Record freezing temperatures and global warming – let our experts explain

Jan 31, 2019

This week has seen temperatures drop to record lows. Across the mid-west, a polar vortex coupled with biting winds saw temperatures plunge below minus 50 degrees Fahrenheit.

As the word has been focusing on climate change, its causes and effects – this week stands as a stellar example of the impacts of global warming. Despite the tweets and trolls of prominent politicians somehow aligning a deep freeze as a counter argument for climate change the evidence is becoming more clear - with global warming, comes warnings far more worrisome.

Dr. Pamela Grothe, an Assistant Professor in the Department of Earth and Environmental Sciences at the University of Mary Washington, was recently quoted in the Guardian about how global warming is forecasting a grim future at the rate we are going.

“Warmer temperatures and associated lower oxygen levels in the ocean are sufficient to explain the observed extinctions we see in the fossil record”, she says.

“We are already seeing warming ocean temperatures and lower oxygen in many regions, currently affecting marine ecosystems. If we continue in the trajectory, we are on with current emission rates, this study highlights the potential that we may see similar rates of extinction in marine species as in the end of the Permian.”

And is this just the beginning?
What other extremes can we expect to see in our weather?
Can that trajectory Dr. Grothe reference be turned around or slowed down?
And what species are the most vulnerable and what ripple effect will that have on our oceans?

There are a lot of questions to be asked – and that’s where the experts from the University of Mary Washington can help.

Dr. Pamela Grothe is an assistant professor in the Department of Earth and Environmental Sciences as the University of Mary Washington. She recently completed a Ph.D. in the Paleoclimatology Lab at the Earth and Atmospheric Sciences department at Georgia Institute of Technology. Her current research involves a study of the central Pacific climate and El Niño Southern Oscillation (ENSO) variability over the past 6000 years through the analysis of coral fossil records.

As Congress Weighs the Future of Daylight Saving Time, a UMW Sleep Researcher Explains What Your Body Actually Goes Through

The House passed the Sunshine Protection Act on July 14, 2026, reviving the national debate over whether the U.S. should adopt permanent daylight saving time, return to permanent standard time, or keep the twice-yearly clock change altogether. The bill now heads to the Senate. At the University of Mary Washington, Dr. Hilary Stebbins, Associate Professor of Psychological Science, studies the chronobiology and sleep patterns of college students, research that can help inform exactly this debate: how does shifting the clock affect cognitive performance and behavior, no matter which system we land on? Dr. Hilary Stebbins is an Associate Professor in the Department of Psychological Science at the University of Mary Washington. She is an expert on sleep deprivation, circadian rhythms, and dopamine function, and how each affects cognitive performance and behavior. View her profile Stebbins doesn't take a side in the policy debate. Her focus is chronobiology, how sleep patterns and circadian rhythms affect college students' cognitive performance and behavior. But that science speaks directly to the choice lawmakers are weighing: any shift, whether it's permanent daylight saving time, permanent standard time, or sticking with the current system, creates a temporary mismatch between our internal clock and the outside world, and it takes the body time to catch up. "One of my past teams found that as people report higher levels of sleepiness, they show higher dopamine function and also have more difficulty controlling impulsive actions." — Dr. Hilary Stebbins, Associate Professor of Psychological Science, University of Mary Washington Stebbins leads a year-long undergraduate research team (PSYC 491/492) each year, and in 2018 a team of her students won the Virginia Association for Psychological Science's award for best undergraduate paper for their research on sleep deprivation.

What's in the Water? New Research Brings Weekly River Health Data to the Public

A recent article in the Fredericksburg Free Press highlighted a new University of Mary Washington initiative that is testing the Rappahannock River weekly for fecal coliform bacteria and sharing the results publicly. Led by Associate Professor of Earth and Environmental Science Tyler Frankel, the program aims to provide residents with accessible information before swimming, fishing, paddling, or otherwise enjoying one of the region's most important waterways. Dr. Tyler Frankel is an Assistant Professor in the Department of Earth and Environmental Sciences at the University of Mary Washington. He is an expert on ecotoxicology, specifically the impact of pharmaceutical, industrial waste products, & pesticides on aquatic wildlife. View his profile The project addresses a significant gap in environmental monitoring. While bacteria levels can change rapidly following rainfall and other environmental conditions, routine testing has historically been limited. Frankel and his student research team are collecting samples from five locations along the river and building a long-term database that can help identify contamination trends and potential pollution sources. The effort also provides valuable hands-on research opportunities for students while generating information with direct public health benefits. “There isn’t really a program that exists like that for the Rappahannock where the public can get access to weekly data sets.” — Tyler Frankel, Associate Professor of Earth and Environmental Science, University of Mary Washington The research focuses on fecal coliform bacteria, including E. coli, which can enter waterways through sewage, failing septic systems, agricultural runoff, pets, wildlife, and other sources. Elevated levels can pose health risks to people who come into contact with contaminated water, making timely and accessible monitoring an important tool for both recreation and environmental stewardship.
