Paper__A tale of two crises: COVID-19 and climate

"In response to the COVID-19 pandemic, governments around the world are mobilizing unprecedented public resources to mitigate economic collapse. However, these new programs run the risk of paying insufficient attention to the multiple sustainability crises we face. Climate change, in particular, threatens the very basis for continued human prosperity and requires an equal, if not greater, societal mobilization...we argue that the response to the coronavirus outbreak also offers an opportunity to advance the climate agenda. Indeed, given that we have scarce resources at our disposal, it is essential that we synergize such efforts. We propose that this can be accomplished in two primary ways: (1) harnessing the disruptive forces of the COVID-19 pandemic to accelerate the decline of carbon-intensive industries, technologies, and practices, and (2) leveraging responses to drive low-carbon innovation. From these two strategies, we outline five principles of “sustainability transition policy” to serve as a guide during these challenging times"

Still, how is it possible to explain to climate deniers the inertia and internal variability of the climate system that explains that if all carbon dioxide emissions were reduced to zero in 2020 we would only see a reduction in the rate of warming by 2033 ?
