Human nature often resists change. We struggle with moving from familiar surroundings to new, unknown territories. Yet, when it comes to the greatest single challenge we face today, our resistance to change will surely cause massive, uncontrollable, and unforeseeable changes.

Climate change is upon us. We know with certainty that our behavior is impacting the planet we inhabit. The last time atmospheric concentrations of carbon dioxide were this high was millions of years ago, long before Homo sapiens appeared. This places us in an entirely new era of risk, for which we have no precedent or reliable benchmark.

Climate change is the ultimate systemic risk. Its potential impacts will be global and will be disproportionately afflicted on the most vulnerable members of our civilization. Its profound disruptions will result in the indiscriminate extinction of species. Those who are most vulnerable to the changes brought on by climate change will be those who have least contributed to it.
