“…Florides and Christodoulides (2009) have indicated, that the time delay of CO 2 increase as a result of a temperature trigger is of the order of 500-1000 years. Other literature references (Jouzel et al, 2007;Florides et al, 2010) have shown that rapid changes in Earth's temperature linked with glaciation/interglaciation switches lasted a few thousand years. Therefore, it can be concluded that time delay of global warming is larger than several decades and can be as large as a few thousands years.…”

“…To find the rate of change of temperature with rising 2 CO C a parameter R is defined. The value of R can be obtained from the historical data of the industrial era, i.e., 0.8 K temperature rise and about 100 ppmv of CO 2 rise (Le Treut et al, 2007;Meehl et al, 2007;Florides et al, 2010). For simplicity, the total temperature rise that occurred in the industrial era is attributed only to CO 2 , thus effects of fluctuations in solar or cosmic radiation (Florides et al, 2010) during this time are neglected.…”

For simplicity, the total temperature rise that occurred in the industrial era is attributed only to CO 2 , thus effects of fluctuations in solar or cosmic radiation (Florides et al, 2010) during this time are neglected. It is further assumed, that thermal imbalance of Earth can range from 0.2 K to 1.2 K. Therefore, the total change of steady state temperature as a result of 100 ppmv CO 2 rise in the atmosphere is between 1 K and 2 K. Therefore, two extreme values of R are used in the current study: R = 0.01 K ppmv -1 and R = 0.02 K ppmv -1 .…”

“…This paper aims at filling this gap with a systematic analysis of global warming dynamics. Florides et al (2010) have recently reviewed possible causes of climate fluctuations in the past. In their work the theory claiming that the prime guilty factor behind recent temperature increases is the release of GHGs (mainly anthropogenic CO 2 ) is contrasted with the other theory claiming that the main cause of global warming originates in the fluctuations in the Sun's activities.…”

Thermal response of Earth's climate to atmospheric GHGs is delayed in time. The magnitude of time delay can significantly exceed several decades, while current thermal imbalance of Earth is likely to amount 0.6 K but it can increase to 5 K by 2100. The paper provides modelling analysis of dynamical behaviour of global warming and presents climatic hysteresis diagrams. Transient simulations reveal that time delay depends on Earth's thermal capacity and mass, and on conductive and convective heat transport. It is concluded that the effect of GHGs warms climate and simultaneously suspends the glaciation/interglaciation cycles that periodically occurred in the past.

The recent disaster in the Gulf has drawn attention to the longevity of the oil supply and what alternative to gasoline is the appropriate fuel to which we should turn. The suggestion of Methanol as a substitute for gasoline as been greatly strengthened by George Olah in his publication "Beyond Oil and Gas: The Methanol Economy". However, there remained the question of burning methanol without special attention to its method of synthesis which would not add to the CO 2 content of the atmosphere. Hydrogen has often been suggested as an alternative fuel because it burns clean. A comparison is made of Hydrogen and Methanol synthesized with hydrogen and CO 2 from the atmosphere or biomass. The cost of the methanol as prepared would be $28 to $31 per GJ. Development is needed in the method by which to obtain the CO 2 from the atmosphere in a stream. Three possible methods are outlined. Only one has been subject to detailed system analysis. However, two independent calculations give highly similar costs. Water, air and wind to produce hydrogen for electrolysis of water, are the only resources necessary to make the methanol required. Changing over to any alternative fuel will impact the Oil companies. However, a change to methanol could be a long term solution for them; whereas a trend towards electricity as the overall medium of energy would not be.

Comparison of the average mean surface air temperature around the world during 1951–1978 with that for 2010–2019 shows that the bulk of the warming is around the North Atlantic/Arctic region in contrast to the Antarctic ice sheet. Obviously, the temperature change is not global. Since there is a substantial difference between solar heat absorption between the equator and the poles, heat must be moving to the North Pole by surface ocean currents and tropical cyclones. The cold, dry Arctic air coming from Siberia picks up heat and moisture from the open oceans, making the sea water denser so that the warm water sinks slowly down to c. 2000 m. A deep-water thermohaline flow (THC) transports the excess hot (c. 18°C) water south to Antarctica. It is replaced by a cold (c. 2°C) surface water from that area. The latter quickly cool western Europe and Siberia, and glaciers start to advance in Greenland within about 10 years. The THC flow decreases in Interglacials, causing the increased build-up of heat in the Northern Hemisphere (c. 60% currently stored in the Atlantic Ocean), and the ice cover in the Arctic Ocean thaws. Several such cycles may take place during a single major cold event.
