Vatican science panel calls attention to the threat of glacial melt

Science Daily: A panel of some of the world's leading climate and glacier scientists co-chaired by a Scripps Institution of Oceanography, UC San Diego researcher issued a report commissioned by the Vatican's Pontifical Academy of Sciences citing the moral imperative before society to properly address climate change.

The co-authors of "Fate of Mountain Glaciers in the Anthropocene" list numerous examples of glacial decline around the world and the evidence linking that decline to human-caused changes in climate and air pollution. The threat to the ways of life of people dependent upon glaciers and snow packs for water supplies compels immediate action to mitigate the effects of climate change and to adapt to what changes are happening now and are projected to happen in the future.

"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 authors write in a declaration prefacing the report. "The believers among us ask God to grant us this wish."

Scripps Climate and Atmospheric Scientist Veerabhadran Ramanathan co-chaired the working group with Nobel Laureate Paul Crutzen, formerly affiliated with Scripps and Lennart Bengtsson, former head of the European weather forecasting center.

…"The widespread loss of snow and ice in the mountain glaciers is one of the most visible changes attributable to global climate change. The disintegration of many small glaciers in the Himalayas is most disturbing to me since this region serves as the water tower of Asia and since both the greenhouse gases and air pollutants like soot and ozone contribute to the melting," said Ramanathan, who has been a member of the Pontifical Academy of Sciences since 2004.

…Though scientists usually refrain from proposing action, Ramanathan said the circumstances warranted advancing suggestions from the working group. The authors recommend pursuit of three measures: immediate reduction of worldwide carbon dioxide emissions, reduction of concentrations of warming air pollutants such as soot, ozone, methane and hydroflurocarbons by up to 50 percent, and preparation to adapt to climate changes that society will not be able to mitigate….
