Warning: climate change is dangerous to your health (in case you were not sure).

Over the last few months, the momentum to address climate change has dramatically accelerated. This momentum was palpable when 400,000 people marched through the streets of New York during the United Nations Summit in September. While it was an impressive call to action—hailed as the largest climate march in the history—it is two conservative forces in society that are driving the power and urgency to address the climate crisis: the financial industry and the health sector. The investment community’s expression of concern focuses on what is known as the “carbon bubble.” The argument goes like this: Stock valuation of fossil fuel companies is based on stores of carbon that are still in ground in the form of coal, gas, and oil reserves. Through the Intergovernmental Panel on Climate Change, climate scientists have come to the consensus that we cannot exceed 21 centigrade in planetary warming, otherwise catastrophic environmental and health impacts will occur. 1 However, if fossil fuel companies exploited all the assets they own, global temperatures would rise around 51 centigrade, essentially making the planet uninhabitable. Fossil fuel companies will never be allowed to burn all of their carbon assets, but because their valuation includes every potential drop they hypothetically could pull from ground, their stocks are vastly overpriced. These assets are “stranded.” The economic and moral argument shape up quickly: Why invest in fossil fuel companies if their true value is greatly exaggerated and their actions would throw us far past internationally recognized limits of planetary warming? Mainstream investors are rapidly recognizing this. During the UN Climate Summit, more than 50 foundations, institutions, and wealthy individuals announced they would divest more than $50 billion worth fossil fuel assets. 2 Even the
