Historical and projected impact of global climate change on the extrinsic incubation of <em>Dirofilaria immitis</em>

Canine heartworm disease is caused by a mosquito-transmitted filarial nematode, Dirofilaria immitis, and the observed heterogenous global distribution of D. immitis cannot be fully explained by the distribution of its vectors. Transmission of D. immitis requires maturation of larvae within the mosquito, requiring a sustained ambient temperature above 14°C. This dataset contains RStudio scripts used to take global temperature data and classify areas as having hyperendemic potential for D. immitis transmission. We used past weather records to investigate the effect of climate change on global D. immitis transmissibility since 1980 and investigated three different carbon emissions scenarios to assess the future impact of projected climate changes in the years 2040, 2070, and 2100.
