Transmission of thousands of new pathogenic viruses from bats due to climate change

According to scientists, an ever-warmer climate will cause more animal species to migrate to new locations, bringing with them parasites and pathogens, and “increasing the risk of contracting diseases.” Infectious Diseases will only be transmitted from animals to humans in the next 50 years.”

When animals migrate, some species will come into contact with each other for the first time. Among them, the danger is greatest in densely populated areas, especially in tropical Africa and Southeast Asia.

The journal Nature, which published the study, believes it is one of the first to assess global changes that could create “future hotspots” for the transmission of viruses and new diseases. how floating.

The researchers, led by Colin Carlson from Georgetown University, modeled how mammals might migrate as their habitats become too hot, as the world warms by 2°C by 2°C next year. 2070.

The team of scientists predicts that there will be at least 15,000 new viruses that can be transmitted between species, mainly by bats, which often carry viruses that are highly transmissible to humans.

The World Health Organization (WHO) believes that the COVID-19 outbreak in 2020 in Wuhan is likely caused by a virus that was transmitted from bats to humans through an intermediate species.

Scientists and governments around the world agree that the world should find ways to limit warming to 1.5°C above pre-industrial levels, thereby avoiding Climate Change worst, although some effects will still occur. However, current environmental protection policies, if implemented, will cause the Earth to warm by about 1.9°C.

The main objective of the COP26 Climate Summit in 2021 in Glasgow is to “keep the temperature rise within 1.5°C to be viable” by calling on countries to review and strengthen their plans. climate action plan during the next COP27 summit in Egypt in November 2022.

Before the Paris Climate Agreement was agreed at COP21 in 2014, the world was on track to warm by nearly 4°C.
