Published Common plastics could passively cool and heat buildings with the seasons



By restricting radiant heat flows between buildings and their environment to specific wavelengths, coatings engineered from common materials can achieve energy savings and thermal comfort that goes beyond what traditional building envelopes can achieve.
Published New twists on tornadoes: Earth scientist studies why U.S. has so many tornadoes



Across the Midwest during the warmer months, studying the sky for signs of storms and tornadoes becomes one of the most popular pastimes. Working at the intersection of climate science and meteorology and using modeling, scientists are looking at the big picture of what causes severe storms and tornadoes -- and what dictates where they occur.
Published Wolves reintroduced to Isle Royale temporarily affect other carnivores, humans have influence as well



In a rare opportunity to study carnivores before and after wolves were reintroduced to their ranges, researchers found that the effects of wolves on Isle Royale have been only temporary. And even in the least-visited national park, humans had a more significant impact on carnivores' lives.
Published US Clean Water Act leaves about 55% of water flowing out of rivers vulnerable to pollution



The Supreme Court ruled last year that rivers that only flow in response to weather events -- called ephemeral streams -- do not fall under the protection of the Clean Water Act. New research suggests that this now leaves many U.S. waterways vulnerable to pollution.
Published Climate change and sea level rise pose an acute challenge for cities with combined sewer systems



Older coastal cities, like Philadelphia, New York and Boston are at risk of being inundated by untreated sewage during floods. Due in part to the design of their combined sewer systems and in part due to sea level rise, these cities could be facing a growing public health crisis as climate change also drives more extreme precipitation. The group recently published research that modeled the potential extent of the problem in a section of the coastal city of Camden, New Jersey, and the effectiveness of one proposed intervention to help protect these communities.
Published Simple new process stores CO2 in concrete without compromising strength



By using carbonated -- rather than still -- water during the concrete manufacturing process, a team of engineers has discovered a new way to store carbon dioxide (CO2) in the ubiquitous construction material.
Published El NiƱo forecasts extended to 18 months with innovative physics-based model



As more attention is drawn to possible severe weather around the world scientists are looking to improve planning for possible droughts, floods and other scenarios. A team of researchers created a new tool that will allow forecasting of El Nino Southern Oscillation by up to 18 months.
Published Future risk of coral bleaching set to intensify globally



Researchers have projected future marine heatwaves will cause coral reefs to be at severe risk of bleaching for longer periods than previously seen.
Published Ocean's loss of oxygen caused massive Jurassic extinction: Could it happen again?



Researchers have found a chemical clue in Italian limestone that explains a mass extinction of marine life in the Early Jurassic period, 183 million years ago. Volcanic activity pumped out CO2, warming oceans and lowering their oxygen levels. The findings may foretell the impact climate change and oxygen depletion might have on today's oceans.
Published Some landfill 'burps' contain airborne PFAS



Many municipal landfills 'burp' gas from decomposing organic matter rather than letting it build up. And burps from buried waste containing per- and polyfluoroalkyl substances (PFAS) can release these 'forever chemicals' into the air, say researchers. Their study reports unexpectedly high levels of airborne PFAS at three landfills and demonstrates that vented gases and liquid by-products called leachates could transport similar amounts of these contaminants to the environment.
Published Small, adsorbent 'fins' collect humidity rather than swim through water



Clean, safe water is a limited resource and access to it depends on local bodies of water. But even dry regions have some water vapor in the air. To harvest small amounts of humidity, researchers developed a compact device with absorbent-coated fins that first trap moisture and then generate potable water when heated. They say the prototype could help meet growing demands for water, especially in arid locations.
Published Plankton researchers urge their colleagues to mix it up



A new article encourages researchers to focus their attention on mixoplankton, providing a set of methodologies to help expand our understanding of this critically important component of the marine ecosystem.
Published Underwater mountains have a big impact on ocean circulation



Colossal undersea mountains, towering up to thousands of metres high, stir up deep sea currents: impacting how our ocean stores heat and carbon. An international team used numerical modelling to quantify how underwater turbulence around these mountains, called seamounts, influences ocean circulation; finding it is an important mechanism in ocean mixing and one that is missing from climate models used in policymaking.
Published Frog 'saunas' a lifeline for endangered frog populations



New biologist-designed shelters will help endangered frogs survive the devastating impacts of a deadly fungal disease by regulating their body temperature to fight off infections.
Published For many urban residents, it's even hotter than their weather app says



There's a strong chance that last week's scorching temperatures were even hotter than reported for those living in underserved urban areas. New research from environmental engineers has shown that citizen science tools used to gauge heat in these urban areas likely understate the problem of heat islands due to a lack of weather stations. The researchers also suggest a statistical method to improve estimates of urban heat.
Published Team aims to improve safety of fertilizers made from wastewater sludge



Fertilizers manufactured from the sludgy leftovers of wastewater treatment processes can contain traces of potentially hazardous organic chemicals, according to a new study. The research provides one of the most comprehensive looks at the chemical composition of so-called biosolids across the country and is the first step toward identifying common chemical contaminants that may need government regulation.
Published Mashed up purple marine bacteria makes an excellent eco-friendly fertilizer



New research reports that biomass made from the purple photosynthetic marine bacterium Rhodovulum sulfidophilum is an excellent nitrogen fertilizer. The biomass fertilizer proved to be just as effective as common inorganic synthetic fertilizers but avoids several side effects that harm the environment, making it an eco-friendly alternative.
Published Fuel treatments reduce future wildfire severity



There is a common belief that prescribed burning, thinning trees, and clearing underbrush reduce risks of the severity of future fires. But is that true? A new project analyzing 40 studies where wildfire burned into different vegetation treatments, spanning 11 western states. Researchers found overwhelming evidence that in seasonally dry mixed conifer forests in the western U.S., reducing surface and ladder fuels and tree density through thinning, coupled with prescribed burning or pile burning, could reduce future wildfire severity by more than 60% relative to untreated areas.
Published Carbon dioxide's heavy stamp on temperature: Doubling CO2 may mean 7 to 14 degree increase



A doubling of the amount of CO2 in the atmosphere could cause an increase in the average temperature on earth from 7 to even a maximum of 14 degrees. That is shown in the analysis of sediments from the Pacific Ocean off the coast of California.
Published Boosting biodiversity without hurting local economies



Protected areas, like nature reserves, can conserve biodiversity without harming local economic growth, countering a common belief that conservation restricts development. A new study outlines what is needed for conservation to benefit both nature and people.
