Climate Tipping Points Could Be Triggered by “Committed Warming”
Unless we rapidly reach net zero emissions, the climate will inch closer to a point of no return—even after greenhouse gas emissions are reduced.

Adding Oxygen to a Lake to Explore Methane Emissions
A rare whole-lake experiment suggests that in some cases, low-oxygen conditions may have a smaller impact on methane release to the atmosphere than previously thought.

Rivers Are Warming Up and Losing Oxygen
Researchers used deep learning to fill in the gaps of “patchy” water quality data, revealing decades-long trends toward warmer and less oxygenated rivers that could have worrisome consequences.

Using Bayesian Estimation to Improve Methane Inventories
A Bayesian, optimal estimation evaluation of state-of-the-art methane inventory with satellite-based emissions from 2009 to 2018 finds substantial differences for livestock, rice, and coal emissions.

Reducing Aerosol Climate-Forcing Uncertainty: A Three-Way Street
To reduce persistent aerosol-climate-forcing uncertainty, new in situ aerosol and cloud measurement programs are needed, plus much better integration of satellite and suborbital measurements with models.
