Q: COVID-19, climate change and skin? Are they related to each other, and if so how and why?
A: Let’s look first at COVID-19 and climate change, and see how they are and are not related.
COVID-19 was not directly the result of climate change
We have no evidence that the COVID-19 pandemic was directly caused by climate change. Our changing climate is due to an increased burden of greenhouses gases in the atmosphere, largely as a result of our combustion of fossil fuels for energy. These trapped gases are warming our planet and disrupting the usual climatic patterns. We do know that some previously tropical viruses, like Dengue and Zika, are spreading into temperate zones as a result of climate change, but this does not appear to be behind the spread of the COVID-19 coronavirus.
To quote the World Health Organization (WHO): “There is currently no conclusive evidence that either weather (short term variations in meteorological conditions) or climate (long-term averages) have a strong influence on transmission”…of COVID-19.
