Earth to Face 57 More Hot Days by 2100: Report

Istanbul: A new study has warned that even if countries fully meet their Paris Agreement pledges, the planet is still on track to warm by 2.6°C (4.7°F) by the year 2100 — a rise that could bring 57 additional extremely hot days every year.

The report, titled “Ten Years of the Paris Agreement: The Present and Future of Extreme Heat,” was jointly released by Climate Central and World Weather Attribution. It examines global extreme heat trends since the 2015 Paris Agreement and projects how current emission commitments will affect future heat extremes.

According to the analysis, if all emission reduction pledges are implemented as promised, global temperatures would be limited to around 2.6°C above pre-industrial levels by the end of the century. However, even under this scenario, the world would face 57 more extremely hot days annually, compared to the current global average of 11 additional hot days under 1.3°C (2.3°F) of warming.

Before the Paris climate goals were adopted — which aim to limit warming to 1.5°C and keep it well below 2°C — projections had estimated a 4°C (7.2°F) rise by 2100. That level of warming would have resulted in as many as 114 extra scorching days each year.

The report highlights that reducing projected warming from 4°C to 2.6°C could spare nearly 30 countries an average of at least 100 excessively hot days per year.

Nations expected to experience the largest increases in extreme heat days at a 2.6°C warming level include the Solomon Islands, Panama, Saint Lucia, Guyana, and Indonesia, the study noted.

“The highest possible ambition, as set out in the Paris Agreement — to achieve deep, rapid, and sustained emissions reductions — is urgently needed,” the study stressed, warning that the “costs of inaction on extreme heat are rising faster than adaptation.”
