Ice melts, seas rise

It's happening folks:

ILULISSAT, Greenland (CNN) -- From the air, Greenland's ice sheet, the second largest on Earth, appears to be perfectly still.

But below the surface, the ice sheet is in constant motion, as ice built up in the interior pushes toward the coast in the form of massive glaciers. During warmer months, ice from these glaciers melts into the ocean.

It's an age-old process that scientists say has speeded up in recent decades because of global warming.

The fear is that melting ice from Greenland and other Arctic areas could cause sea levels to rise enough to flood low-lying cities, such as Shanghai, China, and New York City, displacing millions of people in the process.

[Climate scientist, Dr. Konrad] Steffen hopes his prediction of a three-foot rise in global sea level by 2100 won't become a reality. But he warned that even if we are able to reduce the world's carbon output from cars and power plants, it will take a long time for Earth's climate to stop warming and seas to stop rising.

"Even if we reduce our carbon dioxide output, the climate will continue to warm," he said. "So even by stopping the increase of carbon dioxide today, we will have a warming, we will have sea level increase."

We are reaping what we have sown.
