So as we know, climate change is associated with increased radiation flux into the Earth. In other words, the sum of (incoming shortwave radiation) - (outgoing longwave radiation) [which I will call net flux] is greater than 0.
I'm just curious though - how have all of these fluxes changed over the last 20 years? Has net flux been constantly positive over the last 20-30 years? Is it changed by El Niño? Have we seen any changes in the flux associated with the recent "slowdown" in global warming?
