He had been infected with tick-borne encephalitis, or TBE, a potentially deadly disease that experts say is spreading into new regions due in large part to global warming. Climate change affects ticks at every stage of their life cycle — egg, six-legged larva, eight-legged nymph, and adult — by extending the length of time ticks actively feed on humans and animals. In Austria, for example, the TBE vaccine rate is near 85 percent, Dobler said, and yet the number of human cases continues to trend upward — a sign, in his opinion, of climate change’s influence on the disease. In central and northern Europe, where for the past decade average annual temperatures have been roughly 2 degrees Celsius above pre industrial times, documented cases of the virus have been rising in recent decades — evidence, some experts say, that rising global temperatures are conducive to more active ticks.
