How Does Snow Affect the Intensity of Mountain Precipitation?
A new investigation into the sensitivity of extreme precipitation in a changing climate indicates that more winter rainfall and protracted snowmelt may require local adaptations to winter flooding impacts.

Atmospheric Particles Aren’t the Same Cloud Seeds They Once Were
Still, more than half of the seeds required for cloud droplets to form in both the present-day and preindustrial atmospheres are made by trace gases that condense to form minute aerosol particles.
