Editing 2500: Global Temperature Over My Lifetime

This is Randall Munroe in his role as a meticulous, conscientious presenter of scientific data.  The activities shown in Randall's lifeline, whether learning to ride a bike or even getting married, pale into insignificance when the consequences of unprecedented global average temperature rise are understood and accepted.  In particular, he shows that back in 1982, two years before Randall was born, Exxon wrote an internal report predicting the rise of global temperatures due to fossil fuel use, and 40 years later their prediction (shown as the X in a circle at the top-right) is being shown to be right on track. Unfortunately, that report was hidden and not seen until much later, and the world has been slow to respond with the urgency needed to reverse the damage being done to the planet.

The Wikipedia article {{w|global temperature record}} has some telling graphs to supplement Randall's.  This one: {{w|File:20200324_Global_average_temperature_-_NASA-GISS_HadCrut_NOAA_Japan_BerkeleyE.svg|Global Average Temperature}} is the global average temperature change for the modern era, since data started being collected regularly in 1850.  This one: {{w|File:2000_Year_Temperature_Comparison.png|2000 Year Temperature Comparison}} reconstructs 2000 years of temperatures.
