Deadly Lone Star Tick's Territory Expanding Thanks to Climate Change

The territory where Lone Star ticks live is expanding. Scientists think that climate change is allowing this aggressive tick to expand its current territory.

While some believe it is the first time this tick has been seen in New England and surrounding states, others say it is just returning to its former territory. The chances are that the tick is catching rides on deer to move into its expanded territory.
