When Human Caused Climate Change Appeared in the Temperature Record

Caption

Median time of anthropogenic emergence and zonally averaged signal and noise for climate means and extremes are shown. Maps of median TAE averaged across 23 model simulations for (a) and (b) mean surface air temperature, (c) and (d) highest daily maximum temperature, (e) and (f) lowest daily minimum temperature, (g) and (h) total precipitation, and (i), (j) maximum 1-d precipitation for (a), (c), (e), (g) and (i) June-August and (b), (d), (f), (h) and (j) December-February. Zonally averaged values of signal (red) and noise (black) are shown where signal is the mean difference in the variable between 1989-2039 and 1860-1910, and noise is the standard deviation of the variable for 1860-1910.
