A Bright Climate Future Shines in ‘What’s Possible’

Created specifically for, and presented to world leaders at the 2014 United Nations Climate Summit in New York, this cool short film portrays climate change as a challenging, but solvable problem. Written by Scott Z. Burns, and produced by Lyn Davis Lear, it features the narration of none other than Morgan Freeman and stirring music by composer Hans Zimmer. Its hopeful tone reminds me of the reboot of Cosmos which recently aired on FOX which also dealt in-part with global warming.

By itself, ‘What’s Possible’ is just a single, small step on our journey to dealing with man-made climate change. Hopefully, the world leaders who experienced it, understood its message and what it means for future generations. Time is growing ever-shorter to deal with climate change which will surely be humanity’s defining challenge for the next 50 years. As Carl Sagan said in his famous essay The Pale Blue Dot:

“The Earth is the only world known, so far, to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment, the Earth is where we make our stand.”

Will our species stand up as Carl said, or will we continue to be consumed with short-term monitory greed and political posturing? I prefer to think we’ll come to our senses and do, not only what’s possible, but what’s right.

Greenland’s Disappearing Ice Lakes

While the battle rages between climate deniers and the consensus of the scientific community, strange things are afoot in Greenland. The PBS series NOVA documents the country’s rapidly changing landscape with the help of survey photographer James Balog. Extreme Ice is broken into six parts but the most ominous segment deals with Greenland’s strange disappearing lakes.

In recent years the summer melt season in Greenland has grown hotter and now lasts two weeks longer than it did only a decade ago. This has resulted in huge, fresh water lakes forming on the ice sheet surface. Some of these lakes are miles in diameter and up to 50 feet deep. Although these melt lakes contain hundreds of thousands of gallons of water, satellite imagery has recorded their disappearances in just the span of a few hours. Years ago it was believed the water was simply re-absorbed into the surrounding ice, but recent surveys have discovered something more dangerous. The water is boring down through the ice to the bedrock below and lubricating the entire ice sheet of Greenland. The implications of this, if true, are staggering.

One such amazing lake event was witnessed first hand by the NOVA team and documented for the special. The entire 60 minute broadcast is available on the PBS website and is worth your time. Watching these incredible frozen landscape melt away is strangely beautiful but deeply unsettling. As climate skeptics dominate the media and introduce measures in government bent on denying action to stop the effects of man-made warming, Greenland is slowly but surely slipping away. The debate about what’s causing climate change may never end, but the real question now is what are we doing to prepare for the coming disaster?

Wilkins Ice Shelf Close to Collapse

News today that scientists in Antarctica are reporting that the Wilkins Ice Shelf is “imminently” close to breaking away from the Antarctic Peninsula. The shelf, which is roughly the size of Connecticut, has been destabilizing for the past 20 years and is now on the verge of collapse.

Since the mass is already floating, the breakup won’t raise global sea levels, but it is none-the-less distressing. Wilkins, like all ice in Antarctica, is formed over thousands of years by accumulated and compacted snow. Surveys of the ice shelf over the past century reveal that it had been stable until the 1990’s. In February 2008, the shelf dropped 164 square miles (425 square kilometers) of ice. In May it lost a 62-square-mile chunk.

Meanwhile a new joint report by Muyin Wang of the Joint Institute for the Study of Atmosphere and Ocean and James E. Overland of the National Oceanic and Atmospheric Administration’s Pacific Marine Environmental Laboratory says that Arctic sea ice is melting faster than expected. Overland and Wang combined sea-ice observations with six complex computer models to predict a decline from about 2.8 million square miles normally to 620,000 square miles within 30 years.

Despite all of the apparent evidence, recent polls indicate that fewer and fewer Americans are concerned with global warming. While its difficult to focus attention on environmental matters in the midst of a planet-wide recession, climate change is indeed happening and will continue unless action is taken. The science is speaking to us, we’re apparently just not listening.

UPDATE: It’s happened. The BBC is reporting that according to satellite imagery taken on Sunday, April 5th, the Wilkins Ice Shelf finally snapped. You can watch their report regarding the break up at The Huffington Post.

New Pieces of the Climate Puzzle

News out of Moscow this morning that Russian scientists are evacuating a research station near the North Pole early due to the increasing effects of climate change. Usually the floating ice station is abandoned in late August, but this year the 21 researchers and two dogs will leave now, in mid July.

Meanwhile, on the opposite end of the earth, satellite photos of the Wilkins Ice Shelf in Antarctica reveal that the huge tract of ice is “hanging by a thread”. Neal Young who is a glaciologist with the Antarctic Climate and Ecosystems Cooperative Research Centre in Hobart, says the breakup of the Wilkins Ice Shelf is inevitable and could lead to the de-stabilization of the entire peninsula.

Just two more examples of what is happening around the globe due to climate change. And while the ice caps melt, species die and we continue to pump out millions of tons of pollutants, George Bush has decided that his administration can’t be bothered to do anything about it. Not only that, but we have discovered that Vice President Dick Cheney edited a recent EPA report on greenhouse gasses, and just today Bush lifts the executive ban on off-shore oil drilling. Instead of funding new research into alternative and clean energy sources, this administration continues its long conflict of interest with big oil and the fossil fuel industry to help pollute our environment while contributing to global warming.

Worst. President. Ever.
