„If we add up all the promises to cut emissions made by countries that have signed the Paris climate agreement, the world would still warm by more than 3C by the end of this century.
ver the past three years, climate scientists have shifted the definition of what they believe is the „safe“ limit of climate change.
For decades, researchers argued the global temperature rise must be kept below 2C by the end of this century to avoid the worst impacts.
Countries signing up to the Paris agreement pledged to keep temperatures „well below 2C above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5C“.
But scientists now agree that we actually need to keep temperature rises to below 1.5C.“
