Hi all, The reports from Poznan do suggest a note of desperation. I am glad Albert now agrees that geoengineering has to be part of the solution. I hope others will be persuaded.
The rapidity of Arctic sea ice summer retreat is an immediate problem. That web page, which Albert refers to, contains this link: http://news.bbc.co.uk/1/hi/sci/tech/7692963.stm If the last winter (2008) ice had thinned 10% below the 2002-2008 average, and the minimum extent this September (2008) was just a little over the record in 2007, then the volume of ice was almost certainly a record minimum this September. This is why Albert and I believe that the sea ice could practically disappear at end summer 2011, especially if things go against us, e.g. with an El Nino and increased solar activity. (We've not had an El Nino since 1998, and solar activity has been low - hence little overall warming.) BTW, the volume of ice is a better indicator than extent, as it is an integration of temperature over time. This is similar to the "glacier ice mass loss" indicator (also "cumulative mean thickness"), which has shown a consistent decline since mid 80s, but note flattening off for the two years of Pinatubo volcanic aerosol cooling (1991-2), e.g. at: http://en.wikipedia.org/wiki/Image:Glacier_Mass_Balance.png Cheers, John ----- Original Message ----- From: Albert Kallio To: Geoengineering FIPC Sent: Wednesday, December 10, 2008 8:23 PM Subject: [geo] Geoengineering Becoming Increasingly the Last Solution to Fix Climate > BBC Report on Inadequacy of CO2 Cuts Hi All, This BBC report appeared today outlining the rather dire prospects to manage climate change. I think that geoengineering is definitely now required as a part of solution to this worsening mess. Yours sincerely, Veli Albert Kallio, FRGS Poor countries 'need carbon cuts' Developing countries need to make big cuts in greenhouse gas emissions if "dangerous" climate change is to be avoided, a report warns. < http://news.bbc.co.uk/go/em/fr/-/2/hi/europe/7773799.stm > ------------------------------------------------------------------------------ Read amazing stories to your kids on Messenger.
