An Ice Free Arctic - Coming soon


This summer, the Arctic lost an area of sea ice equivalent to the state of Maine every day for a month. When the meltback was over in September, the Arctic shed an area of ice the size of Canada and Texas combined — a 40 percent decline over the historical average.
And just last month, scientists reported that the pace of ice loss in Greenland is five times greater than it was in the 1990′s, a development they called "extraordinary."

That's where James Balog, star of the new film Chasing Ice, comes in.  After personally witnessing the melting of glaciers on an assignment for National Geographic, he started a groundbreaking project to document the demise of the world's ice. Called the Extreme Ice Survey, Balog and his team put 27 cameras in place around the world and have taken pictures of glaciers every hour of daylight since.

Watch Chasing Ice. Bring your family, bring your friends, watch it on the big screen if you can. It will fill you with awe for the beauty of ice, admiration for the tenacity of Balog and his crew, and terror at the scale of changes we're creating on earth.

Vatican Report on Glaciers and Climate Change

We call on all people and nations to recognise the serious and potentially irreversible impacts of global warming caused by the anthropogenic emissions of greenhouse gases and other pollutants, and by changes in forests, wetlands, grasslands, and other land uses. We appeal to all nations to develop and implement, without delay, effective and fair policies to reduce the causes and impacts of climate change on communities and ecosystems, including mountain glaciers and their watersheds, aware that we all live in the same home. By acting now, in the spirit of common but differentiated responsibility, we accept our duty to one another and to the stewardship of a planet blessed with the gift of life. 
Climate change is shrinking the world's mountain glaciers, whose retreat creates new risks for humans and sensitive ecosystems alike, warns a new report commissioned by the Roman Catholic Church.
"The widespread loss of ice and snow in the world's mountain glaciers is some of the clearest evidence we have for global changes in the climate system," concludes the analysis, which will be delivered to Pope Benedict XVI. It was assembled by an international team of experts at the behest of the Pontifical Academy of Sciences, the Vatican's non-denominational scientific arm.
The report warns of "serious and potentially irreversible impacts of global warming caused by the anthropogenic emissions of greenhouse gases, and by changes in forests, wetlands, grasslands, and other land uses," urging steep cuts in the world's output of heat-trapping pollutants.
Failure to do so will imperil vulnerable ecosystems and human societies that depend on glaciers for freshwater, it says, including a huge swath of Central Asia where mountain glaciers store water for millions of people. Inaction also leaves some communities vulnerable to flooding from unstable meltwater lakes that can burst without warning, causing outburst floods and mudslides.
"We are committed to ensuring that all inhabitants of this planet receive their daily bread, fresh air to breathe and clean water to drink as we are aware that, if we want justice and peace, we must protect the habitat that sustains us," the document continues.

Retreating Glaciers - Then and Now

In 1921, George Mallory, a British mountaineer, took a black-and-white photograph of Mount Everest. The photo, now legendary, shows the world’s highest peak in the distance and an S-shaped river of ice running toward the foreground: the Rongbuk glacier.

Three years ago, David Breashears, a mountaineer, photographer and filmmaker, returned to the very spot where Mr. Mallory stood to take the photograph and updated the vista. The change is sobering.

Rather than ancient snow pack, only an empty rock-strewn riverbed remains: the glacier has lost 320 vertical feet of ice mass in the intervening years in what researchers describe as a striking effect of global warming.
