Hansen, J., M. Sato, and R. Reudy, 2013: Reply to Rhines and Huybers: Changes in the frequency of extreme summer heat. Proc. Natl. Acad. Sci., 110, E547-E548, doi:10.1073/pnas.1220916110.

Rhines and Huybers are correct that the decreasing number of measurement stations in recent years contributed slightly to our calculated increase of extreme summer mean temperature anomalies. However, the increased frequency of extreme heat anomalies is accounted for mainly by (i) higher mean temperature of recent decades relative to the base period 1951-1980, and (ii) the continuing upward temperature trend during recent decades.
