of the incoming heat from the sun goes into heating the soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under drier
climatic conditions.6

climatic trends when taken into consideration with these factors which are, land / ocean arrangements, mean land elevation, mean magnetic field strength
of the earth (magnetic excursions), the mean state
of the climate (average global temperature), the initial state
of the earth's climate (how close to interglacial - glacial threshold
condition it is) the state
