P.S- this means we have been getting more surface warming solar radiation even though the total solar radiation (TSI) is down. Perhaps there are many types of solar cycles, measured by more than sunspots and length.
None of that changes the fact that GHGs absorb infra-red radiation. The more GHGs, the more trapped radiation. Since statistically only half would be re-emitted into space, where would the rest be going, but to heat the earth?
Really? Care to quote a per centage figure on how much IR radiation doesn't make it out because of GHGs? Do you have any idea how much energy is carried by convection rather than radiation? Like the title says- we don't even know how much we don't know.
