Carbon Capture Has a Hard Limit and Wind Power’s Out
Plans for carbon capture and sequestration have an effective limit of 0.7 degrees. So mitigation is perpetually proven to be the best green energy strategy.

👏 Thrilled to see this paper online @pnas.org. One of the biggest mysteries in marine science is how much terrestrial organic matter is in the oceanic carbon pool. 🤔 We address this question here! Read the paper 👉 www.pnas.org/doi/abs/10.1... 🧵1/3

Logging changes the composition of the organic matter in nearby streams, making the organic matter more reactive. According to the authors, these changes are enough to flip logging from a carbon-sink to carbon-neutral or even a carbon-source. In PNAS: www.pnas.org/doi/abs/10.1...

New Study in ES&T! Permafrost peatlands accumulate mercury from distant sources, but thaw causes collapse into wetter bogs and fens. Lauren Thompson shows that these bogs, and especially fens, become hotspots for mercury methylation, and potential downstream transport.

A year of seasonal 🇨🇦 field sampling ending! We’re studying soils that feed lakes and sediments that accumulate on lake bottoms. These rich carbon stores keep greenhouse gases out of the atmosphere, so understanding them better will improve our ability to predict and mitigate climate change. ☀️

Celeste has spent the last few weeks in the forests of NW Ontario as part of her PhD research with help from Antonin visiting as an intern from @insa-lyon.fr. Working with @waterik.bsky.social and others, she has been studying headwaters - where streams begin! 🌊

Thank you to the Algonquins of Barriere Lake (Mitchikanibikok Inik) for hosting us to learn about some of the challenges they face in protecting water quality and fish habitat. We will be working together over the next 3 years to deliver community-led solutions.

Back in the field to complete our Spring sampling campaign 🌸 This year we are studying the contributions of soils to the lakes they surround. How does carbon flow from land into water? What happens to soil carbon when it meets water? Important questions for climate change mitigation.

Excited 😀 that our contribution to the amazing #DarkDivNet led by @macroecologyut.bsky.social is now published @nature.com. The main discovery is that many species that we should find in nature are effectively missing because of human impacts. Read the paper for free: rdcu.be/eg3eA 🧵 1/3
