Assisted Colonization: Saving Species or Creating New Invasives?

Quino Checkerspot Male Many vulnerable species are facing reduced numbers because the adaptations that have served them for thousands of years make them unable to survive small changes in temperature or precipitation. When faced with climate change and other threats to their habitat, some species may not be able to relocate quickly enough to save them from extinction. A new technique called assisted colonization may prove to be an innovative solution.

The objective of the Chinese regulation specifically is "to ensure that citizens, legal persons and other organizations can obtain government information by lawful means and increase government transparency."

Two New Visions for America's Energy Future

gore energy challenge Speaking before an enthusiastic crowd at a sold-out DAR Constitution Hall in Washington, D.C., former Vice President Al Gore issued a challenge to "repower America." Gore's challenge is undoubtedly ambitious: he wants the entire U.S. electricity sector to shift to zero-carbon sources like wind, solar, and geothermal in the next 10 years.

Climate Change Putting Coral Reefs At Risk

The impacts of climate change are already being felt, especially in the most fragile and marginal ecosystems around the world. In particular, coral reefs, which are extremely sensitive to changes in the temperature and acidity of the water in which they form, are being destabilized by a changing ocean environment. Several scientific studies have demonstrated that many of the world's coral reefs are precariously close to total failure. A new study, while confirming this conclusion, does offer some hope.

China's New Ministry of Environmental Protection Begins to Bark, but Still Lacks in Bite

Finding a Safe Level of Carbon Dioxide for the Global Atmosphere: Results of the Tallberg Forum

tallberg forum 2008 Most discussions around international climate change—the Kyoto Protocol, the Lieberman-Warner Bill introduced on the floor of the U.S. Senate last month, and the G8 discussions taking place this week—include targets for emissions of carbon dioxide (CO₂) and other greenhouse gases (GHG). A more direct question was addressed at the Tallberg Forum in Sweden last week: regardless of emissions, how much CO₂ can actually accumulate in the Earth's atmosphere without causing enormous and irreversible impacts on human society and the natural environment?

Video: Air Pollution Means Mexico City Residents Losing Sense of Smell

Street art To the list of air pollution's health effects, add another one: loss of sense of smell.

Mexico City residents can't detect subtle smells as well as residents of neighboring Tlaxcala, researchers at Mexico's National University (UNAM) have reported, though the regions are quite similar in both culture and climate. The primary difference: Mexico City has much higher levels of air pollution.

Invasive Species, China, and the Olympics
leaf miner damage As the Olympic Games approach, China has come under fire for its environmental track record. Tales of Beijing and other cities' infamous pollution and images of highly polluted lakes and rivers have met with demands for action, both within China and internationally, and have produced some meaningful results. Yet another environmental crisis looms: biological invasions. Indeed, while perhaps not as overt as choking smog or pea-green water, the ecosystems of this vast nation are increasingly threatened by invasive species.

Fighting Malaria with DDT: A Decades-Long Debate

Mosquito The global campaign to eradicate malaria in the 1950s and '60s successfully vanquished the disease from the United States and Europe and substantially reduced it in others – in India and Sri Lanka, for instance, malaria cases decreased by 99 percent. Malaria transmission was nearly wiped out in the subtropics, and it was significantly reined in in parts of the Soviet Union, Latin America, and Asia.

About the insecticide that served as a cornerstone of the campaign, the National Academy of Sciences wrote in 1970: "To only a few chemicals does man owe as great a debt." But the same insecticide has become one of today's most infamous chemicals. It is DDT.
