2020 was heavily defined by the COVID-19 pandemic, which led to global social and economic disruption, mass cancellations and postponements of events, worldwide lockdowns and the largest economic recession since the Great Depression of the 1930s. Geospatial World also called 2020 "the worst year in terms of climate change" in part due to major climate disasters worldwide, including major bushfires in Australia and the western United States, as well as extreme tropical cyclone activity affecting large parts of North America.
