A rather straightforward calculation showed that doubling the level of carbon dioxide in the atmosphere... which would arrive in the late 21st century if no steps were taken to curb emissions... should raise the temperature of the surface roughly one degree C. However, a warmer atmosphere would hold more water vapor, which ought to cause another degree or so of warming.

All the greenhouse gases absorb infrared, and they also release the infrared, so these act as blockades to the infrared, leaving the atmosphere and going off into space; and the Earth warms up to send off even more infrared from the surface in order to reach its state, sort of a steady state with regard to space.

Prevailing scientific wisdom asserts that the deceleration of circulation diminishes the ocean's ability to absorb anthropogenic CO2 from the atmosphere as surface waters warm and become saturated with CO2.

They are seen in warming of the oceans, the land surface, and the lower atmosphere.

The observed fact that temperatures increases slower over the oceans than over land demonstrates that the large heat capacity of the ocean tries to hold back the warming of the air over the ocean and produces a delay at the surface but nevertheless the atmosphere responds quit rapidly to increasing greenhouse gases.

Because the loss of CO2 from the atmosphere is temperature sensitive (higher temperature leads to more rain and more carbonate formation) but the source of the CO2 is temperature insensitive (volcanoes do not care about the surface temperatures), the whole cycle forms a net negative feedback cycle: higher temperatures will result in cooling and lower temperatures will result in warming.

These so - called «modest hyperthermals» (meaning a rapid, pronounced period of global warming) had shorter durations and recoveries (about a 40,000 year cycle) and involved an exchange of carbon between surface reservoirs into the atmosphere and then into sediment.

The thermal gradient through this layer dictates the rate of heat loss from the (typically) warmer ocean surface, to the cooler atmosphere above.

The combined effects of scattering and absorption can either cool or warm Earth's surface and the atmosphere itself.

We know the planet is warming from surface temperature stations and satellites measuring the temperature of the Earth's surface and lower atmosphere.

A relatively tiny amount of nitrous oxide could have trapped enough of the Sun's energy inside ancient Earth's atmosphere to create warm surface conditions favourable to the evolution of life.

For example, if global warming were due to increased solar output, we would expect to see all layers of the atmosphere warm, and more warming during the day when the surface is bombarded with solar radiation than at night.

i.e. the water vapour will tend to carry heat (in the form of warmed air and latent heat) higher in the atmosphere, reducing surface warming.

Once heated, the ocean surface becomes warmer than the atmosphere above, and because of this heat flows from the warm ocean to the cool atmosphere above.

ENSO events, for example, can warm or cool ocean surface temperatures through exchange of heat between the surface and the reservoir stored beneath the oceanic mixed layer, and by changing the distribution and extent of cloud cover (which influences the radiative balance in the lower atmosphere).

The gasses, released by burning of fossil fuels and land clearing among other factors, trap heat in the atmosphere and warm Earth's surface.

As a result, the surface of the Earth receives almost twice as much energy from the atmosphere than it receives from the Sun and the surface is about 30 ° C warmer than it would be without the presence of greenhouse gases.

To say it a bit worse but in modern lingo: to maintain radiative equilibrium, the planet has to put out a certain amount of heat, and if it can't radiate it out from the surface, the lower atmosphere somehow has to get warmer until there's some level that radiates the right amount.

When it is assumed that the CO2 content of the atmosphere is doubled and statistical thermal equilibrium is achieved, the more realistic of the modeling efforts predict a global surface warming of between 2 °C and 3.5 °C, with greater increases at high latitudes.

This recent slower warming in the upper ocean is closely related to the slower warming of the global surface temperature, because the temperature of the overlaying atmosphere is strongly coupled to the temperature of the ocean surface.

Absorption of thermal radiation cools the thermal spectra of the earth as seen from space, radiation emitted by de-excitation is what results in the further warming of the surface, and the surface continues to warm until the rate at which energy is radiated from the earth's climate system (given the increased opacity of the atmosphere to longwave radiation) is equal to the rate at which energy enters it.

Geoengineering proposals fall into at least three broad categories: 1) managing atmospheric greenhouse gases (e.g., ocean fertilization and atmospheric carbon capture and sequestration), 2) cooling the Earth by reflecting sunlight (e.g., putting reflective particles into the atmosphere, putting mirrors in space to reflect the sun's energy, increasing surface reflectivity and altering the amount or characteristics of clouds), and 3) moderating specific impacts of global warming (e.g., efforts to limit sea level rise by increasing land storage of water, protecting ice sheets or artificially enhancing mountain glaciers).

To bring more energy into the system, that surface warming would have to cause the top - of - the - atmosphere radiation balance to change positively, but that would add to warming, amplifying the initial perturbation and leading to a runaway instability.

In Relationships between Water Vapor Path and Precipitation over the Tropical Oceans, Bretherton et al showed that although the Western Pacific warmer surface waters increased the water in the atmosphere compared to the Eastern Pacific, rainfall was lower in the Western Pacific compared to the Eastern Pacific for equal amounts of water vapor in the atmospheric column — e.g., about 10mm / day in the Western Pacific, versus ~ 20mm / day in the Eastern Pacific at 55 mm water vapor, the peak of the distribution of water vapor amounts.
