Earth recorded its hottest year ever in 2024, with such a big jump that the planet temporarily passed a major climate threshold, several weather monitoring agencies announced Friday. Last year’s global average temperature easily passed 2023’s record heat and kept pushing even higher. It surpassed the long-term warming limit of 1.5 degrees Celsius (2.7 degrees Fahrenheit ) since the late 1800s that was called for by the 2015 Paris climate pact, according to the European Commission’s Copernicus Climate Service, the United Kingdom’s Meteorology Office and Japan’s weather agency. The European team calculated 1.6 degrees Celsius (2.89 degrees Fahrenheit) of warming. Japan found 1.57 degrees Celsius (2.83 degrees Fahrenheit) and the British 1.53 degrees Celsius (2.75 degrees Fahrenheit) in releases of data coordinated to early Friday morning European time. American monitoring teams — NASA, the National Oceanic and Atmospheric Administration and the private Berkeley Earth — were to release their figures later Friday but all will likely show record heat for 2024, European scientists said. The six groups compensate for data gaps in observations that go back to 1850 — in different ways, which is why numbers vary slightly. “The primary reason for these record temperatures is the accumulation of greenhouse gases in the atmosphere” from the burning of coal, oil and gas, said Samantha Burgess, strategic climate lead at Copernicus. “As greenhouse gases continue to accumulate in the atmosphere, temperatures continue to increase, including in the ocean, sea levels continue to rise, and glaciers and ice sheets continue to melt.” Last year eclipsed 2023’s temperature in the European database by an eighth of a degree Celsius (more than a fifth of a degree Fahrenheit). That’s an unusually large jump; until the last couple of super-hot years, global temperature records were exceeded only by hundredths of a degree, scientists said. The last 10 years are the 10 hottest on record. July 10 was the hottest day recorded by humans, with the globe averaging 17.16 degrees Celsius (62.89 degrees Fahrenheit), Copernicus found. By far the biggest contributor to record warming is the burning of fossil fuels, several scientists said. A temporary natural El Nino warming of the central Pacific added a small amount and an undersea volcanic eruption in 2022 ended up cooling the atmosphere because it put more reflecting particles in the atmosphere as well as water vapor, Burgess said. Alarm bells are ringing “This is a warning light going off on the Earth’s dashboard that immediate attention is needed,” said University of Georgia meteorology professor Marshall Shepherd. ”Hurricane Helene, floods in Spain and the weather whiplash fueling wildfires in California are symptoms of this unfortunate climate gear shift. We still have a few gears to go.” “Climate-change-related alarm bells have been ringing almost constantly, which may be causing the public to become numb to the urgency, like police sirens in New York City,” Woodwell Climate Research Center scientist Jennifer Francis said. “In the case of the climate, though, the alarms are getting louder, and the emergencies are now way beyond just temperature.” There were 27 weather disasters in the United States that caused at least $1 billion in damage, just one fewer than the record set in 2023, according to NOAA. The U.S. cost of those disasters was $182.7 billion. Hurricane Helene was the costliest and deadliest of the year with at least 219 deaths and $79.6 billion in damage. “In the […]
