Malaria's main source of transmission is from mosquitoes, and one of the trends we're seeing from Global Warming and the ensuing Climate Change is that as snowpacks melt and the average temperature of higher elevation areas rise, the habitat there becomes more favorable for insects.  So one of the things computer models and scientists have predicted is larger insect populations, and more migrations of insect species beyond their original habitats.

As Africa has a very serious malaria problem, it is conceivable that malaria-carrying mosquitoes transported by ship or plane may be able to multiply and spread north from the Mediterranean into Turkey and from Italy into Slovenia or France, and with the larger numbers, be able to start epidemics or higher infection rates in some European populations as well.

Malaria is spread by mosquitoes that breed well in warm and humid climates. Due to global warming the average temperature in Europe has increased by around .8 degree Celsius during the last century and is anticipated to rise by 3.5 degree Celsius by 2100. With an increase in temperature, humidity increases and it also makes the breeding cycle of mosquitoes faster and makes them lay more eggs.

As a result, the mosquito population is anticipated to rise, as this will increase the incidents of the illnesses that are spread by mosquitoes. Incidents of malaria in European nations like Azerbaijan, Tajikistan and Turkey have already begun to go up. And according to predictions this is going to spread to other countries in Europe too.
