To study the changes in the local variations of geomagnetic field, the Karadag point was chosen due to the fact that we found previously on increased insolation and the surface temperature of the earth at this point over the last century (compared to other Crimea points). For the analysis, the data calculated by the authors with a calculator of the 12th model of the International Geomagnetic Standard Field (The International Geomagnetic Reference Field — IGRF-12) were used. A polynomial model of
