Geography. Why does global warming accelerate the spread of plague in the biosphere?

The main reason is that under the background of global warming, the weather fluctuates greatly, which will lead to natural disasters such as droughts and floods, release a large number of disease germs, lead to large-scale wildlife and livestock deaths, trigger the outbreak of various infectious diseases, and lead to large-scale catastrophic deaths.

In some mountainous areas, due to global warming, the temperature is rising year by year, which leads to the spread of bacteria to the poles.

Take malaria as an example:

Malaria is the most serious insect-borne infectious disease in the world, and about 2 million people worldwide die of malaria every year. Malaria is distributed in more than 90 countries and regions in the world, and it occurs in a vast area between 60 north latitude and 40 south latitude. Malaria endemic areas in China are mainly distributed in most areas south of 45 north latitude. As we all know, the spread and prevalence of malaria are mainly affected by the minimum critical temperature of plasmodium development in local mosquitoes. Mosquitoes breed much faster in low latitudes than in high latitudes, and global warming has expanded the breeding range of mosquitoes.

Not a professional answer, forgive me, I hope it will help you.
