It doesn't get any better than this.
Yes Gamma rays cause cloud cover change. Indeed the sun itself, along
with space, offers a picture of great chaotic inputs into climate.
Your link, David.
You see, the problem not addressed here is how does the biosphere
deal with this added chaotic inputs--which are electrical (gamma rays
increase proton concentrations on the ground and that electrical
potential I lectured Vort on earlier today) (the sun's lumenousity
AND EMF behavior varies).
Indeed, CO2 IS critical in the EMF dynamic--how it is modulated.
Metaphorically, it is like the difference between turning the heat
down and taking an aspirin--when the issue is your body temperature
with a fever.
It's all electrical and biological, baby.
