Satellite data used to calculate snow depth in mountain ranges

ScienceDaily - 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

ScienceDaily - 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.

Unusually strong positive Indian Ocean Dipole (IOD) event develops, powers severe droughts in Australia, and supports warmer October in Europe.

Severe Weather Europe - 20. Oktoober 2019 - 1:07

There are many global factors and influences that drive our climate and the weather that we feel. A lot of these “drivers” come from the oceans around the world. One such driver (or index) is the Indian Ocean Dipole, also know as the IOD. As the name already suggests, this index can be found in […]

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

ScienceDaily - 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

ScienceDaily - 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

ScienceDaily - 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.
