The numbers are in, and they aren’t looking good for climate change deniers. According to the latest reports, the cost of doing nothing on climate change, even based on moderate warming models, will top $400 trillion in economic losses.
If that figure isn’t startling enough, then consider the additional $43 trillion in damages that we’ll see in the next few decades just from the additional release of CO2 and methane from melting permafrost. That $43 trillion figure assumes all current emissions stay the same, or even fall slightly. If emissions continue to rise, that $43 trillion number is going to climb rapidly.
