We tend to take weather forecasts with a grain of salt. Some people leave their umbrellas at home unless the probability of precipitation is over, say, 40 percent, while others keep a collapsible in their bag at all times because they don't know what to believe. We know it's raining because we are getting wet, and we know it's hot because we are sweating, but almost everything else about the weather is up for grabs.

For example, in order for us to believe that the world is getting hotter, we need statistics. Consequently, the more information you receive telling you that the weather is hot, the hotter you will feel.

Mediawise, the weather was once a boring sideshow, the particulars of which only farmers worried about. In the past 10 years, climate has been politicized.
