Dennis Avery fails to correct Right Wing Echo Machine

Dennis Avery at the Hudson Institute pushed out a story the other day claiming that: “The atmospheric CO2 levels at Hawaii’s Mauna Loa observatory have declined since 2004.” He’s totally wrong and admitted he was, but has failed to correct this mistruth and now the story is bouncing around the right-wing media echo chamber.

Here’s the graph from the Mauna Loa observatory:

First off, how could Avery, who claims to be an “environmental economist” get this so wrong?

I’m not a scientist or an economist, but it seems to me that this graph is pretty darn clear. This is far from an innocent mistake and Avery is doing nothing to stop the echo machine. If Avery had any sense of ethics he would make sure that every single outlet who carried this blatant misrepresentation corrected him on the record.
