It’s officially hotter than anytime since the birth of Jesus

It’s one thing to say the Northern Hemisphere summer of 2023 was the hottest of the 150 years people have been making measurements. This well-documented claim is often dismissed by skeptics of global warming who point out that Earth has a long history of temperature fluctuations. That’s why it’s important that a new paper shows last summer was actually the hottest in the past 2,000 years — and that our current temperatures are even more of an outlier than we realized.
