AHIR JONAI, India >> The wall of water raced through narrow Himalayan gorges in northeast India, gathering speed as it raked the banks of towering trees and boulders. When the torrent struck their island in the Brahmaputra river, the villagers remember, it took only moments to obliterate their houses, possessions and livestock.
No one knows exactly how the disaster happened, but everyone knows whom to blame: neighboring China.
“We don’t trust the Chinese,” says fisherman Akshay Sarkar at the resettlement site where he has lived since the 2000 flood. “They gave us no warning. They may do it again.”
About 500 miles east, in northern Thailand, Chamlong Saengphet stands in the Mekong river, in water that comes only up to her shins. She is collecting edible river weeds from dwindling beds. A neighbor has hung up his fishing nets, his catches now too meager.
Using words bordering on curses, they point upstream, toward China.
The blame game, voiced in vulnerable river towns and Asian capitals from Pakistan to Vietnam, is rooted in fear that China’s accelerating program of damming every major river flowing from the Tibetan plateau will trigger natural disasters, degrade fragile ecologies, divert vital water supplies.

TIMBÍO, Colombia — Like most of the small landowners in Colombia’s lush mountainous Cauca region, Luis Garzón, 80, and his family have thrived for decades by supplying shade-grown, rainforest-friendly Arabica coffee for top foreign brands like Nespresso and Green Mountain. A sign in the center of a nearby town proclaims, “The coffee of Cauca is No. 1!”
But in the last few years, coffee yields have plummeted here and in many of Latin America’s other premier coffee regions as a result of rising temperatures and more intense and unpredictable rains, phenomena that many scientists link partly to global warming.
Coffee plants require the right mix of temperature, rainfall and spells of dryness for beans to ripen properly and maintain their taste. Coffee pests thrive in the warmer, wetter weather.
Bean production at the Garzóns’ farm is therefore down 70 percent from five years ago, leaving the family little money for clothing for toddlers and “thinking twice” about sending older children to college, said Mr. Garzon’s 44-year-old son, Albeiro, interviewed in a yellow stucco house decorated with coffee posters and madonnas.
The shortage of high-end Arabica coffee beans is also being felt in New York supermarkets and Paris cafes, as customers blink at escalating prices. Purveyors fear that the Arabica coffee supply from Colombia may never rebound — that the world might, in effect, hit “peak coffee.” Continue reading
An increase in heavy precipitation that has afflicted many countries is at least partly a consequence of human influence on the atmosphere, climate scientists reported in a new study.
In the first major paper of its kind, the researchers used elaborate computer programs that simulate the climate to analyze whether the rise in severe rainstorms, heavy snowfalls and similar events could be explained by natural variability in the atmosphere. They found that it could not, and that the increase made sense only when the computers factored in the effects of greenhouse gases released by human activities like the burning of fossil fuels.
As reflected in previous studies, the likelihood of extreme precipitation on any given day rose by about 7 percent over the last half of the 20th century, at least for the land areas of the Northern Hemisphere for which sufficient figures are available to do an analysis.
The principal finding of the new study is “that this 7 percent is well outside the bounds of natural variability,” said Francis W. Zwiers, a Canadian climate scientist who took part in the research. Continue reading
KALAMAULA, Molokai – Sunlight will be providing the power needed to run lights, electronics and air conditioning at the Nature Conservancy’s office on Molokai beginning Wednesday, the environmental organization announced.
Rising Sun Solar of Maui installed the office’s 8.88-kilowatt photovoltaic array on the roof of the building in the Molokai Industrial Park on the hot and sunny leeward side.
“We were able to basically cover all of our energy needs and put a cap on our energy costs into the future,” said Suzanne Case, the conservancy’s Hawaii executive director. “It’s good for Hawaii both economically and in terms of sustainability.”
Tapping into sun power will help with the organization’s energy costs on Molokai, which has some of the highest electrical rates in the nation, according to Matias Besasso, a partner with Rising Sun Solar.
“Not only can it reduce costs, but it can lead to job creation and greater energy independence and self-sufficiency for Molokai’s people,” he said.
The conservancy’s Molokai director, Ed Misaki, said the solar energy system has been planned for three years.
“Going green is one of our big goals,” he said. Continue reading
A North Atlantic ocean system also caused more intense storms, a new study revealed
Slowing of the North Atlantic Ocean current system appears to be the reason for more frequent major storms and re-advancing of the glacial age in Hawaii 15,400 years ago, according to a new study.
“These connections are pretty remarkable — a current pattern in the North Atlantic affecting glacier development thousands of miles away in the Hawaiian Islands,” said Oregon State University professor Peter Clark, one of the study’s authors.
Glaciers in Hawaii? Yes — during and just after the last ice age, and the study is shedding light on modern planetary thermodynamics.
Some climate scientists believe global warming could eventually disturb the Gulf Stream in the Atlantic, creating colder temperatures in Europe and elsewhere.
University of Hawaii professor Axel Timmermann said the study confirms his research and that of other scientists that used climate models to predict that a weakening of certain North Atlantic currents would produce more westerly winds and intensified storms in Hawaii. Continue reading
SAN DIEGO — In a laboratory where almost all the test tubes look green, the tools of modern biotechnology are being applied to lowly pond scum.
Foreign genes are being spliced into algae and native genes are being tweaked.
Different strains of algae are pitted against one another in survival-of-the-fittest contests in an effort to accelerate the evolution of fast-growing, hardy strains.
The goal is nothing less than to create superalgae, highly efficient at converting sunlight and carbon dioxide into lipids and oils that can be sent to a refinery and made into diesel or jet fuel.
“We’ve probably engineered over 4,000 strains,” said Mike Mendez, a co-founder and vice president for technology at Sapphire Energy, the owner of the laboratory. “My whole goal here at Sapphire is to domesticate algae, to make it a crop.”

SAN FRANCISCO— The Center for Biological Diversity today filed a formal petition seeking to protect 83 imperiled coral species under the Endangered Species Act. These corals, all of which occur in U.S. waters ranging from Florida and Hawaii to U.S. territories in the Caribbean and Pacific, face a growing threat of extinction due to rising ocean temperatures caused by global warming, and the related threat of ocean acidification.
Scientists have warned that coral reefs are likely to be the first worldwide ecosystem to collapse due to global warming; all the world’s reefs could be destroyed by 2050.
