Hotter Earth Cooks Up More Thunderstorms

If you follow climate science at all, you’ve probably heard that a warming world is likely to generate more nasty weather and a lot more weather extremes, kind of like the extreme droughts and then torrential flooding that Colorado, New Mexico and other western states have experienced. Well that also goes for severe thunderstorms and tornadoes, according to a new study by researchers who used a new computer simulation to test the conditions which generate tornadoes. Read more

Methane Bomb: Arctic Thawing Could Cost $60 Trillion

Rapid warming of the Arctic could result in economic costs of $60 trillion – roughly the size of the entire world economy last year – according to a new analysis.

Ultimate Petition: One Billion for Climate Action

There are lots of petitions flying around the Internet these days, but none quite so ambitious as that of Ranga B. Myneni. His petition has a single sentence that he hopes will be endorsed by a billion humans by the time Earth Day rolls around in 2014. Yeah, that’s no typo: One Billion people. Here’s what the petition says:

Dear Secretary-General of the United Nations Ban Ki-moon,

We, the People of the Earth, request You to act judiciously and expeditiously to protect the Earth from anthropogenic climate change.

Respectfully,

People of the Earth”

But… will it work?

Skating Rinks Monitor Climate Change

After Canadian scientists predicted that global warming will eventually be the demise of backyard skating rinks, a group of geographers at Wilfrid Laurier University in Waterloo created RinkWatch. In just 20 days, 630 volunteers signed up to keep tabs on the condition of their home rinks.

It turns out that your Christmas tree could be a super-greenhouse gas crusader! Who knew?!

Xmas Trees Absorb ‘Super’ Greenhouse Gas: Your Christmas tree and its brethren are absorbing methane, a super greenhouse gas that they were previously suspected of emitting. In fact, previous studies put the global methane output by plants at between 62 and 236 teragrams each year. That’s not small potatoes (if you will pardon the vegetable pun), but 10 to 30 percent of all methane entering the atmosphere.

Humans Changing Saltiness of the Seas: When you hear about climate change it’s most often about melting glaciers and sea ice, increasing frequency of heatwaves and powerful storms. Maybe, just maybe, you’ll hear about the acidification of the oceans too. What you don’t hear about is the saltiness of the seas. But that’s changing too, according to a new piece of research just published in Geophysical Research Letters

DON’T PANIC! Christmas isn’t threatened by the warming Arctic and uptick in ice loss… Santa has relocated his base of operations to Greenland:

"The North Pole location is officially a myth," said Ilbereth, Kringle’s head spokeself. "We are now located in northern Greenland, on solid ground." The new facility has been named North Pole Station in order to avoid confusing children or give Hollywood producers an excuse to remake all of the classic holiday movies. "And not to slight the people of Greenland, to whom we are eternally grateful, but Greenland doesn’t carry quite the same holiday cachet as the North Pole," explained Ilbereth.

Interesting side note:

As far back as 10 years ago Discovery News provided exclusive reports on the growing struggles Santa Claus’ helpers were facing due to ice losses at the North Pole.

Greenland Loses 200 Million Tons of Ice Per Year:

Just how much is 200 million tons of ice? Roughly, it’s the amount needed to fill enough railroad coal cars to encircle the Earth.”

World Bank Fears Devastating 4.0 Degree Warming: "A four-degree warmer world can and must be avoided. We need to hold warming below two degrees," said World Bank President Jim Yong Kim. "Lack of ambitious action on climate change threatens to put prosperity out of reach of millions and roll back decades of development."

…and as deadly Hurricane Sandy proved, after rampaging through the Caribbean and US, weather extremes are only going to get worse… Read more

Wild Drill Monkeys Unable to Deal With Warming Climate

Monkeys called wild drills, already an overhunted species, may see a dramatic population decline if their forest home dries out and vegetation becomes sparser amid warming temperatures, researchers report.

Elephant Seals Swimming Deeper As Waters Warm

Elephant seals are in it deep due to climate change…deep in the ocean that is. Elephant seals from Marion Island in the southwest Indian Ocean are swimming further beneath the surface as their prey also moves into cooler, deeper waters.

"This prey is moving down to greater depths presumably due to the increasing water temperatures and this is forcing the seals to follow them," explained Horst Bornemann from the Alfred Wegener Institute.

Salmon Find a New Run

The shrinking of a glacier offers up a new opportunity for salmon in Southeast Alaska.
