August Records Highest Global Temperatures Ever Recorded
August has emerged as the hottest August ever recorded worldwide, with global temperatures reaching exceptionally high levels, according to the European Union’s Copernicus Climate Change Service.
The average global surface air temperature during the month was recorded at 16.96°C, placing August alongside July 2023 as the warmest month in the Copernicus dataset. The difference between the two months was just 0.01°C.
Global Temperatures Remain Exceptionally High
Copernicus has maintained detailed climate records since 1940. Scientists, however, use additional evidence such as tree rings, ice cores and coral formations to examine climate conditions over much longer periods.
Samantha Burgess of the European Centre for Medium-Range Weather Forecasts said recent global temperatures could represent some of the highest levels experienced by humans in at least 100,000 years.
Researchers attribute the long-term rise in temperatures primarily to human activities, particularly the continued burning of coal, oil and natural gas. These activities have increased global temperatures by roughly 1.4°C compared with pre-industrial levels.
Oceans Also Near Record Temperatures
Ocean temperatures remained extremely high during August, with global sea surface temperatures reaching a new daily record and matching the previous record for the warmest August.
The world’s oceans absorb more than 90% of the excess heat trapped by greenhouse gases. Rising ocean temperatures are putting additional pressure on marine ecosystems, coral reefs and communities located in coastal areas.
Above-average temperatures were observed across several already-warm regions, including parts of the Atlantic Ocean, Mediterranean Sea and tropical Pacific.
El Niño Adds to Climate Concerns
Scientists are also monitoring the strengthening El Niño weather pattern, which develops when parts of the Pacific Ocean become unusually warm.
El Niño can influence weather patterns far beyond the Pacific, increasing the likelihood of events such as heavy rainfall and flooding in some regions, drought conditions in others and heightened wildfire risks.
Researchers expect temperatures to remain elevated as the current El Niño event approaches its projected peak around December. Some climate experts believe 2027 could set a new global temperature record, while 2026 could also rank among the hottest years ever measured.
Europe and US Face Record Heat
Western Europe experienced its hottest summer on record, surpassing the previous benchmark established in 2003.
Repeated heatwaves affected daily life across several European countries, with schools temporarily closing in some areas. High temperatures also contributed to lower river levels and conditions favourable for the spread of wildfires.
Estimates from the EuroMomo monitoring platform indicated that Europe recorded more than 32,000 excess deaths between mid-July and mid-August.
The United States also experienced its hottest summer on record, according to the National Oceanic and Atmospheric Administration.
UN climate officials have continued to warn that extreme heat and other climate-related events are likely to become more frequent unless global greenhouse gas emissions are significantly reduced.
