WMO 2013 climate summary: laws of physics not negotiable, extremes to be expected on a warming planet

by Gareth March 25, 2014

The World Meteorological Organisation’s (WMO) state of the climate report for 2013 was released on Sunday (pdf), and provides a very useful overview of last year’s weather and climate events. It confirms that 2013 was the 6th warmest year in the long term record (tied with 2007), that 13 of the 14 warmest years in […]

Still warming after all these years (again)

by Gareth January 10, 2013

Spread this excellent new video from the talented team at Skeptical Science far and wide. It explains why the latest denialist trope — no warming for 16 years — is rubbish. Take out the impact of the three biggest factors driving natural variations in the global average temperature — volcanoes, the El Niño Southern Oscillation […]

Here’s a superb video from the Department of Education at the American Museum of Natural History, showing how NZ and US scientists are examining the precise timing of glacier advances and retreats in the Mackenzie country around Lake Pukaki using surface exposure dating. Like all good geologists they use big hammers and small explosives to […]

Shang a de Lange

by Gareth May 3, 2012

Much exercised by the question of ocean warming, New Zealand’s most litigious temperature savant posts excerpts from an article on the subject, and thanks Waikato University’s Willem de Lange for introducing him to this “really clear treatment of ocean warming and ocean-atmosphere interaction”. Two things are interesting about Treadgold’s post, and neither has anything to […]

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 […]
