In late May I interviewed John Kotcher regarding his survey that showed physicians worldwide had a limited understanding of the climate crisis and its health effects. For example, 41% said they lacked sufficient knowledge to discuss the topic and less than half also believed the climate crisis is responsible for heat-related illnesses and increases in vector borne diseases. Since the climate crisis will pose increasingly harmful human health consequences, especially for Medicare and Medicaid beneficiaries, health professionals would be well served by understanding the physics of climate change or what is causing planetary warming. Concerning recent climate crisis-related events: North American just suffered its hottest June in recorded history; two recent studies recently concluded the climate crisis presently causes five million deaths annually and the earth’s energy imbalance approximately doubled between 2005 and 2019; and, a leaked UN Intergovernmental Panel on Climate Change report (the report is expected to be published later this year) warns a series of thresholds or tipping points may soon be crossed that will leave policy makers unable to control of limit global warming - meaning the earth will experience run away warming.
