![]() State officials in Texas said that 246 people died in the storm. 17, the temperature dropped to minus 5.98 degrees in Jacksonville, Texas, far below its normal February low of about 40 degrees. The brutal arctic outburst that caused Texas’ power grid to fail and the heat wave in the Pacific Northwest last June account for many of the new records.ĭuring the winter storm, on Feb. “We will expect to see more extremes and more all-time records being set.” “We do not live in a stable climate now,” said Robert Rohde, the lead scientist at Berkeley Earth, an independent organization focused on environmental data science. Extreme-temperature events can often demonstrate the most visible effects of climate change. The world has been warming by almost two-tenths of a degree per decade. All-time heat records were set last year at 8.3 percent of all weather stations across the nation, more than in any year since at least 1948, when weather observations were first digitally recorded by the U.S. Heat waves made up most of these records. The heat and accompanying dryness also contributed to extensive wildfires in the Western United States.Temperatures in the United States last year set more all-time heat and cold records than any other year since 1994, according to a New York Times analysis of Global Historical Climatology Network data. Eastern and Central China, Pakistan and India all experienced lengthy and extreme heat waves in 2022, and monsoon floods in Pakistan ravaged much of the country. The effects of such a warm year were felt elsewhere around the world as well. Separate research has shown that heat waves in Europe are increasing in frequency and intensity at a faster rate than almost anywhere else, fueled by warming but also, most likely, by shifts in atmospheric and oceanic circulation. The Copernicus scientists said Europe had its hottest summer ever in 2022, with several heat waves rolling across the continent that set temperature records in many cities. Record-breaking regions are based on Copernicus ERA5 reanalysis models. Individual records do not reflect all weather stations that observed record temperatures in 2022. Sources: Copernicus/ECMWF NOAA Global Historical Climatology Network Records reflect the hottest year since at least 1980. “The rare event now would be to see a really cold year,” he said. ![]() Overall, the world is now 1.2 degrees Celsius (2.1 degrees Fahrenheit) hotter than it was in the second half of the 19th century, when emissions of planet-warming carbon dioxide from the burning of fossil fuels became widespread.Ĭarlo Buontempo, director of the Copernicus service, said the underlying warming trend since the pre-industrial age made 2022’s ranking in the top five “neither unexpected or unsurprising.” “They really do stand apart,” he said.Įach of the past four decades has been warmer than one that preceded it, Dr. What’s more important, he said, is that the past eight years are the warmest ever. “But ranks only tell you part of the story,” said Russell Vose, a NOAA scientist. NASA’s analysis ranked 2022 as tied with 2015 for fifth warmest, while NOAA had last year as the sixth warmest. NASA and the National Oceanic and Atmospheric Administration also issued analyses of global temperatures for 2022 on Thursday, and their findings were similar. The eight warmest years on record have now occurred since 2014, the scientists, from the European Union’s Copernicus Climate Change Service, reported, and 2016 remains the hottest year ever. The world remained firmly in warming’s grip last year, with extreme summer temperatures in Europe, China and elsewhere contributing to 2022 being the fifth-hottest year on record, European climate researchers said this week. ![]()
