he year started with some disturbing images from Australia. Scorched koalas. The beginning of 2020 marked the mid-point of Australia’s 2019-2020 bushfire season, which saw a record amount of land burned in the east of the country. More than 30 people died in the bushfires, including nine firefighters. Conservative estimates suggest more than one billion mammals, birds and reptiles also perished in the flames.

Though the reasons behind every wildfire are complex, analysis found that the climate crisis likely played a role in Australia’s severe fire season. The quick-fire research published in January found that the weather conditions like those seen at the height of Australia’s fires have become at least 30 per cent more likely since 1900 as a result of human-caused climate change.

“I would say 2020 really brought home how vulnerable we are, as a global society, to even comparatively small changes in natural hazards,” Dr Friederike Otto, a co-author of the fires analysis and associate director of the Environmental Change Institute at the University of Oxford, tells The Independent.
