Climate change is the gravest and most complex problem impacting the planet and its people in the twenty-first century. For thousands of years the Earth’s temperature has remained within a range that makes human life possible in a biodiverse ecosystem of interdependent species. Since the dawn of the industrial era we have seen increasing alteration in temperatures as a consequence of global warming, provoked by increasing carbon dioxide emissions from the fossil energy usage that has characterized the so-called Anthropocene Era. We have gone from an atmospheric carbon dioxide concentration of 280 parts per million in the preindustrial era (reference year 1750) to around 400 parts per million in 2015, and that has produced an increase in mean temperature.
