The great global warming debate – our experts are being asked about the ethics behind controlling earth’s climate

Solar geoengineering - it’s a topic that has caused an ethical lightening storm in the science community. The concept is complex. Should the world take on the crisis of climate change by attempting to artificially attempting to cool the earth? It’s an idea that has the National Academies of Sciences, Engineering and Medicine seeking a billion dollars in the next five years to investigate the theory.


It’s a topic that is somewhat controversial, and journalists are looking to leading experts from across America for expert insight, opinion and perspective.



Prakash Kashwan, a political scientist at the University of Connecticut, said he felt the report could have better emphasized the seriousness of some concerns over others. Uncertainties about the impacts of solar geoengineering on global weather patterns have the potential to affect some regions of the world more severely than others, he pointed out.

Some experts have raised concerns about potential effects of geoengineering on monsoon rainfall in parts of Asia and Africa, he said. More than 2 billion people around the world rely on these rainfall patterns to support their water and agricultural needs. These kinds of issues should be given special weight, Kashwan suggested.

"Some uncertainties are much more highly consequential for the global society, and especially for the poor and vulnerable," he told E&E News.
Kashwan also reiterated concerns about potential political effects. While the report makes clear that geoengineering is not a substitute for climate mitigation, he suggests that this doesn't necessarily prevent policymakers from using it in that way.

"The problem is the extent to which researchers are really helpless in deciding how research is used in the political system," he said. "That part has yet to be fully appreciated."

Kashwan suggests that more dialogue might be warranted before funding a national research program, with greater input from both the international community and political experts who can weigh in on the ways that geoengineering research might affect political decisions.

Tick Population Surge Raises New Lyme Disease Concerns

A surge in tick activity across Connecticut is renewing concerns about Lyme disease, prompting experts to examine the environmental factors driving tick populations, the challenges of prevention, and the future role of vaccines. Recently reported by CT Community News and CTNewsJunkie, researchers are seeing unusually high numbers of ticks infected with the bacteria that causes Lyme disease, with infection rates reaching levels typically not observed until peak season. Experts point to a combination of environmental conditions, including a snowy winter that insulated overwintering ticks, milder seasonal temperatures, and continued residential expansion into wooded areas where ticks thrive. According to Dr. David Banach, an infectious disease specialist and epidemiologist at UConn Health, the increase in Lyme disease cases is influenced by multiple factors. While improved reporting may account for some of the rise, environmental conditions continue to play a significant role in the number of infections seen by clinicians each year. “Lyme disease is chronically underreported.” Dr. David Banach Dr. David Banach is an infectious diseases physician who leads UConn Health's Infection Prevention Program and serves as hospital epidemiologist. View his profile The article also explores ongoing efforts to develop new Lyme disease vaccines. Dr. Paulo Verardi, head of UConn's Department of Virology and Vaccinology, notes that vaccines could become an important tool in reducing disease risk, but cautions that vaccination alone will not solve the broader challenge posed by expanding tick populations and changing environmental conditions. Effective control, he argues, will require a combination of public education, land management, and efforts to reduce tick abundance. “To really control tickborne diseases, there needs to be more land management, public education and a drop in the overall tick population.” Dr. Paulo Verardi Dr. Paulo Verardi is a virologist who specializes in vaccine research and development. He is a Department Head and Associate Professor at UConn and a member of the Center of Excellence for Vaccine Research. View his profile As Lyme disease continues to spread across North America, understanding the intersection of climate, ecology, public health, and vaccine development is becoming increasingly important. Researchers are working to better understand why tick populations are expanding, how disease risk is changing, and what strategies can best protect people who live, work, and spend time outdoors.

Expert Insight: The ‘100 Deadly Days of Summer’

A recent article in the Hartford Courant examining a sudden increase in fatal crashes across Connecticut has transportation safety experts sounding the alarm as the busy summer travel season begins. The story featured Eric Jackson, executive director of the Connecticut Transportation Institute and director of the Connecticut Transportation Safety Research Center, who noted that 16 roadway fatalities were recorded in just nine days — a significant increase that quickly narrowed what had been a year-over-year decline in traffic deaths. Jackson points to a combination of warmer weather, longer days, increased travel, and more vulnerable road users on the road as factors that contribute to what safety professionals often call the "100 Deadly Days of Summer" between Memorial Day and Labor Day. He also warns that motorcycle fatalities may continue to rise as more riders return to the roads, particularly amid higher fuel prices. For journalists covering traffic safety, transportation trends, infrastructure, or public policy, Jackson offers valuable insight into the data, behaviors, and seasonal factors influencing roadway fatalities. The latest data released by the University of Connecticut Crash Repository — which tracks fatal crashes throughout the year — shows that 16 fatalities were reported on Connecticut’s roads between May 10 and May 19, when the numbers were last updated. That many fatal crashes in that short of a time span is a “huge” number and one that “we usually don’t see,” said Dr. Eric Jackson, a research professor at UConn. The overall number of traffic fatalities is still down across the state compared to the same time last year, but the gap has shrunk drastically in the last few weeks, according to Jackson, who serves as the executive director of the Connecticut Transportation Institute and the director of the Connecticut Transportation Safety Research Center. As of May 10, there were 64 traffic deaths reported in 2026 compared to 78 at the same time last year. The most recent data shows that 80 fatal crashes have now been reported so far this year, compared to 83 at the same time in 2025. One potential reason for the drastic uptick in fatalities could be the increased activity that goes along with warmer weather and longer days. “People are out and about more,” Jackson said. During the first several months of the year, cold weather and a number of winter storms could have contributed to keeping many people inside and slowing down those who did go out, Jackson speculated. “Snowstorms, huge weather events usually prevent fatalities because people aren’t driving as fast,” he said.   The trend is especially concerning as higher fuel prices have more people looking to motorcycles as a way to get around in better weather while reducing their fuel consumption. Nine riders have died in Connecticut in the past few weeks, leading some local news outlets to ask: Are high gas prices fueling a rise in deadly motorcycle crashes? Looking to know more?  We can help. Connect with Eric Jackson to discuss seasonal traffic safety trends, motorcycle safety, transportation data analysis, and strategies to reduce roadway fatalities.
