This chart doesn't show much. If shown to Guardian warmies, they just see the past trend and assign momentum to the chart. In their minds, there is an elastic band attached to the trend line that will soon snap back the current temps to the line. That's cute.
For those with a bit more physics in them, I magnified the last part of the chart. This month had a big drop. Everything looks like we'll wipe out the trend as we go into our ice age. I'm expecting the Arctic ice volume chart soon, and it will be an increase.
By the end of the year, you'll be able to mention this at your swanky Christmas parties.
