The UK's Met Office is not alone in their predictions, as at least one
metastudy I've seen suggests similar dates. However, we should bear in mind
that the track record on AGW is usually that things are worse than expected.
I think that 2060 is pretty soon. I'll still be alive. Furthermore, we
Hi folks:
Let's face it. We are entering the age of climate management. We are
doing it inadvertantly now through emissions, The negative
consequences are forcing us to look at purposeful management of
climate to assure the well-being of humans and the environment. As I

Thank you, David, for your thoughtful reply and the excellent points
you make, which culminate in an acknowledgement of the argument for
albedo geoengineering to save the Arctic sea ice, as I have been
proposing. Your support is most welcome.
Re your point 1, the proposal does not assume a p
Dear Ron (et al)
Sorry this will be a too-short reply as I am currently in the middle

opinion - there is a significant values gulf between us and I strongly

Whew. I'll be ready for you're twisted wit next time!

I don't doubt you have the measure of increasing denialism correctly

Peter, all:
I didn't scan all the way down to the bottom of Peter's email and
missed the interpretation of "Glyn's conspiracy theory" Yikes! It's

Not to worry, I'll be more clear.

Further to Mike,
I would like to draw also attention to terrestrial snow cover. Snow has
increased due to less ice covered Arctic Ocean during the summers and autumn.
This insulates air more from the ground. On the other hand, the amount of
ground heat has increased as the soil beneath snow
Hi fellow Geoengineers:
Early in December, I will have the opportunity to address an R&D
finance panel at the U.S. House of Representatives in D.C. The topic
is: where to focus R&D, and I am presenting on opportunities in
optics. Obviously getting geoengineering out of the doghouse is a key

Hi Greg, what are the worst errors you can point to?

In Ken's 2008 presentation "geoengineering earth's climate"
(http://www.youtube.com/watch?v=vzMVfJKJK_c)
he nicely captures the 4 steps to stabilize the earth's climate as:
1 Diminish end-use energy demand
2 Produce energy without carbon emission
3 Remove radiatively active gasses from atmosph
The reason why the biomass route is so much lower cost than mechanical air
capture depends on the common practice of discounting cash flows.
If you plant trees (very low cost) then they do the CO2 capture job for a
decade or so, depending on the rotation length. When they are mature you can

Ice cover is not the only issue--ice thickness also matters for it takes an
extensive, pretty solid (i.e., very small or no leads) ice cover about a
meter thick or more (with a bit
I think the idea that fossil resources will provide a meaningful constraint on
CO2 emissions does not pass a fact checker's laugh test. We have enough carbon
within the growing reach or our extraction technologies to push CO2
concentrations beyond 5,000 towards 10,000 ppm.
For my own lay-langu

It does snow in the arctic. I'm sure. I was thinking along the lines
of catching moisture when thew temperature is low enough to snow and
adding extra snow with cloud seeding. Whenever it snows there is
obviously moisture in the air. Basically I though we could make it

Actually, it looks to me like it would be far more cost-effective to reduce
methane first. It not only is a more potent greenhouse gas, but it has
significant energy potential that can help pay for emissions reductions.
Why not start there, even world wide, to include developing countries.
