The paper joins more than 1000 other non-hockey-sticks published in the literature demonstrating global temperatures were naturally as warm or warmer than the present over the past 10,000 years.
|Reconstructed temperature in left graph starting from ~25,000 years ago during the last ice age. Horizontal axis on left graph is thousands of years before the present. Red line is land temperatures, blue line is sea surface temperatures, and black line is Atlantic inflow [which is stable and in middle of the range over the Holocene]. Note the final land temperature datapoint in ~2010 was one of the lowest since 1950.|
