摘要

描述	English: Orthogonal bar charts of projected increase in frequency and intensity of extreme weather events for several degrees of global warming, based on data from the IPCC's Sixth Assessment Report (AR6), Summary for Policy Makers (publ. 9 August 2021). Suggested caption: : The IPCC Sixth Assessment Report (2021) projects progressively large increases in both the frequency (horizontal bars) and intensity (vertical bars) of extreme weather events, for increasing degrees of global warming. Based on data from Fig. SPM.6 of: Climate Change 2021 / The Physical Science Basis / Working Group I contribution to the WGI Sixth Assessment Report of the Intergovernmental Panel on Climate Change / Summary for Policymakers. IPCC.ch SPM-23. Intergovernmental Panel on Climate Change (9 August 2021). Archived from the original on 4 November 2021.

See this explanation at en.wp's Talk:Climate change. Version 2 is a horizontal bar chart (frequency) and a vertical bar chart (intensity). Uploader generated SVG code manually in a text editor.

目前	2021年12月15日 (三) 22:16	1,225 × 693（4 KB）	RCraig09	Version 17: avoid poor-practice rectangle to left of axis that visually blocked the 0-to-1 portions of horizontal bars ... made left ends of horizontal bars look more 3-D
	2021年12月13日 (一) 06:31	1,225 × 693（5 KB）	RCraig09	Version 16: change horizontal bars so that they lie "flat" (in a ~simulated horizontal plane)
	2021年11月27日 (六) 17:35	1,225 × 693（5 KB）	RCraig09	Version 15: changed three horizontal gridlines at base of three groups of bars to gray and to not be dashed (to emphasize they're 0 values for vertical bars) . . . misc text fill color changes . . . minor nudging of text
	2021年11月24日 (三) 15:26	1,225 × 693（5 KB）	RCraig09	Version 14: offset horizontal bars so they don't completely overlap, so the lowest horizontal grid line intersects the vertical bars in the bars' midlines . . . . lightened color of 4 “C bars so there's more contrast with strokes (edges)
	2021年11月23日 (二) 16:51	1,225 × 693（5 KB）	RCraig09	Version 13: adding light gray line to more clearly visually distinguish horizontal from vertical bars for 4 °C. . . . making horizontal grid lines same color
	2021年11月22日 (一) 23:28	1,225 × 693（4 KB）	RCraig09	Version 12: 3-dimensional vertical bars: make clear how far horizontal bars extend, and height from which vertical bars extend . . . changing lengths of grid lines
	2021年11月20日 (六) 18:51	1,225 × 693（4 KB）	RCraig09	Version 11: make adjacent-box color scale to replace dispersed "1 °C" "1.5 °C" "2 °C" "4 °C" . . . . make all event categories have same color scheme
	2021年11月20日 (六) 03:13	1,225 × 693（4 KB）	RCraig09	Version 10: re-format so vertical bars are centered above end of horizontal bars, to remove ambiguity about where horizontal bars end
	2021年11月19日 (五) 07:11	1,225 × 693（4 KB）	RCraig09	Version 9: adding horizontal grid lines . . . adding white horizontal lines to emphasize that extent of horizontal bars is the entire length and not just to middle of vertical bar.
	2021年11月18日 (四) 19:17	1,225 × 693（3 KB）	RCraig09	Version 8: change SVG code to avoid different scaling in horizontal and vertical directions, to allow strokes (outlines) to be added to L shaped bars. . . . other minor changes
