But in a few thousand years, helped by a new astronomical configuration, the climate warmed up, the ice melted, and forests replaced the frozen steppes that covered Europe, where, in places, a handful of humans hunting bison, horses and antelope, survived. The sea level has been constantly rising since then, with a spike 14,500 years ago when the waters rose 20 metres in 500 years. Melting ice released massive quantities of water, causing sea levels to rise by as much as 40 millimetres a year.
