But not only is the global extent of these disease carriers expanding — so is their persistence in the regions into which they’d previously occupied. Regions that may have seen only one or two weeks out of the year in which female, Zika infected, mosquitoes were active may now experience a month or two of exposure. And regions in which the mosquito was active for only a few months may now see active, disease-bearing populations for half of the year or more.

It is this increasing duration and expansiveness of disease vector exposure that is one of the most dangerous epidemiological impacts of climate change. Not only does climate change enable the movement of diseases out of previous isolation in remote reservoirs. It also enables an ever-broadening range of transport as the areas in which disease-carrying species are adapted to live dramatically expands both in terms of space and in terms of time of exposure.

All about climate change and vectorborne diseases

All about climate change

    Numerous climate change vulnerability assessments anticipate that rising global temperatures will increase the incidence of communicable diseases including vector-borne diseases (VBDs). Transmitted by bites from infected mosquitoes and other insects (vectors) VBDs are particularly dependent on climatic factors:

    • insects have no internal control over their body temperature and as ambient temperatures rise their distribution may expand through increased reproductive rate, biting behaviour and survival;
    • humidity and the availability of water for breeding also determine vector distribution, longevity and behaviour;
    • the incubation period of pathogens within vectors is also temperature-dependent and tends to become shorter in warmer conditions; and
    • human behaviour is likely to be affected by climate change which may increase our interaction with vectors and the diseases they carry.

    Climate-sensitive VBDs in the Region

    In the WHO Western Pacific Region, important VBDs that might be affected by climate change include malaria, dengue, other arboviruses such as Japanese encephalitis, chikungunya and West Nile virus, lymphatic filariasis, plague, tick-borne diseases including tick-borne encephalitis, Lyme disease and rickettsioses, and schistosomiasis.

    Heat waves, melting ice caps and rising sea levels are nothing compared to what seems to be the most annoying outcome of global warming: swarms of giant arctic mosquitoes. As researchers at Dartmouth confirmed, warmer temperatures are a treat for mosquitoes that manage to thrive and grow bigger.
    According to Time, temperatures in the Arctic have increased at twice the global rate in the past 100 years, and the recent study found that even a minimal increment of 2 degrees Celsius can boost the mosquitoes' population up 50 percent.

    I can tell that photo is not taken in Scotland, as it has large biting insects.  When they are smaller you can fit a lot more on a foot than that!
