Stackhouse Jr, Matthew Lebsock & Timothy Andrews An update on Earth's energy balance in light of the latest global observations, Nature Geoscience, 5, 691 — 696 (2012), which indicates significant adjustments to the energy balance MEASURED data shows how far we are from certainty.

Hence, the combination of the downwelling longwave reradiated back out and the shortwave energy converted to longwave radiated energy should signify a major imbalance in which the total energy balance is maintained; however, the character of the measure has now changed significantly.)

For instance, radiative transfer models (measuring heat balance) are quite well verified, and accurately predict the rise in the temperature (and hence energy) of the atmosphere as the CO2 level increases.

The authors reject the idea that one expensive measure — the practice of «firming» wind energy by balancing it with natural gas generation at every hour — is necessary in light of other low - cost options.

«Radiative forcing is a measure of the influence a factor has in altering the balance of incoming and outgoing energy in the Earth - atmosphere system and is an index of the importance of the factor as a potential climate change mechanism.

It is rapidly expanding energy use, mainly driven by fossil fuels, that explains why humanity is on the verge of breaching planetary sustainability boundaries through global warming, biodiversity loss, and disturbance of the nitrogen - cycle balance and other measures of the sustainability of the earth's ecosystem.

More importantly from a scientific point of view, DSCOVR will provide critical new insights into our rapidly changing climate, and will give scientists — for the first time — the ability to accurately measure the energy balance of our planet.

Schwartz has a nice analysis of the energy balance Good, then you realize TSI is not a measure of T «C * dT / dt = dH / dt = Q - E» and «Time constant τ varies linearly with heat capacity» The longer cycles will mix more of the ocean, thus larger heat capacity and larger time constant.

Yes that is the point of measuring it — it changes from season to season, year to year and decade to decade and drives the energy balance of the planet in fundamental ways.

As others have noted, the IPCC Team has gone absolutely feral about Salby's research and the most recent paper by Dr Roy Spencer, at the University of Alabama (On the Misdiagnosis of Surface Temperature Feedbacks from Variations in Earth's Radiant Energy Balance), for one simple reason: both are based on empirical, undoctored satellite observations, which, depending on the measure required, now extend into the past by up to 32 years, i.e. long enough to begin evaluating real climate trends; whereas much of the Team's science in AR4 (2007) is based on primitive climate models generated from primitive and potentially unreliable land measurements and proxies, which have been «filtered» to achieve certain artificial realities (There are other more scathing descriptions of this process I won't use).

What would happen to this energy balance if Trenberth had remained true to proper scientific practice and used the measured value of 232Watts / m ^ 2 instead of his contrived 238.5 Watts / m ^ 2?

That 150 C range of temperatures also covers a wide variety of terrains, and ground cover, even deep oceans, and the thermal energy flows in each of those different environments relate to the local temperature in totally different ways, so there is no relationship between the «average» global temperature (even if it was possible to measure such a number) and the energy balance of the planet.

Since this is 7Watts / m ^ 2 higher than the actual measured average and is more than a full Watt / m ^ 2 higher than any value measured in the past 31 years, if one were to criticize someone for violating science protocol it would not be Roy Spencer whose basic data and computations are readily available for scrutiny by anyone who whishes to do so; it is Trenberth for using contrived values for OLR in his energy balance computations instead of using actual physical data measured directly by satellites.

Only in this way is the energy balance determined empirically and the multitude of changes — cloud height and extent, water vapour, ozone, surface temperature, ice and snow, biology, aerosols — integrated in a comprehensible measure.
