3 Things A Climate Scientist Learned From Jane Goodall
In a recent Forbes article, Marshall Shepherd reflects on three key lessons he has drawn from the life and work of Dr. Jane Goodall. Shepherd frames Goodall’s legacy—spanning primatology, conservation, and public engagement—as deeply instructive for climate scientists and environmental advocates. He argues that her methods and mindset have more to teach than simply how to observe nature; they speak to how we engage with the world.
First, Shepherd highlights immersion: Goodall’s decades of patient observation in the Tanzanian forests demonstrates the power of being physically—and emotionally—present to truly learn from ecosystems. For Shepherd, climate science must go beyond remote data collection: getting into the field and understanding local realities matters. Second, he emphasizes patience. Goodall’s willingness to wait, sometimes for years, for breakthroughs in understanding primate behavior offers a lesson for climate researchers, whose progress may unfold over decades. Third, he admires her tenacity—a commitment sustained over a lifetime, even under adversity. Shepherd suggests that tackling climate change requires that same kind of enduring resolve, especially when public attention or funding waxes and wanes.
Through these reflections, Shepherd presents Goodall not just as an icon of conservation but as a model for scientific humility and perseverance. He invites readers to see the parallels between animal behavior research and climate work—and to adopt practices of listening, patience, and resolve in confronting our planet’s changing trajectory.

Experts in the Media: Hurricane Season Isn’t Shutdown. A Busy Week Looms For Meteorologists
When you think hurricane season is winding down, think again. Just as many people begin to relax after a stretch of calm weather, the atmosphere often has other plans. Meteorologists are warning that even as we head deeper into October, the tropics are far from done stirring. The “off-season,” as Dr. Marshall Shepherd puts it, can be one of the most deceptive times of year—when attention fades but nature remains restless.
Dr. J. Marshall Shepherd is a leading international weather-climate expert and is the Georgia Athletic Association Distinguished Professor of Geography and Atmospheric Sciences at the University of Georgia. Dr. Shepherd was the 2013 President of American Meteorological Society (AMS), the nation’s largest and oldest professional/science society in the atmospheric and related sciences. View his profile here In his recent Forbes article, Shepherd, a leading atmospheric scientist and former president of the American Meteorological Society, reminds readers that the Atlantic hurricane season doesn’t have an on-off switch. While it may appear to be slowing, meteorologists are bracing for a busy week ahead as multiple weather systems continue to develop. He explains that this year’s pattern demonstrates how tropical activity often ebbs and flows, and a lull in storms doesn’t mean the threat has passed.
Shepherd highlights how experts are closely watching sea-surface temperatures, wind shear, and atmospheric moisture—factors that can quickly transform calm seas into cyclone breeding grounds. Despite the calendar inching toward November, he warns that conditions remain ripe for sudden storm formation.
Ultimately, Shepherd’s message is one of preparedness and respect for nature’s unpredictability. Even when the radar looks clear, the tropics can still surprise us. His call to stay alert is a timely reminder that meteorology is not about predicting the past—it’s about anticipating the next twist in the weather’s unfolding story.

2 Hour Lead Time For Tornadoes Is Possible But Do We Want It?
Forbes online
2025-05-08
We are in the peak of the U.S. severe weather season, and tornadic storms have been particularly prevalent this season. During my tenure in the meteorological field, one of the “holy grail” research challenges has been to improve tornado warning lead times. A NOAA research program has demonstrated that we may be able to give up to two hours of advance warning of a tornado. Here’s how it is possible as well as some thoughts on whether we want it.
Weather apps are a staple of life these days. Over the years, I have written several commentaries on their pros and cons. From my perspective as a meteorologist, the “cons” often outweigh the “pros,” but a new app is generating significant buzz. Here’s why.

“We’re all talking about how much more it’s ramped up,” said Marshall Shepherd, who is the director of the University of Georgia’s Atmospheric Sciences Program and a former president of the American Meteorological Society. There has been “a palpable difference in tone and aggression toward people in my field,” he said.
As Disinformation Swirls, Meteorologists Are Facing Threats

Climate change skeptics have long accused weather forecasters of pushing what they view as a “climate change agenda,” Shepherd said. But things took an ugly turn this month when conspiracy theorists denounced scientists for covering up a supposed government plot to engineer the weather and send storms to Florida and North Carolina. “In the past, the harassment was over in a fringe element,” Shepherd, a former president of the American Meteorological Society, said in an interview with Yale Environment 360. “In this last episode, it was bit more mainstream.”
The Bullying Of Meteorologists During Hurricanes Helene And Milton
Forbes online
2024-10-12
Bullying of meteorologists is sadly not new. Women in the TV sector of our field deal with misogynistic comments about their attire, hair or looks. Broadcasters face backlash if they interrupt a televised golf tournament or movie to warn the public about impending weather threats. The weather community also faces constant scrutiny about the accuracy of forecasts, though most of those narratives are based on perception rather than facts. Climate scientists are also targeted by special interests, trolls and bots. During Hurricanes Helene and Milton, I noticed an even darker tone to the bullying.
I’m an atmospheric scientist. People do not control hurricanes.
AJC online
2024-10-11
Meteorological fall starts on the first of September. Fall is one of my favorite times of year. It brings crisp air and college football (Go Dawgs!).
The big negative is that it also represents the most active part of the Atlantic hurricane season. Though hurricane season kicks off on June 1, activity usually ramps up in August and peaks in the second week of September. Complex physics related to specific heat explain the lag between the start of the season and its peak, but I won’t bore you with a physics lesson.

Sometimes people think a warming climate means more storms, but that’s not exactly true, climate scientist James Marshall Shepherd, a professor at the University of Georgia and director of its Atmospheric Sciences Program, tells Popular Mechanics. Instead, the storms we do experience will be stronger, creating more dire episodes like the one in Libya. Marshall’s research focuses on using remote sensing and modeling to study climate and extreme weather risks.

Experiencing a single disaster - a hurricane, tornado, flood, severe winter storm, or a global pandemic - can wreak havoc on the lives and livelihoods of individuals, families, communities and entire regions. For many people who live in communities in the U.S. Gulf of Mexico region, the reality of disaster is starker. Endemic socioeconomic and health disparities have made many living in Gulf of Mexico communities particularly vulnerable to the effects of weather-climate hazards.
Impacts of Urbanization on Precipitation and Storms: Physical Insights and Vulnerabilities
Climate Vulnerability
2013-03-15
Climate change has been the subject of thousands of books and magazines, scientific journals, and newspaper articles daily. It’s a subject that can be very political and emotional, often blurring the lines between fact and fiction. The vast majority of research, studies, projections and recommendations tend to focus on the human influence on climate change and global warming as the result of CO2 emissions, often to the exclusion of other threats that include population growth and the stress placed on energy sources due to emerging global affluence.

Establish your scientific credentials, and then allow everything to flow from that expertise. So advised my valuable mentor, Dr. Warren Washington, a recipient of the Presidential Medal of Science who resides on the Mount Rushmore of my career influences, when I was a young scholar. I sensed concern in Dr. Washington’s tone. As a fellow African American scientist, Dr. Washington understood the lack of representation within the atmospheric sciences.
Global scale assessment of urban precipitation anomalies
Proc. of National Acad. of Sciences
2024-09-29
Urbanization has accelerated dramatically across the world over the past decades. Urban influence on surface temperatures is now being considered as a correction term in climatological datasets. Although prior research has investigated urban influences on precipitation for specific cities or selected thunderstorm cases, a comprehensive examination of urban precipitation anomalies on a global scale remains limited. This research is a global analysis of urban precipitation anomalies for over one thousand cities worldwide.
The Curious Relationship Between COVID-19 Lockdowns and Urban Heat Islands
Geophysical Research Letters
2022-03-26
The COVID-19 pandemic has been a life-altering shock to society. However, there have been serendipitous outcomes from the associated lockdowns ranging from improved air quality to reductions in carbon emissions. Liu et al. (2022, https://doi.org/10.1029/2021GL096842) revealed that even the magnitude of the heat islands in Chinese cities were reduced due to a decline in human activities and their associated anthropogenic contributions. These surprising findings have significant implications for understanding intersections among climate, health, energy, urban planning, transportation, and infrastructure.
A global spatiotemporal analysis of inland tropical cyclone maintenance or intensification
International Journal of Climatology
2014-02-01
Forecasting tropical cyclone ( TC) intensity changes over land is complicated by interactions of various surface and atmospheric features. Due to generally unfavorable conditions, many TCs weaken and decay soon after landfall. In some cases, TCs may also transition to extratropical cyclones (ETs). Despite the absence of oceanic forcing, a number of TCs have been observed to maintain or increase strength inland, termed 'tropical cyclone maintenance or intensification' (TCMIs). This study identifies the environments and characteristic features of TCMIs and explores physical processes that may help to produce an atmosphere conducive for tropical systems.

Analysis of a unique satellite precipitation dataset coupled with an extensive database of storm tracks are used to develop a parameter called the “millimeter-day (MD).” MD analysis in 4 mini-basins near coastal southeastern United States reveals that September and October account for the largest number of extreme rainfall days (e.g. “wet millimeter-days” or MD > 0) during the 1998–2006 Atlantic hurricane seasons.
A Review of Current Investigations of Urban-Induced Rainfall and Recommendations for the Future
Earth Interactions
2005-07-01
Precipitation is a key link in the global water cycle and a proxy for changing climate; therefore, proper assessment of the urban environment’s impact on precipitation (land use, aerosols, thermal properties) will be increasingly important in ongoing climate diagnostics and prediction, Global Water and Energy Cycle (GWEC) analysis and modeling, weather forecasting, freshwater resource management, urban planning–design, and land–atmosphere–ocean interface processes. These facts are particularly critical if current projections for global urban growth are accurate.
