More than 30 years ago, I began teaching courses on data analysis in the earth sciences. 20 years ago, I started thinking about writing textbooks. Now there are six textbooks and many different course formats for you. Here are the options for you:

The #Python and #MATLAB Recipes for Earth Sciences books are back in the top 100 at Springer Earth and Environment, the last two editions each. Thank you all for continuing to buy the books, even though they can usually be downloaded from university libraries!

Young people—as I was back then—do not really appreciate how quickly their valuable data, painstakingly created graphics, and carefully crafted texts can become unreadable. Here are a few thoughts on this and a recommendation:

Yesterday, I had a visit from an 11th grade class from a high school. I gave a talk on the climate tipping point 5,000 years ago and ancient Egypt, and had the students solve some problems using AI. It was alarming to hear that AI is not a topic covered in class. #geoscience

Potassium is a proxy for aridity in Chew Bahir, Ethiopia, due to the increasing illitization of smectites in a gradually drying lake. V Förster and colleagues have investigated this in detail—and last year we showed that this was even the case 379 kyr ago, as found at a core at 200 m. #geoscience
