New research by a team of ecologists and hydrologists shows that water temperatures are increasing in many streams and rivers throughout the United States. The research, published in the journal Frontiers in Ecology and the Environment, documents that 20 major U.S. streams and rivers have shown statistically significant long-term warming.

Public concern about global warming has dropped sharply since the fall of 2008, according to the results of a national survey released this week by researchers at Yale and George Mason universities.

A new analysis of global surface temperatures by NASA scientists finds the past year was tied for the second warmest since 1880. In the Southern Hemisphere, 2009 was the warmest year on record.

Catch share programs result in more consistent and predictable fisheries but do not necessarily improve ecological conditions, according to a new study published online this week by the journal Proceedings of the National Academy of Sciences.

An effective response and social acceptance of the reality of climate change will not be accomplished by scientists delivering ever-increasing amounts of technical information to the public, researchers say in a recent report, and new approaches are needed.

The ocean and the land are natural sponges, or sinks, that absorb carbon dioxide, or CO2, from the atmosphere. But a group of international scientists, including two from NOAA, have found that the emissions are outpacing the ability of the sinks to soak up the excess CO2.

Daily record high temperatures occurred twice as often as record lows over past decade Spurred by a warming climate, daily record high temperatures occurred twice as often as record lows over the last decade across the continental United States, new research shows.

The NOAA El Niño Southern Oscillation (ENSO) Alert System status is that of an "El Niño advisory" of weak El Niño conditions in the tropical Pacific that are expected to develop into a moderate strength El Niño through the winter. The impacts of this warm ENSO on Oregon, Washington, and Idaho are expected to be seen this fall and winter.

The U.S. Department of Interior this week announced the establishment of a Northwest Climate Science Center that will be jointly placed at University of Washington, Oregon State University, and the University of Idaho, with collaborations at research institutions across the Northwest.
