Clouds and aerosolsEarth system models disagree widely on how much sea salt spray is needed to brighten clouds
In this preprint, ten model setups need very different amounts of injected sea salt to reach -2 Wm-2, and the gap comes mostly from particle size, droplet activation and cloud adjustments.

Clouds and aerosolsVolatile exhaust particles can greatly raise contrail ice crystal numbers in low-soot engines
In models, volatile particles formed in the exhaust plume can activate and make many more contrail ice crystals when soot emissions are low, especially with sulfur-rich particles at cold temperatures.
