This is just not true. Winters in Greece have warmed up (less than here) and snow frequency has decreased significantly esp in Northern Greece.
However more localised heavy snowfalls have increased in Athens and some Aegean islands (they have a version of lake effect snow) over the last 30 years mainly due to a more prominent Azores high.
Before the Internet era people here didn't know how often it snows in Greece as they only go there during the hot summer season.
And speaking of this, the summers there have trended significantly hotter over the last 30 years (1-1.5C).
Apologies for the off-topic.
