Christmas Cheer
As you may have noticed, things have been quiet here at Beyond Green. Mrs. Beyond Green and I, along with the Beyond Greenlets, have been busy with this and that. But on this Christmas Eve, I thought I'd share with you a heart-to-heart I had tonight with my visiting sister-in-law who's a paleoclimatologist. We were talking, as you might expect on a festive night like this, about deep ocean currents - her specialty, as it happens.

She assured me that, no, Virginia, the oceans will not start spewing poison gas any time soon. In fact, the doomsday scenario I was ruminating upon recently isn't really possible except on a geologic timescale, i.e. millions of years. While it's true that the deep ocean currents will be affected by climate change, it will be a result of the change in salinity due to melting glaciers rather than warmer ocean water per se. That's sure to cause alterations in the climate, but at least on the "human" timescale of the next few thousand years, won't be enough to cause the oceans to go anoxic. And it won't cause Europe to plunge into an instant ice age the day after tomorrow, either. All of which I found rather cheering.

With that thought to warm you, I wish everyone Happy Holidays. Posting will be light over the next week. So keep an eye on things for me.
