Dear Ed,
Powerful stuff - keep up the pressure!
Have completed a major revision of my work on Radiative
Forcing, Climate Sensivity and Boundary Conditions of Runaway Climate
Change. The latest edition is attached. It includes most
recent evaluation of strong water vapour feedback and a new section on
the Boundary Conditions of Runaway Climate Change. Conclusions
are presented in the Executive Summary. You will see that I am now
certain we have passed the threshold of runaway behaviour in the
climate system with only a narrow window left to restabilise it.
You will also see the conclusion that attempting to maintain a
concentration level of 440 ppm of CO2 equivalent does not lead to an
eventual equilibrium of 2 degrees above pre-industrial temperature, or
at any other level! The threshold of runaway behaviour is already
activated at this concentration.
The current economic crisis should be seen as the canary in
the coalmine of climate dynamics. The tragedy is that all
investment is geared to find ways to resuscitate dead canaries rather
than paying attention to the iminent danger at the coalface!
Keep up the good work,
David
