All siding with its infinite growth paradigm, so I'm not surprised to see you writing counter-pieces to the harsh truth, which, as it stands, is that we have a pretty much dead and severely warming ocean, daily record - breaking jet - stream related weather incidents, which in turn are caused by polar temperature anomalies of +20 C as of late.

However, I've never seen a single media article in any U.S. press outlet that covered these issues — the large - scale evidence for global warming (melting glaciers, warming poles, shrinking sea ice, ocean temperatures) to the local scale (more intense hurricanes, more intense precipitation, more frequent droughts and heat waves) while also discussing the real causes (fossil fuels and deforestation) and the real solutions (replacement of fossil fuels with renewables, limiting deforestation, and halting the use of fossil fuels, especially coal and oil.)

Temperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differentiTemperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differentitemperature changes will cause conduction / diffusion of heat that partly balances the differential heating.

Gavin, I agree completely with the standard picture that you describe, but I don't agree with the claim that ``... as surface temperatures and the ocean heat content are rising together, it almost certainly rules out intrinsic variability of the climate system as a major cause for the recent warming».
