The article says it’s never been this hot since 1880, which I believe is when they started recording this data - it didn’t mention it was this hot then.

Do you have additional info to claim it was this temp in 1880?

They didn't have records before 1880 according to the article. So, it could have been warmer, but there is no record of it.

There have been many reconstructions of global temperatures before 1880 using a variety of temperature proxies. A nice summary in one image is given on Wikipedia [1].

They also mix proxies but superimpose temperature records from the last 150 years. A better curve would be using one set of proxy data to maintain consistency.
