Abstract This expert opinion discusses how global warming and climate change impact (i) geographic expansion of indigenous tick species; (ii) tick survival and abundance in certain areas including urban parks and gardens; (iii) seasonal tick questing activities, increasing the number of infected hosts and the probability of pathogen transmission; (iv) emergence of new tick-borne disease foci; and (v) changing epidemiological patterns and increasing incidence of tick-borne diseases in endemic foci.
