Ice age climate analysis reduces worst-case warming expected from rising CO2

A detailed reconstruction of climate during the most recent ice age, when a large swath of North America was covered in ice, provides information on the relationship between CO2 and global temperature. Results show that while most future warming estimates remain unchanged, the absolute worst-case scenario is unlikely.

GW Experts Available: EPA Strengthens Rule on Harmful Soot Pollution

The U.S. Environmental Protection Agency is strengthening limits on soot, a harmful air pollution in which studies have shown that fine particles kill thousands of Americans every year. According to The Washington Post, the stricter standards could prevent thousands of premature…

Study links changes in global water cycle to higher temperatures

A new study takes an important step toward reconstructing a global history of water over the past 2,000 years. Using geologic and biologic evidence preserved in natural archives — including globally distributed corals, trees, ice, cave formations and sediments — the researchers showed that the global water cycle has changed during periods of higher and lower temperatures in the recent past.

New Study Finds That the Gulf Stream is Warming and Shifting Closer to Shore

The Gulf Stream is intrinsic to the global climate system, bringing warm waters from the Caribbean up the East Coast of the United States. As it flows along the coast and then across the Atlantic Ocean, this powerful ocean current influences weather patterns and storms, and it carries heat from the tropics to higher latitudes as part of the Atlantic Meridional Overturning Circulation.
A new study published today in Nature Climate Change now documents that over the past 20 years, the Gulf Stream has warmed faster than the global ocean as a whole and has shifted towards the coast. The study, led by Robert Todd, a physical oceanographer at the Woods Hole Oceanographic Institution (WHOI), relies on over 25,000 temperature and salinity profiles collected between 2001 and 2023.

FSU atmospheric scientist available to comment on what El Niño conditions mean for winter, spring

By: Patty Cox | Published: October 2, 2023 | 12:30 pm | SHARE: El Niño, the climate phenomenon characterized by warmer-than-average sea surface temperatures across the equatorial central and eastern Pacific Ocean, has far-reaching impacts on weather patterns across the globe.  El Niño events can last for several months up to a year or more and typically peak in the winter months of the Northern Hemisphere, so we’re likely to see El Niño conditions continue to strengthen over the coming months, said Alyssa Atwood, an assistant professor in Florida State University’s Department of Earth, Ocean and Atmospheric Science, part of the College of Arts and Sciences.

LLNL scientists among finalists for new Gordon Bell climate modeling award

To Cut Global Emissions, Replace Meat and Milk with Plant-Based Alternatives

Replacing 50% of meat and milk products with plant-based alternatives by 2050 can reduce agriculture and land use related greenhouse gas (GHG) emissions by 31% and halt the degradation of forest and natural land, according to new research in Nature Communications journal.

Curbing waste improves global food security but has limited environmental benefits

Reducing waste is one way to help combat hunger around the world, but stricter control over food loss and waste does not lead to better environmental outcomes, according to researchers at the University of California, Irvine and the University of Colorado Boulder. In a paper published recently in Nature Food, the scientists stress that curbing food spoilage increases the amount of produce in markets, which leads to lower costs.

Meet the world’s 1st outdoor sweating, breathing and walking manikin

In the coming decades, every region in the U.S. is expected to experience higher temperatures and more intense heat waves. Thousands of people around the country die from heat-related illnesses each year, and in Maricopa County alone in 2022 there were 425 heat-related fatalities, a 25% increase from the previous year. ASU researchers aim to better understand heat stress on the human body and what makes hot weather so deadly using ANDI the world’s 1st outdoor sweating, breathing and walking manikin.

Air Force Weather-funded research aims to improve predictability of extreme weather

As extreme weather devastates communities worldwide, scientists are using modeling and simulation to understand how climate change impacts the frequency and intensity of these events. Although long-term climate projections and models are important, they are less helpful for short-term prediction of extreme weather that may rapidly displace thousands of people or require emergency aid.

Less Rain in Town, More Rain on the Farm: the Effects of Urbanization and Irrigation on Mid-Atlantic Summer Precipitation

Researchers investigated how large-scale urbanization and irrigation in the United States affect the three dominant types of summer precipitation in the mid-Atlantic region. They found that urbanization suppresses all three types of precipitation. Irrigation enhances non-convective and isolated deep convection precipitation, and its effects on mesoscale convective systems (MCS) depends on whether an MCS formed locally or remotely.

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.

New report finds that carbon capture and storage in California can concurrently serve local communities, the environment and the economy

A new report co-authored by George Peridas of the Lawrence Livermore National Laboratory (LLNL) and Benjamin Grove of the Clean Air Task Force examines the economic viability of carbon capture and storage (CCS) projects in California and finds that several classes of projects are viable today.

Firsthand fieldwork: ORNL scientists establish monitoring in at-risk coastal ecosystem

As a biogeochemist at the Department of Energy’s Oak Ridge National Laboratory, Matthew Berens studies how carbon, nutrients and minerals move through water and soil. In this firsthand account, Berens describes recent fieldwork in Louisiana with colleagues to better understand coastal ecosystems.

Expert available to discuss new report that puts globe on course for breaching benchmark high temperature

A new report from the World Meteorological Organization (WMO) shows that the world’s average temperature could breach a record 1.5 Celsius of warming compared to pre-Industrial Revolution levels. News reports call the WMO announcement a critical warning of an average world temperature limit in the face of climate. Researchers indicate the threshold could be broken as early as 2027.

A Better Understanding of Gas Exchange Between the Atmosphere and Ocean Can Improve Global Climate Models

The injection of bubbles from waves breaking in turbulent and cold high-latitude regions of the high seas is an underappreciated way in which atmospheric gases are transported into the interior ocean. An improved mechanistic understanding of gas exchange in high latitudes is important for several reasons, including to better constrain climate models that are used to predict changes in the ocean inventory of key gases like oxygen and carbon dioxide.

Climate change could cause “disaster” in the world’s oceans, say UC Irvine scientists

Irvine, Calif., Jan. 4, 2023 — Climate-driven heating of seawater is causing a slowdown of deep circulation patterns in the Atlantic and Southern oceans, according to University of California, Irvine Earth system scientists, and if this process continues, the ocean’s ability to remove carbon dioxide from the atmosphere will be severely limited, further exacerbating global warming.

High-Pressure Systems Favor Sea-Breeze Convection Over Southeastern Texas

In the summer, sea- and bay-breeze circulations are important drivers of the weather in southeastern Texas. This research used machine learning techniques to unpack how these circulations interact with larger-scale weather systems to affect how thunderstorms form in the Houston area. These insights are helping researchers focus their study of aerosol and cloud life cycle, aerosol-cloud interactions, and air quality during the TRACER field campaign in the Houston area in 2021 and 2022.
