Global Warming: Just Earth Business as Usual

Shocking insights into global climate change processes stem from the average global temperature and greenhouse gas concentration records (long ice core databases). They indicate the endgame for modern civilization is a temperature induced altered equilibrium state for ocean circulation (likely to be reached within the next 100 years) and markedly colder climates in the Northern Hemisphere. The temperature record, the global heat balance over time, also indicates reducing, or totally eliminating greenhouse gas production activities, will not prevent the continuing rise to the triggering average global temperature.

Insolation cycles (Milankovitch insolation intensities) and ice core concentrations of greenhouse gases offer measures of radiant energy heating to compare with the global heat balance. The remarkable differences between very slowly changing ~100,000 year insolation cycles and the saw-toothed global temperature records, replete with major and minor abrupt trend reversals within each insolation cycle, demonstrate timing and importance of two additional energy related processes, changes in equilibrium states of ocean circulation, and related impacts on global albeto. Paleoclimate characteristics (in time and space) and radiant energy states constrain major abrupt reversals in the global heat budgets to these processes. The interglacial climatic state of three prior Milankovitch insolation cycles have been terminated abruptly at plus 2° C to 3° C temperatures above the present temperatures. The lowest (plus 2° C) was associated with the strongest insolation cycle the most rapid global warming.

Greenhouse gas concentrations are ~110 ppm above the concentration required for global heat balance (stabilized temperatures). Reducing or eliminating anthropogenic greenhouse gas emissions will not prevent a continuous global temperature rise until the critical global temperature is reached! It's “Just earth business as usual” with too much help from us.
