High-intensity fires can destroy marshy peatlands and cause them to emit huge amounts of their stored carbon into the atmosphere as greenhouse gases, but a new Duke University study finds low-severity fires spark the opposite outcome. By creating a decay-inhibiting crust on clumps of moist soil particles within the peatland, the smaller surface fires help protect the stored carbon and enhance peatlands' long-term storage of it, even during times of extreme drought.
A new study by the University of Southampton has revealed why some corals exhibit a dazzling colorful display, instead of turning white, when they suffer 'coral bleaching' -- a condition which can devastate reefs and is caused by ocean warming. The scientists behind the research think this phenomenon is a sign that corals are fighting to survive.
New discoveries on the regulation of plant emissions of isoprenoids can help in fighting climate change - and can become key to the production of valuable green chemicals.
Cooling, drying, and light attenuation are major impacts of fire aerosols on the global terrestrial ecosystem productivity.
Scientists have created the first ever large-scale map of microscopic algae as they bloomed across the surface of snow along the Antarctic Peninsula coast. Results indicate that this 'green snow' is likely to spread as global temperatures increase.
Discussions of drought often center on the lack of precipitation. But among climate scientists, the focus is shifting to include the growing role that warming temperatures are playing as potent drivers of greater aridity and drought intensification.
A new study looked at US tax policy as it relates to carbon dioxide (CO2), from 2015 through 2030. The study found only limited short-term opportunities for decarbonization (reducing greenhouse gas emissions) outside the electricity sector. The result is substantial CO2 tax revenue. The findings shed light on future tax policy decisions.
In a new study, researchers from the Colorado School of Public Health at the University of Colorado Anschutz Medical Campus call attention to the emergence of mosquito-borne viral outbreaks in West Africa, such as dengue (DENV), chikungunya (CHIKV) and Zika (ZIKV) viruses.
Scientists engineering valuable microbes for renewable fuels and bioproducts have developed an efficient way to identify the most promising varieties. Researchers at the University of Illinois at Urbana-Champaign developed a high-throughput screening technique to rapidly profile medium-chain fatty acids produced in yeast -- part of a larger group of free fatty acids that are key components in essential nutrients, soaps, industrial chemicals, and fuels. The breakthrough will save researchers time and labor as they design sustainable alternatives to petroleum-based chemical manufacturing processes.
In a new study, researchers from the University of Copenhagen have demonstrated that penguins in Antarctica emit copious amounts of nitrous oxide via their feces. So much so, that the researchers went "cuckoo" from being surrounded by penguin poop.
