Last month’s record-breaking July temperatures

Last month was the hottest July ever recorded, with global mean surface air temperature for the first 23 days standing at 16.95C. Researchers say climate change, mainly caused by the extraction and combustion of fossil fuels, was to blame for a hotter-than-usual July.

Study reveals impact on global population

More than 6.5 billion people – approximately 81% of the global population – experienced a hotter July, a new study has found.

The new report, released Wednesday by Climate Central, calculated climate change attribution assessments for 4,700 cities across 200 countries. Scientists concluded that more than four out of every five people on the planet faced climate change-attributed heat last month, which was also the hottest July ever recorded

Impact on local temperatures

In particular, over 6.5 billion people experienced “at least one day” of heat that was amplified at least threefold by climate change. Moreover, during each day of the month, 2 billion people worldwide experienced at least that same level of climate change influence on their local temperatures. 

Daily average temperature Climate Shift Index (CSI) averaged over July 1-31, 2023. The CSI has 11 levels indicating how climate change has altered the frequency of daily high, low, and average temperatures at a given location. For example, CSI Level 3 indicates that human-caused climate change made temperatures at least three times more likely. Image: Climate Central.
