Climate Change Will Be Sudden and Cataclysmic Unless We Act Now

The speed and scale of the response to COVID-19 by governments, businesses and individuals seems to provide hope that we can react to the climate change crisis in a similarly decisive manner - but history tells us that humans do not react to slow-moving and distant threats.

Our evolution has selected the "fight or flight" instinct to deal with environmental change, so rather like the metaphor of the frog in boiling water, we tend to react too little and too late to gradual change.

But we know from multidisciplinary scientific evidence - from geology, anthropology and archaeology - that climate change is not incremental. Even in pre-human times, it is episodic, when it isn't forced by a human-induced acceleration of greenhouse gas emissions and warming.

There are parts of our planet's carbon cycle, the ways that the earth and the biosphere store and release carbon, that could trigger suddenly in response to gradual warming. These are tipping points that once passed could fundamentally disrupt the planet and produce abrupt, non-linear change in the climate.

Think of it as a game of Jenga and the planet's climate system as the tower. For generations, we have been slowly removing blocks. But at some point, we will remove a pivotal block, such as the collapse of one of the major global ocean circulation systems, for example the Atlantic Meridional Overturning Circulation (AMOC), that will cause all or part of the global climate system to fall into a planetary emergency.

But worse still, it could cause runaway damage: Where the tipping points form a domino-like cascade, where breaching one triggers breaches of others, creating an unstoppable shift to a radically and swiftly changing climate.

But as COVID-19 taught us, we need to prepare for the expected. We were aware of the risk of a pandemic. We also knew that we were not sufficiently prepared. But we didn't act in a meaningful manner. Thankfully, we have been able to fast-track the production of vaccines to combat COVID-19. But there is no vaccine for climate change once we have passed these tipping points.

We need to act now on our climate. Act like these tipping points are imminent. And stop thinking of climate change as a slow-moving, long-term threat that enables us to kick the problem down the road and let future generations deal with it. We must take immediate action to reduce global warming and fulfill our commitments to the Paris Agreement, and build resilience with these tipping points in mind.
