The COVID-19 pandemic has made people more aware of the concept of an exponential curve, in which the rate of infection is steadily increasing similar to how the Earth’s temperature is slowly rising. One person contracting coronavirus and giving it to somebody else who then goes on to infect a third person, and so on, is an example of exponential growth. And “It’s also how climate change works. And if there’s any silver lining in this mess, it’s that the coronavirus pandemic is teaching us a valuable lesson about the perils of ignoring destructive processes—and perhaps even larger, longer-term disasters—that increase exponentially.” 
People often struggle to conceptualize the future catastrophic effects of climate change, because it’s entirely unprecedented and therefore difficult to understand (since we have no reference point to compare it to). To make it worse, we can not see or feel climate change, so the severity of the issue hasn't fully sunk in for us yet. But the pandemic is a great example of how little things can slowly add up, until the results are catastrophic and completely out of control. We've had past pandemics, such as H1N1 or the flu, so we understand how they work and what they look like. It took 67 days to reach 100,000 coronavirus cases worldwide. The second 100,000 cases took 11 days, and the third 100,000 took only four days. 
The COVID-19 pandemic might galvanize people into taking action against climate change, and help them better understand the exponential growth of harmful carbon emissions that are steadily increasing each year before it becomes too late.
