Global Warming: Is It A Scenario Too Scary To Think About?

Experts say scope of the problem makes it hard for people to be optimistic

To Patricia Kremer, climate change is a runaway train carrying Earth toward a forbidding future.

”Just stop the train,” said Kremer, a retiring marine scientist who has witnessed the effects during her studies of the ocean's environments for 30 years. She and her husband, James, who is also about to retire from a career as a marine scientist and professor, work at the University of Connecticut's Avery Point campus.

She is not alone in thinking this. United Nations leader Ban Ki-moon says that whether you call it climate change, global warming or climate disruption, it's “the defining challenge of our age.”

In November, when Ban made his pronouncement, the 2,500 climate scientists from around the world who comprise the U.N.'s Intergovernmental Panel on Climate Change had just issued their strongest alert about the global disaster threatening the future.

”If there is no action before 2012, that's too late,” said Rajendra Pachauri, the scientist and economist who heads the IPCC. “What we do in the next two to three years will determine our future.” More >>>

Honda Rolls Out Petroleum-Free Fuel Cell Car

TOCHIGI, Japan, June 16, 2008 (ENS) - Honda's first hydrogen fuel cell powered vehicle other than concept cars rolled off the assembly line today in Tochigi Prefecture at the world's first dedicated fuel cell vehicle manufacturing facility.

Nineteen years in development, the FCX Clarity was designed from scratch as a fuel cell vehicle. Only water is emitted from the tailpipe - no greenhouse gases, no smog or soot or other by-products of burning gasoline. More>>>

Climate change threatens reef fish

SYDNEY (AFP) — 16 June 2008 - Climate change threatens to devastate coral reef fish populations and increase the likelihood of fishery collapses, Australian researchers warned Monday.

Coral reefs' vulnerability to global warming has already been established by researchers, but the fish living in the reefs are also at risk, James Cook University's Centre for Excellence in Coral Reef Studies found. "We have already seen episodes of mass die-off of corals as a result of warmer waters associated with global warming, the problem for specialist coral fish is that when the corals die, the fish have nowhere else to go," the centre's Philip Munday said. Munday said there were some 4,000 fish species living in or around coral reefs, providing livelihoods and a major source of sustenance to an estimated 200 million people worldwide. More>>>

Capture carbon to avert catastrophic climate change, say world's scientists .

June 10, 2008 - The world must have a clear plan to fit power stations with facilities to capture carbon dioxide within a year to prevent "catastrophic" climate change, the world's leading scientific bodies said today.

But the warning came as Britain's support for the technology was blasted as "woefully inadequate" by experts. The Royal Society, along with the scientific academies of the eight leading industrial nations and of five other countries including China and India, says that millions will be at risk from food and water shortages if action is not taken.

Changing Jet Streams May Alter Paths of Storms and Hurricanes

Thursday, April 17, 2008 Stanford, CA—The Earth’s jet streams, the high-altitude bands of fast winds that strongly influence the paths of storms and other weather systems, are shifting—possibly in response to global warming.

Scientists at the Carnegie Institution determined that over a 23-year span from 1979 to 2001 the jet streams in both hemispheres have risen in altitude and shifted toward the poles. The jet stream in the northern hemisphere has also weakened. These changes fit the predictions of global warming models and have implications for the frequency and intensity of future storms, including hurricanes. More >>>

Back to 1988 on CO2, Says NASA’s Hansen

James E. Hansen, the NASA climate scientist who has long had a habit of pushing past where many colleagues dare go in describing the risks posed by global warming, has done it again.

He and eight co-authors have drafted a fresh paper arguing that the world has already shot past a safe eventual atmospheric concentration of carbon dioxide, which they say would be around 350 parts per million, a level passed 20 years ago. (The atmosphere currently holds about 385 parts per million of the greenhouse gas.)

Looking at evidence from past climate swings and greenhouse-gas concentrations, he concludes that a sustained concentration of carbon dioxide at double the 280 parts per million that prevailed for hundreds of millenniums before the industrial revolution would — after a host of slowly-responding feedbacks kicked in to amplify the temperature rise — result in an enormous warming of some 11 degrees Fahrenheit (6 degrees Celsius).

Latest round of UN climate change talks kicks off in Germany

2 June 2008 – Talks on strengthening international action on global warming have begun in Bonn, Germany under the United Nations Framework Convention on Climate Change (UNFCCC).

The two-week round of negotiations will focus on furthering governments’ commitments to the Kyoto Protocol on climate change, and will include discussion on how industrialized countries can meet their emissions reduction targets beyond the first phase of the Protocol, which ends in 2012.
“There is a huge global consciousness that urgent international action needs to be taken this year and the next. So we can expect good progress at this meeting,” said UNFCCC Executive Secretary Yvo de Boer. More >>>
