Impact of rising sea temperatures on marine life — ScienceDaily

Global warming or climate change. It doesn’t matter what you call it. What matters is that right now it is having a direct and dramatic effect on marine environments across our planet. “More immediately pressing than future climate change is the increasing frequency and severity of extreme ‘underwater heatwaves’ that we are already seeing around […]

Upper ocean temperatures hit record high in 2020

Arctic sea smoke is a result of frigid air passing over relatively warm water; the phenomenon is rare,… view more  Credit: Shaoqing Wang Even with the COVID-19-related small dip in global carbon emissions due to limited travel and other activities, the ocean […]

Cold snap brings Spain lowest temperatures in 20 years

In this photo made available on Tuesday, Jan. 12, 2021, by the European Space Agency, a view of a Copernicus Sentinel-2 image of Madrid, Spain. The image appears to have been taken in black and white. In fact, it is a true-colour image – but the heaviest snowfall in 50 years has blanketed the region, […]

Catalyzing ammonia formation at lower temperatures with ruthenium — ScienceDaily

Nitrogen is an essential nutrient for plant growth. While about 80% of earth is nitrogen, it is mostly contained in the atmosphere as gas, and hence, inaccessible to plants. To boost plant growth, especially in agricultural settings, therefore, chemical nitrogen fertilizers are needed. A crucial step in the production of these fertilizers is the synthesis […]

Turning the heat down: Catalyzing ammonia formation at lower temperatures with ruthenium

Rising temperatures lead to collapse of intact permafrost soils — ScienceDaily

Around a quarter of the ground in the northern hemisphere is permanently frozen. These areas are estimated to contain about twice as much carbon as the world’s current atmosphere. New research says that these permafrost soils are not only increasingly thawing out as the Earth becomes warmer, but also releasing that carbon, which accelerates the […]

Will Rising Temperatures Make Rice Too Toxic?

Rice feeds about half the world, but it is vulnerable to rising temperatures. Increased heat boosts the arsenic uptake from soil to rice plants, perhaps to toxic levels for infants. A new analysis presented at AGU’s virtual Fall Meeting 2020 revealed the root cause of this potentially poisonous transfer, providing another clue for […]

Innovative proton conductor developed to be effective at high temperatures — ScienceDaily

A collaborative research team, including Los Alamos National Laboratory, University of Stuttgart (Germany), University of New Mexico, and Sandia National Laboratories, has developed a proton conductor for fuel cells based on polystyrene phosphonic acids that maintain high protonic conductivity up to 200 C without water. They describe the material advance in a paper published this […]
