The effects of wind changes, which were found to potentially increase temperatures in the Southern Ocean between 660 feet and 2,300 feet below the surface by 2 °C, or nearly 3.6 °F, are over and above the ocean warming that's being caused by the heat - trapping effects of greenhouse gases.
Hence, relatively small exchanges of heat between the atmosphere and ocean can cause significant changes in surface temperature.
To contribute to an understanding of the underlying causes of these changes we compile various environmental records (and model - based interpretations of some of them) in order to calculate the direct effect of various processes on Earth's radiative budget and, thus, on global annual mean surface temperature over the last 800,000 years.
During El Nino events the ocean circulation changes in such a way as to cause a large and temporary positive sea surface temperature anomaly in the tropical Pacific.

Global average surface temperatures are not expected to change significantly although temperatures at higher latitudes may be expected to decrease to a modest extent because of a reduction in the efficiency of meridional heat transport (offsetting the additional warming anticipated for this environment caused by the build - up of greenhouse gases).
Indeed, there is a clear physical reason why this is the case — the increase in water vapour as surface air temperature rises causes a change in the moist - adiabatic lapse rate (the decrease of temperature with height) such that the surface to mid-tropospheric gradient decreases with increasing temperature (i.e. it warms faster aloft).
Within the troposphere and between that and the surface, convection (and at the surface, conduction and molecular mass diffusion) are also important — these also respond to changes in temperature so that an imbalance causes a temperature change that causes the imbalance to decay.
Temperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differentiTemperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differentitemperature changes will cause conduction / diffusion of heat that partly balances the differential heating.
If the surface temperature is slow to catch up to that imbalance then the energy imbalance remains large, and we can have sufficient net heating to cause much faster changes in the ice sheets than from the comparatively smaller imbalances caused by the changes in Earth's orbit associated with the glacial periods in the past.
There will be Regionally / locally and temporal variations; increased temperature and backradiation tend to reduce the diurnal temperature cycle on land, though regional variations in cloud feedbacks and water vapor could cause some regions to have the opposite effect; changes in surface moisture and humidity also changes the amount of convective cooling that can occur for the same temperature distribution.
Here we would like to try to distinguish between warming in the nocturnal boundary layer due to a redistribution of heat and warming due to the accumulation of heat... It is likely that the observed warming in minimum temperature, whether caused by additional greenhouse forcing or land use changes or other land surface dynamics, is reflecting a redistribution of heat by turbulence - not an accumulation of heat.
But the change in surface temperature would also cause a change in radiative forcing.
In 2013, the Intergovernmental Panel on Climate Change Fifth Assessment Report stated a clear expert consensus that: «It is extremely likely [defined as 95 - 100 % certainty] that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic [human - caused] increase in greenhouse gas concentrations and other anthropogenic forcings together.&raquIn 2013, the Intergovernmental Panel on Climate Change Fifth Assessment Report stated a clear expert consensus that: «It is extremely likely [defined as 95 - 100 % certainty] that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic [human - caused] increase in greenhouse gas concentrations and other anthropogenic forcings together.&raquin global average surface temperature from 1951 to 2010 was caused by the anthropogenic [human - caused] increase in greenhouse gas concentrations and other anthropogenic forcings together.&raquin greenhouse gas concentrations and other anthropogenic forcings together.»
His estimate for the surface temperature rise due to a doubling of atmospheric CO2 for the zero feedback case is 0.5 C which is further reduced to 0.3 C due to negative feedback caused by the increase in planetary clouds which is in agreement with Idso's experimental analysis to determine the planet's response to a change in forcing.
The change in the amount of total solar irradiance (TSI) reaching the Earth's surface is directly proportional to the temperature change it causes.
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.

How hurricanes develop also depends on how the local atmosphere responds to changes in local sea surface temperatures, and this atmospheric response depends critically on the cause of the change.23, 24 For example, the atmosphere responds differently when local sea surface temperatures increase due to a local decrease of particulate pollution that allows more sunlight through to warm the ocean, versus when sea surface temperatures increase more uniformly around the world due to increased amounts of human - caused heat - trapping gases.25, 26,27,28
We use a one - dimensional radiative - convective model for the atmospheric thermal structure to compute the change in the surface temperature of the earth for large assumed increases in the trace gas concentrations; doubling the N2O, CH4, and NH3 concentrations is found to cause additive increases in the surface temperature of 0.7 °, 0.3 °, and 0.1 ° K, respectively.
