EXISTENTIAL THREAT OF CLIMATE CHANGE

NASA forecasts that parts of the world will be uninhabitable by 2050 due to climate change. Their recently published world map shows the regions in red that will become uninhabitable for humans by 2070. In less than 50 years, up to 3 billion people will likely live in climate conditions “deemed unsuitable for human life to flourish.”  At current rates of climate change impact on rising sea levels, low-lying cities will be under water. The planet is undergoing one of the most significant changes in climate since the extinction of dinosaurs.

Stanford climate scientists warn that “the likely rate of change over the next century will be at least ten times quicker than any climate shift in the past 65 million years”.
Rapid environmental change will be even more troubling for humans, plants, and animals. By 2070, more than three billion people will live in regions with an average temperature above 29c.
