	Ocean Acidification Impacts Coral Reefs The ocean is absorbing large amounts of carbon dioxide—a natural process. However, as carbon dioxide enters the ocean, it reacts with water to form acid. Subsequent chemical reactions that try to maintain a normal pH level in the ocean end up reducing the amount of calcium carbonate—a component in t (more...)
	African Droughts The Horn of Africa has been experiencing exceptional droughts over the last decade. Using data collected from the NOAA POES satellite, changes in the severity of the drought conditions in the Horn and around the world are shown.
	El Niño and La Niña The oceans warm and cool as the seasons change. However, sometimes there are periods of abnormally warm and cool sea surface temperatures. In the equatorial Pacific, these periods often result from phenomenon called El Niño and La Niña. This animation shows the warmer than average sea surface temperat (more...)
	Heating Up the Ocean Satellite measurements of sea surface temperatures (SST) are critical for weather forecasts, understanding ocean circulation, and even knowing where fish populations may be located. This animation shows daily SST trends over the last 25 years, along with analysis of how ocean temperatures have been chan (more...)
	The Melting North Pole The concentration and extent of sea ice in the Arctic has been on the decline since the mid-1990's. Data collected by the DMSP satellite's SSM/I sensor is shown here for 2007 - 2008. These two years had the lowest ice extents on record since satellite observations first began.
