The Signal and the Noise: The Art and Science of Prediction: Nate Silver on the climate numbers

by JasonK January 19, 2013

Nate Silver is a math pundit who founded the fivethirtyeight blog now over at the NY Times. That blog was all about the presidential election and over there he used a series of polls to predict (very successfully) the results of both the 2008 and 2012 US elections. An integral part of Nate’s approach is to use [...]

A new world record(?)

by Gareth December 23, 2012

Last week the UK Meteorological Office issued its annual forecast for the global average temperature for the year ahead. They’re expecting a warm year, but very few people seemed to notice just how hot. Here’s what the press release had to say: 2013 is expected to be between 0.43 °C and 0.71 °C warmer than [...]

NIWA v cranks: costs are in, losers start whinging

by Gareth October 16, 2012

Having successfully defended the High Court challenge to its New Zealand temperature reconstructions brought by NZ’s climate cranks and being awarded costs by the judge, the National Institute of Water and Atmospheric research (NIWA) is said to be seeking costs of $118,000 from the plaintiffs. Richard Treadgold, the instigator of the whole sorry affair, has [...]

Exclusive: Flat Earth Society appeal to NZ climate sceptics – join us!

by Gareth July 16, 2012

As New Zealand’s climate “science” coalition, in the guise of the NZ Climate Science Education Trust gets its day in court in its long running attempt to get the NZ temperature record declared invalid, a mole inside the Flat Earth Society has sent me the text of a letter being handed out to the CSET [...]

Still warmin’ after all these years (Prat watch #5.6)

by Gareth April 30, 2012

Courtesy of Texas state climatologist John Nielsen-Gammon, a very nice graphical demonstration of why “warming” hasn’t stopped in the last decade (or two). Nielsen-Gammon took the GISS global temperature series, classified years as El Niño dominated, neutral, or La Niña, excluded the influence of the Pinatubo-cooled years in the early 90s, and then calculated the [...]

Cuckoo cocoon (Prat Watch #5.5)

by Gareth April 16, 2012

Something stirred inside the carefully cultivated cocoon of ignorance at Richard Treadgold’s Climate “Conversation” blog, but I don’t think it was the butterfly of understanding preparing to inflate its wings. Something much more subterranean, I suspect. Needled by my post about said cocoon (namely, Treadgold’s insistence that “global warming has not happened for about 15 [...]

2011: a hot cold year

by Gareth January 22, 2012

The NASA numbers are in, and 2011 was the ninth warmest year since 1880 — 0.51ºC above the 1951-80 global mean. Nine of the ten warmest years in the long term record have occurred in this century. According to the analysis released by James Hansen and his team at GISS, a combination of low solar [...]

McLean’s folly 2: the reckoning

by Gareth January 12, 2012

Ten months ago, Aussie “sceptic” John McLean predicted that 2011 would be “the coolest year since 1956″. I pointed out at the time that this was nonsense, and so it has proven to be. I’ve taken the GISS global temperature figure for Jan – Nov 2011 (+0.51ºC compared to the 1951-80 average) and added it [...]
