COVID-19 impacts have highlighted the depth and unevenness of systemic social vulnerability and the compounding characteristics of contemporary development models, with direct relevance to climate change risk accumulation and its reduction . This is plain at the global level: of the estimated 119-124 million additional people induced into poverty by COVID-19 in 2020, South Asia and sub-Saharan Africa each contribute two-fifths . These are rapidly urbanising and highly climate-hazard-exposed world regions, indicating COVID-19 impacts may further concentrate risk in these regions. Within cities, COVID-19 and climate change risk and loss is concurrent by gender, race and income or livelihood, for example, when vulnerable elderly populations are simultaneously exposed to COVID-19 and heatwave risk. Globally, in 2020, about 431.7 million vulnerable people were exposed to extreme heat during the COVID-19 pandemic, including about 75.5 million during the July and August 2020 European heatwave, with an excess mortality of over 9000 people arising from heat exposure .
