CLEAN : Extreme heat: could it make some parts of the world uninhabitable?

The video discusses the significant warming over the past 20 years and its potential to become the new normal if CO2 and other greenhouse gas emissions continue. It highlights the impact of extreme heat on agriculture, animals, and food security, and the challenges of urbanization in adapting to heat. The video also addresses the vicious cycle of energy use for cooling, which increases emissions, and stresses the need for rapid reductions in greenhouse gases to limit global warming to 1.5 degrees Celsius. The importance of COP26 in achieving net-zero emissions by mid-century is emphasized.
