The graph certainly looks authoritative and consequential - doesn’t it. Sorry, but this simplistic chart is great way to manipulate highly variable data and make it tell the story you want it to.
In a way it reminds me of a facetious suggestion to make airplane crash statistics to look better by making the calculations in incidents per flight-second rather than flight-hour.
Whoever made this graph was intending to perpetrate a hoax.
That would be NASA...
And there are some problems with the data.
But there are independent measures that agree.
