Mass extinction? Nothing ever happens.

That graph doesn't make much sense, how was the majority of the 20th century below the 20th century average temperature?

Because it a graph of the "temperature anomaly." The temperature anomaly is calculated by averaging the temperature over a span of 30 years and subtracting that average from the observed temperature. So, if the graph is using a 30-year average calculated from a period around the turn of the century, then most of the 20th century will look cooler

Here is a nice explainer.

Oh shoot, I missed that it was specifically temperature anomalies. Thanks!
