The COVID-19 pandemic posed a severe shock to many socioeconomic systems, resulting in substantial changes in vulnerability and exposure of people to climate risks . The disease and response measures significantly affected human health, economic activity, food production and availability, health services, poverty, social and gender inequality, education, supply chains, infrastructure maintenance and the environment. These COVID-19 impacts interact with many risks associated with climate change , often through a cascade of impacts across numerous sectors . Beyond COVID-19-related mortality and long-term COVID, mortality from other diseases , as well as maternal and neonatal mortality, increased because of disruption in health services . In addition, a rapid rise in poverty has disproportionately affected poorer countries and people , and thus increased their vulnerability. After many years of steady declines, extreme poverty increased by about 100 million people in 2020 . The effects of the pandemic increased food insecurity and malnourishment, which increased by 1.5 percentage points to around 9.9% in 2020 after being virtually unchanged for the previous five years .
