The most likely explanation for the lack of significant warming at the Earth’s surface in the past decade or so is that natural climate cycles caused shifts in ocean circulation patterns that moved some excess heat into the deep ocean.

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.

El Niño and La Niña conditions occur when abnormally warm or cool waters accumulate in tropical latitudes of the central and eastern Pacific Ocean. The Oceanic Nino Index is the tool NOAA scienitsts use to watch for these temperature changes.

An open-source suite of tools developed specifically for farmers and ranchers in the southeastern U.S. Tools available can help growers plan for certain types of crop disease, crop yields, climate and drought risks, growing degree days, greenhouse gas emissions, and water usage.

The Southern Plains should prepare for continued drier and warmer than average weather, while the Pacific Northwest is likely to be colder and wetter than average from December through February, ac

La Niña, which contributed to extreme weather around the globe during the first half of 2011, has re-emerged in the tropical Pacific Ocean and is forecast to gradually strengthen and continue into

According to NOAA's Climate Prediction Center, La Nina is gone. This period of colder-than-average sea surface temperatures in the eastern equatorial Pacific Ocean has passed.
