A prominent climate change skeptic told Congress on Monday he no longer doubts that global warming is real and caused by humans, and joined other scientists in urging action to stop it. Physicist Richard Muller, director of the Berkeley Earth Surface Temperature Project, whose two-year research was funded in part by a foundation formed by…

Japan Tsunami Debris Headed For US West Coast

A Russian ship has spotted a floating island of junk passing the Midway Islands northwest of Hawaii - some 2,000 miles from the source of the tsunami.

It takes a long time to cross the Pacific Ocean if you’re a couch, a fridge, or a piece of a house. Roughly 20 tons of debris sucked into the ocean during Japan’s massive tsunami is due to hit U.S. shores sometime in 2014, acording to University of Hawaii scientists. Nikolai Maximenko, a senior researcher…

Wildfires Caused By Climate Change Alter Yellowstone Forests

Climate change in the Greater Yellowstone Ecosystem will increase the frequency of wildfires and alter the composition of the forests by 2050, according to a team of ecologists who modeled the effects of higher temperatures on fire occurrence.

“We are following the long-term effects of fire in the Yellowstone area and encountering some lessons and surprises that challenge the way we think about fire in the area,” said Erica A. H. Smithwick, assistant professor of geography and ecology, Penn State, and principle investigator on the project. “Yellowstone National Park is the first national…

Extreme Weather Linked To Climate Change

"We do know that because of climate change those kinds of events will very, very likely become more common, more frequent, more intense. So what we can say is that these kinds of events that we are seeing are consistent with climate change." (AP Photo/Mike Gullett)

by: Rosanne Skirble via commondreams.org Scientists say storms likely to become more frequent and intense The powerful tornadoes and other extreme weather events that have cut swaths of destruction across the United States over the past month have prompted many to wonder if they are part of a new trend. Are these violent storms the…

The huge tsunami triggered by the 9.0 Tohoku Earthquake destroyed coastal towns near Sendai in Japan, washing such things as houses and cars into the ocean. Projections of where this debris might head have been made by Nikolai Maximenko and Jan Hafner at the International Pacific Research Center, University of Hawaii at Manoa. Maximenko has…

Antarctic Drilling Plan Raises Concerns

Russian scientists used kerosene to keep a drilled hole open in the remote Antarctic Lake Vostok writes Eric Niiler for Discovery News. The big mystery of Lake Vostok and whether it holds ancient microbial life will have to wait for another Antarctic winter to pass. A team of Russian researchers left their remote drilling site…

World’s Largest Super Volcano – The Yellowstone Caldera, Is It Poised To Explode?

Yellowstone National Park’s caldera, which covers a 25- by 37-mile (40- by 60-kilometer) swath of Wyoming, is an ancient crater formed after the last big blast, some 640,000 years ago. The simmering volcano has produced major eruptions—each a thousand times more powerful than Mount St. Helens’s 1980 eruption—three times in the past 2.1 million years.…
