Global warming

Global Warming Kills the Animals


Species Disappear
The latest report from the World Conservation Union says that a minimum of 40 percent of the world’s species are being threatened ... and global warming’s one of the main culprits. [Reuters]


Cannibalistic Polar Bears...
As longer seasons without ice keep polar bears away from food, they start eating each other. [AP]

...And Dying Polar Bears
A recent study completed by the U.S. Geological Survey shows that cannibalism—while brutal—may be the least of the bear’s problems. Many are also drowning, unable to swim in the increased spaces between melting sea ice. Two-thirds of them may be gone by 2050. [National Geographic] [Mongo Bay]

More Bear Attacks
Earlier this year, Moscow warned its citizens to beware of brown bear attacks. In Russia, it’s been too hot in the winter for bears to sleep. When bears can’t hibernate, they get very grouchy and become “unusually aggressive.”[Der Spiegel]

Dying Gray Whales 
Save the whales! Global warming is thwarting majestic gray whales’ struggle to recover from their endangered status. In recent years, more gray whales have been washing up on beaches after starving to death. Culprit: Rising ocean temps, which are killing off their food supply. [Washington Post]


Death March of the Penguins
Scientists blame global warming for the declining penguin population, as warmer waters and smaller ice floes force the birds to travel further to find food. “Emperor penguins ... have dropped from 300 breeding pairs to just nine in the western Antarctic Peninsula.”  [National Geographic] [MSNBC]

Farewell to Frogs
An estimated two-thirds of the 110 known species of harlequin frog in Central and South America have vanished since the 1980s due to the outbreak of a deadly frog fungus ... brought on by global warming. Scientist J. Allen Pound: "Disease is the bullet killing frogs, but climate change is pulling the trigger.” [National Geographic]

Farewell to the Arctic Fox
The White Arctic Fox used to rule the colder climes, but as temperatures warm up, its more aggressive cousin, the Red Fox, is moving North and taking over. [Wired]

Farewell to the Walrus
Walrus pups rest on sea ice while their mothers hunt for food. A new study shows more and more abandoned pups are being stranded on floating islands as ice islands melt. Also, sadly, mother walruses are abandoning them to follow the ice further north. [Mongo Bay]

Farewell to Cute Koala Bears
Australia’s Climate Action Network reports that higher temperatures are killing off eucalyptus trees while higher levels of CO2 in the atmosphere are decreasing the nutritional value of the eucalyptus leaves Koala bears eat. They warn that the cute furry creatures could become extinct in the next few decades. [Science]

Jellyfish Attack
Ouch! At least 30,000 people were stung by jellyfish along the Mediterranean coast last year; some areas boasted more than 10 jellyfish per square foot of water. Thank global warming: Jellyfish generally stay out of the way of swimmers, preferring the warmer, saltier water of the open seas. Hotter temperatures erase the natural temperature barrier between the open sea and the shore. The offshore waters also become more saline, causing the stinging blobs of hurt to move in toward the coastlines (and your unsuspecting legs). [BBC]
