I have observed an enormous amount of valuable discussion on this googlegroup. People have violently diverse views on how to move forward. The discussions have influenced my opinions on some tough philosophical aspects of geoengineering and the climate crisis, and I'm sure it does the same for

Hi Oliver, I think we should all be extremely alarmed by what Albert has said!! So a plan of action is urgently needed. I've been talking about this with Albert, on and off, for nearly two years now. Somehow we have to stabilise the Greenland ice sheet. But if we do not save the Arctic sea

Greg GWP's by design ignore all climate impacts beyond 100 years. This has real consequences as it makes methane look relatively more important that it should be, and it also overweight's the beneficial impacts of biomass sequestration in some calculations. While some traditional

Thanks, David. I agree. Failure to appreciate long term effects and ocean acidification impacts, together with questionable/opaque discounting schemes has I believe resulted in CO2 mitigation being greatly undervalued by the economists and this is significantly undermining policy and

The other problem with 100-year GWPs is that they tend to hide all that can be done with the short-lived species (black carbon, methane, ozone precursors), so what we really need to do is to use both 20 and 500+ year GWPs. Use of 100-year GWPs covers up both of the important tails. Mike On

Hi Jim, I want to follow up on your email of 15th November. So far, nobody has challenged the logic of my argument. So we all seem to be in agreement! It's not what we'd like to believe, but the conclusion is clear. Why are most academics among us so reticent? Jim Hansen has noticed this
