Lessons from coronavirus and climate change: Don’t be deceived by small numbers
The flu has a death rate of around 0.1 percent in the U.S. COVID-19 has put an estimated death rate between 1 and 3.4 percent, although we won’t know the true death rate until the outbreak is over. The difference between 0.1 percent and 2 percent may not sound like much. Indeed, some people on social media have opined that a 97 or 98 percent survival rate sounds pretty good to them.
Similarly…
At 1.5 degrees C of warming, heat waves will affect 14 percent of the world’s population once every five years. At 2 degrees C, 37 percent of the world will be exposed to heat waves — 420 million more people. At 2 degrees C of warming, 61 million people more will be exposed to severe drought than if we kept warming to 1.5 degrees C. That half a degree could expose between 180 and 270 million more people to be exposed to water scarcity.
