Vermont, once considered a climate refuge, is now facing increasing challenges from climate change, according to a new state assessment released in 2025. The report highlights a range of accelerating climate impacts that are reshaping the state’s environment, infrastructure, and economy.

Previously, Vermont was viewed as relatively resilient to climate-related threats such as wildfires, hurricanes, and droughts affecting other parts of the United States. In 2017, the Environmental Protection Agency identified Vermont as one of the most climate-resilient states, and a 2020 analysis found that several of its counties ranked among the least vulnerable nationally. At the time, then-Governor Phil Scott expressed cautious optimism about potential benefits, including a longer growing season.

However, recent data paints a more complex and concerning picture. The 2025 Vermont Climate Assessment reports a significant rise in average annual temperatures—up 3.6 degrees Fahrenheit since 1900—and an increase in yearly precipitation by 7.3 inches. Winters have warmed faster than summers, leading to a notable decline in snowfall levels, which is placing pressure on the ski industry that increasingly depends on artificial snowmaking.

The state has experienced three consecutive summers of heavy rainfall, including catastrophic floods in 2023 and 2024 that caused over $1 billion in damage. These floods submerged towns, destroyed homes and businesses, and exposed vulnerabilities in Vermont’s aging infrastructure, such as dams and utility poles. At the same time, 2025 saw the state’s most severe drought in 25 years, illustrating a pattern of "climate whiplash" marked by rapid swings between extreme wet and dry conditions.

The consequences extend beyond infrastructure. Public health and ecosystems are being impacted; the report notes a fourfold increase in Lyme disease cases over the past decade, linked to warming temperatures that favor tick populations. Additionally, rising heat, wildfire smoke, and humidity complicate efforts to maintain healthy indoor environments, particularly for the one-third of Vermonters without air conditioning.

Agriculture faces mixed prospects. While the longer growing season could offer opportunities for some crops, increased variability and extreme weather events present ongoing risks. Outdoor recreation industries, essential to the state’s economy, are also at risk due to these shifting climate patterns.

The assessment does not propose specific policy actions but emphasizes the importance of using the data to guide adaptation and mitigation efforts. Jon Copans, executive director of the Foundation for a Resilient Montpelier, emphasized the urgency of resilience projects across Vermont communities to address these evolving threats.

Expert voices, including Jessica Balerna, a postdoctoral fellow at the University of Vermont’s Gund Institute, highlight that Vermont’s rural character, aging population, and infrastructure contribute to its climate vulnerability. The state’s experience now challenges earlier assumptions that it could serve as a safe harbor from the broader consequences of climate change.
