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?

Obama Proposes ‘Meaningful Action’ on Climate Change

President Barack Obama called for “meaningful progress” on tackling climate change in his State of the Union speech in Washington, DC on Tuesday night. While acknowledging that “no single event makes a trend,” the President noted that the United States had been buffeted by extreme weather events that in many cases encapsulated the predictions of climate scientists.

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

3 Killers: Superstorms, Dark Swans, Sea Level: Superstorm Sandy has provided the most convincing evidence yet that powerful storms and what are called “black swan” storms, combined with sea level rise are pushing barrier islands out from under beach cities.

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

Climate change is hitting the parks hard.

It’s not the only problem they face, but instead one of many.

Light and noise pollution are also culprits.

Will Budget Strapped National Parks Be Able to Respond to Climate Change?

Environmental changes confronting the National Park System are widespread, complex, accelerating and volatile.

The assessment is not good and on closer inspection, things only get worse.

Most Mammals Won’t Flee Climate Change Fast Enough

As the climate changes over the next century, the ranges of nearly 90 percent of mammal species will shrink — in many cases because animals won’t be able to get to areas where the climate is going to become suitable for them, says new research.

Across the Western Hemisphere, the study also found, nearly 10 percent of mammals will be unable to move fast enough to keep up with changes in climate. In some areas, such as the Amazon, that number will be as high as 40 percent.

Mexico Passes Climate Change Law

As Mexico’s Popocatepetl volcano continues to spew ash and greenhouse gases, the Mexican people themselves have resolved to reduce emissions of carbon dioxide.

A law recently passed by the Mexican legislature will reduce emissions of carbon dioxide by 30 percent below business-as-usual levels by 2020, and by 50 percent below 2000 levels by 2050, reported Nature. By 2024, Mexico will also derive 35 percent of its electricity from renewable resources, according to the new law.
