World on Brink of Breaching Dangerous 1.5°C Warming Threshold

Experts warn world may breach 1.5°C warming threshold soon, a dangerous climate tipping point.

Global temperatures January-September 2022 were 1.4°C above pre-industrial levels.

September 2022 was 0.93°C warmer than 1991-2020 average and 1.75°C above 1850-1900.

1.5°C threshold already breached temporarily this year due to El Niño warming effects.

Crossing 1.5°C mark risks triggering Arctic ice melt, circulation changes, and catastrophic climate impacts.
