Declining number of northern hemisphere land-surface frozen days under global warming and thinner snowpacks

Key Points

• Declining land-surface frozen days increases vulnerability of affected ecosystems to climate change.
• Frozen days decreased by up to 15 days in some regions between 2000 and 2020, demonstrating alarming trends.
• Analysis across multiple regions showed correlation between thinner snowpacks and reduced frozen days.
• This suggests that ongoing climate change may accelerate ecological impacts, necessitating further investigation.
