CLIMATE CHANGE: Extreme Heat by 2070This map depicts the areas of the world predicted to suffer from extreme heat from global warming by 2070. Humankind has lived and thrived in a moderate climate niche with a yearly average of 52 to 59 degrees Fahrenheit, but with carbon emissions continuing at projected rates, the geographical position of this climate niche will shift in the next 50 years. According to a study just released, some 3 billion people will live in areas of extreme heat by 2070 if trends continue unchecked. These brutally hot conditions currently only occur in 0.8% of the earth’s surface in the hottest parts of the Sahara Desert, but could expand to over 19% of earth’s landmass by 2070. This trend could lead to extreme climatological events and mass migrations.Source: Chi Xu, Timothy A. Kohler, Timothy M.
