Overview
Anthropogenic activities are raising carbon dioxide (CO2) levels in the atmosphere, which may adversely affect human physiology. Analysis of serum bicarbonate, calcium, and phosphorus levels from the U.S. National Health and Nutrition Examination Survey (NHANES) from 1999 to 2020 provides insights into the potential impact of elevated CO2 on human health.

- Praise: Smart technology is revolutionizing energy efficiency, with simple devices allowing users to optimize their energy consumption based on renewable availability — a small step for personal use but a leap for reducing emissions.
- Praise: Interesting insights on CO2 levels and human adaptation show we might be more resilient than we think, challenging the notion of an imminent toxic atmosphere. This could shift how we approach environmental concerns.
- Concern: There's a troubling disconnect between technology's potential and reality; without serious clean energy infrastructure, all the smart switches in the world won't save us from rising CO2 — it's a social issue, not just a tech one.
- Concern: Claiming our current CO2 levels are safe feels like wishful thinking; just because we can tolerate high levels in the short term doesn't mean it's sustainable or healthy in the long run.
