How can you take "has never happened before" from that chart?

Do you have eyes?

Maybe I am using the thing wrong, but I see a little over 40years which isn't "never before" by any stretch of imagination.

The reason to be concerned about exceeding some previous maximum on a small sample is that we have some understanding about the processes.

It would be really convenient if we could somehow utilize climate change to kill off all of us that refuse to see the truth.

Unfortunately, it seems extinction is pretty indiscriminate.

No no no. We don't do snark here. :P

If this is a genuine question, 2024 is the top line on the chart.

That chart is so insane. To see the last year the orange line plus the black line) so apart from all other lines before.

The XKCD of global temperatures one that always comes to mind for me.

Yes, but whatever starting March 2023 is much more extreme than climate change in the last decades has been, it's a very different scale than even that XKCD.
