The Colorado River provides water for more than 30 million people. Increasing demand for that water combined with reduced flow and the looming threat of climate change have prompted concern about how to manage the basin’s water in coming decades. NOAA-funded researchers at the University of Washington and co-authors at eight institutions across the West aim to explain this wide range, and provide policymakers and the public with a framework for comparison.
Scientists this summer are taking one of the most detailed looks ever at the natural and manmade emissions that affect air quality in the Southeast, and their movement and chemical transformations within the atmosphere. The mission should help scientists determine the origin of the fine particles and how they contribute to the haziness in the region and affect regional air quality and temperature trends.
On May 9, the daily mean concentration of carbon dioxide in the atmosphere of Mauna Loa, Hawaii, surpassed 400 parts per million (ppm) for the first time since measurements began in 1958.
As our planet is warming, not only have Earth’s climate zones begun to shift – the pace of change is expected to accelerate, according to a new study led by the NOAA Cooperative Institute for Research in Environmental Sciences at the University of Colorado.
A new observational study that did not use temperature recordings from land stations has confirmed global land warming.
Clouds over the central Greenland Ice Sheet last July were “just right” for driving surface temperatures there above the melting point.
