Fig. 3: Frequency change of 1-in-100-year monthly heat and meteorological drought events attributable to global top emitters.
From: High-income groups disproportionately contribute to climate extremes worldwide
a,b, Monthly distributions of heat extremes (a) and drought extremes in the Amazon (b) across grid cells attributable to the global top 10%. Distributions were derived by first computing the median attribution results at each grid cell (estimated from 15,000 ensemble members each) and then computing statistics across all 2,652 grid cells. Colour shading is qualitative. c,d, Spatial distribution of the median number of heat (c) and drought (d) extremes during peak temperature months attributable to the global top 10%. Median estimates are derived from 15,000 ensemble members. Hatched regions indicate insignificant results and/or insufficient model agreement. e,f, Median number of additional heat (e) and drought (f) extremes by region (highlighted on the maps in c and d). CIFs indicating the group’s contribution to extremes relative to the average contribution are given above the bars. Vertical lines correspond to 5th–95th confidence intervals. We omit showing global drought estimates because of insufficient agreement among grid-cells. Distributions were derived by first computing median attribution results at each grid cell (estimated from 15,000 ensemble members each) and then computing statistics across all grid cells within each region.
