"Like all forms of climate defeatism, giving up on 1.5 degrees Celsius (2.7 degrees Fahrenheit) is a conversation for the privileged. 1.5 degrees of warming will already cause vast destruction to climate-vulnerable places, such as communities reliant upon coral reefs. For many more parts of the world, an additional 0.5 degree of warming is the difference between losing one’s house and losing one’s homeland. Unlike the climate threats faced by the wealthy, including the dignitaries and well-heeled NGO staff at COP27, the question for these communities boils down to survival, not strategy."
