English: Climate change is causing multiple wildfire crises around the world and putting biodiversity at risk. According to a new study led by researchers of the University of Melbourne, a significant increase in wildfire activity is putting more than 4,400 species across the globe at risk. These include birds, mammals and many plants already at risk of extinction. Researchers also identified three major man-made drivers (global climate change, land-use and biotic invasions) behind the increase in fire activity which are having a devastating impact on biodiversity. The consequences of the bushfires from the last austral summer are visible in this image acquired on 25 November 2020 by one of the Copernicus Sentinel-2 satellites. It shows Kangaroo Island, one of the most biodiverse islands of Australia, where 210,000 hectares of land, nearly half of the area of the island, burned down. Additionally, the islands kangaroo population was almost decimated by the fires which raged from December 2019 to January 2020. With a revisit time of five days on average at the equator, the Copernicus Sentinel-2 satellites deliver free and open data which can be used to monitor wildfires and their impact on land and vegetation.
