| Posted: 11 Jun 2021 02:40 PM PDT Pine Island Glacier's ice shelf lost about one-fifth of its total area between 2017 and 2020, in three dramatic collapses. Meanwhile the glacier sped up by 12 percent. The rest of the ice shelf, the authors say, could disappear much sooner than previous studies had suggested. |
| Butterflies and moths have difficulty adjusting to a rapidly changing climate Posted: 10 Jun 2021 01:24 PM PDT Climate change exerts great pressure for change on species and biodiversity. A recent study indicates that the few moth and butterfly species (Lepidoptera) capable of adjusting to a changing climate by advancing their flight period and moving further north have fared the best in Finland. In contrast, roughly 40% of Lepidoptera species have not been able to respond in either way, seeing their populations decline. |
| Ocean microplastics: First global view shows seasonal changes and sources Posted: 10 Jun 2021 01:23 PM PDT An estimated 8 million tons of plastic trash enters the ocean each year, and most of it is battered by sun and waves into microplastics -- tiny flecks that can ride currents hundreds or thousands of miles from their point of entry. |
| World-first discovery could fuel the new green ammonia economy Posted: 10 Jun 2021 12:01 PM PDT Scientists have developed a new technique using phosphonium salts that can help drive the future production of green ammonia. This process could reduce the impact of ammonia production on global carbon emissions. Each metric ton of ammonia produced today contributes to roughly 1.9 metric tons of greenhouse emissions. |
| Bacteria: Serving tasty solution to global plastic crisis Posted: 10 Jun 2021 10:57 AM PDT Scientists have devised a novel way of tackling the mounting issue of plastic pollution -- by using bacteria to transform plastic waste into vanilla flavoring. |
| Study of Hurricane Harvey flooding aids in quantifying climate change Posted: 10 Jun 2021 10:56 AM PDT Researchers used a hydraulic model to consider the degree to which human-caused climate change may have affected flooding in Houston in 2017 during Hurricane Harvey. Resources were used to quantify the increase in Houston flood area and depth and to host a portal where other scientists and the public can access and explore the resulting data. |
| Improved climate resilience through better seasonal forecasts Posted: 10 Jun 2021 10:56 AM PDT Lack of water, floods, or crop losses: As a result of climate change, pronounced periods of drought and rainfall are causing human suffering and major economic damage. Precise seasonal forecasts can help to mitigate these consequences. A research team has now been able to improve global forecasts using statistical methods so that they can be used on the regional level. |
| Researchers develop tool to aid in development, efficiency of hydrogen-powered cars Posted: 09 Jun 2021 11:33 AM PDT Researchers are addressing one aspect of creating fuel cells that can convert hydrogen and oxygen safely into water by developing new computational tools and models needed to better understand and manage the conversion process. |
| Aspirin takes the headache out of ecological restoration Posted: 09 Jun 2021 11:33 AM PDT New research has shown how a readily available, cheap and safe-to-use product found in the medicine cabinet of most homes could be the key to better ecological restoration practices with major benefits for the environment and agriculture. The study revealed that aspirin, which naturally occurs in the bark of the willow tree and other plants, can improve the survival of grass species important for ecological restoration and sustainable pasture when applied in a seed coating. |
