Measurement of a World-Wide Transfer Function for Marine Cloud Brightening

Salter SH

Abstract

Marine cloud brightening with a sub-micron spray of filtered sea water can exploit the Twomey effect to enhance planetary cooling. Several previous climate model results show that it can also affect precipitation in both directions in different places. Modulating the climate model settings for the concentration of cloud condensation nuclei with separate coded sequences in a number of spray regions round the world and correlating each sequence with the resulting weather patterns in observing stations round the world can give an everywhereto- everywhere transfer function of spray from each region to each observing station. The short life of spray allows the best choices of spray regions and seasons. Spray patterns can be modified tactically to suit real-time weather observations.

I'd like to hear from climate scientists and meteorologists on this. Is the system too chaotic and interdependent to be predictable in this fine grained way?

Andrew,

There is a huge difference between meteorologists and "climate scientists” Many Climate people are not worried about extremes and small scale processes (< 100km) , which for me are CRITICAL - with the proviso that paleontologists etc. , e.g. looking at Younger Dryas etc. are worried. The system is both as you suggest. Predictable if you include all the factors , chaotic if you are operating at scales larger. Of course there is always an issue of knowing the initial conditions.

As a meteorologist, I believe the IPCC6 WG1 consensus is a whitewash written by climate scientists who understand little about meteorology ( IPCC6 (2021), Climate Change. The physical basis . https://www.ipcc.ch/report/ar6/1/ )

As a meteorologist CCRA3 is better. ( Slingo, J. (2021) Latest scientific evidence for observed and projected climate change. https://www.ukclimaterisk.org/wp-content/uploads/2021/06/CCRA3-Chapter-1-FINAL.pdf )

I have written a letter to the Guardian saying this and waiting until tomorrow (in case they answer!) before sending it elsewhere. I can send a copy if desired.

Best wishes

Alan
