Fig. 2: Change in probability of hot extremes from expanding irrigation and other forcings.
From: Warming of hot extremes alleviated by expanding irrigation

Ensemble-mean likelihood of exceeding 99th percentile of daytime temperature (\({\rm{TX}}\)) as simulated by CESM, considering all forcings except irrigation (a), irrigation expansion only (b), and all forcings including irrigation expansion (c). Probability ratios (PRs) are shown for the present-day (1981–2010) relative to the early 20th century reference period (1901–1930), except for b where the reference is a counter-factual present-day world without irrigation.
