The broiling summer of 2023 was the hottest in the Northern Hemisphere in more than 2,000 years, a new study found.
When the temperatures spiked last year, numerous weather agencies said it was the hottest month, summer and year on record. But those records only go back to 1850 at best because it's based on thermometers. Now scientists can go back to the modern western calendar's year 1, when the Bible says Jesus Christ walked the Earth, but have found no hotter northern summer than last year's.
