How global warming might affect food security – The Hindu

Between the year 1870 (the first industrial revolution) and today, the global temperature has risen by almost 2 degrees Celsius. This has come about due to more fossil burning (oil, natural gas, coal), which has also increased the carbon dioxide…

Biggest CO2 drop: Real-time data show COVID-19’s massive impact on global emissions

(Potsdam Institute for Climate Impact Research (PIK)) While the ongoing Corona pandemic continues to threaten millions of lives around the world, the first half of 2020 saw an unprecedented decline in CO2 emissions — larger than during the financial crisis of 2008, the oil crisis of the 1979, or even World War II.

Arctic weather observations can improve hurricane track forecast accuracy

(Research Organization of Information and Systems) Comparison of mid-range forecast model accuracy of Atlantic hurricane tracks from 2007 to 2019 revealed that when strong winds associated with upper-level troughs caused hurricanes to move northward, track forecast accuracy was lower. The accuracy of track forecasts in such cases was improved by including data collected over the Arctic Ocean in 2017, by reducing the error in forecasting upper-level troughs. Therefore, additional data collection at high latitudes can improve mid-latitude hurricane track forecasting.

Long-term consequences difficult to predict

(Universität Leipzig) In a longitudinal study, an international research team led by Leipzig University has investigated the consequences of changes in plant biodiversity for the functioning of ecosystems. The scientists found that the relationships between plant traits and ecosystem functions change from year to year. This makes predicting the long-term consequences of biodiversity change extremely difficult, they write in “Nature Ecology & Evolution”.

New open-access book “Inclusive Urbanism” addresses the key issues of urban development

(Technische Universität Dresden) More than half of the world’s population is agglomerated in cities. According to a UN projection, approx. two thirds of the global population will be city dwellers by 2050. As urbanisation progresses, social aspects in urban development become ever more critical. Alongside TU Delft, Department of Urbanism, and the Leibniz Institute of Ecological Urban and Regional Development Dresden (IÖR), TU Dresden has now published the open access publication “Inclusive Urbanism”, which is dedicated to the major issues of urban development.

Multi-institutional team extracts more energy from sunlight with advanced solar panels

(University of Illinois at Urbana-Champaign, News Bureau) Researchers working to maximize solar panel efficiency said layering advanced materials atop traditional silicon is a promising path to eke more energy out of sunlight. A new study shows that by using a precisely controlled fabrication process, researchers can produce multilayered solar panels with the potential to be 1.5 times more efficient than traditional silicon panels.

New algorithm could unleash the power of quantum computers

(DOE/Los Alamos National Laboratory) A new algorithm that fast forwards simulations could bring greater use ability to current and near-term quantum computers, opening the way for applications to run past strict time limits that hamper many quantum calculations.

Noble metal clusters can enhance performance of catalysts and save resources

(Karlsruher Institut für Technologie (KIT) ) Billions of noble metal catalysts are used worldwide for the production of chemicals, energy generation, or cleaning the air. However, the resources required for this purpose are expensive and limited. To optimize the use of resources, catalysts based on single metal atoms have been developed. A research team of Karlsruhe Institute of Technology (KIT) demonstrated that noble metal atoms may assemble to form clusters under certain conditions. Results are reported in Nature Catalysis (DOI: 10.1038/s41929-020-00508-7).

DOI Halts Grants To Eco-Groups For Funding Human Rights Abuses

The Trump administration halted certain grant funding to select environmental organizations, including the World Wildlife Fund, which have used federal money to fund alleged human rights violations in Africa, according to an internal memo. The Department of the Interior (DOI)…

Stellar explosion in Earth’s proximity

(Technical University of Munich (TUM)) When the brightness of the star Betelgeuse dropped dramatically a few months ago, some observers suspected an impending supernova – a stellar explosion that could also cause damage on Earth. While Betelgeuse has returned to normal, physicists from the Technical University of Munich (TUM) have found evidence of a supernova that exploded near the Earth around 2.5 million years ago.
