| Hydrogen instead of electrification? Potentials and risks for climate targets Posted: 06 May 2021 11:21 AM PDT Hydrogen-based fuels should primarily be used in sectors such as aviation or industrial processes that cannot be electrified, finds a team of researchers. Producing these fuels is too inefficient, costly and their availability too uncertain, to broadly replace fossil fuels for instance in cars or heating houses. For most sectors, directly using electricity for instance in battery electric cars or heat pumps makes more economic sense. |
| Flooding might triple in the mountains of Asia due to global warming Posted: 06 May 2021 09:58 AM PDT A research team has revealed the dramatic increase in flood risk that could occur across Earth's icy Third Pole in response to ongoing climate change. Focusing on the threat from new lakes forming in front of rapidly retreating glaciers, a team demonstrated that the related flood risk to communities and their infrastructure could almost triple. Important new hotspots of risk will emerge, including within politically sensitive transboundary regions of the Himalaya and Pamir. |
| More than one way for animals to survive climate change Posted: 06 May 2021 07:54 AM PDT Researchers found that to live in hotter more desert-like surroundings, and exist without water, there is more than one genetic mechanism allowing animals to adapt. This is important not only for their survival but may also provide important biomedical groundwork to develop gene therapies to treat human dehydration related illnesses, like kidney disease. |
| Microalgae biofuels: Changing carbohydrates into lipids Posted: 06 May 2021 07:54 AM PDT Engineers have developed a technique to repartition carbon resources from carbohydrates to lipids in microalgae. It is hoped that this method can be applied to biofuel production. |
| Zero to hero: Overlooked material could help reduce our carbon footprint Posted: 06 May 2021 07:54 AM PDT Reducing the amount of CO2 in our environment is crucial for mitigating climate change and needs materials that can adsorb CO2 from air under ambient conditions. In a new study, scientists explore the CO2 adsorption properties of zeolite, which has been overlooked in this regard, and report an unprecedented selective adsorption behavior in the extremely lower pressure region and at room temperature, paving the way for its future applications in air purification. |
| Roadmap to expand NY solar energy, meet green goals Posted: 06 May 2021 07:53 AM PDT Solar-power developers need to explore using lower-quality agricultural land for solar energy, incentivize dual-use (combined agriculture and solar) options, avoid concentrated solar development and engage communities early to achieve New York's green energy goals, according to recent research. |
| Ice core chemistry study expands insight into sea ice variability in Southern Hemisphere Posted: 05 May 2021 02:49 PM PDT Sea ice cover in the Southern Hemisphere is extremely variable, from summer to winter and from millennium to millennium, according to a new study. Overall, sea ice has been on the rise for about 10,000 years, but with some exceptions to this trend. Researchers uncovered these findings by examining the chemistry of a 54,000-year-old South Pole ice core. |
| Research confirms trawl ban substantially increases the abundance of marine organisms Posted: 05 May 2021 10:05 AM PDT Biodiversity is of crucial importance to the marine ecosystem. The prohibition of trawling activities in the Hong Kong marine environment for two and a half years has significantly improved biodiversity, a new study has found. Research results showed that the trawl ban could restore and conserve biodiversity in tropical coastal waters. |
| What is driving reductions in residential greenhouse gas emissions in the US? Posted: 05 May 2021 08:14 AM PDT A study finds smarter home construction and decarbonization of electric supply are contributing to lower emissions from individual households, but troubling trends show other factors could begin to cancel out this progress. |
| Methane nibbling bacteria are more active during summer Posted: 05 May 2021 08:14 AM PDT Bacteria that thrive on methane released from the ocean floor are an important barrier preventing the greenhouse gas from reaching the atmosphere. A new study finds that these microbial communities flourish in seabed depressions and are more effective during the summer. |
| Urgent action needed to protect dolphins and porpoises from bycatch in European waters Posted: 05 May 2021 08:13 AM PDT Marine scientists are calling on the EU to adopt a comprehensive plan to protect dolphins and porpoises from fisheries bycatch in European waters. To help address the bycatch issue, which is the primary global threat to dolphins and porpoises, the researchers put forward a framework to reduce bycatch levels. |
