch for El Niño and La Niña.
