While countries are making progress at measuring & mitigating methane from fossil fuels, we need to increase our efforts in curbing methane from livestock, rice, & food waste.

Fair. For my day job, I think about protein from a climate and environment perspective. In that case, plant proteins are almost always better for climate.

Mayo Clinic: "Contrary to all the hype that everyone needs more protein, most people in the U.S. meet or exceed their needs."
New US Dietary Guidelines: "Prioritize Protein" and "Consume Dairy" (3 servings of dairy a day?!)
Did the beef and dairy lobby write this? 👀

One result from the recent @projectdrawdown.bsky.social report on climate solutions in SE Asia: Protecting 20% of the most carbon-rich peatlands in Sumatra & Borneo can reduce emissions by 390 million tons CO₂‑eq/yr, roughly equivalent to annual emissions of the UK. drawdown.org/insights/why...

Not trying to nit-pick but you would think if you wanted to convince people the full record of something is released, you would go for sequential file numbers, no? 🤔 drive.google.com/drive/folder...

Excited to share what I've been working on @projectdrawdown.bsky.social: A Drawdown Roadmap for Food, Agriculture, and Land Use in Southeast Asia.
Food & land use generate over half of emissions in the region. We identified hotspots of emissions and the most impactful solution for each province.

Neat image released @esa.int shows a glacier flowing into Ross Ice Shelf. The new Biomass mission's P-band radar is designed to penetrate the forest canopy, but it can also penetrate into ice and is less affected by surface characteristics that can skew measurements. www.esa.int/Applications...

New research from NASA's Goddard Institute for Space Studies finds that the contraction of the world's storm-cloud zones may be a big contributor to the increase in Earth's sunlight absorption.

Looking down at Earth from space, it's clear that how we produce food dominates landscapes.
