The article examines the nature of changes in the pressure field at the Earth’s surface around the globe during two natural climatic periods ofthe Earth’s climate system –the stabilization period andthe secondwave of globalwarming in July. The pressure fieldwas approximated by the geopotential field of the surface H0. In the northern hemisphere, no differences in the structure of the geopotential field of the H0 surface were found in the two natural climatic periods.
