dr. lovelock.gnize you as a medical doctor and as such when i heard from you tonight was looking at the patient as a living organism and not a set of molecules and chemicals. and minerals, was basically taking that approach. as such we have had the psychology now for 65 years as a field and many of those early scientists came out of the background of natural history which you alluded to as a natural component in monitoring what is happening in climate change. i am curious why those ideas haven't been at the ipcc table. that is my first question and second you suggested the solar thermal in desert was a potential solution to the climate change problem and that certainly seems to make sense in an area you are having increasing desert location if you are observing the excess light to produce energy in the sense modulate conditions the question on that one is why do you think that technology has not seen more development since its 30 years of proven systems out there? >> can i answer the second questio
