Green Oil: Scientists Turn Algae Into Petroleum In 30 Minutes

2013-12-24 06:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Forbes: Scientists at the Pacific Northwest National Laboratory are claiming success in perfecting a method that can transform a pea-soupy solution of algae into crude oil by pressure cooking it for about 30 minutes. The process, called hydrothermal liquefaction, also works on other streams of organic matter, such as municipal sewage. And the crude oil created is lightweight and low in sulfur and can be dropped in to refineries that process fossil crudes. Its a bit like using a pressure cooker, only...

3rd landmark Pennsylvania forest hit by invasive pest, scientists consider possible climate change link

2013-12-22 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Associated Press: Invasive insects have been found in a third landmark Pennsylvania forest, and scientists are considering a possible link to global warming. The U.S. Forest Service reported this week that the hemlock wooly adelgid has been discovered in the Tionesta forest near the New York border. Experts said the insect is often deadly to hemlocks, and the loss of those trees can lead to a cascade of environmental changes for some wildlife, fish, and plants that need the cool, deep shade that the old growth trees...

Climate Scientists, Then and Now, Espousing Responsible Advocacy

2013-12-20 14:48:00| Climate Ark Climate Change & Global Warming Newsfeed

New York Times: Ive long appreciated Gavin A. Schmidts approach to doing and communicating climate science. Schmidt, deputy director of NASAs Goddard Institute for Space Studies, has endured many slings and arrows, not to mention hacks and legal tangles, in building RealClimate.org into what Ive called a vital online touchstone for anyone trying to understand research on the human influence on the planets thermostat. He was tapped this year to give the Stephen H. Schneider Lecture at the annual meeting of...

Tax meat to cut methane emissions, say scientists

2013-12-20 11:53:00| Climate Ark Climate Change & Global Warming Newsfeed

Guardian: Meat should be taxed to encourage people to eat less of it, so reducing the production of global warming gases from sheep, cattle and goats, according to a group of scientists. Several high-profile figures, from the chief of the UN's climate science panel to the economist Lord Stern, have previously advocated eating less meat to tackle global warming. The scientists' analysis, published in the journal Nature Climate Change, takes the contentious step of suggesting methane emissions be cut by...

'Whole world at risk' from simultaneous droughts, famines, epidemics: scientists

2013-12-17 15:29:00| Climate Ark Climate Change & Global Warming Newsfeed

Guardian: An international scientific research project known as the Inter-Sectoral Impact Model Intercomparison Project (ISI-MIP), run by 30 teams from 12 countries, has attempted to understand the severity and scale of global impacts of climate change. The project compares model projections on water scarcity, crop yields, disease, floods among other issues to see how they could interact. The series of papers published by the Proceedings for the National Academy of Sciences (PNAS) shows that policymakers...
