🌆🌱 At #EGU26, Lukas Emmenegger shared a useful “price vs. precision” rule for urban CO₂ monitoring: €100k → 0.1 ppm €10k → 1 ppm €1k → 10 ppm "Low-cost sensor" ≠ "low-cost network." The real investment lies in expertise, calibration, and data processing needed to make the data actionable.

Work led by CIRES' Ben Riddell-Young — which shows recent methane growth is driven by microbial emissions from landfills, agricultural operations, and wetlands — is featured in a new story in the @nytimes.com “There’s more waste and more cows." www.nytimes.com/2026/02/18/c...

Methane Hunters Track Swamp Gas That Is Driving Climate Warming

Methane emissions from wetlands are rising faster than those from industrial sources, prompting concerns about a climate feedback loop.

A temporary weakening of the atmosphere’s chemical capacity to break down methane, combined with elevated emissions from tropical wetlands, drove the sharp increase in atmospheric methane observed in 2020 to 2021, according to a new study in Science. https://scim.ag/4kmtoOQ

Why methane surged in the atmosphere during the early 2020s

The atmospheric methane (CH4) growth rate surged after 2019, peaking at 16.2 parts per billion per year (ppb year−1) in 2020 before declining to 8.6 ppb year−1 in 2023. Using multiple atmospheric inve...
