Coronavirus Response Proves the World Can Act on Climate Change

The alarms for both COVID-19 and climate change were sounded by experts, well in advance of visible crises. It is easy to forget, but at the time of this writing, the total deaths from COVID-19 are less than 9,000 — it is the terrifying computer model predictions of much larger numbers that have alerted governments to the need for swift action, despite the disruption this is causing to everyday life.

Yet computer models of climate change also predict a steady march of increasing deaths, surpassing 250,000 people per year within two decades from now.

As scientists who have studied climate change and the psychology of decision-making, we find ourselves asking: Why do the government responses to COVID-19 and climate change — which both require making difficult decisions to avert future disasters — differ so dramatically? We suggest four important reasons.

Instinctive Fear

First, COVID-19 is deadly in a way that is frightening on an instinctive, personal level. People react strongly to mortal threats, and although the virus appears to have much lower mortality for otherwise healthy people under 60, those statistics do not quell universal personal safety fears.

The rapid bombardment of vivid detail we receive about infections, overburdened hospitals and deaths further amplifies our personal assessment of risk. Climate change has the potential to end up killing more people than COVID-19 in the long run, but the deaths are one step removed from carbon emissions, appearing instead as an increased frequency of “natural disasters.”

And the slow timescale of climate change — an incremental ratcheting up of global temperatures — allows our expectations to continually adjust as the situation gradually worsens. The abstract connections between emissions and these mortal dangers prevents global climate change from achieving the urgency that the virus has, making everyone more reluctant to accept difficult policy choices.

Fast-Moving Threat

Second, COVID-19 is a new threat that exploded into the global consciousness with obvious urgency while climate change has been on the radar for decades.

The consequences of inaction on COVID-19 loom on a timescale of weeks rather than decades away for climate change — this is not a problem for future generations, but for everyone living now. The slow, creeping awareness of the climate change threat also allowed the parallel development of professional skeptics, funded by the fossil fuel industry, who were amazingly effective at sowing doubt on the science.

There was no time for vested interests to mount similar resistance to COVID-19 policy, so governments seem to be acting on the advice of health professionals for the public good.

Clear Strategies

Third, officials from groups like the World Health Organization presented coherent and immediately actionable paths to slowing the spread of COVID-19. Governments were given a straightforward priority list of compelling their citizens to wash more, stop touching, reduce travel and go into some degree of isolation.

In contrast, the space of possible solutions to climate change is bewilderingly complex, and these solutions touch on nearly all aspects of modern life.

Even experts don’t agree on exactly what is the best way to bring down carbon emissions while minimizing economic damage. This lack of clarity has contributed to confusion and decision paralysis on the part of policymakers.

Ability for Nations to Go It Alone

And, while responses to COVID-19 require close international collaboration about public health directives, travel and borders, individual nations can take effective action to slow the spread of COVID-19 within their own borders. Even the smallest countries, like Singapore, can ensure the safety of their citizens by making an effective local response to COVID-19.

In contrast, stabilizing climate requires all nations to reduce their emissions — going it alone doesn’t work. This co-ordination problem may be the toughest hurdle of all when it comes to climate change. There are ideas of how the co-ordination problem could be addressed in stages, but they still require collaboration between an initial group of committed nations.

While the international response to COVID-19 has been criticized, it still gives us hope that strong climate change policy can be achieved if we manage to overcome the psychological handicaps that keep governments complacent.

At this point, the policy changes required to mitigate climate change appear far less disruptive — economically, socially and culturally — than the measures being taken right now to tackle COVID-19.

In fact, carbon dioxide emissions could probably be brought down dramatically through gradual increases in a global carbon price in ways that would be imperceptible in the daily lives of most people.

When the dust of COVID-19 settles, we should look back at this moment as proof that our societies are not enslaved to fate, and find strength in the demonstrated ability of modern societies to react to global emergencies.
