This finding comes from a new study by the American Public Transportation Association (APTA). Travel by public transportation is far safer than car travel. Intercity and commuter passengers have about one-20th, urban rail and bus passengers about one-30th, per billion passenger-miles as car travel. Public transit-oriented communities have less than a fifth the total (pedestrian, cyclist, automobile and transit passenger) per capita traffic fatality rates as in automobile-dependent communities.

This isn't the first time climate change has threatened civilisation. Many scientists speculate that devastating environmental changes caused by climate change are largely to blame for disappearance some famous past civilisations. The decline in Ancestral Puebloans, who suddenly abandoned their distinctive homes in the Mesa Verde and Chaco Canyon villages, located on Colorado Plateau, "coincided with a prolonged drought in the San Juan Basin between 1130 and 1180.
