Climate change!

Climate change~!

This picture shows how much damage the global warming had caused. In just a few decades, almost half of the ice glacier has melt. When the ice glacier melts into water, it takes much more space and so it caused flood. When it floods, it will spread to some other countries and those people living at the area will suffer. Those animals living underwater will die as they are unable to survive in such areas.

Scientists have assumed that any change caused by humans would occur over many decades. They are no longer so sure. As climatologist Peter deMenocal put it, "When I began my Ph.D. in 1986, the conventional wisdom was that it took 1,000 years to end an ice age; in '91 that figure was lowered to 100 years, and then just two years later, Richard Alley at Penn State published a paper about climate changing in two to five years." So I suspect that in another few decades, all the ice will melt and the world had to come to an end.
