But that’s not at all how scientists meant it, Professor Camille Parmesan, an expert in biodiversity at the University of Plymouth in the United Kingdom said. Climate risks don’t begin at 2C, she said; it’s more like where they go from high to intolerably high.
The planet has already warmed by about 0.8C (1.7 Fahrenheit) since the late-19th century.
Some of the world’s most iconic places are also the most vulnerable, and they are already feeling the effects.
