all the data we can scrape out of rocks, shells and cylinders of
ice, what we really need to know, in detail on a planetary
scale, is how much energy comes in and how much goes out. That
can only be measured (even roughly) with satellites. This paper
rattles the whole table of key numbers, with empirical results.
It puts core numbers into a new perspective, numbers like the
3.7Watts per square meter that a doubling of CO2 is supposed to
add to the surface budget. The models are hunting for imbalances
and build-ups in planetary energy. But according to the
observations, the longwave (infra-red) energy coming onto the
earth’s surface, the infamous back radiation, is 10 – 17 W/m2
higher than in the famous Trenberth diagram from 1997. So the
models are trying to explain tiny residual imbalances, but the
uncertainties and unkn
