Could SAI also cool by reducing cirrus cloud cover in northern hemisphere?

[Ron Baiman]

Dear Colleagues,

See this 5/7/2022 Reviewer 2 podcast with Moa Spoore of Lund Univ:https://podcasts.apple.com/us/podcast/cirrus-clouds-and-aerosol-rain-out-sporre/id1529459393?i=1000559937216

Moa Sporre schools @geoengineering1 on what happens to aerosols that fall out of the stratosphere and into cirrus clouds. Prior project mentioned: CARIBIC project (nowadays part of IAGOS): https://www.caribic-atmospheric.com Paper discussed: Sporre, M. K., Friberg, J., Svenhag, C., Sourdeval, O., & Storelvmo, T. (2022). Springtime stratospheric volcanic aerosol impact on midlatitude cirrus clouds. Geophysical Research Letters, 49, e2021GL096171. https://doi. org/10.1029/2021GL096171

In reference to this podcast I'm also copying the link to the 3/10/2022 Healthy Planet Action Coalition (HPAC) presentation by David Mitchell on cirrus cloud thinning:
