Tipping points: Where may abrupt impacts from climate change occur?

Tipping points: Where may abrupt impacts from climate change occur?

Climate change has increased concern over possible large and rapid changes in the physical climate system, which includes Earth’s atmosphere, land surfaces, and oceans. Some of these changes could occur within a few decades or even years, leaving little time for society and ecosystems to adapt. A new report from the National Research Council extends […]

Industrial age helps some coastal regions capture carbon dioxide, surprise finding shows

Coastal portions of the world’s oceans, once believed to be a source of carbon dioxide (CO2) to the atmosphere, are now thought to absorb as much as two-thirds more carbon than they emitted in the preindustrial age, researchers estimate. These coastal areas, which now appear to operate as one of the several types of so-called […]

More logging, deforestation may better serve climate in some areas

More logging, deforestation may better serve climate in some areas

Replacing forests with snow-covered meadows may provide greater climatic and economic benefits than if trees are left standing in some regions, according to a Dartmouth College study that for the first time puts a dollar value on snow’s ability to reflect the sun’s energy. The findings suggest more frequent logging or deforestation may better serve […]
