Take a long hard look at this graphic, the longest continuous direct measurement of atmospheric carbon dioxide. This is the famous Keeling Curve from the station atop Mauna Loa, Hawaii.
Trump and the GOP are closing the observatory.

@petergleick So, only two of those data points are from the Mauna Loa Observatory? Am I missing something? Powerful visual for climate change generally, but not a great graphic selection to defend the observatory itself. Why not build the chart using readings taken exlusively from this observatory?
I appreciate that it takes all sorts of data points to arrive confidently at these ones, and I believe climate change is largely manmade. I just don't think is going to sway anyone new.
Besides, the X axis is not at the zero of the Y axis.
It must be that the target audience of this graph excludes me.
@vnikolov @GrandTheftUrkel @petergleick I would seriously question this graph if the y axis started at 0, given that a zero value would never occur. The graph shows plausible ranges. Not every plot should start at 0. More than anything, one should consider whether the effect size is relevant.
