Dear All
So sorry not to send yr unique Card but I hope you wont mind.
The shock of Robs death and his loss has been almost unbearable
for all of us, and added to that the death of Mike creates an almost
unbearable
situation,On a lesser not y dementia my dementia has made life very wonky.

have been rigorously field-tested. It is not sufficient to say that MCB
will work because ship-tracks enhance cloud brightness.

Hello John, Ken et al.,
I've always liked climate restoration because - though we'll never
achieve it precisely - it's what we're seeking, and is much less
likely to scare the pants off the public than the imperious
geo-engineering.
But when we're trying to be as exact as possible my
appropriate term might well be impact intervention--save geoengineering,
climate restoration, and global temperature stabilisation for the
efforts (e.g., by global sulfate injection, mirrors in space, etc.) to limit
global climate change.
