Mathematician Believes Mankind May Be Doomed

Mathematician Dr. Fergus Simpson speculates that humanity may have a 0.2 percent chance of a global catastrophe wiping us out in any given year of the 21st century.  The University of Barcelona Institute of Cosmos Sciences scholar bases his opinion on the Doomsday Argument, which claims to be able to predict the number of future humans based on the total number of humans born to date.  The proliferation of nuclear arms and climate change are listed as the top impetuses for extinction in the study.
