Summary

Description
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.

  • Source states:
  • Hot temperature extremes over land - 10-year event - Frequency and increase in intensity of extreme temperature event that occurred once in 10 years on average in a climate without human influence
  • Hot temperature extremes over land - 50-year event - Frequency and increase in intensity of extreme temperature event that occurred once in 50 years on average in a climate without human influence
  • Heavy precipitation over land - 10-year event - Frequency and increase in intensity of heavy 1-day precipitation event that occurred once in 10 years on average in a climate without human influence
  • Agricultural & ecological droughts in drying regions - 10-year event - Frequency and increase in intensity of an agricultural and ecological drought event that occurred once in 10 years on average across drying regions in a climate without human influence
  • Version 2 avoids a possible wrong inference from Version 1's use of rectangles formed by multiplying frequency (horizontal axis) and intensity (vertical axis) to form a large rectangle. See this explanation at en.wp's Talk:Climate change. Version 2 is a horizontal bar chart (frequency) and a vertical bar chart (intensity).

06:31, 13 December 2021Thumbnail for version as of 06:31, 13 December 20211,225 × 693 (5 KB)RCraig09Version 16: change horizontal bars so that they lie "flat" (in a ~simulated horizontal plane)
17:35, 27 November 2021Thumbnail for version as of 17:35, 27 November 20211,225 × 693 (5 KB)RCraig09Version 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
15:26, 24 November 2021Thumbnail for version as of 15:26, 24 November 20211,225 × 693 (5 KB)RCraig09Version 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)
16:51, 23 November 2021Thumbnail for version as of 16:51, 23 November 20211,225 × 693 (5 KB)RCraig09Version 13: adding light gray line to more clearly visually distinguish horizontal from vertical bars for 4 °C. . . . making horizontal grid lines same color
23:28, 22 November 2021Thumbnail for version as of 23:28, 22 November 20211,225 × 693 (4 KB)RCraig09Version 12: 3-dimensional vertical bars: make clear how far horizontal bars extend, and height from which vertical bars extend . . . changing lengths of grid lines

03:13, 20 November 2021Thumbnail for version as of 03:13, 20 November 20211,225 × 693 (4 KB)RCraig09Version 10: re-format so vertical bars are centered above end of horizontal bars, to remove ambiguity about where horizontal bars end
07:11, 19 November 2021Thumbnail for version as of 07:11, 19 November 20211,225 × 693 (4 KB)RCraig09Version 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.
