This investigation is based on a study of two paleoclimatic curves obtained in the Urals (51–59° N, 58–61° E): i) a ground surface temperature history (GSTH) reconstruction since 800 A.D. and ii) meteorological data for the last 170 years. Temp

The results of temperature monitoring in the 300-m kun-1 well (Kunashir Island) in 2011–2015 are considered. Quasi-periodic temperature variations with an amplitude of up to 0.3°C and a variation period of 14–26 h were added from November 2011 t

Ground surface heat flux variations over the last 30000, 1000, and 150 years in the Urals were first estimated on the basis of geothermal reconstructions of ground surface temperature histories and meteorological data. The heat flux histories obtaine
