Yes-we have a global change of climate but climate changes in the Arctic have increased at almost three x the rate of the rest of the world over the past few decades and are already impacting local communities thus The Arctic can play a vital part in preparing the world for what is to come
Impact on the Land and Biota As warming temperatures move northwards, associated trees, plants, wildlife and their diseases will follow Emergence of zoonotic and parasitic diseases in new areas. Projected tree line at end of century ACIA 2004 p991
The changed landscape: There are limits to how much a system as in an eco-system can be changed and still recover Beyond those limits it functions differently, and the system changes to some other state

The association between different climatic drivers and the global prevalence and geographic distribution of selected vectorborne diseases observed over the period 2008-2012. Among the vector borne diseases shown here, only dengue fever was associated with climate variables at both the global and local levels (high confidence), while malaria and hemorrhagic fever with renal syndrome showed a positive association at the local level (high confidence) IPCC ch 11 2014 Enheten Infektionssjukdomar

WHO The threat of a possible outbreak of dengue fever now exists in Europe and local transmission of dengue was reported for the first time in France and Croatia in 2010 and imported cases were detected in three other European countries In 2012, an outbreak of dengue on Madeira islands of Portugal resulted in over 2000 cases and imported cases were detected in 10 other countries in Europe apart from mainland Portugal.
Asian Tiger mosquitos future scenarios
Asian Tiger mosquito A. Albopictus an invasive species that has the potential to transmit infectious diseases such as dengue and chikungunya fever
Known distribution of A. Albopictus
Future climate suitability of A. albopictus
Conclusion Similar trends are likely in the future, with an increased risk simulated over northern Europe and slightly decreased risk over southern Europe.

(a) Swedish records of Ixodes ricinus ticks from the late 1980s to early 1990s. The smallest dots represent individual records; larger dots indicate 10 and 50 records, respectively. (b) Comparative matching of the estimated distribution of I. ricinus in Sweden (shaded area) with the northern limit of the southern boreal zone (solid line) and the northern limit of the boreo nemoral zone (dashed line). Vegetation Zone data refer to 1961 1990; tick distribution data refer to the period from the late 1980s to early 1990s. (c) Comparative matching of the estimated distribution of I. ricinus in Sweden (shaded area), showing isopleths for vegetation periods of 170 days (solid line) and 160 and 180 days (dashed lines). Vegetation period data refer to 1961 1990; tick distribution data refer to the period from the late 1980s to early 1990s. (d) Comparative matching of the estimated distribution of I. ricinus in Sweden (shaded area) with the average date of first frost (15 September; solid line). First frost data refer to 1961 1990; tick distribution data refer to the period from the late 1980s to early 1990s. (e) Comparative matching of the estimated distribution of I. ricinus in Sweden (shaded area) with snow cover of 150 days (solid line) and 125 and 175 days (dashed lines). Snow cover data refer to 1961 1990; tick distribution data refer to the period from the late 1980s to early 1990s. Jaenson et al Med Vet Entom 23, 226 237, 2009
