Two thoughts on global warming:

1. Wind Energy. Wind turbines, which convert wind into energy, are hailed as a way of generating energy without harming the environment.

But I think we need that wind. I’m afraid we’re going to discover in ten or twenty or fifty years that the wind was part of the global ecosystem.

After putting a massive wind farm in, say, one of the plain states, will we have rain systems that no longer make their way across the country and instead stay put, causing massive flooding in the middle of the country and drought in the east?

2. Energy and Heat. Two of the biggest challenges facing us seem to be (a) not enough energy, and (b) the warming of the planet.

But heat is energy.

Can’t we solve both of these problems at the same time by using the extra heat on the planet for energy?

Haviv Rettig Gur has an essay in the Jerusalem Post in which claims:

Here’s a theory: Israeli society has a profoundly different and deeply moving way of defining the very notion of Jewishness. [read the essay...]

The essay sets the stage for his theory and expands on it. It’s well worth reading.

CNN has a video of the wall that’s well worth watching. (You have to put up with a brief commercial.)

From the Israel Antiquities Authority:

An Enormous 3,700 Year Old Fortification was Exposed in the City of David

The excavations are being conducted by the Israel Antiquities Authority in the Walls Around Jerusalem National Park and are underwritten by the Ir David Foundation.
