Uncharted Heat: July 22 Marks Hottest Day in Global History

On July 21, 2024, the Copernicus Climate Change Service (C3S) recorded the highest global average surface air temperature ever, reaching 17.09 degrees Celsius. This surpasses the previous record of 17.08 degrees Celsius set on July 6, 2023. The 21st July record was further surpassed the next day on 22nd July, with record temperatures at 17.15°C.  Carlo Buontempo, director of C3S, emphasized that this new record highlights the unprecedented global heat observed over the past 13 months, signaling that climate change is propelling us into “uncharted territory.” 

The sudden rise in the daily global average temperature is linked to significantly above-average temperatures across vast regions of Antarctica. Increased atmospheric greenhouse gas emissions are accelerating melting of ice sheets in the polar regions, causing this unprecedented increase in global temperatures. Antarctica is experiencing warming at twice the global average rate, whereas the Arctic is warming at four times the global average, exceeding the rates predicted by climate models. (Casudo,2023; Rantanen, 2022). Copernicus warns that these record-breaking temperatures might continue, with further fluctuations anticipated in the coming weeks.  

Increase in frequency of record high temperatures in the polar regions undermines the stability of ice shelves, with multiple local and global impacts including increase in frequency of devastating extreme weather events. In 2024 alone, severe heatwaves have afflicted North America, Mexico, India, and Thailand, while devastating floods have impacted East Africa, China, and Brazil. Wildfires have ravaged parts of southern and eastern Europe, Canada, and the United States, fueled by prolonged scorching temperatures and dry conditions. 

The primary driver of global warming is the burning of fossil fuels, which leads to rising emissions of heat-trapping greenhouse gases. International efforts to transition to clean energy are failing, including emission reduction targets set by countries that signed the Paris Climate Accord in 2016. As a result, 2023 became the hottest year on record, with 2024 potentially following suit given the persistent warm temperatures experienced thus far. Presently, the goal to keep global temperatures below 2C pre-industrial levels is farfetched and ambitious with science deeming it to be unfeasible. 

This alarming trend of record high temperatures underscores the urgent need for global action to mitigate climate change, reduce greenhouse gas emissions, and adopt sustainable practices to safeguard our planet’s future.
