Corona slump macro update

The macroeconomic lessons offered by the C-virus pandemic continue. See below:



And, as predicted, an update on libertarian responses:

Unofficial first video for online GL4003, PS3003, and EC2123

I say this is the "unofficial" version because after making the video I realized I was wearing my scruffy old farm-work sweater with the hole in the elbow. But it's lambing season here on the farm and so that's how I dress. I was bottled feeding a lamb earlier and got lamb replacer all over a better sweater.

So I guess I'll have to make the video again before I post it "officially" to Canvas, wearing slightly tidier clothes!

But here you are, for all the diehards who know that the blog is still my go-to. I'm still experimenting with formats and applications, but this is an early preview of how I plan to teach online for the rest of the semester. I'm also testing how easy it is to post You-Tube to the blog, as well as how well students can access the materials via computer and/or cell phone.

I'm planning to use You Tube video-lectures much like this, as well as narrated PowerPoint slides, which will be available either in PowerPoint or YouTube versions, and various kinds of online-discussion/commentary for the participation portion of each class. The Canvas page for each course will have the official list of assignments, organized via the announcements page. If you have or get the Canvas ap for your phone, you'll be able to access all the YouTube materials on your phone, which should be a convenience to you.

Like I said, I'm just getting started here. I have the rest of the break to work this out. The official start date for the rest of the semester (week 10 through 15) is March 30th.

Watch this space for more to come, as well as via Canvas.

WAPO contrasts messaging on COVID 19

Scientists all around the world are watching with dismay the politicians get it wrong again and again. When will we learn this lesson?

Remember, folks: "Nature bats last" may be a slogan or even a bumper sticker, but it's also a fact. Humans like to convince themselves that they are all powerful creatures, but we don't have the last say.

PLIOMAX and other analogs

PLIOMAX: the international effort to determine the Pliocene sea level highstand, has its landing page linked below. This is an example of an effort to explore climate "analogs" in order to determine key parameters of global change in the next few decades and centuries. An analog might be a geological era or event that offers a good guide to the planet's behavior under similar conditions of forcing and coupled circulation.

You may remember that Hansen et al 2016 depended heavily on the Eemian analog for sea level rise and the future of the WAIS. Analogs stand in some contrast and/or tension with models, both GCMs and Ice Sheet Models. This was carefully expressed in Hansen et al 2016.

The video we watched is here, and there are a couple other good ones below.
