Mosquito
Mosquito-borne diseases are currently most prevalent in East Africa, Latin America,  Southeast Asia, and India; however, emergence of vector-borne diseases in Europe have recently been observed. A weighted risk analysis demonstrated associations to climate for 49% of infectious diseases in Europe including all transmission routes. One statistical model predicts by 2030, the climate of southern Great Britain will be climatically-suitable for malaria transmission "Plasmodium vivax" malaria for 2 months of the year. By 2080 it is predicted that the same will be true for southern Scotland.
Bat
White nose syndrome is a condition associated with the deaths of millions of bats in the Eastern United States and Canada. The disease is named after a white fungus, "Pseudogymnoascus destructans", found growing on the muzzles, ears, and wings of afflicted bats. The fungus is mostly spread from bat to bat, and causes the disease. The fungus was first discovered in central New York State in 2006 and spread quickly to the entire Eastern US north of Florida; mortality rates of 90–100% have been observed in most affected caves. New England and the mid-Atlantic states have, since 2006, witnessed entire species completely extirpated and others with numbers that have gone from the hundreds of thousands, even millions, to a few hundred or less. Nova Scotia, Quebec, Ontario, and New Brunswick have witnessed identical die offs, with the Canadian government making preparations to protect all remaining bat populations in its territory. Scientific evidence suggests that longer winters where the fungus has a longer period to infect bats result in greater mortality. In 2014, the infection crossed the Mississippi River, and in 2017, it was found on bats in Texas.
