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.

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.

Physics model acts as an 'EKG' for solar panel health

5. September 2018 - 21:02
Researchers have created an algorithm using the physics of panel degradation that can analyze solar farm data from anywhere, essentially as a portable EKG for solar farms.

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.

Mangrove expansion and climatic warming may help ecosystems keep pace with sea level rise

29. August 2018 - 15:13
Biologists have documented that coastal wetlands in the southeastern United States are responding positively to rising temperatures both in their growth and in their ability to build soil to keep pace with sea level rise.

Wilder wildfires ahead?

28. August 2018 - 20:39
At roughly 415,000 acres, Northern California's Mendocino Complex Fire is now the state's largest recorded wildfire, surpassing the record held by Santa Barbara and Ventura counties' Thomas Fire, which occurred less than a year before. Roughly 10 other large-scale conflagrations are threatening the state. And California is not yet even at the height of its wildfire season.

Connectivity explains ecosystem responses to rainfall, drought

27. August 2018 - 22:15
Researchers reveal techniques -- inspired by the study of information theory -- to track how changes in precipitation alter interactions between the atmosphere, vegetation and soil at two National Science Foundation Critical Zone Observatory sites in the western United States.

What is the maximum possible number of Atlantic tropical cyclones? See the year 2005

22. August 2018 - 22:08
Climate simulations and analyses of Atlantic hurricane activity indicate that the record number of tropical cyclones that occurred in 2005 (28 storms) is close to the maximum number that might occur in this region, given existing climate conditions.
