Gas-Giant Exoplanets Generally Stay Close To Their Parent Stars, Research Finds

Gas-giant planets are far more likely to orbit very closely to their parent star than they are to orbit at distances farther away, according to new research made possible by the Gemini Observatory’s Planet-Finding Campaign. “It seems that gas-giant exoplanets are like clinging offspring,” says Michael Liu of the University of Hawaii’s Institute for Astronomy

Small Dams on Chinese River Cause More Harm Than Large Dams

Damming Chinese rivers has been in the public consciousness for many years now, if for no other reason than for the impact the construction of the Three Gorges Dam had on the surrounding region: the 400 mile long reservoir of the Three Gorges Dam has flooded 13 cities, 140 towns, 1352 villages, and 100,000 acres of China’s

Escape from Climate Change Similar for Land and Sea Life

How fast do animal and plant populations on land have to travel to stay ahead of climate change and remain in the climates they prefer? And how fast is it for plant and animal populations in the oceans? Despite differences in overall warming, the answer, is about the same. “That average rates of environmental change

Ice Age Carbon Came Not from the Pacific

A new study has found that the Northeast Pacific was not an important reservoir for the carbon that is believed to be responsible for the end of the last Ice Age, throwing scientists back to the proverbial drawing board as they digest this shift in their theories.

Drought Could Hamper Carbon Sequestration in US

A new study supported by the National Science Foundation and the US Department of Energy has concluded that forests and other terrestrial ecosystems in the contiguous United States of America can sequester up to 40 percent of the nation’s fossil fuel carbon emissions.

New Study Shows Nitrogen Lowers CO2 Levels in Forests

Scientists have concluded that forests with excessive nitrogen concentrations reduce the amount of carbon dioxide released into the atmosphere. During a ten year study in Michigan by the National Science Foundation, researchers intentionally fertilized forests with two to three times the current levels of nitrogen. These levels mimic the predicted nitrogen levels of the near
