How will climate change stress the power grid? Hint: Look at dew point temperatures

24. September 2018 - 21:40
A new study suggests the power industry is underestimating how climate change could affect the long-term demand for electricity in the United States. The research describes the limitations of prediction models used by electricity providers and regulators for medium- and long-term energy forecasting. It outlines a new model that includes key climate predictors that researchers say present a more accurate view of how climate change will alter future electricity demands.

National parks bear the brunt of climate change

24. September 2018 - 16:16
Human-caused climate change has exposed US national parks to conditions hotter and drier than the rest of the nation, says a new study quantifying for the first time the magnitude of climate change on all 417 parks in the system. Without action to limit greenhouse gas emissions, many small mammals and plants may be brought to the brink of extinction by the end of the century, the study shows.

Extra Arctic observations can improve predictability of tropical cyclones

21. September 2018 - 16:24
Scientists have found that additional weather observations in the Arctic can help predict the track and intensity of tropical and mid-latitude cyclones more accurately, improving weather forecasting of extreme weather events.

Diverse forests are stronger against drought

19. September 2018 - 20:30
Researchers report that forests with trees that employ a high diversity of traits related to water use suffer less of an impact from drought. The results, which expand on previous work that looked at individual tree species' resilience based on hydraulic traits, lead to new research directions on forest resilience and inform forest managers working to rebuild forests after logging or wildfire.

A key to climate stabilization could be buried deep in the mud

18. September 2018 - 18:08
While scientists fear that rising temperatures could unleash a 'bomb' of carbon from Earth's soil carbon reservoirs, a new study suggests these reservoirs might actually be more stable than predicted.

Tropics are widening as predicted by climate models, research finds

17. September 2018 - 22:36
Scientists have observed for years that Earth's tropics are widening in connection with complex changes in climate and weather patterns. But in recent years, it appeared the widening was outpacing what models predicted, suggesting other factors were at work. But a new paper finds that the most up-to-date models and the best data match up reasonably well.

More than 4 billion birds stream overhead during fall migration

17. September 2018 - 20:59
Using cloud computing and data from 143 weather radar stations across the continental United States, researchers can now estimate how many birds migrate through the US and the toll that winter and these nocturnal journeys take.

Weather forecasting sheds light on where and when birds will fly

13. September 2018 - 21:20
September is the peak of autumn bird migration, and billions of birds are winging their way south. Using a combination of artificial intelligence and weather forecasting can help scientists to predict the movements of millions of birds and support their conservation goals, according to new research.

NASA gets inside look at large and powerful Hurricane Florence

13. September 2018 - 18:39
NASA's Aqua satellite provided an infrared look at the large and powerful Hurricane Florence early on Sept. 13, 2018 that indicated wind shear was temporarily affecting the southern side of the storm.

Climate-induced soil changes may cause more erosion and flash flooding

13. September 2018 - 18:39
A new study predicts a climate-induced reduction in large soil pores, which may intensify the water cycle and contribute to more flash flooding and soil erosion by the end of the 21st century.

Fire weather prediction improving

12. September 2018 - 20:27
Scientists have created a new fire-weather prediction tool that works with the same weather models that are used every day in fire weather forecasts, and thus can be applied anywhere in the world, regardless of fuel conditions or topography.

In drought and heavy rains, ecosystems function like information communication networks

12. September 2018 - 18:18
How is a telecommunications network like an ecosystem? Tree canopies and the running streams below, or coral reefs and the ocean waters that flow around them, are interconnected components of a larger whole: an ecosystem. These ecosystem parts are in communication with one another, scientists have learned, via signals transmitted among earth, air and water.

'Cloud computing' takes on new meaning for scientists

11. September 2018 - 22:18
Clouds may be wispy puffs of water vapor drifting through the sky, but they're heavy lifting computationally for scientists wanting to factor them into climate simulations. Researchers have turned to data science to achieve better cumulus calculating results.

New study shows ways to maximize temperature-lowering benefits of Chicago's green roofs

6. September 2018 - 19:33
Researchers have created an integrated framework to identify which neighborhoods would benefit most from green roofs -- and provide city officials with a strategic approach to ensure the best return on their investment to beat the heat.

Invasive pines fueled 2017 fires in Knysna, South Africa

6. September 2018 - 17:04
The replacement of natural fynbos vegetation with pine plantations in the southern Cape in South Africa, and the subsequent invasion of surrounding land by invasive pine trees, significantly increased the severity of the 2017 Knysna wildfires. Over four days in June 2017, the Knysna fires burnt 15000 hectares, claiming the lives of seven people and destroying more than 5000 hectares of commercial pine plantations and over 800 buildings.

California: Global warming, El Niño could cause wetter winters, drier conditions in other months

4. September 2018 - 22:04
New research indicates that what future precipitation California gets will be pretty much limited to the winter months -- think deluge-type rainfall rather than snow -- and non-winter months will be even dryer than usual, with little or no rain at all.
