Climate models evaluated by the IPCC are based on the assumptions that: (1) Heat derived from the Sun is constant; (2) Heat derived from within the Earth is constant; and, (3) Anthropogenic contributions to atmospheric warming stem mainly from heat retention by CO2 and other greenhouse gases. Geophysical evidence of variable earthquake activity and geological evidence of variable submarine volcanism presented here indicate that heat added to the oceans is variable. The increasing occurrences of earthquakes of magnitudes ≥6 and ≥7 during 1973-2015 indicate volcanic activity is increasing and therefore Earth-heat, as well as volcanic CO2 additions, is increasing. Moreover, increased heat additions to the ocean act to decrease seawater solubility of CO2, ultimately releasing additional CO2 to the atmosphere. Furthermore, increasing submarine volcanic activity implies increasing ocean acidification, but data are insufficient to make quantitative estimates. The validity of IPCC evaluations and assessments depends critically upon due consideration being given to all processes that potentially affect Earth’s heat balance. In addition to the geological and geophysical processes discussed, the scientific community, including IPCC scientists, has turned a blind eye to ongoing tropospheric geoengineering that in recent years has been occurring on a near-daily, near-global basis. Tropospheric aerosolized particulates, evidenced as coal fly ash, inhibit rainfall, heat the atmosphere, and cause global warming. Evidence obtained from an accidental air-drop release indicates efforts to melt glacial ice and enhance global warming. By ignoring ongoing tropospheric geoengineering, IPCC assessments are compromised, as is the moral authority of the United Nations.
