The probabilistic nature of predicting how likely any given climate change event like the AMOC shutting down is creating a false sense of security and skepticism.

Many climate change skeptics like to claim that Earth’s climate has been radically different at various points in its history, therefore current anthropogenic climate change is fine. Other climate change skeptics like to claim that we’re currently in an ice age, therefore warming the planet is not a bad thing. Yet others claim that this is natural and humans shouldn’t try to stop it.

What these arguments miss is that all available evidence suggests that CO2 levels and global temperatures have never changed this fast outside of mass extinctions. All available evidence strongly supports the ideas that humans released the excess CO2, that CO2 is a powerful greenhouse gas, and that human-produced CO2 is causing the planet to retain more heat. There are competing theories on how catastrophic anthropogenic climate change will be and how fast it will happen, but the broad consensus is that these drastic changes will impact both humans and the broader environment.

People argue against preventative measures to slow down anthropogenic climate change because it can harm economic growth. The attitude seems to be “we shouldn’t sacrifice profits for the polar bears”. I argue that it’s not a matter of trying to save other species, it’s about saving our own species. Given the overwhelming evidence that humans are causing climate change and that the results will involve drastic changes in climate patterns, I don’t think we’re panicking enough. For the vast majority of us who are not ultra wealthy capitalists, faster economic growth won’t matter if extreme weather events threaten our lives every year and large areas of agricultural land become unusable. We need to slow down our production and consumption and study climate change more carefully, not defund climate research and charge blindly into a future we can’t control or predict.
