Happy New Year to my favorite pandemic online-teaching student email from two years ago, when my cats were essentially the mascot for all my classes.

For reference, this is the video he sent me:

To peer into Earth's deep time, meet a hardy mineral known as the Time Lord - Geologists rely on tiny crystals of the mineral zircon to understand the timing of key events in Earth's early days, like the rising of continents and the emergence of oceans. #npr

I seem to remember a paper a few years ago showing that if a student asks the first question after a lecture, there tends to be more student engagement with the speaker than if a faculty member asks the first question...but I can't find the original source. Does anyone have the citation?

When people say global warming can lead to "worse" winter extremes what do they mean by "worse"?

I-colder cold extreme?
II - more frequent cold extremes?
III - colder AND more frequent cold extremes?

My null hypothesis would be of a mean shift

IV - warmer and less frequent cold extremes

It's easy to inject sulfur particles to reflect sunlight to cool the Earth.

It's not easy to know whether it can be done safely and effectively.

Definitely not easy to ensure govts & people are ready for it.

A startup has done it anyway 🤦


This bombshell from @jtemple points out so many things that are wrong about Make Sunsets, a startup that claims to have released sulfur particles into the atmosphere for solar geoengineering and is trying to sell “cooling credits” on its website.

Our latest #DEI paper in European Science Editing, Pourret et al. "Gender balance and geographical diversity in editorial boards of Geochimica et Cosmochimica Acta and Chemical Geology"

The internet never forgets.

You on the other hand have to remember if the fleeting idea you had is on google drive or dropbox or in a slack channel or in a text to your friend or did you tweet it a year ago....

New paper in Paleo2:

A Pliocene precipitation isotope proxy-model comparison assessing the hydrological fingerprints of sea surface temperature gradients

Led by Scott Knapp and Natalie Burls, proxy data compiled by Sarah Feakins

One key takeaway for me is we need more isotopic records of Pliocene hydroclimate, from across the world!

I’m fairly new on #Mastodon but one thing I’ve learned is that unlike Twitter, starring ⭐️ a post doesn’t make it more likely to be seen since there’s no algorithm. Reblogging 🔁 is the way to get more people to see the post.

Starring is more like a digital hug and is still welcome.


@atthenius I'll come down anytime you'll have me!! would love to chat science. We are hoping to generate some Miocene data in the next few years so this might be a good time!

Hello world! Happy to be here, tweeting (whoops, tooting!) about the science we do in my group. here's our latest paper on the Pliocene North American Monsoon.

This is part of a broader project to study past reorganizations of tropical and subtropical hydroclimate during warm climate intervals
