(UPI) A digital traffic sign in Houston was apparently hacked to display apocalyptic messages warning of a climate catastrophe.
The sign, located off Waugh Drive and Allen Parkway, was spotted early Wednesday flashing messages including "Global warming at work," Warning: Hurricane Human, Triassic weather ahead and We are the asteroid.
It was unclear how the hacker gained access to the sign.
