I have gone through the article, suprisingly, there was no data to backup claim that "the ticks are comming". Is that a real threat or just a mere speculation?

I have gone through the article, suprisingly, there was no data to backup claim that "the ticks are comming". Is that a real threat or just a mere speculation? I couldn't find the name of the author of the article, just to make sure it is someone who knows something about health problems. Lack of data plus IStock photos suggest that the research behind the article might not have been very thorough. For instance it would be interesting to learn what persentage of ticks carries bacteria dangerous for people, how the number of people infected was changing over the past years, etc.
