Upper ocean heat content has increased significantly over the past two decades. An estimated 70 percent of the excess heat has accumulated in the top 2,000 feet of the ocean, and the rest has flowed into deeper ocean layers.

2013 continued a trend of water vapor in the surface atmosphere increasing over land and ocean relative to the 1970s, while the atmosphere over land becomes less saturated. 

In 2013, global average sea level was 1.5 inches above the 1993-2010 average, which is the highest yearly average in the satellite record (1993-present). Overall, sea level continues to rise at a rate of one-eighth of an inch per year.

Climate change is a global phenomenon, affecting weather events around the world.
