Yes, and I remember the discussion on r.a.s about contrails and their spread-out to form cirrus just after the post-9/11 three day warm period was reported. IIRC the discussion then was about the effect of contrails in the soaring areas beneath flight paths out of large US West Coast airports. -- In the USA there was a rather well done program on NOVA or Frontline (PBS) that investigated the impact of the contrails and concluded that contrails actually contribute to global cooling - not warming! So, how did they explain the 1 degree C rise in ground temperature during the three days when all civil aviation was grounded? -- martin@ * | Martin Gregorie gregorie. | Essex, UK org * * * | you know, according to noetic scientists, the collective consciousness of the world was measurable on that day.................or so I read.
