From record-low Arctic sea ice to the highest global sea level of the modern record, the 2012 State of the Climate report provides a complete rundown on the state of Earth's climate and how it is changing.

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: i

Tampa Bay Water provides safe, potable drinking water to 2.3 million people in the Tampa Bay region.  But future availability of surface water can be hard to predict, and drought is a recurring challenge there.  The water utility managers are increasingly using seasonal climate forecasts to track climate variability, which helps them better plan their water supply and reduce their vulnerability to seasonal climate impacts.

NOAA’s Climate Prediction Center (CPC) has issued its 2013 Atlantic hurricane seasonal outlook. In this video, Gerry Bell, a NOAA CPC meteorologist, explains that as of May 23, 2013, the outlook favors an above-normal Atlantic hurricane season from June 1 through November 30.

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.

Deke Arndt, Chief of the Climate Monitoring Branch, at the National Climatic Data Center talks about the influence of La Niña on the 2011 global average temperature.
