While people along our nation’s coast experience rising sea levels, residents along the Great Lakes – the Earth’s largest lake system – are adapting to the opposite problem: chronic low water levels and a receding shoreline.
In a perspective now running in Science magazine, Drew Gronewold, a hydrologist at NOAA’s Great Lakes Environmental Research Laboratory, says “the record low water levels in Lake Michigan-Huron in the winter of 2012 to 2013 raise important questions about the driving forces behind water level fluctuations and how water resource management planning decisions can be improved.”
An interview with Mike Alexander, research meteorologist at NOAA’s Earth System Research Lab in Boulder, Colorado, about a new web portal that maps climate change effects in oceans. The new web portal is helping NOAA Fisheries Service with its new process to assess how vulnerable fish stocks are to climate change.
Later this year, NOAA’s National Weather Service will usher into daily operations a sophisticated model called the High-Resolution Rapid Refresh, or HRRR, that will update forecasts hourly over the entire lower 48 United States at extremely sharp resolution using the latest observations from a network of ground and satellite-based sensors, radars and aircraft.
The HRRR provides forecast information at a resolution four times finer than what is currently used in hourly updated NOAA models. This improvement in resolution from 13 to three kilometers is like giving forecasters an aerial photograph in which each pixel represents a neighborhood instead of a city.
As climates change, the lush tropical ecosystems of the Amazon Basin may release more of the greenhouse gas carbon dioxide into the atmosphere than they absorb, according to a new study published Feb. 6 in Nature.
Scientists aboard the NOAA Gulfstream IV aircraft are flying over the Pacific Ocean off the U.S. West Coast this week to measure air pressure, temperature, humidity, wind speed and direction to help better understand atmospheric rivers - narrow conveyor belts of water vapor that can bring beneficial water supply and snowpack as well as create dangerous floods.
NOAA and the U.S. Navy are teaming up with academic and other government scientists to design the next generation of powerful supercomputer models to predict weather, ocean conditions and regional climate change.
Four teams of scientists are beginning projects this month to rewrite computer models that will create faster, lower-cost, better integrated models. These new models will take advantage of new supercomputers that use more energy efficient/lower-cost processors such as those originally developed for the video gaming industry.
A perspective from NOAA and NASA scientists published online on January 29, 2014 in Nature Climate Change addresses a key question surrounding proposals to engineer the Earth’s climate to increase the planet’s reflection of sunlight to counteract climate warming: Could we measure manmade increases in reflectivity?
NOAA-led research using climate model projections concludes the Arctic climate will continue to show major changes over the next decades, but that carbon emission mitigation could slow temperature changes in the second half of the century, according to a paper published by AGU’s Earth’s Future.
Power plants that use natural gas and a new technology to squeeze more energy from the fuel release far less of the greenhouse gas carbon dioxide than coal-fired power plants do, according to a new analysis accepted for publication Jan. 8 in the journal Earth’s Future, a journal of the American Geophysical Union. The so-called “combined cycle” natural gas power plants also release significantly less nitrogen oxides and sulfur dioxide, which can worsen air quality.
Reducing the amount of desert dust swept onto snowy Rocky Mountain peaks could help Western water managers deal with the challenges of a warmer future, according to a new study led by researchers at NOAA’s Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder.
