On the bright side, the cold is killing the invasive pythons and iguanas:

But if the extended cold threatened rare native species like turtles and the Florida manatee, it may also function as nature’s way of targeting invasive species that Florida wildlife officials, frankly, want to see gone from the state, and which have been causing a political stink for years. In fact, the cold has given wildlife officials backup in their fight against two species that came uninvited to Florida: the green iguana and the Burmese python. Officials have one message to residents who feel sorry for frozen-stiff iguanas: Don’t try to rescue them by wrapping them in towels and bringing them inside. (As “iguana girl” does.)
