Climate change may have driven the emergence of SARS-CoV-2, the virus that causes Covid-19, a new study claims. UK researchers say global greenhouse gas emissions over the last century have driven growth of forest habitat favoured by bats. This has made southern China, in particular the Chinese Yunnan province, a ‘global hotspot’ for bat-borne coronaviruses like SARS-CoV-2. Bats act as reservoirs of numerous zoonotic viruses, including SARS-CoV, MERS CoV and the Ebola virus. It’s been thought the SARS-CoV-2 virus originated from bats, although scientists are still debating the origins of the disease, which may not ever be officially confirmed. World Health Organisation investigators admitted this week that their research mission in Wuhan will not reach its goal of revealing how coronavirus jumped from animals to humans. It is likely to have its ancestral origins in a bat species but may have reached humans through an intermediary species, such as pangolins – a scaly mammal often confused for a reptile. Estimated increase in the local number of bat species due to shifts in their geographical ranges driven by climate change since 1901.
