Global average temperature is lower during glacial periods for two primary reasons: 1) there was only about 190 ppm CO2 in the atmosphere, and other major greenhouse gases (CH4 and N2O) were also lower 2) the earth surface was more reflective, due to the presence of lots of ice and snow on land, and lots more sea ice than today (that is, the albedo was higher).

Others include, the role of the Sun (being the main heat source), the vast oceans which cover over 70 % of the Earth's surface (and the natural factors which determine the storage and release of CO2 back into the atmosphere), water - vapour being the dominant greenhouse gas comprising 98 % of the atmosphere, the important role of low - level clouds which is thought to be a major factor in determining the natural variation of climate temperatures (P.S. Significantly, computer - models are unable to replicate cloud - formation and coverage — which again — injects bias into model).

What's lost in a lot of the discussion about human - caused climate change is not that the sum of human activities is leading to some warming of the earth's temperature, but that the observed rate of warming (both at the earth's surface and throughout the lower atmosphere) is considerably less than has been anticipated by the collection of climate models upon whose projections climate alarm (i.e., justification for strict restrictions on the use of fossil fuels) is built.

The low luminosity of the early Sun was such that the Earth's average surface temperature would have been below 0 °C from 4500 to 2000 million years ago.

Atmospheric carbon dioxide build up produces a greenhouse effect that re-radiates some of the thermal wave lengths from the Earth's surface, which would otherwise escape into space, back towards the surface and the lower atmosphere leading to the increase in average surface temperatures.

The sulfur dioxide prevented much sunlight from reaching the Earth's surface, lowering the overall temperature, and killing crops and many creatures as a result.

This may seem like a small number compared to changes in daily temperature however to put it into comparison how small global temperature changes can have a large effect, if the Earth's surface temperature was lowered by 5 ⁰ C it would be in a full ice age.

Then the most recent explanations from Rohde, Hausfather, and Mosher for Berkeley Earth adjustments seem to turn this issue upside down, arguing that their process for correcting the data is what results in the lowering of temperatures, not from recent years, but from early years when the urban heat island and corruption of surface station sites would not have yet occurred.

On any northern summer day, one can measure temperatures on earth (surface) that can range as high as +60 C, or as low as -90 C, and every temperature between those extremes can be found somewhere.

A National Research Council panel was convened to examine observed trends of temperature near the surface and in the lower to midtroposphere (the atmospheric layer extending from the earth's surface up to about 8 km).

Scientists think that Venus used to be more similar to Earth, with lower temperatures and even liquid water on the surface of the planet.

The less atmosphere the less consistent the surface temperature of earth will be (the difference between the lowest and highest temperature will be greater).

This is one reason why the greybody temperature of the earth is lower than the surface temperature.

Warm water on Mars, boils - it's lacks atmospheric pressure lowers the boiling point to somewhere around 5 to 10 C. And 5 C water would not boil on Mars, but it would evaporate quicker on Mars then it does on Earth - because no where on Earth is drier than Mars [due to changing temperatures, frost does form on the Mars surface at equator and at nite - this requires the thin Mars air to become saturated - but generally very dry.

These take advantage of the remarkable stability of the earth's temperature near the surface and then use that as a source of heat in the winter when the air temperature is low and a source of cooling in the summer when the temperature is high.

The more ice there is at the poles, the more of the Earth's surface is white, reflecting more of the sun's light and heat and lowering temperatures further.

It is easy to see that the spectrum of outgoing IF at CO2 and water vapor absorption wave lengths are lower than what would be expected from the surface temperature of the earth.

As the Earth's surface cools further, cold conditions spread to lower latitudes but polar surface water and the deep ocean can not become much colder, and thus the benthic foraminifera record a temperature change smaller than the global average surface temperature change [43].

Or borehole temperatures with which one estimates surface temperatures, but where heat diffusion into the lower layers of the earth involves a progressive, laregely linear, loss of resolution with depth — which will also be dependent upon geological factors.

We have two new entries to the long (and growing) list of papers appearing the in recent scientific literature that argue that the earth's climate sensitivity — the ultimate rise in the earth's average surface temperature from a doubling of the atmospheric carbon dioxide content — is close to 2 °C, or near the low end of the range of possible values presented by the U.N.'s Intergovernmental Panel on Climate Change (IPCC).

It has been agreed to use a composite of RSS and UAH lower troposphere temperature — close to the earth's surface.

In the case of the Earth that is where the atmospheric temperature is about -18 C which occurs at about 4.5 kilometres up from the surface but that is a low level and within the troposphere which is the lowest segment of the atmosphere.

Second, because they also reflect sunlight, they have a dimming effect, lowering the earth's surface temperature.

Even if this hypothesis was at first founded upon assumptions for the absorption of carbon dioxide which are not strictly correct, it is still an open question whether an examination of the «protecting» influence of the higher atmospheric layers upon lower ones may not show that a decrease of the carbon dioxide will have important consequences, owing to the resulting decrease in the radiation of the upper layers and the increased temperature gradient at the earth's surface.

Without this greenhouse effect, the average surface temperature would be 255 degrees kelvin -LRB--18 degrees Celsius or 0 degrees Fahrenheit); a temperature so low that all water on Earth would freeze, the oceans would turn into ice and life, as we know it, would not exist.

... he realized the extreme complexity of the temperature control at any particular region of the earth's surface, and also that radiative equilibrium was not actually established, but if any substance is added to the atmosphere which delays the transfer of low temperature radiation, without interfering with the arrival or distribution of the heat supply, some rise of temperature appears to be inevitable in those parts which are furthest from outer space.
