Maine frosh co-authors divestment column

Clara Belitiz, from Bowdoin, wrote this along with star science historian Naomi Oretz. I liked the new direction they took: Colleges and universities must divest because, essentially, denial is anti-intellectual and therefore anti-education.

And it is. Of course it is. How many years have we been warning about climate change. A hay-maker argument, that one.

Harvard's board is now outed as anti-science and anti-education! Time to resign, ladies and gentlemen. Give up and go home. Your services are no longer needed.


Article on CBA in the yUKe

We were discussing cost-benefit analysis in EC 2003 last night, specifically the problem that occurs for environmental (and other long-lived social) concerns when we discount future costs and benefits.

As it happens, I found an article in my morning paper about just such a difficulty in the UK.

Krugman calls for solar and wind

"So is the climate threat solved? Well, it should be. The science is solid; the technology is there; the economics look far more favorable than anyone expected. All that stands in the way of saving the planet is a combination of ignorance, prejudice and vested interests. What could go wrong? Oh, wait."

Jacob finds a flaw in ENSO

The Lean and Rind model data for 2014 has an as-yet undiagnosed flaw in the ENSO column, discovered by Jacob today.

Here's a patch to allow you to complete the assignment: Use the 2010 ENSO data in this spreadsheet here, except for the intervening years since 2010, for which use the 2014 data. be sure to add the timelags.

In the meantime, I'll try to see if I can figure out what happened with the 2014 data.

Update: Dawn found the problem. There are default-entries of "999.99"in places where the original data was missing. They're skewing the data averages. These need to be deleted and replaced with blank cells.
