But obviously not to the degree that something dramatic has happened to the world. And a lot of assumptions presumably go into that chart, that are not shown on the chart.

Due to the gradual nature of the change to the climate in comparison to the average human lifetime and the shifting baseline of people's perceptions, many people will never acknowledge that there has been a dramatic impact.
Some people... So what. Some people actually believe in flat earth theory.
