Scientists poring over military and satellite imagery have mapped the unimaginable: a network of rivers, streams, ponds, lakes and even a waterfall, flowing over the ice shelf of a continent with an annual mean temperature of more than -50C. - From EcoWatch
scientists report in the journal Nature that they studied photographs taken by military aircraft from 1947 and satellite images from 1973 to identify almost 700 seasonal networks of ponds, channels and braided streams flowing from all sides of the continent, as close as 600km to the South Pole and at altitudes of 1,300 meters.
But the companion study, led by the polar scientist Robin Bell of the Lamont-Doherty Observatory suggests that drainage on the Nansen Ice Shelf might help to keep the ice intact, perhaps by draining away the meltwater in the dramatic waterfall the scientists had identified.
The EDGI noticed that the wording changed from how wind can "help the nation reduce emissions of greenhouse gases and other air pollutants, diversify its energy supply, provide cost-competitive electricity to key regions across the country, and reduce water usage for power generation" to how wind "helps the nation increase its competitiveness, diversify its energy supply, increase energy security and independence, reduce emissions of air pollutants, save water that would otherwise be used by thermal power generation, and provide cost-competitive electricity across the country." "Together, the changes collectively downplay the climate benefits of each form of technology and distance the agency from the idea that they might be used to reduce dependence on fossil fuels, instead emphasizing their economic advantages.
The March for Science calls for science-based policymaking, and the People's Climate March puts this value into practice by opposing Trump's reckless anti-climate agenda, defending the integrity of climate science and democracy, and standing up for justice." The March for Science and People's Climate March will bring the fight for truth and justice right to the doorstep of the Trump administration.
"We have all heard of the impact of melting ice on sea level rise, but the public also need to be aware that places around the world depend on glaciers for their water and are going to come under increasing stress, and we already see how water shortages lead to all kinds of conflict," Baker said.
