Trenberth and Fasullo Try to Keep the Fantasy Alive

Trenberth and Fasullo published a paper “An Apparent Hiatus in Global Warming?” last week in the new online journal Earth’s Future. Judith Curry briefly introduced the paper in her December 7, 2013 post Week in review (Thanks, Judith.) From the last sentence of the abstract, Trenberth and Fasullo (2013) argues that: Global warming has not…

New study shows Pacific Decadal Oscillation and sea surface temperature drive US tornado strength

From the University of Missouri-Columbia, one more example of how natural variation has trumped the supposed forcing of CO2 to make ‘bad weather’. Pacific ocean temperature influences tornado activity in US, MU study finds COLUMBIA, Mo. – Meteorologists often use information about warm and cold fronts to determine whether a tornado will occur in a…

Chylek et al 2013 shows a linkage between US Southwest climate and AMO/PDO cycles

This paper suggests that the CMIP5 models’ (which IPCC relies upon) predicted US SW temperature sensitivity to the GHG has been significantly overestimated by about a factor of two. Imprint of the Atlantic multi-decadal oscillation and Pacific decadal oscillation on southwestern US climate: past, present, and future Petr Chylek •    Manvendra K. Dubey • Glen…

Climate change is dominated by the water cycle, not carbon dioxide

Guest essay by Steve Goreham Originally published in The Washington Times Climate scientists are obsessed with carbon dioxide. The newly released Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) claims that “radiative forcing” from human-emitted CO2 is the leading driver of climate change. Carbon dioxide is blamed for everything from causing more…

Unwarranted Temperature Adjustments and Al Gore’s Unwarranted Call for Intellectual Tyranny

Guest essay by Jim Steele, Director emeritus Sierra Nevada Field Campus, San Francisco State University For researchers like myself examining the effect of local microclimates on the ecology of local wildlife, the change in the global average is an absolutely useless measure. Although it is wise to think globally, wildlife only responds to local climate…

On Muller et al (2013) “Decadal variations in the global atmospheric land temperatures”

I received an email yesterday morning advising me that Muller et al (2013) had been published. (Thanks, Marc.) The title of the paper is “Decadal variations in the global atmospheric land temperatures”. The abstract is here and a preprint version of the paper is available from the Berkeley Earth Surface Temperature website here. The primary…
