Global Warming - What does it mean?

For those people who still cling to the hope that global warming is some liberal stunt and science has yet to prove that man has induced climate change, we have this news to share:

The world's coral reefs are in danger of dying in the next 20 years unless the world drastically cuts carbon emissions. The coral reefs are a a major part of the planets delicate eco-system, without, much ocean life will not survive.

FOR EVERY HUMAN, ANIMAL AND PLANT ON EARTH, A HEALTHY OCEAN IS A MUST!! Our oceans make up 99% of the living space on earth and contains about 320,000,000 cubic miles of sea water. Over 70% of our globe is covered by water. Ninety-seven percent of all water on earth is in our oceans.

If world leaders do not immediately engage in a race against time to save the Earth's coral reefs, these vital ecosystems will not survive the global warming and acidification predicted for later this century.

We must do all that is necessary to protect the key components of the life of our planet as the consequences of decisions made now will likely be forever as far as humanity is concerned.

The kitchen is on fire and it's spreading round the house. If we act quickly and decisively we may be able to put it out before the damage becomes irreversible.

Ice melt from a warming Arctic has two major effects on the ocean. First, increased water contributes to global sea-level rise, which in turn affects coastlines across the globe. Second, fresh water from melting ice changes the salinity of the world’s oceans, which can affect ocean ecosystems and deep water mixing.





Increasing sea level rise will be a problem in the future for people living in coastal regions around the globe.

Arctic sea ice reflects sunlight, keeping the polar regions cool and moderating global climate. According to scientific measurements, Arctic sea ice has declined dramatically over at least the past thirty years, with the most extreme decline seen in the summer melt season. The Greenland ice sheet is melting faster than expected, according to a new study led by a University of Alaska Fairbanks researcher.

Arctic ice continued its decline, with hardy, thicker old ice increasingly being replaced with quick-to-melt, thinner young ice.

This winter's maximum Arctic sea ice extent was 5.85 million square miles (15,150,000 square kilometers)—about 278,000 square miles (720,000 square kilometers) less than the Arctic average between 1979 and 2000.

"That's a loss about the size of the state of Texas," said Walter Meier of the National Snow and Ice Data Center (NSIDC) in Boulder, Colorado.

And speaking of Texas, isn't that the home state of the guy whose followers still pretend that global warming is a liberal figment?

Apparently there are different types of arctic ice, and older ice is more resilient than younger ice. Guess which is melting faster: older ice.

Ice a year or more old—thicker, hardier, and less prone to melting than younger ice—was at an all-time low at the end of this past winter, the new report says.

Ice older than two years once accounted for some 30 to 40 percent of the Arctic's wintertime cover and made up 25 percent as recently as 2007.

But last year it represented only 14 percent of the maximum. This year the figure fell to 10 percent.
