Abstract

We are still getting used to a “new normal” of devastating summer heatwaves. But the effects of a warming climate are being felt throughout the year, and recent autumn months have been further off the charts than ever. In fact, climate change and an El Niño have both contributed to the world in 2023 having its hottest autumn since records began in 1850. September was 0.93°C above the 1991-2020 average, and a whole 1.75°C above the 1850-1900 pre-industrial reference period. October was also the hottest on record, at 0.85°C above the recent average. This hot autumn has already meant stronger storms and more intense rainfall and droughts. And this in turn affects farming, energy, tourism and other sectors that depend on reliable seasons.
