wave components reflected backward and
slowed down,
while other parts reflected forward and sped up.
However, recent studies have shown that sleep - deprived animals can exhibit
slow waves in parts of their brain

What I am saying is that it makes no sense at all to hand -
wave at the effects of uncontrolled volcanic eruptions as «absolute proof» that geoengineering schemes «can work»,
while promoting a gradual 50 - year phaseout of GHG emissions (which is too
slow to have any hope of preventing catastrophic outcomes) as «logical» (whatever that means) and ignoring the multiple studies that show we can easily phase out emissions in a fraction of that time with the proven technologies that are already at hand.
