The Coronavirus has shuttered about 25% of Chinese industrial production for weeks on end.
Since Chinese production and industrial activity accounts for about 1/4 of global production, 1/4 x 1/4 = 1/16 or about 6% of global production has been halted. Thus, my back of the envelope best guess has
global CO2 emissions down about 6% 👍, and globally produced aerosols down about 6% as well. Since global dimming from aerosols is thought to be between 0.25 to 1.1 C, if we take the 1 C number as an upper limit, then the Coronavirus has resulted in global warming of about 0.06 C; with regional warming over China of about 0.25 C.
Coronavirus and Climate Change: Intimate Connections
It is well known that as our planet rapidly warms, there are more disease vectors that affect human health. Diseases such as Zika Virus, West Nile Disease, Ebola, Malaria, etc. propagate faster and more severely in warmer regions. Looking at history, when Europeans went to warmer lands of long established civilizations (Incas, Aztecs, and Mayans) it was their diseases that wiped out these Indigenous populations. Immune systems of higher latitude nations (Europeans) were stronger than those of people in lower latitude regions, the latter had no immunity to diseases the invaders inadvertently brought in.
Habitat Stress Forcing Poleward Animal Migration Increases Risk of New Virus Generation
It is thought that the coronavirus originated in Wuhan’s wild animal market, perhaps moving first from bats to a small mammal and then to humans. We know that as the globe rapidly warms, many animal species are forced to migrate towards the poles in search of more optimal habitats as their existing regions become too warm and dry to continue to sustain them. This migration causes these animals to interact more with other species, and become more stressed, weakening their immune systems and increasing the probability of them becoming virus carriers and propagators.
