Unusual feed supplement could ease gassy cows, reduce their greenhouse gas emissions

Cow belches, a major source of greenhouse gases, could be decreased by an unusual feed supplement developed by a dairy scientist.

Irrigation's cooling effects may mask warming in some regions -- for now

Expanded irrigation has made it possible to feed the world's growing billions -- and it may also temporarily be counteracting the effects of climate change in some regions, say scientists. But some sources of irrigation water are projected to dry up in coming decades and when they do, people may face the double whammy of food shortages and higher temperatures. A new study pinpoints where the trouble spots may be.

Land-use expert brings satellite data down to Earth

By integrating remote satellite imagery with revelations from door-to-door interviews, geographers are exploring the complex conditions that give rise to a broad range of land-use challenges -- from the reforestation of Vietnam to the spread of Lyme disease in Belgium.

Six times more insect species in tropical mountains than predicted

How many species of insects exist? Researchers found that in tropical mountains there are six times more insects than shown in global calculations. The insects in these areas are also highly specialized in their choice of food.

Melting rate of icecaps in Greenland and Western Antarctica lower than expected

The Greenland and West Antarctic ice caps are melting at half the speed previously predicted, according to analysis of recent satellite data.

Woolly mammoth, woolly rhinoceros and reindeer lived on Iberian Peninsula 150,000 years ago, findings show

Researchers in Spain have gathered together all findings of the woolly mammoth, the woolly rhinoceros and the reindeer in the Iberian Peninsula to show that, although in small numbers, these big mammals -- prehistoric indicators of cold climates -- already lived in this territory some 150,000 years ago.

Scientist offers better ways to engineer Earth's climate to prevent dangerous global warming

There may be better ways to engineer the planet's climate to prevent dangerous global warming than mimicking volcanoes, a climate scientist in Canada says in two new studies.

Carbon mapping breakthrough

By integrating satellite mapping, airborne-laser technology, and ground-based plot surveys, scientists have revealed the first high-resolution maps of carbon locked up in tropical forest vegetation and emitted by land-use practices.
