Frosts

Floods, violent wind storms, droughts, killing frosts, and the problems of air pollution have all, on occasion, influenced modern society.

Siberian winds can cause overnight frosts.

It is not the first time French vineyards have faced severe frosts. But many say these are among the harshest in years.

The moorhens formerly disappeared from London in winter; they are now residents throughout the year in a few of the parks where there is shelter, and during severe frosts they feed at the same table with the ornamental water-fowl.
