If you’ve ever compared the (lack of) clear air in Israel today with scenes in older photographs, you may not be surprised that one factor affecting Israel’s skies today is pollution arriving from other countries. From Haaretz:

Scientists have been studying air particles arriving in Israel for years, and it is known that pollution can move long distances. But only in recent years has a precise analysis been made of the pollution and its origins.
The meteorologic data indicates that for two thirds of the days of the year, air currents arrive from Western and Eastern Europe, and for more than one-fifth of the year, air currents arrive from Saudi Arabia, Jordan and North Africa.
