Why a Sudden Surge of Broken Heat Records is Scaring Scientists

Monday was Earth's hottest day in at least 125,000 years - and Tuesday was hotter. The Washington Post reports that the director of Europe's Copernicus Climate Change Service has a term for it: "uncharted territory."It's not just that records are being broken - but the massive margins with which conditions are surpassing previous extremes, scientists note. In parts of the North Atlantic, temperatures are running as high as 9 degrees Fahrenheit above normal, the warmest observed there in more than 170 years. The warm waters helped northwestern Europe, including the United Kingdom, clinch its warmest June on record. New data the Copernicus center published Thursday showed global surface air temperatures were 0.53 degrees Celsius (0.95 degrees Fahrenheit) above the 1991-2020 average in June... Antarctic sea ice, meanwhile, reached its lowest June extent since the dawn of the satellite era, at 17 percent below the 1991-2020 average, Copernicus said. The previous record, set a year earlier, was about 9 percent below average. The planet is increasingly flirting with a global warming benchmark that policymakers have sought to avoid - 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial levels. It has, at times, been surpassed already this year, including in early June, though the full month averaged 1.36 degrees above an 1850-1900 reference temperature, according to Copernicus.
