The New York Times has created several data visualizations depicting how the world will continue to grow hotter over the next century. Charts and maps use historical data starting in 1960 to project the change in the number of days that are 90 degrees or hotter, and users can visualize the warming trend for individual towns and years. For example, Washington, D.C. was expected to experience roughly 24 days a year that were 90 degrees or hotter in 2000. The city now expects 30 such days, and the analysis suggests that the number of days that are 90 degrees or warmer could increase to 53 days by 2080. Hotter temperatures put increased stress on electrical grids and can disproportionately affect low-income communities that lack air conditioning.
