Proxy temperature record (blue) and ANN projection (orange) based on input from spectral analysis for this Northern Hemisphere multiproxy.  The ANN was trained for the period 50 to 1830; test period was 1830 to 2000.

Most of the Recent Warming Could be Natural

AFTER deconstructing 2,000-year old proxy-temperature series back to their most basic components, and then rebuilding them using the latest big data techniques, John Abbot and I show what global temperatures might have done in the absence of an industrial revolution.  The results from this novel technique, just published in GeoResJ [1], accord with climate sensitivity […]
