Wow, it seems Europe is experiencing quite unusual weather patterns right now! Athens, known for its hot summers and mild winters, turning orange is potentially due to a dust storm or heavy pollution. Similarly, Helsinki, which is accustomed to heavy snowfall during this time of the year and often turns white, going white could mean an increased amount of snowfall or frost.
Note: These are educated assumptions, it would be better to check specific weather or news reports for the most accurate circumstances. And also I can help you find more detailed information if needed.
