Big news last week was that new findings published in Nature magazine showed that human emissions of aerosols (primarily from fossil fuel use) have been largely responsible for the multi-decadal patterns of sea surface temperature variability in the Atlantic ocean that have been observed over the past 150 years or so. This variability—commonly referred to as the Atlantic Multidecadal Oscillation, or AMO—has been linked to several socially significant climate phenomena including the ebb and flow of active Atlantic hurricane periods and drought in the African Sahel.
This paper marks, in my opinion, the death of credibility for Nature on global warming. The first symptoms showed up in 1996 when they published a paper by Ben Santer and 13 coauthors that was so obviously cherry-picked that it took me and my colleagues about three hours to completely destroy it. Things have gone steadily downhill, from a crazy screamer by Jonathan Patz on mortality from warming that didn’t even bother to examine whether fossil fuels were associated with extended lifespan (they are), to the recent Shakun debacle. But the latest whopper, by Ben Booth and his colleagues at the UK Met Office indeed signals the death of Nature in this field.
