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 story of deep drilling in the Chew Bahir Basin in southern Ethiopia continues. After drilling to a depth of 300 m in 2014, taking us 620 thousand years back in climate history, we now plan to go much deeper. There will be also an online hub in at @unipotsdam.bsky.social for you to participate!

AI changed everything, also the way of collecting, processing and presenting geoscientific information. Having published two editions of a book on the topic, it was time for a change. And two new books.

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
