Greek Mountain Snow Cover Declined by Nearly 60% Over 40 Years

Snow cover on the mountains of Greece has declined by nearly 60% over the last 40 years, according to a study by international researchers ^[1], ^[3].

This loss of snowfall threatens the primary water source for numerous local communities and fragile ecosystems. As winter snowpacks diminish, the natural reservoirs that sustain regions through drier months disappear, increasing the risk of water scarcity.

Detailed findings indicate that snow cover has decreased by approximately 58% ^[2]. Other data suggests the decline is nearly 60% ^[1], meaning more than half of the mountain snow cover has been lost over the four-decade period ^[1].

Scientists said the trend is driven by climate change, which has reduced the amount of winter snowfall. This shift disrupts the hydrological cycle of the Greek highlands. Without consistent snow accumulation, the slow release of meltwater during the spring and summer is compromised.

The researchers said the decline impacts both human populations and wildlife. Ecosystems that rely on specific moisture levels from melting snow are now facing more frequent periods of drought. Local communities that depend on this water for agriculture and drinking are particularly vulnerable to these changes.

This environmental shift reflects a broader pattern of warming in the Mediterranean region. The reduction in snow cover serves as a visible indicator of rising temperatures and changing precipitation patterns across the Greek landscape.
