It is the big surprise of the Paris talks: the growing acceptance of a call from small nations most vulnerable to climate change
for the conference to declare warming should be halted at 1.5 degrees Celsius. Even a few months ago, this seemed unimaginable. Two degrees was the only target on the table. But here it has gained momentum with more than 100 nations, including the U.S. and the EU, agreeing it should be in the final agreement. With more than a day of talks remaining, inclusion is far from a done deal. But it has strong support. A 1.5-degree target “looks much more scientifically justifiable,” said Johan Rockström, director of the Stockholm Resilience Institute.
