Climate change will reduce water availability during dry seasons and increase it during wet seasons around the globe, new research suggests. It also finds there will be large regional variations in water-related impacts.

Levels of carbon dioxide in the atmosphere are fluctuating more than they used to from one season to another, according to observations from the HIPPO field project. This may be a sign of significant changes in northern ecosystems.

A new study by an NCAR researcher shows that small- to moderate-size volcanoes have helped slow down warming over the last decade, while industrial emissions of Sun-blocking sulfur dioxide over Asia have contributed relatively little to the slowdown.

Broadcast meteorologists are a leading source of information about the atmosphere for the public, but many avoid mentioning global warming. New research finds barriers that may keep them from addressing the science of climate change on the air.

A team of researchers, including NCAR scientist Carl Schmitt, are climbing high in the Peruvian Andes to assess the extent to which the white ice is being darkened by ash and other particulates that are emitted by nearby industrial operations. The dark particles can accelerate glacial melting, eventually threatening runoff that supplies water for millions of South American residents.

New research points to gravity waves, which ripple unseen through the atmosphere, as the culprit in many cases of clear-air turbulence. If those waves can be forecast, the research suggests that planes in many cases could be rerouted around them.
