But even more impressive is the change since the last big peak in global temperature in January 2007 at 0.594°C, giving a 16 month ∆T of -0.774°C which is equal in magnitude to the generally agreed upon “global warming signal” of the last 100 years.
As a reader here brilliantly snarked, "If only there were some sort of natural factor that could explain global temperature variations... It would have to be massive, though. Approximately on the magnitude of our own Sun."
