Jet Stream Changes Since 1960s Linked to More Extreme Weather
January 15, 2018 10:26 AM - University of Arizona

Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, droughts, wildfires and flooding, reports a University of Arizona-led team.

The research is the first reconstruction of historical changes in the North Atlantic jet stream prior to the 20th century. By studying tree rings from trees in the British Isles and the northeastern Mediterranean, the team teased out those regions' late-summer weather going back almost 300 years — to 1725.

Sanchi Oil Spill Contamination Could Take Three Months to Reach Mainland
January 15, 2018 09:45 AM - National Oceanography Centre (NOC)

Water contaminated by the oil currently leaking into the ocean from the Sanchi tanker collision is likely to take at least three months to reach land, and if it does the Korean coast is the most likely location. However, the oil’s fate is highly uncertain, as it may burn, evaporate, or mix into the surface ocean and contaminate the environment for an extended duration.

Lanternfish reveal how ocean warming impacts the twilight zone

New Study From the University of Halle: How Climate Change Alters Plant Growth
January 12, 2018 11:58 AM - Martin Luther University Halle-Wittenberg (MLU)

Global warming affects more than just plant biodiversity - it even alters the way plants grow. A team of researchers at Martin Luther University Halle-Wittenberg (MLU) joined forces with the Leibniz Institute for Plant Biochemistry (IPB) to discover which molecular processes are involved in plant growth. In the current edition of the internationally renowned journal "Current Biology", the group presents its latest findings on the mechanism controlling growth at high temperatures. In the future this could help breed plants that are adapted to global warming.

The Negative Impact of Climate Change on Freshwater Bodies
January 12, 2018 11:56 AM - Ruhr-University Bochum

A lot of research is being conducted into the acidification of the world’s oceans. A recent study has proved that freshwater bodies are likewise affected. Rising carbon dioxide levels could upset the balance of species.

Species identification in the water bottle
January 12, 2018 10:52 AM - Technical University of Munich

Environmental DNA analysis makes it possible to detect water organisms without having to capture them first. For the first time, a team at the Technical University of Munich (TUM) systematically investigated the effect of various environmental factors on environmental DNA analyses. By doing so, the researchers have made an important step towards the standardized application of this method for the monitoring of water bodies.

Thinking outside the box on climate mitigation
January 12, 2018 10:31 AM - International Institute for Applied Systems Analysis

In a new commentary in the journal Nature Climate Change, IIASA researchers argue that a broader range of scenarios is needed to support international policymakers in the target of limiting climate change to under 2°C above pre-industrial levels, and to avoid potential negative environmental and social consequences of carbon dioxide removal on a massive scale. 

NASA Calculated Heavy Rainfall Leading to California Mudslides
January 12, 2018 09:12 AM - NASA / Goddard Space Flight Center

Winter rains falling on recently burned ground triggered deadly mudslides in Santa Barbara County, California on January 9. NASA calculated the amount of rain fall between January 8 and 10, 2018 and calculated the potential for landslides.

Adaptation now: River flood risks increase around the globe under future warming
January 11, 2018 02:22 PM - Potsdam Institute for Climate Impact Research

Rainfall changes caused by global warming will increase river flood risks across the globe. Already today, fluvial floods are among the most common and devastating natural disasters.
