Parts of the continent and nearby ocean were 10-20 degrees Celsius (18-36 degrees Fahrenheit) warmer than averages from 1979-2000. One of the largest contributors to this week's records is an exceptionally mild winter in the Antarctic, according to data from the Climate Reanalyzer. "A record like this is another piece of evidence for the now massively supported proposition that global warming is pushing us into a hotter future," said Stanford University climate scientist Chris Field, who was not part of the calculations. They also noted that La Nina, the natural cooling of the ocean that had acted as a counter, was giving way to El Nino, the reverse phenomenon marked by warming oceans. Scientists have warned for months that 2023 could see record heat as human-caused climate change, driven largely by the burning of fossil fuels like coal, natural gas and oil, warmed the atmosphere.

Pakistan's cricket captain Babar Azam cools off during a practice session at the National Stadium in Karachi on July 4, 2023, ahead of their test series tour in Sri Lanka. On Wednesday, 38 million Americans were under some kind of heat alert, Kapnick said. The air is so thick."īeijing reported nine straight days last week when the temperature exceeded 35 degrees Celsius (95 degrees Fahrenheit), and ordered a stop to all outdoor work Wednesday, as the temperature reached 41 degrees Celsius (106 degrees Fahrenheit). "I feel like we live in a tropical country right now," city spokeswoman Jill Sturdy said. In North Grenville, Ontario, the city turned ice hockey rinks into cooling centers as temperatures Wednesday hit 32 degrees Celsius (90 degrees Fahrenheit), with humidity making it making it feel like 38 degrees (100 degrees Fahrenheit). While some countries had colder weather than usual, high-temperature records were surpassed this week in Quebec and Peru. The entire planet sweltered for the two unofficial hottest days in human record keeping Monday and Tuesday, according to University of Maine scientists at the Climate Reanalyzer project. People sit in the shade in Havana, Cuba, July 5, 2023. Scientists generally use much longer measurements - months, years, decades - to track the Earth's warming, but the daily highs are an indication that climate change is reaching uncharted territory. And NOAA indicated it will take the figures into consideration for its official record calculations. While the figures are not an official government record, "this is showing us an indication of where we are right now," said National Oceanic and Atmospheric Administration chief scientist Sarah Kapnick.
That matched a record set Tuesday, and came after a previous record of 17.01 Celsius (62.6 degrees Fahrenheit) was set Monday. The average global temperature was 17.18 Celsius (62.9 degrees Fahrenheit), according to the University of Maine's Climate Reanalyzer, a tool that uses satellite data and computer simulations to measure the world's condition. Earth's average temperature on Wednesday remained at an unofficial record high set the day before, the latest grim milestone in a week that has seen series of climate-change-driven extremes.
