2023: Earth's Hottest Year on Record

Earth experienced its hottest September on record, with temperatures 0.93 degrees Celsius (1.7 degrees Fahrenheit) above the 1991-2020 average, according to the European climate agency. This marks the warmest margin above average for a month in 83 years of records. The hot temperatures were primarily driven by persistent and unusual warmth in the world's oceans, which have been record hot since spring. Earth is on track for its hottest year on record, about 1.4 degrees Celsius (2.5 degrees Fahrenheit) warmer than pre-industrial times. Scientists express grave concern at the records being set, as rapid global warming and El Nino contribute to dangerous climate conditions.
