Last winter’s ski season in New England was notably different, with significant snowfall despite rising temperatures affecting the region over the past decade. Skiers are experiencing later seasons and skiing in less-than-ideal conditions. Ice sports are also suffering, with lakes like Lake Champlain seeing fewer freeze-over occurrences since 2020 compared to past decades.
The decline in snow and ice is part of a larger issue related to Earth’s albedo—a measure of how much sunlight a surface reflects. NASA has reported a steady decrease in Earth’s albedo from 29.3% in 2003 to less than 28.7% by the end of 2025. Snow and ice, which have high albedo, help reflect sunlight and act as a protective barrier against solar radiation. The loss of these reflective surfaces means more absorption of solar energy, contributing to further warming.
For example, studies show a 36% drop in snowy days in Southern New England from 2021 to 2025 compared to 2001 to 2005. As snow disappears, the buffering effect it has on watersheds also diminishes, leading to inconsistent spring thaws and increased winter flooding and summer droughts.
This darkening of the planet poses threats not only to the economy but also to national security, as reduced ice levels in the Arctic change geopolitical dynamics. However, there is hope: every reduction in carbon emissions contributes to a brighter future. New England is making strides toward sustainability, with states committing to net-zero emissions and the launch of clean energy projects. As Earth Day approaches, embracing these efforts can help envision a brighter, more sustainable world.
