When reporting climate-driven human migration, place matters

13. November 2019 - 22:31
Location matters when talking about how climate might or might not be driving migration from Central America. Climate research in the dry corridor region revealed a complex pattern of change. If you average across the entire region you wouldn't see a trend going either way.

Stalled weather patterns will get bigger due to climate change

13. November 2019 - 14:51
Climate change will increase the size of stalled high-pressure systems that can cause heat waves, droughts and other extreme weather, according to a new study.

Deep neural networks speed up weather and climate models

12. November 2019 - 23:49
A team of environmental and computation scientists is using deep neural networks, a type of machine learning, to replace the parameterizations of certain physical schemes in the Weather Research and Forecasting Model, an extremely comprehensive model that simulates the evolution of many aspects of the physical world around us.

This is what the monsoon might look like in a warmer world

12. November 2019 - 18:02
In the last interglacial period on Earth about 125,000 years ago, the Indian monsoon was longer, more extreme and less reliable than it is today. This is the conclusion drawn after analyses of a dripstone from a cave in north-eastern India, combining various methods that provide information about supra-regional and local weather phenomena and the climate dynamics of the past.

Hurricanes have become bigger and more destructive for USA

11. November 2019 - 22:06
A new study shows that hurricanes have become more destructive since 1900, and the worst of them are more than 3 times as frequent now than 100 years ago. A new way of calculating the destruction unequivocally shows a climatic increase in the frequency of the most destructive hurricanes that routinely raise havoc on the North American south- and east coast.

Turbulence creates ice in clouds

8. November 2019 - 17:28
Vertical air motions increase ice formation in mixed-phase clouds. This correlation was predicted theoretically for a long time, but could now be observed for the first time in nature. Using laser and radar equipment, the team measured the vertical air velocity and ice formation in thin mixed-phase clouds.

Using AI to predict where and when lightning will strike

8. November 2019 - 14:48
Researchers have developed a novel way of predicting lightning strikes to the nearest 10 to 30 minutes and within a radius of 30 kilometers. The system uses a combination of standard data from weather stations and artificial intelligence.

Satellite tracking shows how ships affect clouds and climate

5. November 2019 - 17:44
By matching the movement of ships to the changes in clouds caused by their emissions, researchers have shown how strongly the two are connected.

Satellites are key to monitoring ocean carbon

4. November 2019 - 15:33
Satellites now play a key role in monitoring carbon levels in the oceans, but we are only just beginning to understand their full potential.

Why are big storms bringing so much more rain? Warming, yes, but also winds

30. Oktoober 2019 - 0:24
For three hurricane seasons in a row, storms with record-breaking rainfall have caused catastrophic flooding in the southern United States. A new analysis explains why this trend is likely to continue with global warming: Both the higher moisture content of warmer air and storms' increasing wind speeds conspire to produce wetter storms.

New AI deep learning model allows earlier, more accurate ozone warnings

29. Oktoober 2019 - 19:14
Researchers have developed an artificial intelligence-based ozone forecasting system, which would allow local areas to predict ozone levels 24 hours in advance.

Satellite data used to calculate snow depth in mountain ranges

22. Oktoober 2019 - 19:11
Bioscience engineers have developed a method to measure the snow depth in all mountain ranges in the Northern Hemisphere using satellites. This technique makes it possible to study areas that cannot be accessed for local measurements, such as the Himalayas.

Climate warming promises more frequent extreme El Niño events

21. Oktoober 2019 - 22:33
New research, based on 33 historical El Niño events from 1901 to 2017, show climate change effects have shifted the El Niño onset location from the eastern Pacific to the western Pacific and caused more frequent extreme El Niño events since the 1970's. Continued warming over the western Pacific warm pool, driven by anthropogenic climate change, promises conditions that will trigger more extreme events in the future.

Land management practices to reduce nitrogen load may be affected by climate changes

19. Oktoober 2019 - 1:10
Nitrogen from agricultural production is a major cause of pollution in the Mississippi River Basin and contributes to large dead zones in the Gulf of Mexico. Illinois and other Midwestern states have set goals to reduce nitrogen load through strategies that include different land management practices. A new study uses computer modeling to estimate how those practices may be affected by potential changes in the climate, such as increased rainfall.

Last year's extreme snowfall wiped out breeding of Arctic animals and plants

16. Oktoober 2019 - 0:15
In 2018, vast amounts of snow were spread across most of the Arctic region and did not melt fully until late summer, if at all. Researchers documented the consequences of this extreme weather event at Zackenberg, Northeast Greenland by extensively monitoring all components of the local ecosystem for more than 20 years, allowing them to compare life in the extreme year of 2018 to other, more 'normal,' years.

Artificial intelligence and farmer knowledge boost smallholder maize yields

15. Oktoober 2019 - 23:46
Farmers in Colombia's maize-growing region of Córdoba had seen it all: too much rain one year, a searing drought the next. Yields were down and their livelihoods hung in the balance. To better deal with climate stress, farmers in Colombia's maize-growing region of Córdoba needed information services that would help them decide what varieties to plant, when they should sow and how they should manage their crops.

Believing in climate change doesn't mean you are preparing for climate change

8. Oktoober 2019 - 17:46
Researchers found that although coastal homeowners may perceive a worsening of climate change-related hazards, these attitudes are largely unrelated to a homeowner's expectations of actual home damage.

Another casualty of climate change? Recreational fishing

7. Oktoober 2019 - 17:36
Another casualty of climate change will likely be shoreline recreational fishing, according to new research. The study finds some regions of the U.S. may benefit from increasing temperatures, but those benefits will be more than offset by declines in fishing elsewhere.

The last mammoths died on a remote island

7. Oktoober 2019 - 15:17
Isolation, extreme weather, and the possible arrival of humans may have killed off the holocene herbivores just 4,000 years ago.

Northern forests have lost crucial cold, snowy conditions

3. Oktoober 2019 - 18:40
Winter conditions are changing more rapidly than any other season and researchers have found clear signs of a decline in frost days, snow covered days and other indicators of winter that could have lasting impacts on ecosystems, water supplies, the economy, tourism and human health.
