China to spend big to clean up its air


Grist

China plans a five-year, $277 billion spending spree to clean up the country’s killer air.

The government of the heavily polluted nation pledged to clean up its skies after air-pollution levels reached dizzying new heights early this year. The announcement coincides with other nascent environmental initiatives, such as a carbon-trading system to tackle climate change and, bizarrely, legal changes that could see serious polluters executed.

Many wondered whether the pledge to tackle air pollution was mere rhetoric, but this week’s announcement suggests that China is taking the problem seriously. From Reuters:

The money is to be spent primarily in regions that have heavy air pollution and high levels of PM 2.5, the state-run China Daily newspaper quoted Wang Jinnan, vice-president of the Chinese Academy for Environmental Planning as saying. Wang helped draft the plan. …

The new plan specifically targets northern China, particularly Beijing, Tianjin and Hebei province…

Antarctica’s permafrost is melting


Grist

Things are getting ugly on Earth’s underside.

Antarctic permafrost, which had been weathering global warming far better than areas around the North Pole, is starting to give way. Scientists have recorded some of it melting at rates that are nearly comparable to those in the Arctic.

Scientists used time-lapse photography and LiDAR to track the retreat of an Antarctic ice cliff over a little more than a decade. They reported Wednesday in the journal Scientific Reports that the cliff was “backwasting rapidly.” The permafrost that made up the cliff was found to be disappearing nearly 10 times more quickly than was the case during recent geological history. And the rate of melting is picking up pace. From the Los Angeles Times:

Cliff-face measurements of the buried ice in the four-mile-long Garwood Valley revealed melt rates that shifted from a creeping annual rate of about 40,000 cubic feet per year over six…

Arctic methane escape could cost $60 trillion


Grist

An almighty belch is building up deep in the belly of the Arctic, and it’s going to cost the world a pretty penny when it rips.

As the Arctic continues to melt, a 50-gigatonne reservoir of methane trapped in permafrost beneath the East Siberian Sea will be released — perhaps steadily over five decades or perhaps during one sudden grandfatherly burp — and that will cause an estimated $37 trillion to $60 trillion worth of damage. So say researchers in a commentary published Wednesday in the journal Nature.

Methane is a particularly potent greenhouse gas. “Higher methane concentrations in the atmosphere will accelerate global warming and hasten local changes in the Arctic, speeding up sea-ice retreat, reducing the reflection of solar energy and accelerating the melting of the Greenland ice sheet,” the researchers write. “The ramifications will be felt far from the poles.”
