U.N. body to slash ship fuel pollution by 2015
April 4, 2008 01:07 PM - Reuters
LONDON (Reuters) - The world's top maritime body agreed tough new limits on ship fuel pollutants at a week-long meeting that ended on Friday, an industry source said. The United Nations' International Maritime Organization (IMO) measures will sharply curb harmful sulphur emissions by 2015.
Airborne Study Of Arctic Atmosphere, Air Pollution Launched
April 4, 2008 09:32 AM - NASA/Goddard Space Flight Center
This month, NASA begins the most extensive field campaign ever to investigate the chemistry of the Arctic's lower atmosphere. The mission is poised to help scientists identify how air pollution contributes to climate changes in the Arctic. The recent decline of sea ice is one indication the Arctic is undergoing significant environmental changes related to climate warming. NASA and its partners plan to investigate the atmosphere's role in this climate-sensitive region with the Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) field campaign.
Carbon Dioxide Emission Reduction Assumptions Overly Optimistic, Study Says
April 4, 2008 09:29 AM - National Center for Atmospheric Research/University Corporation for Atmospheric Research.
"In the end, there is no question whether technological innovation is necessary--it is," write the authors in the Nature commentary. "The question is, to what degree should policy focus explicitly on motivating such innovation" The IPCC plays a risky game in assuming that spontaneous advances in technological innovation will carry most of the burden of achieving future emissions reductions, rather than focusing on those conditions that are necessary and sufficient for those innovations to occur."
World Bank accused of climate change "hijack"
April 4, 2008 05:26 AM - Reuters
BANGKOK (Reuters) - Developing countries and environmental groups accused the World Bank on Friday of trying to seize control of the billions of dollars of aid that will be used to tackle climate change in the next four decades. "The World Bank's foray into climate change has gone down like a lead balloon," Friends of the Earth campaigner Tom Picken said at the end of a major climate change conference in the Thai capital.
18 states sue EPA over greenhouse gas pollution
April 3, 2008 08:41 AM - Reuters
WASHINGTON (Reuters) - Eighteen states sued the Environmental Protection Agency on Wednesday for failing to limit greenhouse gas emissions from new cars and trucks, one year after the Supreme Court ruled that the agency had the power to do so. The suit seeks EPA's response to the high court's April 2, 2007, ruling, a landmark decision seen as a sharp defeat for the Bush administration's policy on climate change.
Beijing pollution risky for endurance athletes
April 2, 2008 06:41 AM - Reuters
BEIJING (Reuters) - Endurance events at the Beijing Olympics could pose a health risk if they are staged on heavily polluted days, the International Olympic Committee said on Wednesday, although it was prepared to reschedule such events. Hein Verbruggen, chairman of the IOC coordination commission, said there was a small chance of athletes suffering some damage to their health if they took part in events lasting longer than an hour, such as the marathon and cycling road races.
Australia trials underground carbon storage
April 2, 2008 12:53 AM - Reuters
CANBERRA (Reuters) - Australia on Wednesday began pumping 100,000 tons of carbon dioxide underground in a test of carbon storage that environmentalists said would do little to tackle climate change. The CO2 is stripped from a natural gas well but the idea is to see if the scheme can be expanded to capture CO2 from coal-fired power stations, whose emissions are blamed in part for global warming.
GreenDisk: a viable e-waste solution?
April 1, 2008 09:11 AM - , Triple Pundit
Computers are becoming cheaper and easier to manufacture by the minute. Intel's new Atom processor is bound to create a whole new set of net-enabled devices at extremely low cost. While the processor is not out yet and prices are not set in stone, rumors price new "net-top" computers below $200. Cheaper computers make electronic recycling all the more relevant. Computers and gadgets are being replaced more frequently as electronics become obsolete in a matter of months.
EPA criticized over new lead paint rule
April 1, 2008 12:20 AM - Reuters
WASHINGTON (Reuters) - The U.S. Environmental Protection Agency offered a new rule on Monday aimed at shielding children from the risks of lead-based paint, but a watchdog group said the rule needs to be tougher. The rule affects professional contractors who renovate or repair homes, schools or child-care centers built before 1978, when lead-based paint was banned for residential use. Ordered by Congress in 1992, the rule takes effect in April 2010.
Invention: Diamond-cooled nuclear reactor
March 31, 2008 09:37 AM - New Scientist
Nuclear plants can fail when the heat from the reactor is not removed quickly enough from the core. This can happen in pressurised water nuclear reactors if the water in the cooling system boils, because steam is a much poorer conductor of heat than liquid water. These reactors have a primary water cooling system that directly takes heat away from the reactor. It is sealed under huge pressure to prevent it boiling and conducts heat to a secondary water cooling system that is not sealed.
