And for a vegan bodybuilder who must unfortunatelly play tetris with the food sources that he choses in order to give to his body the right ammounts of aminos, restricting SPI and soy foods so much does
not make his goal any easier.There are sometimes that you need a meal thats complete with aminos and soy provides that meal with the additional benefits of lacking the saturated fats trans cholesterol and other endothelium inflammatory factors.I'm
not saying that someone should go all the way to 200gr of SPI everyday or consuming a kilo of soy everyday but some servings of soy now and then even every day or the use of SPI which helps in positive nitrogen balance does
not put you in the cancer risk team, thats just OVERexaggeration.Exercise, exposure to sunlight, vegan diet or for those who can
not something as close to vegan diet, fruits and vegetables which contains lots of antioxidants and phtochemicals, NO STRESS which is the global killer, healthy social relationships, keeping your cortisol and adrenaline
levels down (except the necessary times), good sleep and melatonin function, clean air, no
radiation, away from procceced foods and additives like msg etc and many more that i can
not even remember is the key to longevity.As long as your immune system is functioning well and your natural killer cells TP53 gene and many other cancer inhibitors are good and well, no cancer will ever show his face to you.With that logic we shouldn't eat ANY ammount of protein and we should go straight to be breatharians living only with little water and sunlight exposure cause you like it or
not the raise of IGF1 is inevitable i know that raise the IGF1 sky high MAYBE is

not talking about external hormones and things like this.Stabby raccoon also has a point.And even if you still worry about the consumption of soy... http://www.ncbi.nlm.nih.gov/pubmed/21711174.

Second even if we ignore convection (and assume all warming of the atmosphere is from below, ie no incoming solar
radiation is absorbed in the atmosphere) it is
not the case that the atmosphere temperatures will «pivot» around some fixed
level (increasing below it and falling above it).
What happens at the «top of atmosphere» — the
level where outgoing
radiation leaves for space,
not itself a very easy concept — is the restoration of equilibrium, the increase in temperature that, through Helmholtz - Boltzmann at the Earth's brightness temperature 255K, restores the balance between incoming and outgoing energies.
The whole issue is that any
level above what is often called the «effective radiating
level» (say, at ~ 255 K on Earth) should start to cool as atmospheric CO2 increases, since the layers above this height are being shielded more strongly from upwelling
radiation... except
not quite, because convection distributes heating higher than this
level, the stratosphere marks the point where convection gives out and there is high static stability.
As the atmospheric opacity is increased (e.g., 2xCO2), the physical location of the TAU = 1
level will rise to a higher altitude, but the outgoing flux will still come from the TAU = 1
level since
radiation doesn't care about the geometric scale), and the TAU = 1
level will still correspond to the same temperature (since the solar input energy is unchanged).
Dr Zalasiewicz said: «Like any geological boundary, it is
not a perfect marker —
levels of global
radiation really rose in the early 1950s, as salvoes of bomb tests took place.
Adding CO2 increases the height distribution from where

level.

level radiation can
not be detected, people exposed to it are left in anguished uncertainty.
The imbalance is
not between IR absorbed and IR emitted by a layer of atmosphere, but between the incoming shortwave solar energy from space and the outgoing longwave energy emitted to space, due to the increasing difference between the ground temperature and the temperature of the
level from which re-emitted
radiation can escape to space.
The downward
radiation to the surface increases mainly because the low
level air temperature increases,
not because of the direct effect of increased CO2 in the air.
What I meant was that Planck
radiation increases with body or amb ient temperature, but higher temperature, per the Boltzmann distribution, makes it more probable that rotation, vibration, and / or electronic
levels will be excited, and therefore less likely to emit relaxation energy, though as you point out this may
not be exactly what happens physically — emission
radiation is more flat than anything with increasing temperatures.
