A Vicious Circle

One task undertaken by the European Union's Copernicus Atmosphere Monitoring Service is the recording of carbon dioxide release by wildfires. In July 2021, the monitoring service recorded that the planet's burning forests released almost 1260 megatonnes of carbon dioxide. This record value was rapidly superseded in August, when the release of the 'greenhouse gas' by wildfires reached 1.3 gigatonnes. Most of this release predictably occurred in North America and Siberia (https://www.theguardian.com/world/2021/sep/21/global-wildfire-carbon-dioxide-emissions-at-record-high-data-shows). The situation is clearly a vicious circle. The more carbon dioxide is released, the greater the impact on global heating. The hotter it gets, the more flammable swathes of the Northern hemisphere become. Forest fires are then even more likely to ignite. The amount of carbon dioxide pumped into the atmosphere, will continue to climb. And so on.

The Comma butterfly ( Polygonia c-album) gets its name from the punctuation-like mark, on the underside of its wings.
