The wildfires in Australia became considerably worse in January, 2020. The disaster faced by country is far from over. Many of the fires (send) smoke high into the atmosphere and some smoke turned into pyrocumulonimbus cloud. The clouds can help a fire draw in more air and shift surface winds, (result) in fire tornadoes(龙卷风). Fires have destroyed habitats for animals that (find) only in Australia, including koalas and rare birds. It will take time to fully know how much harms have done wildlife. The wildfires are expected (continue) burning for months as Australia entered its dry season.

This past year, 2019, is the hottest and driest year on record. Fires happen (regular) during the Australian dry season. However，climate and natural changes are making  the situation (bad). At least 12 million acres have been burned so far in Victoria and New South Wales alone. Smoke from the fires has made to South America. There is so much smoke that it may stay in the air for months, could have a small effect on the planet's climate.
