Summary
Most conversations about climate change stop at fear, politics, or denial, and never make it to practical solutions. Today’s guest, Dr. David E. Comings, is determined to change that. A physician, geneticist, former director of medical genetics at City of Hope National Medical Center, and author of nearly 500 peer‑reviewed papers, Dr. Comings brings a lifetime of scientific rigor to what he calls humanity’s greatest challenge: global warming. In this episode of Marketer of the Day, Dr. Comings breaks down four key variables driving climate change: rising CO₂ levels, the accelerating rate of that rise, Earth’s massive heat imbalance (equivalent to 143,000 atomic bombs going off every day), and the warming and acidification of the oceans. He connects the dots between hotter oceans, more extreme storms, deadly heat waves, crop failures, and food insecurity, showing how these forces compound into a global crisis already claiming thousands of lives. But this isn’t just another doom-and-gloom climate episode. Dr. Comings lays out four actionable ways to fight global warming at scale. You’ll hear about restoring Earth’s albedo (reflectivity) with highly reflective surfaces in deserts, reversing ocean acidification, and using enhanced weathering, crushing specific rocks so they chemically bind CO₂ safely and permanently. He also explains why injecting carbon dioxide into basalt formations could safely store trillions of tons of CO₂, and why some popular “bury it underground” approaches may be far riskier than people realize. Dr. Comings also exposes the policy failures and missed opportunities that are making the problem worse, from governments paying companies not to build offshore wind farms, to leaders who dismiss climate science as a hoax. He contrasts this with countries…
