This will be huge, if they can work out the manufacturing issue.

The Recycling Religion
Thoughts from John Tierney:
I realize that true believers don’t need rational reasons for their religion, but it would be nice to see a little soul-searching in regard to some stats in the article: To offset the greenhouse impact of one passenger’s round-trip flight between New York and London, you’d have to recycle roughly 40,000 plastic bottles, assuming you fly coach. If you sit in the front of the plane, it’s more like 100,000 bottles — and you have to make sure not to rinse any of them with hot water, because that little extra energy could more than cancel out any greenhouse benefit of your labors.
They were told there would be no math.
El Faro
Why did it head into Joaquin?
It does seem like poor judgment. Back in ’98, a month after Patricia and I took a cruise on it (and a couple months before she started a job in Puerto Rico), the Fantome went down in Hurricane Mitch, with all hands (though they’d dropped off non-essential crew in Belize City). It was kind of shocking, because we just had met many of them. They were trying to take the ship out to sea, to keep it from getting battered in the harbor. But hurricane tracking wasn’t as good back then. They thought it was going to head toward the Yucatan, and so they headed southeast, but the storm took a turn and they went right into the heart of it.
Ironically, a Honduran woman who was washed out to sea in the flooding was rescued, after she was found holding on to some floating debris by aircraft patrols looking for debris or survivors from the ship. If it hadn’t gone down she probably would have died.
[Monday-morning update]
Sad, but not surprising news. The Coast Guard is declaring the ship sunk. That’s pretty much a foregone conclusion when you’re in a major hurricane with no propulsion.
Obama’s Mass-Shooting Claims
Politifact: Mostly false.
Considering the source, that has to hurt.

These are the kinds of policies that made the Depression Great.

The Riddle Of Obama
Thoughts from Neo-neocon:
Obama is here to punish America for its sins, and he’s been very successful at that. That the left and many liberals continue to love him, continue to support him, is a puzzlement to many people. But why wouldn’t those who have been successfully taught that America is a great evil in the world—birthed in evil, steeped in evil, and empowered by evil; especially racial evil but also countless other evils big and small—applaud his efforts?
Yup.
Plus, thoughts from a few days ago about facing the truth about the president.
