Glacial Melt And Ocean Warming Drive Sea Level Upward

Show
The average sea level around the world has risen a total of 222 millimeters (mm) since 1875, which means an annual rate of 1.7 mm.1 (See Figure 1.) Yet at the end of this long period, from 1993 to 2009, the sea level rose 3.0 mm per year—a much faster rate.2 An estimated 30 percent of the sea level increase since 1993 is a result of warmer ocean temperatures that cause the water to expand (thermal expansion).3 Another 55 percent of the increase results from the melting of land-based ice, mainly from glaciers and the Greenland and Antarctic ice sheets.4 (Sea ice that melts does not contribute

First, The Great Pacific Garbage Patch; Now The Great Atlantic Patch

Show
Mike Melia, Associated PressSAN JUAN, PUERTO RICO – Researchers are warning of a new blight at sea: a swirl of confetti-like plastic debris stretching over a remote expanse of the Atlantic Ocean. The floating garbage — hard to spot from the surface and spun together by a vortex of currents — was documented by two groups of scientists who trawled the sea between scenic Bermuda and Portugal’s mid-Atlantic Azores islands.

European Water Mission Lifts Off

Show

A European satellite is set to provide major new insights into how water is cycled around the Earth. The Smos spacecraft will make the first global maps of the amount of moisture held in soils and of the quantity of salts dissolved in the oceans. The data will have wide uses but should improve weather forecasts and warnings of extreme events, such as floods. Miras will measure changes in the wetness of the land and in the salinity of seawater by observing variations in the natural ... ... Read more about European Water Mission Lifts Off

WE NEED LEGISLATION THAT WILL SAFEGUARD OUR OCEANS

Show

Earth’s atmosphere isn’t the only victim of burning fossil fuels. About a quarter of all carbon dioxide emissions are absorbed by the earth’s oceans, where they’re having an impact that’s just starting to be understood. Leading scientific experts believe that it’s possible to cut back on global warming pollution, improve the overall health and durability of our oceans, and prevent serious harm to our world—but only if action is taken quickly and decisively. ...
