2020 will go down in history not only as the year of COVID-19 but also of devastating wildfires. Their consequences reach out far. Harmful plume particles float over thousands of miles, as ceilometers from various countries show.
Burning forests and bushes have left swaths of destruction in Australia, Siberia, and, most recently, in Brazil and across the West Coast of the United States. Impressive photos taken from satellites show the dimension of fires and smoke over California, Oregon, and Washington. But it is not only the destruction, that worries scientists. The flames cause massive release of carbon and other harmful particles, many of them too small to be visible. Light as they are, they float around the globe.
