More interesting links below: You may well be correct in this Mq. My argument for 20 years now has been that all we have done is hold off the onset of the ice age [if we are lucky].

Their conclusion: In light of these many observations, we feel it should be obvious to all reasonable people that the former U.S. Vice President has implied much more than is scientifically justified about the future behavior of the Greenland and Antarctic Ice Sheets and their impacts on global sea level. Indeed, he has implied vastly more than is justified.

Insolation -- Incoming Solar Radiation

>>> Hydrogen fusion in the Sun creates an immense amount of energy, heating the surface to around 6000°K; the sun then radiates energy outwards in the form of ultraviolet and visible light. To simplify matters, we'll say that the total amount of solar energy received by the Earth is equal to 100 units -- think of this as 100% of the actual total, which is a rather unwieldy number (55.6 x 1023 Joules/year). help put this number in perspective, it represents about 10,000 times the amount of energy generated and consumed by humans each year. Another useful way to think of this comes from considering that the solar input amounts to 343 Watts/m2 of Earth's surface. This is a bit less than six 60 Watt light bulbs shining on every square meter of the surface, which adds up to a lot of light bulbs since the total surface area of Earth is 5.1E14 m2.

Another point worth noting in this regard is Polissar et al.'s acknowledgement that "during most of the past 10,000 years, glaciers were absent from all but the highest peaks in the Cordillera de Merida," which indicates that warmer-than-present temperatures are the norm for this part of the planet, and that any significant warming that might yet occur in this region (as well as most of the rest of the world) would only mark a return to more typical Holocene (or current interglacial) temperatures, which have themselves been significantly lower than those of all four prior interglacials. What is more, atmospheric CO2 concentrations were much lower during all of those much warmer periods, providing further evidence that it is the sun that rules the world's climate, not CO2.
