Scientists have found a way to engineer the atomic-scale chemical properties of a water-splitting catalyst for integration with a solar cell, and the result is a big boost to the stability and efficiency of artificial photosynthesis.
Led by researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), the project is described in a paper published this week in the journal Nature Materials.
Nuevos hallazgos sugieren que la tasa a la que el CO2 se está acumulando en la atmósfera se ha estancado en los últimos años debido a que la vegetación de la Tierra está tomando más carbono del aire que en décadas anteriores.
It is well-established in the scientific community that increases in atmospheric CO2 levels result in global warming, but the magnitude of the effect may vary depending on average global temperature. A new study, published this week in Science Advances and led by Tobias Friedrich from the International Pacific Research Center (IPRC) at the University of HawaiÊ»i at MÄnoa, concludes that warm climates are more sensitive to changes in CO2 levels than cold climates.
A new study by University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researchers found that the Indian Ocean’s Agulhas Current is getting wider rather than strengthening. The findings, which have important implications for global climate change, suggest that intensifying winds in the region may be increasing the turbulence of the current, rather than increasing its flow rate.
La formación de dióxido de azufre a partir de la oxidación del sulfuro de dimetilo (DMS) y por tanto, el enfriamiento de las nubes sobre los océanos, parece estar sobrevalorada en los modelos climáticos actuales. Esto concluyen los científicos del Instituto Leibniz para la Investigación Troposférica (TROPOS) de un estudio modelo sobre los efectos del DMS sobre la química atmosférica.
As atmospheric carbon dioxide (CO2) levels rise, very few coral reef ecosystems will be spared the impacts of ocean acidification or sea surface temperature rise, according to a new analysis. The damage will cause the most immediate and serious threats where human dependence on reefs is highest.
A new analysis in the journal Plos One, led by Duke University and the Université de Bretagne Occidentale, suggests that by 2050, Western Mexico, Micronesia, Indonesia, parts of Australia and Southeast Asia will bear the brunt of rising temperatures. Reef damage will result in lost fish habitats and shoreline protection, jeopardizing the lives and economic prosperity of people who depend on reefs for tourism and food.
