Before you set a hashtag for your course or have students blog, think FERPA

Are you going to require that your students post on a public blog this semester?  Will you be creating a Facebook page for your class and asking students to post on it?  Will you have students post selfies on Twitter with a course hashtag?  For those instructors that use social media with their students and courses, this could be the most important tweet you read all year:   Is your …

Crazy Summer Weather pattern Is About To Flip

The summer of 2014 has been unusually mild in the Midwest and portions of the East, and brutally hot and dry in the West. The heat and drought in the NW corner of North America has led to raging forest fires that have spread dense smoke over the northeast and across the Atlantic to France, and the drought in California has reached the worst possible level: exceptional drought. Mother Nature is …

Devising a policy on technology in the classroom? Ask your students, David Gooblar writes in @chroniclevitae. http://t.co/O2DBAMudN1 — Chronicle (@chronicle) January 23, 2014 For those of us heading back to the classroom this fall, we are thinking about what to do in our classes, and how to keep our students engaged during the 50 minutes we have them three times week – and by “engaged,” I mean keeping students connected …

Will Oysters Share the Same Fate as the Wicked Witch of the West?

Oceans. You don’t have to live on the East or West coasts to understand and appreciate the appeal of the oceans. From long walks on the beach to collecting seashells, images of the oceans proliferate our media, romantic literary epics, and vacation planning. However, that is all changing as our oceans increase in acidity. To put it simply, like the wicked witch of west, invertebrates like oysters, mussels, and other shelled creatures are “melting”

Snow,Cold, and Drought: The Coming Winter Might Be Brutal

I’ve spent the weekend looking at how the coming winter may turn out, and before I go any farther, let me say that long-range forecasts can turn out to be horribly wrong. Let me repeat that: long-range forecasts can turn out to be horribly wrong. That said, there are some fascinating indications that the Eastern and Southeastern U.S. may be in for a cold and wet/icy winter, while the drought in …

How Weather and Climate Models Work- or Why Meteorologists Learn Calculus

Numerical weather models have come light years over the  last 30 years, and despite what you may think, they make it possible to make very accurate weather forecasts for as much as 5-7 days into the future possible. Have you ever wondered just how they work? It’s not something that you can cover in a few paragraphs, but it is not all that hard to get a basic understanding of …

This Is Why Canada and The West Are Burning

NASA posted this map of the temperature anomalies over North America for July, and you can easily see why we there is so much wildfire activity in the U.S. West and Canada North.

Worried about Speaking in Public? Try Toastmasters. Really.

That’s right, Toastmasters, the outfit with the retro name that seems to promise insurance salesmen who shake your hand too hard, like that guy in the movie Groundhog Day who keeps pestering Bill Murray. “It’s Ned! NED RYERSON!”

Yes, I was dubious, too.

But then la few weeks ago I actually went to a meeting…

Dense wildfire smoke (from forest fires in Canada) has once again moved into the NE U.S. The smoke is bringing a hazy sky this evening to the Eastern Great Lakes, and across NY and into Maryland,Virginia, and Delaware.

Dysfunction Junction (Part 2)

Several weeks ago I wrote a piece on the background of the U.S. congressional appropriations process, outlining the procedure through which the Federal government is funded. Progress to Date: The Senate has begun work on several appropriations bills, but as of today none have been passed by the full Senate. The Commerce-Justice-Science (CJS) appropriations bill which funds NASA, NIST, NOAA, NSF, and the White House’s Office of Science and Technology was passed by the full Appropriations committee in June with broad bipartisan support, and appeared destined for the president’s desk.

Sea-level spikes can harm beaches worse than hurricane

Unforeseen, short-term increases in sea level caused by strong winds, pressure changes and fluctuating ocean currents can cause more damage to beaches on the East Coast over the course of a year than a powerful hurricane making landfall, according to a new study. The new research suggests that these sea-level anomalies could be more of a threat to coastal homes and businesses than previously thought, and could become higher and more frequent as a result of climate change.

How Nuclear Waste Disposal Can Help Us Understand Debate Over Fracking

Remember when shale gas was the answer to our energy woes? It was touted as a cheap and plentiful energy source that would reduce our dependence on foreign oil. Industry experts promised jobs, depressed local economies looked to get boosts; with so much good to be had, extracting natural gas from shale looked to be a no-brainer.
