Warming Certainty
New studies find that it is now almost impossible to limit global warming to less than 2 degrees Celsius (3.6 F) by the end of the century.
Scientists at the University of Washington calculated the effects of the world’s population growth, the GDP per person and amount of carbon emitted in economic activity.
They then projected that there is only a 5 percent chance Earth will warm by less than 2 degrees by 2100.
A University of Colorado at Boulder study also found that a 2-degree warming this century is now “baked in.”
This threatens to surpass the amount of warming scientists have warned could trigger catastrophic sea level rise, as well as extreme weather events like heat waves, floods and drought.
