RE: [geo] Weakening of the extratropical storm tracks in idealized solar geoengineering scenarios

No.  Every model that has ever simulated solar dimming shows that the poles 
would cool relative to not dimming the sun.  But, if you just turn the sun down 
then you “undercool” the poles.  The plot is G1 relative to pre-industrial, not 
G1 relative to 4xCO2.

(These are the exact same model simulations that you’ve asked the exact same 
question about before.)

Hi All

Do the brown bits in figure S1 mean polar warming would be caused by solar 
dimming in all six models?

Key Points:
• Northern extratropical storm tracks weaken by comparable amounts under 
idealized
global warming and solar geoengineering scenarios
• Southern extratropical storm track strengthens under idealized global 
warming, but
weakens under idealized solar geoengineering
• Storm track intensity changes quantitatively consistent with changes in mean 
temperature
structure and moisture content
