Yesterday, I mentioned climate change visualizer extraordinaire Zack Labe. As delineated then, he’s a PhD student at U.C. – Irvine in the Earth Systems Science department. He’s producing some really excellent #dataviz on climate change. Today, I’d like to share a short exchange I had with Zack about his work. 1) Please give Mountain Beltway readers a sense of your background, leading up to what you’re working on …

The amount of sea ice on planet Earth is much, much lower than ever recorded at this time of year. Will this anomaly turn out to be a relatively minor “weather” event? Or is this what a sea ice tipping point looks like?

I have known for a long time about a diamictite in the latest Devonian part of the Appalachian stratigraphic sequence, since it is exposed in the lowermost part of the section (western end of the outcrop) at Sideling Hill, Maryland. When I led field trips there, I talked students through the multiple possible origins for diamictites (sedimentary rocks that are poorly sorted, with significantly “outsized” clasts “floating” in a finer-grained …

This is probably the last week our planet’s atmosphere will have less than 400 parts per million of carbon dioxide. When are we going to stop letting this heat-trapping waste gas pile up in our home?

Please. Please. Please. Please stop conflating weather and climate. It is cold today, yes, and that’s a big deal. But it doesn’t influence any scientific conclusion about climate change, one way or the other. Today’s cold temperatures are a weather event. It’s distinctive, but short-lived. Climate is a long-term trend: many years of weather events. It’s not something you can point to on a single day, and say “ha!” Climate …

I finished Simon Winchester’s book Atlantic the other day. I consumed the audiobook version (this is one major positive aspect to my long commute: plenty of listening time), which was pleasantly read by Winchester himself. He’s got a good accent and a nice way of speaking – I recommend that medium. Atlantic is a book about the Atlantic Ocean. It’s set up to cover the vast sweep of Atlantic history, …

I finished reading Barbara Kingsolver’s new novel Flight Behavior over the weekend. It’s certainly cut from the same cloth as Kingsolver’s other work. If you liked Prodigal Summer and her many Arizona novels, you’ll probably like this one, too. Similarities include: beautiful writing, a focus on the relationships women have to their families, friends, and strangers, and the powerful insights we can gain by associating with nature. What sets it …

One of the ~350 or so blogs I subscribe to is Arctic Sea Ice by Neven. Today, he put up a post highlighting new daily data from IARC-JAXA, a collaboration between the International Arctic Research Center (IARC) at the University of Alaska-Fairbanks and the Japan Aerospace Exploration Agency (JAXA). Check it out. Here’s a couple of things I was struck by: The annual variation between summer and winter ice cover …
