* Warming-induced increase in aerosol number concentration likely to
moderate climate change : Nature Geoscience [1 Update]
I think one has to be very careful with increasing aerosols in the lower
levels of the atmosphere. Increasing aerosols in the lower atmosphere has
been well known to increase the albedo of the planet.
However if you don't have the correct paramaterised vertical velocity
distributions for the lowest parts of the atmosphere, then you will get
the dissipation and removal of increased aerosol concentrations wrong.
In certain parts (POCS for example in startocumulus clouds), aerosols are
completely removed. Thus unless you get the smaller scale weather
processes right (precip cumulus clouds will do this hoovering very well)
This a a big cause of concern that I feel was not well addressed in this
paper (I could well be wrong!)
Cheers
Alan

Greg,
What I'm struggling to weave together is a method which can address

If you look at current emissions (too high and still rising slightly), plus
the lock-in effect of current and near-term planned infrastructure (e.g.
the WRI report on massive planned worldwide ...more

I think it's worth noting that the magnitude of the feedback is small.
Their order-of-magnitude estimate is -0.01 W m-2 K-1. Locally it gets
larger, and the idea is very interesting, but I'm ...more
