The point about heating (adding energy) vs warming (temperatures going up) is a very good one — it might help if the scientists involved with the major temperature series people look at (GISS, RSS, etc) also produced a global surface energy change index that accounted for things like melting ice, which absorb heat without raising temperatures.

However, the warming trends are still lower than the surface temperature trends, and also quite surprisingly, the trends in the tropical troposphere are less warming than the trends in the extratropical troposphere.

Remember also that the US is only about 2 % of the globe and the global surface record corresponds closely with satellite measurements of the lower troposhere, and also the sea surface temperatures show a strikingly similar pattern of warming.

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.

Long term changes in the way sea surface temperatures are measured also tend to introduce warming.

Note also that the global warming trend has not been terribly strong over the last decade, so inferring a negative feedback to surface temperature change is a bit odd to me, particularly when the feedback would have to be very sensitive.

It also concludes that current northern hemisphere surface air temperatures are significantly higher than during the peak of the Medieval Warm Period (MWP).

I also think that if one wishes to prove that carbon dioxide in the atmosphere is the cause of global warming then the focus of temperature measurement should be upon those few feet between the Earth's surface and the measuring instruments employed on land for measuring that temperature.

What takes place at lower altitudes affects the relative temperatures in the atmosphere and on the surface, but as a whole the increased temperatures at a fixed height of the upper troposphere lead also to a warmer lower troposphere and surface.

East Coast winter storms, known as «nor» easters» because of the unusual northeasterly direction of the winds as the storm spirals in from the south, are unusual in that they derive their energy not just from large contrasts in temperature that drive most extratropical storm systems, but also from the energy released when water evaporates from the (relatively warm) ocean surface into the atmosphere.

World Meteorological Organization also confirmed 2017 as being among the three warmest years, and the warmest year without an El Niño, by consolidating the five leading international datasets, including HadCRUT4, which showed that overall the global average surface temperature in 2017 was approximately 1.1 ° Celsius above the pre-industrial era.

That warming on descent also reduces the rate of temperature decline with height which suppresses convection from the surface so that the surface on the day side then warms more than it otherwise would have done and the surface on the night side cools less quickly than it otherwise would have done..

The spatial mean and dispersion of surface temperatures over the last 1200 years: warm intervals are also variable intervals by Martin P. Tingley and Peter Huybers, both of Department of Earth and Planetary Sciences, Harvard.

And the lower troposphere temperatures also show warming in the Southern Ocean (latitudes 65S - 55S) while the surface temperature - based datasets both show cooling.

I also suspect that a good portion of the additional warming shown in the hybrid version of the Cowtan and Way (2013) data (versus their Krig data) comes from the Southern Ocean surrounding Antarctica, where sea surface temperatures are cooling and lower troposphere temperatures are warming.

Previous research has also shown that warmer ocean surface temperatures fuel more powerful storms.

European researchers, under the Copernicus Climate Service, using a slightly different method of analysing the surface temperature data than Nasa, also found that February 2016 was by far the warmest month on record.

It can be seen from basic greenhouse theory that greenhouse warming should amplify not only the global mean surface temperature but also any variations in the global mean surface temperature that are from non-greenhouse sources at the same rate.

«However, the detailed analysis of the numerical experiment reveals that the absence of substantial surface warming in the Circumpolar Ocean is attributable not only to the large fraction of the area covered by the oceans but also to the deep penetration of positive temperature anomaly into the oceans.»

So if you say «snow cover in 49 states is due to more moisture in the air from global warming» — then you have absolutely no idea WTF you are talking about.The air is not warm, and Sea Surface Temperatures are also running well below normal.

Tamino at the Open Mind blog has also compared the rates of warming projected by the FAR, SAR, and TAR (estimated by linear regression) to the observed rate of warming in each global surface temperature dataset.

This can be affected by warming temperatures, but also by changes in snowfall, increases in solar radiation absorption due to a decrease in cloud cover, and increases in the water vapor content of air near the earth's surface.2, 14,15,16,17 In Cordillera Blanca, Peru, for example, one study of glacier retreat between 1930 and 1950 linked the retreat to a decline in cloud cover and precipitation.18

I should also have given a more complete list of the problems with your objections: in this case your «totally unsuitable» is contradicted by three papers: Arrhenius's 1896 paper proposing a logarithmic dependence of surface temperature on CO2, Hansen et al's 1985 paper pointing out that the time needed to warm the oceanic mixed layer would delay the impact of global warming, and Hofmann et al's 2009 paper modeling the dependence of CO2 on time as a raised exponential.

The IPCC most certainly also claims water vapour warms, doing most of «33 degrees» of warming, whereas, in fact, it cools the surface by reducing the temperature gradient whilst still keeping radiative balance with the Sun.

For example, Kosaka and Xie showed than when the El Niño - related changes in Pacific ocean temperature are entered into a model, it not only reproduced the global surface warming over the past 15 years but it also accurately reproduced regional and seasonal changes in surface temperatures.

However, it has been hypothesized that warmer global sea surface temperatures can enhance the El Niño phenomenon, and it is also true that El Niños have been more frequent and intense in recent decades.

How hurricanes develop also depends on how the local atmosphere responds to changes in local sea surface temperatures, and this atmospheric response depends critically on the cause of the change.23, 24 For example, the atmosphere responds differently when local sea surface temperatures increase due to a local decrease of particulate pollution that allows more sunlight through to warm the ocean, versus when sea surface temperatures increase more uniformly around the world due to increased amounts of human - caused heat - trapping gases.25, 26,27,28

It's the only one of the seven whose growth is linear, rising by 7 % for 1.0 C of warming of the surface air temperature [SAT], and, in part for this reason, is also the only one included in the calculation of the scenarios reported in AR5 by IPCC.

The process of evaporation also requires energy from heat, and the warmer the temperatures are in the upper ocean and at the ocean surface, the more energy is available.

They are also wrong in assuming that the Sun was capable of warming the surface of Venus, Earth or other planets to the observed temperature which is then maintained by back radiation being supposedly the only process that slows such surface cooling.

Warm sea surface temperature anomalies can also warn natural resource managers where coral reefs may be in danger of bleaching.

I'm very convinced that the physical process of global warming is continuing, which appears as a statistically significant increase of the global surface and tropospheric temperature anomaly over a time scale of about 20 years and longer and also as trends in other climate variables (e.g., global ocean heat content increase, Arctic and Antarctic ice decrease, mountain glacier decrease on average and others), and I don't see any scientific evidence according to which this trend has been broken, recently.

At first glance that temperature difference between Part L1A and passive house might not seem much, but when you consider that the latter also ensures warmer surfaces (achieved through better U-values in opaque elements as well as windows), greatly reduced thermal bridges and some 20 times better levels of airtightness, the comfort levels provided by the two approaches are, frankly, worlds apart.
