WASHINGTON – August 2023 has made history as the hottest month ever recorded on Earth. This unprecedented heat is attributed to a dangerous combination of human-caused climate change and a powerful El Niño phenomenon, according to the European climate service Copernicus.
The soaring temperatures in August contributed to what has now been identified as the hottest summer in the Northern Hemisphere. Globally, the average temperature reached 62.53 degrees Fahrenheit (16.96 degrees Celsius), just a fraction above the previous record set in July 2023. Scientists like Samantha Burgess from Copernicus explain that while this temperature is technically a tie with July’s record, the situation is alarming nonetheless.
“It is now time to stop acting surprised that our warming planet keeps getting warmer. This is occurring exactly as forecast by scientists literally decades ago,” said Andrew Dessler, a climate scientist at Texas A&M University. He emphasized that the real question is not whether heat records will continue to be broken, but rather whether society will take action to address climate change.
August’s average temperature was 1.65 degrees Celsius (nearly 3 degrees Fahrenheit) above pre-industrial levels. This is significantly higher than the 1.5 degrees Celsius (2.7 degrees Fahrenheit) threshold set by the 2015 Paris Climate Agreement. In fact, the eight hottest months on record have all occurred since July 2023, highlighting the ongoing trend of extreme heat.
Burgess noted, “Our climate system is really operating well outside the range we would have expected just a decade ago.” This summer has brought more than just high temperatures; it has disrupted everyday life, leading to school closures, overwhelmed hospitals, and infrastructure failures like melting roads and buckling train lines. As Burgess warns, conditions like these will continue to become more frequent.
Additionally, August set records for global ocean temperatures and marked the hottest recorded day in the world’s seas, underscoring the extensive impact of climate change on our planet.
The U.S. also experienced a remarkable summer, with temperatures surpassing those recorded during the Dust Bowl of 1936. The National Oceanic and Atmospheric Administration announced that the average temperature from June to August 2023 was 74.37 degrees Fahrenheit (23.54 degrees Celsius), nearly four-tenths of a degree warmer than the Dust Bowl peak.
August alone saw temperatures averaging 75.58 degrees Fahrenheit (24.21 degrees Celsius) in the U.S., with daytime highs reaching an astounding 88.56 degrees Fahrenheit (31.42 degrees Celsius). This is a clear indication that climate change is rapidly accelerating, according to climate scientist Zeke Hausfather.
While the El Niño phenomenon is contributing to the heat, scientists agree that it is the relentless burning of fossil fuels that is the primary driver of these extreme temperatures. Friederike Otto, a climate scientist at Imperial College London, explained that while El Niño can raise temperatures slightly, the main culprit remains human activity.
As the world braces for an even stronger El Niño in the coming months, experts predict that heat waves, storms, floods, and wildfires will become increasingly severe and frequent. Katharine Hayhoe, a climate scientist at Texas Tech University, warns that we may see 2026 surpassing 2024 as the warmest year on record.
“Until humanity stops burning colossal amounts of coal, oil, and gas, the pollution this causes will keep baking our planet,” said United Nations climate chief Simon Stiell. He emphasizes the urgent need to address humanity’s fossil fuel addiction to prevent catastrophic climate impacts.
