Fever increases the body's set temperature (range of temperature in which body systems can function normally) to assist the immune system by activating immune cells to attack the foreign invader, such as a bacterial infection.

If one plots temperature as a function of pressure for a sequence of increasing tau, the phenomenon is immediately apparent in cases where the upper level solar absorption is sufficiently strong.

Trends as a function of CSD, Saturation: If the temperature varies monotonically over the distance from which most of the radiation reaching that level is emitted, then increasing the CSD will bring the upward and downward fluxes and intensities (at a given angle) toward the same value, reducing the net intensities and fluxes, until eventually they approach zero (or a nonzero saturation value at TOA).

Re 392 Chris Dudley — I don't understand what you mean by R ^ 2T ^ 4 — and there should be something about how optical depth is proportional to R, and also, if you're going a significant distance toward the center of such an object, there is the issue of spherical geometry; if the optical thickness is large enough across small changes in radius, then you don't need to account for the spherical geometry in the calculation of the flux per unit area as a function of the temperature profile and optical thickness; however, the flux per unit area outward will drop as an inverse square, except of course within the layers that are being heated through a different process (SW heating for a planet, radioactivity, latent and sensible heat loss associated with a cooling interior, gravitational potential energy conversion to enthalpy via compression (adiabatic warming) and settling of denser material under gravity (the later both leads to compression via increased pressure via increased gravity within the interior, and also is a source of kinetic energy which can be converted to heat)...

This build up of energy increases the temperature of the atmosphere, which then causes water vapor to increase as the amount of water vapor in the atmosphere is a function temperature.

This is also consistent with the bonchardi mechanism mode, which fairly consistently indicates we can expect a reversal of ambient air temperature increase with the next day, as the dual modality of reverse recapture recombination functions as an equalizer, and the increase in low level re radiation acts as a «heat shield» keeping more air from reaching and warming the ground, allowing ice to reformulate, while most of the temporary heat, which will largely be offset by the Atlantic shift paradigm anyway, given the lower absolute percentage of (so called?)

But, just in case you were semi-serious: With oceans covering 70 % of the earth's surface, you could never change atmospheric humidity — water vapor pressure is a function of atmospheric temperature, increasing as temperature rises.

If huge emissions of CO2 are not driving temperature increases, then the apparent cooling must be a function of more powerful forces, such as described in this latest peer - reviewed study.

It is a transient function: if the temperature of the ocean increases, more CO2 is entering the atmosphere, but as the CO2 pressure increases, the influx is reduced and outflux enhanced and dCO2 / dt reduces ultimately to zero, that is when: ΔpCO2 = k (T - T0)

Changing climatic variables relevant to the function and distribution of plants include increasing CO2 concentrations, increasing global temperatures, altered precipitation patterns, and changes in the pattern of «extreme» weather events such as cyclones, fires or storms.

Percent change in zonally - averaged cloud cover over the oceans as a function of latitude and height in response to an instantaneous quadrupling of CO2, decomposed into two parts: (a) a fast adjustment that occurs before surface temperatures have warmed appreciably, and (b) a part that scales linearly with the warming of surface temperature as the system adjusts to the increase in CO2.
