Health Dangers of Climate Change

Published by DonDavidson on

When I wrote about climate change in my first book, Beyond Blind Faith, I talked about the danger climate change poses through the spread of diseases, which is one of the “birth pangs” Jesus talked about in Luke 21:10-11.[1] But climate change also poses health threats resulting from excessive heat, such as what many parts of the American South and Southwest have been experiencing this summer.[2]

One such threat is that of heatstroke, a life-threatening condition that happens when the body’s core temperature exceeds 104° F and normal cooling functions such as sweating shut down, preventing the body from cooling itself. The threat of heatstroke is especially dangerous for people who normally work outside, such as delivery drivers,[3] construction workers, and farm workers. The U.S. Bureau of Labor Statistics reports that almost forty workers die from heat each year, a statistic that is almost certainly too low because it fails to include deaths due to causes such as cardiac arrest and respiratory failure which may be heat-related.[4] In addition, heat stress and dehydration can impair decision-making and risk aversion, which in turn can result in injury and death.

A long-term effect of working in high heat over many years is Chronic Kidney Disease of Non-traditional Origin, also known as Mesoamerican Nephropathy. This disease causes progressive kidney damage, eventually resulting in kidney failure. The disease was first diagnosed in El Salvador among its sugarcane workers, but has now been observed in many other locations, including the United States. As we would expect, incidents of the disease are increasing as the planet continues to get hotter.

These problems will only get worse as climate change makes excessive summer heat more frequent and more severe. Our world already averages 2.7° F hotter than in pre-industrial times, and the current forecast is for average world temperatures to be almost 5° F warmer by 2200.
