Climate Change: Deadly Heat and Humidity Surge

Global temperatures are rising due to the continued burning of carbon-based fuels, a phenomenon known as climate change. This warming trend is intensifying heatwaves, particularly in regions where high humidity combines with extreme temperatures, creating dangerous conditions. Scientists use wet bulb thermometers to measure this risk, noting that prolonged exposure to wet bulb temperatures over 95 F can be fatal, a scenario increasingly seen in areas without widespread air conditioning.

The accumulation of carbon dioxide in the atmosphere traps solar heat, leading to a cascade of environmental problems. Beyond dangerous heat and humidity, climate change contributes to increased wildfire frequency, drying out landscapes and forests. It also causes ocean water expansion, leading to rising sea levels that threaten coastal populations and economies. Estimates suggest that unchecked carbon emissions could significantly reduce global incomes by the end of the century.

While the outlook is serious, there is good news: transitioning to clean energy sources such as solar and wind power offers a viable alternative to fossil fuels. Significant progress has been made in making clean energy reliable and affordable. International agreements are in place to combat climate change, offering a path toward a sustainable future, much like historical advancements in sanitation improved living conditions.
