As wildfires ravaged the Greek island of Rhodes, and scorching heat gripped the U.S. Southwest, scientists now anticipate that July 2023 will go down as the hottest month ever recorded. A recent analysis by Leipzig University in Germany reveals that this month’s global mean temperature is projected to be approximately 1.5 degrees Celsius (2.7 Fahrenheit) above the pre-industrial mean, shattering previous heat records.
Comparing data with July 2019, the previous record-holder for the warmest July in the 174-year observational record, European Union data indicates that July 2023 will surpass it by at least 0.2C (0.4F). Leipzig climate scientist Karsten Haustein confidently stated that the margin of difference is significant enough to conclude that this July will indeed be the warmest on record.
Climate scientist Michael Mann from the University of Pennsylvania pointed out that by mid-July, it was evident that this month would set a record for warmth, highlighting the ongoing consequences of burning fossil fuels on our planet’s temperature.
Normally, the global mean temperature for July hovers around 16C (61F), including the Southern Hemisphere’s winter. However, this year, it has surged to nearly 17C (63F). The U.N. World Meteorological Organization (WMO) also expects that July 2023 will break records, but final confirmation will await the availability of all data.
The impact of the extreme heat has been felt across vast regions. The U.S. state of California’s Death Valley experienced the hottest night ever recorded globally this month. Northwest China saw temperatures reach as high as 52.2C (126F), setting a national record.
Sweltering heatwaves affected several European countries, with temperatures soaring into the mid-40s on Italy’s Sicily, parts of which were engulfed in flames due to wildfires. Marine heatwaves emerged along coastlines from Florida to Australia, posing risks to coral reefs.
Even Antarctica, known for its extreme cold, is experiencing the effects of the heat. Sea ice in the Southern Hemisphere’s winter is currently at a record low, contrary to the time when ice should be reaching its maximum extent.
Record-breaking rainfall and floods have inundated South Korea, Japan, India, and Pakistan. The planet is also witnessing the early stages of an El Nino event, which typically brings warmer temperatures worldwide, amplifying the impacts of human-induced climate change.
Scientists predict that either 2023 or 2024 will become the hottest year in recorded history, surpassing the previous record set in 2016. The effects of El Nino are expected to peak later this year and continue into 2024, further contributing to rising temperatures.
