Juan Cole is worried about the safety of Tel Aviv

And the big threat is Global Warming!

Some of Israel’s Mediterranean coast is sufficiently low-lying, including the city of Tel Aviv, that the rising ocean levels that will be caused by global warming will submerge them over time. In past eras, an increase of 1 degree celsius translated into 10 to 20 meters increase in sea level. Even if we can hold our present increase to 3 degrees celsius through a crash global green energy program, that would be an increase of as much as 60 meters or 180 feet. Tel Aviv will certainly end up under water if humanity goes on spewing carbon dioxide into the air at this rate–not in this century, but over time. A majority of Israeli Jews live in and around Tel Aviv. Climate change is the real existential threat, not bluster from Iran.

I don't know about you, but I think the threat from Iran is a bit more pressing.
