A couple of days ago one of the leading figures in the New Zealand climate crank pantheon, the Climate “Science” Coalition’s very own Bryan Leyland, popped in to Hot Topic and left a comment drawing attention to his new favourite game — “predicting” global temperatures by projecting the southern oscillation index forward seven months. He bases this on the “work” of John McLean, last mentioned here a couple of months ago when I looked at his prediction (happily promoted by the NZ C”S”C) that 2011 will be the “coolest year globally since 1956 or even earlier”. Suffice to say, it won’t be.
Leyland first notes the infamous McLean, De Freitas and Carter paper of 2009, then his own “prediction” that this year’s La Niña would bring a cooling in global temperatures, and then says:
What is remarkable about this is that a retired engineer with access to the Internet has been able to make accurate predictions of future climate. Yet, to my knowledge, no computer-based climate model nor any mainstream “climate scientist” predicted this cooling. To me, this is truly remarkable.
What’s really remarkable is that Leyland is actually only showing his ignorance of some pretty basic climate relationships.
