Collapse of the Atlantic Ocean heat transport might lead to hot European summers

24. Aprill 2018 - 18:29
Severe winters combined with heat waves and droughts during summer in Europe. Those were the consequences as the Atlantic Ocean heat transport nearly collapsed 12,000 years ago. The same situation might occur today.

General aviation pilots struggle to interpret weather forecast and observation displays

17. Aprill 2018 - 1:56
When tested on their knowledge of 23 types of weather information, from icing forecasts and turbulence reports to radar, 204 general aviation (GA) pilots were stumped by about 42 percent of the questions. The findings are worrisome.

How does one prepare for adverse weather events? Depends on your past experiences

16. Aprill 2018 - 19:15
With much of the central plains and Midwest now entering peak tornado season, the impact of these potentially devastating weather events will be shaped in large part by how individuals think about and prepare for them. A new study shows that people's past experiences with tornadoes inform how they approach this type of extreme weather in the future, including their perception of the risk.

Atlantic Ocean circulation at weakest point in more than 1,500 years

11. Aprill 2018 - 20:16
New research provides evidence that a key cog in the global ocean circulation system hasn't been running at peak strength since the mid-1800s and is currently at its weakest point in the past 1,600 years. If the system continues to weaken, it could disrupt weather patterns from the United States and Europe to the African Sahel, and cause more rapid increase in sea level on the US East Coast.

Hotter, longer, more frequent -- marine heatwaves on the rise

10. Aprill 2018 - 23:41
We know heatwaves over land have been increasing, but now new research reveals globally marine heatwaves have also been increasing in length, number and intensity over the past century. More intriguing still, this trend has accelerated markedly since 1982.

Silent marine robots record sounds underwater

10. Aprill 2018 - 15:42
Silent marine robots that record sounds underwater are allowing researchers to listen to the oceans as never before. While pilot whales make whistles, buzzes and clicks, pods of hunting dolphins create high-pitched echolocation clicks and larger species such as sperm whales make louder, slower clicks. As well as eavesdropping on marine life, the recordings can be used to measure sea-surface wind speed and monitor storms. The research will be presented at the General Assembly of the European Geosciences Union, Vienna.

Estuaries may experience accelerated impacts of human-caused CO2

2. Aprill 2018 - 23:07
Rising anthropogenic, or human-caused, carbon dioxide in the atmosphere may have up to twice the impact on coastal estuaries as it does in the oceans because the human-caused CO2 lowers the ecosystem's ability to absorb natural fluctuations of the greenhouse gas, a new study suggests.

West Greenland Ice Sheet melting at the fastest rate in centuries

28. Märts 2018 - 21:33
New study from the West Greenland Ice Sheet shows that weather patterns and summer warming combine to drive ice loss that is at the highest levels in at least 450 years.

Weather phenomena such as El Niño affect up to two-thirds of the world's harvests

28. Märts 2018 - 19:00
Large-scale weather cycles, such as the one related to the El Niño phenomenon, affect two-thirds of the world's cropland. In these so called climate oscillations, air pressure, sea level temperature or other similar factors fluctuate regularly in areas far apart in a way that causes rain and temperature patterns to shift significantly.

Are fire ants worse this spring because of Hurricane Harvey?

27. Märts 2018 - 4:33
Ecologists are checking to see if Hurricane Harvey's unprecedented floods gave a competitive boost to fire ants and crazy ants, two of southeast Texas' least favorite uninvited guests.

Alberta's boreal forest could be dramatically altered by 2100 due to climate change

26. Märts 2018 - 18:01
Half of Alberta's upland boreal forest is likely to disappear over the next century due to climate change, a new study shows. The upland forest will be replaced after wildfire by open woodland or grassland, according to research from biologists.

New data confirm increased frequency of extreme weather events

21. Märts 2018 - 19:08
New data show that extreme weather events have become more frequent over the past 36 years, with a significant uptick in floods and other hydrological events compared even with five years ago, according to a new publication.

New interactive map shows climate change everywhere in world

21. Märts 2018 - 18:16
A geography professor has created a new interactive map that allows students or researchers to compare the climates of places anywhere in the world. The map draws on five decades of public meteorological data recorded from 50,000 international weather stations around the Earth. And it uses prediction models to display which parts of the globe will experience the most or least climate change in the next 50 years.

Study of climate change could lead to understanding future of infectious disease

20. Märts 2018 - 18:34
Over the past 34 years, rainfall in Uganda has decreased by about 12 percent even though many of the global climate models predict an increase in rainfall for the area, according to an international team of researchers. Rainfall levels in Uganda impact agriculture, food security, wildlife habitats and regional economics as well as the prevalence of certain diseases.
