Between 2008 and 2010, comparing various polls (see graph), there was on average a 16% drop in the fraction of Americans who agreed with statements roughly equivalent to "global warming is happening." Since then, the data show American acceptance of the reality of climate change has been steadily rebounding, with 66% of respondents in the Yale survey agreeing that it is happening, up from a low of 57% in 2010.This is one clear example where a lot of people cannot tell the difference between "climate" and "weather", and the difference between anecdotal evidence and scientific evidence. I hate to think that if we start to get a rather cool summer next year, these same people would change their minds and start to think the other way. In other words, forget about what it looks like overall, let's just go along with the latest whims, fashion, etc...
Scientists need to tell the public that this is NOT how we decide if there is global warming or not. We do not come up with such conclusion simply by looking at ONE data point! And frankly, the average temperature for the whole summer is equivalent to one data point!
I would not be surprised if this winter becomes exceedingly cold, and people start to think "where's the global warming now?"
