WITH WESTERN GOVS TRYING TO RESTRICT MIGRATATION 2 BILLION PEOPLE COULD BE ON THE MOVE BY 2030
If the current pace of global warming goes unchecked, it will push billions of people outside the “climate niche,” the temperatures where humans can flourish, and expose them to dangerously hot conditions, according to a new study published.
The study, published in the journal Nature Sustainability, evaluated the impact on humans if the world continues on its projected trajectory and warms 2.7 degrees Celsius by the end of the century, compared to pre-industrial temperatures. Factoring in both the expected global warming and population growth, the study found that by 2030 around two billion people will be outside the climate niche, facing average temperatures of 29 degrees Celsius (84 degrees Fahrenheit) or higher, with around 3.7 billion living outside the niche by 2090. Timothy Lenton, one of the study’s two lead authors, said that one third of the global population could find themselves living in climate conditions that don’t support “human flourishing.” “That’s a profound reshaping of the habitability of the surface of the planet and it could lead potentially to large scale reorganization of where people live,” Extreme heat is also predicted to decrease crop yields, and increase conflict and the spread of disease. Scientists have long warned that warming beyond 1.5 degrees Celsius would result in catastrophic and potentially irreversible changes. As the areas within the climate niche shrink as global temperatures rise, a larger swath of the population will also be more frequently exposed to extreme weather events including droughts, storms, wildfires and heatwaves. With the British government having trouble trying to stop a few thousand crossing in small boats their future policies need to be looked at more from from the point of millions and not thousands, especially as many of the poor migrants will be from old colonial outposts.
