The global surface temperature, whether measured through traditional thermometry or modern satellite radiometry, is clearly increasing. Empirical analysis of temperature datasets show global temperatures increasing at about 0.15oC/decade, and “business-as-usual” forecasts of time to breach a 1.5oC threshold vary from 10 to 20 years, and 2.0 oC thresholds from 15 to 50 years hence. Warming primarily at the poles have reduced the meridonial thermal gradient, giving rise to loopy meridonial jets that tend to stall causing deluge or excessive heat culminating in floods or wildfire disasters such as those in Maui, Canad, Greece and California. A simple model greenhouse gas driven radiative imbalance yields a surprisingly accurate comparison with the temperature record. If left unchecked, continued reliance on fossil fuels will lead to accelerating natural disasters which will inevitably increase the on-going melt of the great ice-sheets in Greenland and the Antarctic; this could yield an Eemian-like world in a few hundred years resulting in sea-levels 5m or higher than today. Alternative energy sources such as solar, and small module nuclear are discussed which can reduce or eliminate CO2 increases. More radical strategies such solar-geoengineering to affect the solar constant may be necessary, but whether such a cure may be worse than the disease must be very carefully considered.
