apparently the black death plague followed a similar period of warming as ours, and hotter than normal summers in northern countries allowed for rattus norvegicus [brown rat] to be displaced by rattus asiatus [black rat], the plague bearer. maybe this will get written into the walking dead somehow. yo kirkman, call me.

"Global climate change is particularly troubling, as it will lead to the latitudinal expansion of vectors [i.e. mosquitoes, fleas, etc.], permitting the proliferation of various infective agents in human populations... In the case of malaria, increasing temperatures will also increase the biting rate of the vectors, and even the incubation rate of the plasmodium itself, intensifying the burden of disease on affected populations. It is certainly reasonable to suspect that climate change may also result in the emergence of novel pathogenic agents that may thrive in warmer and wetter environments." - Andrew Price-Smith

Giant Virus Resurrected from Permafrost After 30,000 Years
Mar 14, 2014

A mysterious giant virus buried for 30,000 years in Siberian permafrost has been resurrected. The virus does not closely resemble any known pathogens.

The new discovery raises the possibility that as the climate warms and exploration expands in long-untouched regions of Siberia, humans could release ancient or eradicated viruses. These could include Neanderthal viruses or even smallpox that have lain dormant in the ice for thousands of years.

"There is now a [possibility] that the pathogenic microbes that bothered [ancient human populations] could be revived, and most likely infect us as well," study co-author Jean-Michel Claverie, a bioinformatics researcher at Aix-Marseille University in France, wrote in an email. "Those pathogens could be banal bacteria (curable with antibiotics) or resistant bacteria or nasty viruses. If they have been extinct for a long time, then our immune system is no longer prepared to respond to them."

Because the permafrost was layered along steep cliffs, drillers could extract samples from 30,000 years ago by drilling horizontally into the ice, thereby avoiding contamination from newer samples.

The team then took samples of this permafrost and put them in contact with amoebas (blob-like single-celled organisms) in Petri dishes. The researchers then waited to see what happened.

Some of the amoebas burst open and died. When the scientists investigated further, they found a virus had killed the amoebas.
