“Spencer: Global Urban Heat Island Effect Study – An Update“. More tortured charts and explanations from Dr. Roy Spencer, merely producing a deeper hole. When he said “I don’t know the reason for this, but I suspect that a little thought from Anthony Watts, Joe D’Aleo & others will help figure it out.“, well… I realized that even by Anthony’s standards I’d wasted five minutes of my life.
Yes, Dr. Spencer’s charts have lines on them. What is lacking is an objective basis for the station pairings he has settled on. Or a cogent theory explaining them.
Dr. Spencer, you have jumped the shark.
