Uncharted Territory only if you start your charts in the mid 19th century, at the end of the Little Ice Age. If you look at the full history, the Medieval Warm Period[0] was hotter than our current forecasts, and things got better. It ushered in global golden age for man.
Go back further and you can also include the Roman Warm Period, and the Late Bronze Warm Period. It's cyclical glacial/inter-glacial periods. Right now, we are in an inter-glacial period of an ice age. Overall, I'm enjoying the temperate weather, the longer growing seasons, and global-greening.
The wikipedia plot is based on data from the following Nature paper, from 2020: https://www.nature.com/articles/s41561-019-0400-0 , you can see that by following the reference in the link to the plot.
