Patterns and drivers of Holocene moisture variability in mid-latitude eastern North America - Nature Communications Thousands of years long droughts have occurred in eastern North America during the Holocene (past 12,000 years).

New paper out! "Patterns and drivers of Holocene moisture variability in mid-latitude eastern North America." Some of the best data-model agreements yet... the melting of ice sheets and changes in insolation were major drivers of changing rainfall patterns. www.nature.com/articles/s41...

Paleorecords Reveal Biological Mechanisms Crucial for Reliable Species Range Shift Projections Amid Rapid Climate Change Climate change has created an urgent need for reliable projections of species distributions. By hindcasting forest tree range shifts across Europe over the last 12,000 years, we show that process-exp...

Ever wondered how reliable species distribution models (SDMs) are in the face of climate change compared to more mechanistic approaches? We did too, and our results are now published in Ecology Letters ⏬

See that big pine? You own that tree, and billions of other trees on public lands. The trump kleptocracy will overharvest, mismanage, and steal our forests. Our land needs care from highly trained people, but they are being fired. We have to stop them. We need to force congress to act on our behalf.

Higher ed must resist authoritarian rule. It's the mission. Trying to make your institution a smaller target isn’t going to work.

Establishing the President's Make America Healthy Again Commission By the authority vested in me as President by the Constitution and the laws of the United States of America, itΒ isΒ hereby ordered: Section 1.

This commission statement refers to people with Autism, ADHD, asthma, auto-immune disease, and chronic illness as a β€œdire threat to the American people and our way of life”.

This is a manifesto against disability.

This is the language of eugenics.

5 Calls Spend 5 minutes. Make 5 calls. Make your voice heard.

We’ve heard a lot in the US that we should call our representatives to oppose a wide array of policies from our new fascist regime.

5 calls, which collates contact information and generates scripts for your zip code, makes it easy for anyone to take at least this small action regularly

Worried about losing access to US federal data that may go off-line, or already is? You’re not aloneβ€”but duplication isn’t the answer.

Many ongoing efforts have already archived key datasets and many more are ongoing. Check out these existing resources and, if you can, support their work. 🧡

Refining past climate records with wood anatomy Nature Reviews Earth & Environment - Julie Edwards explains how quantitative wood anatomy helps refine records of past climate.

I got to write a 'Tools of the Trade’ article about quantitative wood anatomy a little bit ago. Check it out for an accessible summary of how measuring wood cells is improving our understanding of past climate!

No problem! The good news is that that type of tree does not have damage to its important tissues from that happening so it is probably still healthy!
