La Niña Years Warmer Than Ever: Climate Crisis Accelerates
15 Jan
Summary
- Recent La Niña years show unprecedented warming, exceeding pre-industrial averages.
- Reduced atmospheric sulphate pollution, though healthy, is accelerating global warming.
- The 1.5°C warming threshold may be crossed by the end of this decade.
The world has experienced significantly warmer La Niña years recently, with 2022 recording 1.15°C above pre-industrial averages. This warming trend has continued, with the past three years averaging between 1.48°C and 1.5°C warmer, a notable departure from earlier decades. Scientists attribute this surge to persistent increases in greenhouse gas emissions and a surprising side effect of pollution reduction.
