Extreme Heat and Its Impacts

The video explains how the heat index, a combination of temperature and humidity, affects human health and safety. It highlights the increasing danger of heat-related events due to climate change, with projections of extreme heat conditions in the future. The video discusses the potential impacts on vulnerable populations and the necessity of air conditioning. It also emphasizes the importance of reducing greenhouse gas emissions and transitioning to zero-carbon energy to mitigate these risks.
