DOE climate report response form We are collecting names to assemble a writing team to respond to the DOE climate working group report. If you'd like to contribute, enter your info below. At this point, there is no guarantee what we'll do (if anything), but we want to keep our options open by collecting names. If you have any further questions, feel free to email me. We are primarily looking for Ph.D. scientists at universities or government labs in appropriate fields. I realize that this will exclude some qualified people and I apologize, but we felt this was necessary for a variety of reasons.

🚨 If you're interested in working on a coordinated response to the DOE climate report, please enter your info on this google form 🚨

Please RT this so as many people see it as possible.

15 sources of wildfire smoke forecasts for North America » Yale Climate Connections Forecasting wildfire smoke is hard. We review the best tools to help you predict when unhealthful levels of smoke are coming.

We now live in the Pyrocene, a proposed new geologic epoch of fire activity brought about by human-caused climate change. Living in the Pyrocene means a new reality: knowing what the latest wildfire smoke forecasts are, in order to plan your outdoor activities. I review the best tools to do so:

New paper out in Global Change Biology 🤩

We built the first soil carbon model that includes microbial eco-evolution using game theory — and found that adaptation could nearly double global soil carbon loss by 2100. Here is how👇(1/7)

The Silent Foundry Beneath the Forest: How Deep Roots Accelerate Mountain Weathering The needles of Douglas-fir catch the weak afternoon sun, but the real story begins far below, where root tips rummage through shale the way prospectors pan river silt—patiently, relentlessly.

Soil organic carbon is at risk in a large part of European agricultural 🧑‍🌾🌱🌿 land. The topsoil organic carbon pool is at high risk in 43 to 83 million hectares of EU and UK🧪🔬. A new study published by @naturecomms.bsky.social

Great joint effort involving 4 doctoral researchers in the lab!

Our new paper shows that soil cation exchange can delay CO₂ removal from enhanced weathering by years to decades. Lag varies by soil, climate, and land use—longest in high-CEC regions like the Corn Belt. Big implications for MRV, credit timing, and deployment strategy. Timing matters! 🪨🌾

This is horrible news for anyone who breathes air or drinks water. EPA's research arm works to identify emerging pollution hazards. Ask yourself, who would be against that...🤔🤔🤔

Too bad there is a pay wall on that one because it is another story about the disasters of AI that need to be told....but in Australia is it looking like increased power demand will be met by coal and not renewables?

There’s a Race to Power the Future. China Is Pulling Away. (Gift Article) Beijing is selling clean energy to the world, Washington is pushing oil and gas. Both are driven by national security.

China is pulling away in the race to power the future.

Question for soil microbiologists that came up in a meeting today: do we consider the deposition of spores "colonization", or only the occurrence/growth of germinated/vegetative cells?

Congratulations!

Considering the Federal situation, campuses are encouraging labs to enter partnerships with industry.

A plant breeding company reached out to see if my lab could rate their plant lines for their resistance to Ralstonia. I said "maybe, but these assays require personnel time and materials"
