Global Warming Kills the Planet

Greenland’s Melting
Greenland is melting at a rate of 52 cubic miles per year—much faster than once predicted. If Greenland’s entire 2.5 million cubic kilometers of ice were to melt, it would lead to a global sea level rise of 7.2 meters, or more than 23 feet. [LA Times]

Less Ice in the Arctic
The amount of ice in the Arctic at the end of the 2005 summer “was the smallest seen in 27 years of satellite imaging, and probably the smallest in 100 years.” Experts said it’s the strongest evidence of global warming in the Arctic thus far. [Washington Post]

The Northwest Passage Becomes a Reality
Remember the “Northwest Passage”? For centuries, explorers were obsessed with the almost-mythical idea of northern sea route connecting the Atlantic and Pacific. Well...it’s here. So much of the ice cover in the Arctic disappeared this summer that ships were able to take recreational trips through the Arctic Sea, and scientists say so much of the ice cover will disappear in upcoming years that the passage could be open to commercial shipping by 2020.

Ice Shelf in Antarctica Bites the Dust
In 2002, a chunk of ice in Antarctica larger than the state of Rhode Island collapsed into the sea. British and Belgian scientists said the chunk was weakened by warm winds blowing over the shelf ... and that the winds were caused by global warming. [ENS]

Ice Shelf in Canada Bites the Dust
In 2005, a giant chunk of ice the size of Manhattan broke off of a Canadian ice shelf and began free floating westward, putting oil drilling operations in peril. [Reuters]

Say Farewell to Glaciers
“In Glacier National Park, the number of glaciers in the park has dropped from 150 to 26 since 1850. Some project that none will be left within 25 to 30 years.” [AP]

The Green, Green Grass of Antarctica
Grass has started to grow in Antarctica in areas formerly covered by ice sheets and glaciers. While Antarctic hair grass has grown before in isolated tufts, warmer temperatures allow it to take over larger and larger areas and, for the first time, survive through the winter. [UK Times]

The Swiss Foothills
Late last summer, a rock the size of two Empire State Buildings in the Swiss Alps collapsed onto the canyon floor nearly 700 feet below. The reason? Melting glaciers. [MSNBC]

Giant “Sand Seas” in Africa
Global warming may unleash giant “sand seas” in Africa—giant fields of sand dunes with no vegetation—as a shortage of rainfall and increasing winds may “reactivate” the now-stable Kalahari dune fields. That means farewell to local vegetation, animals, and any tourism in the areas. [National Geographic]

Florida’s National Marine Sanctuary in Trouble
Global warming is “bleaching” the coral in the Florida Keys National Marine Sanctuary, killing the coral, tourism, and local fish that live among the coral for protection. [Washington Post]

The Oceans are Turning to Acid
It sounds like a really bad sci-fi movie, but it’s true: The oceans are turning to acid! Oceans absorb CO2 which, when mixed with seawater, turns to a weak carbonic acid. Calcium from eroded rocks creates a “natural buffer” against the acid, and most marine life is “finely tuned” to the current balance. As we produce more and more CO2, we throw the whole balance out of whack and the oceans turn to acid. [CS Monitor]

Say Goodbye to the Great Barrier Reef
According to the U.N., the Great Barrier Reef will disappear within decades as “warmer, more acidic seas could severely bleach coral in the world-famous reef as early as 2030.” [CBC News]

Mediterranean Sea? Try the Dead Sea.
Italian experts say thanks to faster evaporation and rising temperatures, the Mediterranean Sea is quickly turning into “a salty and stagnant sea.” The hot, salty water “could doom many of the sea's plant and animal species and ravage the fishing industry.” [AP]
