Many still do not see any relationship between the current COVID19 / SARS-CoV-2 pandemia and climate change. However, several warnings have been issued since many years, but largely ignored. Here a brief reminder on Twitter: https://twitter.com/StephanSavarese/status/1244430238534250498

This post is a reply to a journalist who thinks there had been no warnings: in fact, there have been several recent warnings about increased risk of pandemia, with precise evaluation of the number of people at risk, such as the one shown in this graphics presented at COP23 in 2017, quoting a paper from 2001.
