I find this really cool, kudos to the author for trying to build up an understanding from the actual data. I find it interesting to see that the median temps in these select cities don't seem to be wandering up that much. I wonder if there is some statistical tool to analyze the slight upward angle on the linear regressions of the medians. I am surprised that these data do not show a more extreme departure. I believe that we are getting hotter temperatures, etc etc. But perhaps my observations are colored by the media on this - if I were a lizard, would I see climate change? |

I can think of three possibilities:
1. The cold days have been getting colder, and the hot days have been getting hotter. The median temperature could still be somewhat constant in this scenario if the not-too-cold and not-too-hot days have temperatures that haven't changed much.
2. Even if the cold days have stayed roughly the same temperature, spikes and outliers in the hotter temperatures could still fail to move the medians that much. Consider that the median is often used to actively reduce the contribution of outliers to the data. Then it becomes a question of whether or not those spikes and outliers are meaningful or important.
3. Climate change is just a hoax (not something I believe, but it's certainly a "possibility").
