| Uncharted waters: Blown fuses and other troubles send the New Clermont back to the docks as the team regroups Editor's Note: A team of Rensselaer Polytechnic Institute students was traveling up New York's Hudson River this week on the New Clermont , a 6.7-meter boat outfitted with a pair of 2.2-kilowatt hydrogen fuel cells to power the boat's motors. Their journey began September 21 from Manhattan's Pier 84 and was to cover 240 kilometers (at a projected speed of 8 kilometers per hour). After making several stops along the way, the crew originally expected to arrive back at Rensselaer Polytech's campus in Troy, N.Y., on September 25. This is the fourth of Scientific American.com's blogs chronicling this expedition, called the New Clermont Project . [More] rss.sciam.com |
How Can Humanity Avoid or Reverse the Dangers Posed by a Warming Climate? Wetlands from Bangladesh to Florida submerged. Drought and devastating heat in important granaries such as the Yangtze floodplain in China or Ukraine. Rains that come too often or too hard in India or the U.S. Northeast. The list of potentially devastating impacts from climate change is a long one. But with greenhouse gas emissions continuing to climb and concentrations in the atmosphere rising by roughly two parts per million (ppm) a year, climate catastrophes are looking more and more imminent.

Waiting to Inhale: Deep-Ocean Low-Oxygen Zones Spreading to Shallower Coastal Waters A plague of oxygen-deprived waters from the deep ocean is creeping up over the continental shelves off the Pacific Northwest and forcing marine species there to relocate or die. Since 2002 tongues of hypoxic, or low-oxygen , waters from deeper areas offshore have slipped into shallower near-shore environments off the Oregon coast, although not close enough to be oxygenated by the waves. The problem stems from oxygen reduction in deep water, a phenomenon that some scientists are observing in oceans worldwide, and that may be related to climate change. [More] rss.sciam.com |

Will birth control solve climate change? An additional 150 people join the ranks of humanity every minute, a pace that could lead our numbers to reach nine billion by 2050. Changing that peak population number alone could save at least 1.4 billion metric tons of carbon from entering the atmosphere each year by 2050, according to a new analysis--the equivalent of cutting more than 10 percent of fossil fuel burning per year.
