Second, we examined the change in frequency of
occurrence of unusually hot,
dry or windy conditions by comparing the number of years that maximum temperature, rain - free
days or wind speed was > 1 s.d. above the mean or when minimum relative humidity was < 1 s.d. from the mean in 1996 — 2013, as compared with the number of similar events observed in 1979 — 1996.
Paleontological records indicate the
occurrence of open woodlands in a
dry inland climate at the present -
day Arctic coast in western Beringia during the Last Interglacial.
