The graph to show next time denialists say global warming has stopped

How Can It Be Warming When It’s (Almost) Always Cooling?
[Via Climate Progress]

The Koch-funded Berkeley Earth Surface Temperature Study (BEST) verified three things we already knew:

  1. Recent global warming has been “on the high end.”
  2. It’s accelerating.
  3. The data won’t stop the deniers and their media allies from spreading disinformation, including the myth that it has stopped warming.

Dana of Skeptical Science has a good post on the denier’s latest spin, “Going Down the Up Escalator,” reposted below.

One of the most common misunderstandings amongst climate “skeptics” is the difference between short-term noise and long-term signal.  In fact, “it hasn’t warmed since 1998” is ninth on the list of most-used climate myths, and “it’s cooling” is fifth.


Because of normal climate oscillations, which sometimes add to the heating trend and sometimes subtract, looking at approximately decade long trends – or shorter – in pretty meaningless. They cherry pick the times warming appears slower due to these weather oscillations but ignore the times when it heats faster.

The data set above was actual;y created by some skeptical scientists. Their conclusions is that the globe is warming. And their work has separated out the true scientific skeptics from the denialists.

Because the denialists continue to attack the work of the skeptical scientists with almost exactly the same arguments they used earlier against all climate researchers.

For someone living in a Cargo Cult World, the narrative is always more important than the data. To a scientist, the data determines the narrative.
