Revised theory says levels in air must decline, not just stabilizeA group of 10 prominent scientists says that the level of globe-warming carbon dioxide in the air has probably already reached a point where world climate will change disastrously unless the level can be reduced in coming decades. The study is a departure from recent estimates that truly dangerous levels would be reached only later in this century. The paper appears in the current edition of the Open Atmospheric Science...
Scientists are hoping to discover new information on how clouds over the Pacific Ocean can affect the global climate and weather systems. The clouds, some greater than the size of the US, refract sunlight back into space and chill the ocean below. The researchers expect to learn about the clouds' properties and if pollution from activities could alter the arrangement of these cloud systems. The study will engage 200 scientists from 10 countries in the research. An additional team of 20...
By Greg Esposito greg.esposito@roanoke.com 381-1675 Virginia Tech will be the center of the state youth environmental movement this weekend as host of Virginia Power Shift 2008. The gathering, which will include speakers, symposiums and 60 training sessions on environmental issues, was inspired by Power Shift 2007, a national youth conference on global warming held at the University of Maryland. About 6,000 students from across the country gathered at the event to discuss things such as...
U.S. scientists say they've determined curbing carbon dioxide emissions from coal might avert climate danger. Researchers at Columbia University's Earth Institute said the continuing rise in the planet's atmospheric CO2 levels resulting from burning fossil fuels might be kept below harmful levels if emissions from coal are phased out within the next few decades. The researchers, including James Hansen of the U.S. space agency's Goddard Institute for Space Studies and climatologist Pushker...
By Michael McCarthy Environment Editor THE Nasa scientist who first drew attention to global warming 20 years ago appeared in a British court yesterday as a key witness in support of climate change activists charged with damaging a power station. Professor James Hansen gave evidence at Maidstone Crown Court in the case of six Greenpeace members who scaled a 630ft chimney at the Kingsnorth plant in Hoo, Kent, last October in protest against plans to build new coal-fired units there. The...
"Penn & Teller's Bull----!" 10-10:30 p.m. EDT Thursday, Showtime ___ I've seen lots of things on "Penn & Teller's Bull----!," television's only investigative-journalism program run by comic magicians: Hidden-camera pranks where yuppie fools blather on about designer water that actually came from a garden hose. New Age health nuts allowing mollusks to crawl around on their faces to soak up the health benefits of slug slime. Naked people floating around in a zero-gravity chamber for a show on...
Scientist James Hansen says we're toast if we don't take drastic measures against global warming ("Climatologist sounds warning," June 24). Is this the top NASA scientist who doctored temperature stats, and when asked why he had lied he said it was because we need to get people's attention? Al Gore gave the same excuse for his lies, and he attained his goal. A Nobel and an Oscar are a lot of attention. Jennifer Zapata Highland (c) 2008 Deseret News (Salt Lake City).

Attention: Environment Editors Today at the opening of the World Wind Energy Conference in Kingston, Ontario, New World Generation Inc. released field data on a new wind turbine technology that will make wind power more economically viable and commercially attractive. And today is 20 years to the day after climatologist James Hansen first warned the world about climate change. Hansen is now warning that the world may be reaching its "tipping point" unless more action is taken to curb and...
On the 20th anniversary of his landmark congressional testimony, James Hansen, one of the world's leading climate scientists, appeared again before Congress today, calling for the CEOs of oil companies to be tried for high crimes against humanity and nature. Hansen accused executives of firms such as ExxonMobil and Peabody Energy of actively spreading misinformation and doubt about climate change, and compared the CEOs to tobacco company executives who years ago tried to cloud the...
A new climate change assessment has been released by the Bush administration that said human-induced global warming will likely lead to problems like droughts in the U.S. West and stronger hurricanes. This assessment comes four years late and was pushed forward by a court order.This comes as a surprise from President Bush, who now acknowledges that global warming is happening despite his previous denial of climate science throughout most of his presidency. Still, some watchdog groups claim...
