The theory linking man-made CO2 with dangerous global warming is dead. It has been falsified. It has run smack bang into a â€œnull hypothesis.â€ It has met its Waterloo. It has bought the farm. It has gone for a Burton. It has cashed in its chips, fallen off its perch, gone south, gone west, shuffled off this mortal coil, run down the curtain and joined the Choir Invisible.Â Man-made Global Warming has ceased to exist.
Eschenbach wrote his post in response to a bizarre speech prepared by Dr Kevin Trenberth of the National Center for Atmospheric Research (NCAR), which he intended to deliver to the American Meteorological Society. Trenberth is the arch-warmist perhaps best known for writing the Climategate email which went:
The fact is that we canâ€™t account for the lack of warming at the moment and it is a travesty that we canâ€™t.
When Trenberthâ€™s speech was pre-published on the internet it caused something of a stir, both for the way large chunks of it had been taken almost verbatim from another scientist and for its use six times of the word â€œdenierâ€. (Thanks to some kindly advice proferred by Steve McIntyre, Trenberth has now significantly altered his speech. â€œDeniersâ€ has been altered to â€œsceptics.â€ Probably quite sensibly since many in the AMS, being meteorologists rather than â€œclimate scientistsâ€ tend very much to fall into the sceptic camp).
What Eschenbach focuses on, though, is Trenberthâ€™s absurd demand that the â€œnull hypothesisâ€ on AGW theory be reversed. That is, instead of having to prove AGW exists, what people should now be required to prove that it doesnâ€™t exist. (!)
