What is it about the mosquitoes that carry malaria that prevents their spread to temperate regions? What prevents temperate-region mosquitoes from carrying or spreading malaria? Is there any danger of malaria eventually spreading to mosquito populations in climates like central Canada, where summers can be pretty miserable because of the mosquitoes?

Diseases spread by mosquitoes are particularly affected by climate change, since the insects lay their eggs in standing water, be it in puddles, ponds, lakes or tide pools. Standing water varies with rainfall, humidity and temperature, with wetter weather typically showing a greater number of mosquitoes. When a female mosquito matures, she can spread infections by drawing blood from an infected host and transmitting the illness to a different host with another bite.
