Influence of extreme 2022 heatwave on megacities' anthropogenic CO2 emissions in lower-middle reaches of the Yangtze River

An unprecedented heatwave hit the Yangtze River Basin (YRB) in August 2022. We analyzed changes of anthropogenic CO₂ emissions in 8 megacities over lower-middle reaches of the YRB, using a near-real-time gridded daily CO₂ emissions dataset. We suggest that the predominant sources of CO₂ emissions in these 8 megacities are from the power and industrial sectors. In comparison to the average emissions for August in 2020 and 2021, the heatwave …
