The Facts

A new study published by World Weather Attribution and Climate Central on Thursday found that the world will add approximately 57 "superhot" days annually by 2100 if countries fulfill their Paris Agreement emission-reduction pledges, limiting warming to 2.6 degrees Celsius above preindustrial levels.

Since 2015, the world has already experienced an average of 11 additional superhot days per year, defined as days with temperatures warmer than 90% of comparable dates between 1991 and 2020 at each location.

Without the Paris Agreement's emission-reduction efforts, Earth would have faced an additional 114 superhot days per year by century's end — twice the increase compared to current projections under the agreement's framework.

The 10 countries facing the largest increases in dangerous heat days are predominantly small, ocean-dependent nations that collectively produce only 1% of global heat-trapping gases but will experience nearly 13% of additional superhot days.

The report suggests that major carbon-polluting countries, including the U.S., China and India, are predicted to experience only 23 to 30 extra superhot days despite being responsible for 42% of atmospheric carbon dioxide but receiving less than 1% of additional heat.

Heat adaptation efforts have expanded with 104 countries now issuing extreme heat warnings and 47 having national heat action plans. However, financing remains limited, with heat adaptation projects receiving less than 2% of global climate finance.

Climate-skeptic narrative

Climate change and global warming predictions have a horrific track record. Record-breaking cold is crushing the globe as early winter obliterates autumn across continents. Alberta just shattered 121-year temperature records, China plunged to minus 23 degrees in October, and Russia hit historic gas demand from brutal freezes. Antarctica is now colder than at any time in the past 5,000 years, while predictions of global warming crumble amid real-world data showing a cooling planet.

Climate-concerned narrative

The Paris Agreement is already delivering massive climate benefits by cutting future extreme heat in half. Without this treaty, the world would face 114 scorching days annually by 2100, but current commitments slash that to just 57. Countries like Kenya will avoid 82 fewer brutal heat days each year, while the U.S., India, China and Britain dodge 30 fewer days of dangerous temperatures. A 2.6-degree temperature rise by the end of the century could lead to catastrophic consequences.
