This is only indirectly linked to Arctic sea ice, and something I found out today, but a little over two months ago emeritus Professor of Physics at the University of Colorado at Boulder, Albert Allen Bartlett, passed away at the age of 90.
Bartlett was famous for the following quote: "The greatest shortcoming of the human race is our inability to understand the exponential function." This quote was part of a talk called Arithmetic, Population and Energy that he gave 1,742 times in 49 states and seven other countries. At the time, back in 1969, when Bartlett first held his talk,
world population was about 3.7 billion.
You might have been behind one of the 5 million views on Youtube, but if you haven't, I highly recommend watching the talk, appropriately called "the most important video you'll ever see":
People like Bartlett produce people like Bartlett.
