Just 26 of 193 countries that agreed in 2021 to step up their climate actions have followed through with more ambitious plans. Without drastic reductions in emissions, the planet is on track to warm by an average of 2.1 to 2.9 degrees Celsius, compared with preindustrial levels, by 2100. That’s far higher than the goal set by the 2015 Paris agreement, crossing the threshold beyond which the likelihood of catastrophic climate impacts significantly increases. At least 559 million children worldwide are already exposed to frequent heatwaves—a number that could hit 2.02 billion by 2050. There’s a rising threat of extreme high temperatures, or at least 83.54 days that top 35°C (95°F), as well as events that high in duration–lasting 4.7 days or longer, and severity (temperatures 3.6F or more above the local 15-day average).
