Myth: You can avoid the effects of altitude by going straight to the Sacred Valley (Urubamba) because it is lower altitude.

Spencer + Braswell have shown that over the tropics on a shorter - term basis, the net overall feedback from clouds with warming is negative; this is largely due to an increase in reflection of incoming radiation by increased clouds with a smaller effect from the reduction of energy trapping high altitude clouds, which slow down outgoing radiation by absorbing and re-radiating energy.

Effectively the log effect is pretty much over as the air is saturated with enough CO2 to pull all of the ground origin IR out by somewhere between 30 and 100 metres altitude.

I guess you're saying there shouldn't be??? Anyway, according to the version of the greenhouse effect theory used by the climate models, the greenhouse gases should be altering this natural temperature profile by changing the rates of «infrared cooling» from different altitudes.

And if you don't think similar effects dominate in wind as higher altitudes are being reached, geothermal where the same horizontal drilling as makes fossil reserves more accessible now can be used, and tidal, with new materials and methods coming onstream, then by all means, continue to live in your vacuum tube world, getting left behind by the rest of us.

Therefore we reasoned that, by studying the experimental temperature profiles (e.g., using weather balloons), we could quantify the magnitude of the greenhouse effect for each profile at all altitudes, by subtracting the parts of the temperature profile that could be explained in terms of the thermodynamic properties of the bulk gases (i.e., nitrogen & oxygen).

The second, and most detailed, devised by John Dykema of Harvard University, would explore the effects of injecting sulphur - containing substances at an altitude of 20 kilometres — the lower reaches of the boundary with outer space (Philosophical Transactions of the Royal Society A, doi.org/xb8).

I would not however accept that this rephrasing is equivalent to AM's phrasing «water vapor condensation in any adiabatic process is necessarily accompanied by reduced air pressure» because the latter carries with it the implication that if significant condensation occurs at a fixed altitude, with no other effect such as failling rain, then there is a reduction of air pressure.

Frank Lasner has a better evaluation of the station data — sorting it by similar climate characteristics and distinquishing between areas most subject to ocean cycles, rain shadow and altitude effects.

say it has been predicted that «the average temperature in the semiarid northwest portion of China in 2050 will be 2.2 °C higher than it was in 2002,» and they report that based on the observed results of their study, this increase in temperature «will lead to a significant change in the growth stages and water use of winter wheat,» such that «crop yields at both high and low altitudes will likely increase,» by 2.6 % at low altitudes and 6.0 % at high altitudes... Even without the benefits of the aerial fertilization effect and the anti-transpiration effect of the ongoing rise in the air's CO2 content, the increase in temperature that is predicted by climate models for the year 2050, if it ever comes to pass, will likely lead to increases in winter wheat production in the northwestern part of China, not the decreases that climate alarmists routinely predict.»

The principle behind the idea is that high - altitude aerosols would cool the planet's surface by reflecting solar energy back into space, mimicking the effect of huge volcanic eruptions.

Small increases in CO2 could cause small increases in temperature by slightly raising the average altitude of outgoing radiation, but it appears negative feedback from cloud variation reduces even this small effect.

A greenhouse effect governed by scattering of IR light would also not be sensitive to a cloud temperature (or the lapse rate in general) wheras the temperature change with altitude is the key behind the existence of the traditional absorption / emission GHG effect on Earth.
