A new study published in the journal Nature Geoscience led by scientists at University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science, and the National Oceanic and Atmospheric Administration’s Atlantic Oceanographic and Meteorological Laboratory, found that human-induced environmental changes around Antarctica…

UMass Amherst scientists propose new method for tracking elusive origins of CO2 emissions from streams

A team of researchers from the University of Massachusetts Amherst that specializes in accounting for the carbon dioxide release by streams, rivers and lakes recently demonstrated that the chemical process known as “carbonate buffering” can account for the majority of emissions in highly alkaline waters.

Extreme Weather as the New Norm: American University Experts Available for Comment

WHAT: As scientists, policymakers and communities continue to grapple with extreme weather events and a changing climate, American University experts are available to comment on a wide range of topics and ramifications. WHEN/WHERE: August 30, 2023 – ongoing; availability in-studio, through email, phone or Zoom WHO: Paul Bledsoe is an adjunct professorial lecturer at the Center for Environmental Policy in AU’s School of Public Affairs.

Researchers Find Global Plant Water Use Efficiency Stalled Due to Climate Change

Researchers at the University of New Hampshire have found that water use efficiency has stalled since 2001 which implies not as much CO2 was being taken in by plants and more water was consumed and that could have implications on carbon cycling, agricultural production and water resources.

Sea ice melt, warming ocean temperatures and emergency response: Experts discuss the return of El Niño

The University of Delaware boasts several experts who can talk about El Niño’s return and its wide-reaching impacts, from record-breaking temperatures to sea ice melt that has been shattering scientists’ expectations.  Wei-Jun Cai: Air-sea CO2 flux; carbon cycling in estuaries…

Affordable and available technologies can curb rising nitrous oxide emissions

Researchers from IIASA and the University of Maryland have found that nitrous oxide, a potent greenhouse gas and stratospheric ozone-depleting substance, could be readily abated with existing technology applied to industrial sources.

Climate Change Threatens Military Readiness

The growing frequency and intensity of heat waves around the globe pose “a substantial, persistent ‘non-combat threat’” to military training and operations, according to experts in environmental, thermoregulatory and cardiovascular physiology.

New Research Suggests Wheat Crops May Be Threatened by Unprecedented Heat and Drought

A recent study led by a researcher at the Friedman School of Nutrition Science and Policy at Tufts University found that the likelihood of extreme temperatures that could affect crop yields has increased significantly in wheat-producing regions of the U.S. and China.

Marine Seagrass Meadows Show Resilience to ‘Bounce Back’ After Die-Offs

A study in Florida Bay, one of the largest global contiguous seagrass systems, examined if a phytotoxin that accumulates as seagrass ecosystems become more enriched in nutrients prevents a marine seagrass, turtlegrass, from recruiting into open bare sediment following die-off events. While they do “bounce back,” long-term monitoring indicates the timeframe for recovery after major die-off events is at least a decade. Turtlegrass can successfully recruit into open bare sediment following die-off events due to biomass partitioning.

A Day and Night Difference: Molecular Composition of Aerosols Differs from Day to Night

Aerosols particles in the atmosphere are an important factor in the Earth’s climate, but researchers lack information on these aerosols’ molecular composition, especially for aerosols during the day and night above agricultural fields. In this research, scientists examined secondary organic aerosols over agricultural fields in the Southern Great Plains in Oklahoma. They found that the aerosols’ composition and structure differ from day to night and that some aerosols are ultimately from urban sources.

Costs of Natural Disasters Set To Spiral with Continued Rise in CO2 and Global Temperature, Study Shows

Researchers estimated that climate change-related natural disasters have increased since 1980 and have already cost the United States more than $2 trillion in recovery costs. Their analysis also suggests that as atmospheric carbon dioxide levels and the global temperature continue to rise, the frequency and severity of disasters will increase, with recovery costs potentially rising exponentially.

University of Utah and Wilkes Center for Climate Science & Policy now accepting proposals for $1.5 million climate prize

The Wilkes Center for Climate Science & Policy is accepting Phase 1 applications for its $1.5 million Wilkes Center Climate Prize at the University of Utah. The Wilkes Center Climate Prize at the University of Utah recognizes and supports innovative projects that have significant potential to help address the impact of climate change.

FSU researcher finds forest canopies are warmer than previously thought

By: Mark Blackwell Thomas | Published: September 12, 2022 | 4:13 pm | SHARE: A study by a Florida State University researcher finds that temperatures in forest canopies are higher than previous estimates, threatening forests’ vital role in mitigating global warming. Stephanie Pau, an associate professor in the Department of Geography, was part of a team whose study was published in Proceedings of the National Academy of Sciences.

UAlbany-led study finds exposure to sun, heat and humidity can exacerbate symptoms of mental disorders

New research links information on New York weather and hospital emergency department visits to assess how summer weather conditions impact people living with mental disorders. Findings can inform strategies to mitigate severe symptoms and improve patient care.

Propane – a solution for more sustainable air conditioning

Current severe heatwaves that will likely increase in severity and frequency in the future are driving a rise in the use of air conditioners, threatening the environment with their high energy consumption and refrigerants with high warming potential. A new study finds that switching to propane as a refrigerant could lessen the global temperature increase from space cooling.

Climate change may be culprit in Antarctic fish disease outbreak

Climate change might be behind an unusual disease outbreak among Antarctic fish. For about a decade, University of Oregon biologists John Postlethwait and Thomas Desvignes have been visiting the West Antarctic Peninsula. They study a unique group of fish that has adapted to the harsh polar environment. But on a 2018 field excursion, they noticed something especially strange: a large number of those fish were afflicted with grotesque skin tumors.

Including all types of emissions shortens timeline to reach Paris Agreement temperature targets

Instead of focusing on carbon dioxide’s effect on future temperature, new research includes the related human-generated emissions of methane, nitrogen oxide and particle pollution. Expanding the scope increases the amount of future warming that is already guaranteed by past emissions, and shortens the timeline to reach the Paris Agreement temperature targets.
