Most scientists and climatologists agree that weird weather is at least in part the result of global warming — a steady increase in the average temperature of the surface of the Earth thought to be caused by increased concentrations of greenhouse gasses produced by human activity.

And a third found that climate - induced sea - surface temperature anomalies over the northeast Pacific were driving storms (and moisture) away from California, but the warming also caused increased humidity — two competing factors that may produce no net effect.

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.

El Niño causes higher sea level pressure, warmer air temperature and warmer sea surface temperature in west Antarctica that affect sea ice distribution.

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.

A great deal of the confusion surrounding the issue of temperature trends in the upper troposphere comes from the mistaken belief that the presence or lack of amplification of surface warming in the upper troposphere has some bearing on the attribution of global warming to man - made causes.

By the way, low clouds in darkness increase surface temperature, sort of like the inverse property of commonly understood Cosmic ray effect, not causing a cooling because there are more CR's, but rather a warming, which only low clouds in total darkness can do, so the probable CR temperature signal gets cancelled from one latitude dark vs bright region to the next.

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).

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.

Just two remarks: you keep on saying that the effect of increased cloudiness «should be warming», whereas the data shown in the article clearly show the opposite (more clouds cause lower surface level air temperatures).

Gavin, I agree completely with the standard picture that you describe, but I don't agree with the claim that ``... as surface temperatures and the ocean heat content are rising together, it almost certainly rules out intrinsic variability of the climate system as a major cause for the recent warming».

A significant northward trend (reduction of ice) in the winter - maximum ice edge is apparent, however, and appears to be caused by the gradual warming of sea - surface temperatures in the region (paper available on this if you want it).

«Firstly, as surface temperatures and the ocean heat content are rising together, it almost certainly rules out intrinsic variability of the climate system as a major cause for the recent warming»

Redistribution of heat (such as vertical transport between the surface and the deeper ocean) could cause some surface and atmospheric temperature change that causes some global average warming or cooling.

A recent slowdown in global warming has led some skeptics to renew their claims that industrial carbon emissions are not causing a century - long rise in Earth's surface temperatures.

However, it is consistent with our current understanding of the climate: ocean heat is exchanged with the atmosphere, which causes surface warming, which alters atmospheric circulation, which alters cloud cover, which impacts surface temperature.

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.

I also think that if one wishes to prove that carbon dioxide in the atmosphere is the cause of global warming then the focus of temperature measurement should be upon those few feet between the Earth's surface and the measuring instruments employed on land for measuring that temperature.

Its hard to see how the oceans can be warming dramatically due to anthropogenic causes if the sea surface temperature (controlled for ENSO, ENSO afteraffects etc) is actually relatively stable.

And that reality has been demonstrated over and over again, most recently in the work of the Berkeley Earth Surface Temperature project, led by Dr. Richard Muller, who began his comprehensive assessment as an avowed climate skeptic and ended it convinced by the clear evidence that global warming is happening and is caused by human activity.This conclusion is emphatically shared by the best and brightest of the global scientific community, including our own National Academy of Sciences.

Years - long ocean trends such as El Niño and La Niña cause alternate warming and cooling of the sea surface there, with effects on monsoons and temperatures around the world.

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.

They describe abnormally warm or cool sea surface temperatures in the South Pacific that are caused by changing ocean currents.

«With very high sea surface temperatures that have a strong global warming component, these flooding events break records, and cause untold damage,» he says.

It seems that the El Niño - related warmer sea surface temperatures in the eastern equatorial Pacific in late winter cause deep convection patterns to shift eastward.

Although he doesn't actually come out and say it, Evans suggests that the global warming trend in the surface temperature record is an artifact caused by the urban heat island (UHI) effect:

At this computer - predicted «hot spot» high above the Earth, the UN's models project that greenhouse warming will cause temperature to rise over the decades at a rate up to three times faster than at the surface.»

But to cause this «top - down warming,» the warming trends in the atmosphere would have to be more pronounced than surface warming trends, because much of the energy from atmospheric warming is lost into space and does not affect surface temperatures.

The paper discusses that melting ice will decrease the salinity of the ocean waters around Antarctica, which will cause decreased mixing with the relatively warmer deep ocean waters, reducing sea surface temperatures, causing more sea ice to form.

The value of measuring atmospheric temperatures globally becomes clear when we recall that the untested hypothesis behind global warming projects that greenhouse gas warming in the atmosphere will cause the surface to warm by 6 degrees Fahrenheit (with a probable error of plus or minus 3 degrees).

-- Increased urbanization and land use changes since WWII as a possible partial cause of warming of global surface temperature over land.

This empirical finding contradicts Spencer's hypothesis that cloud cover changes are driving global warming, but is consistent with our current understanding of the climate: ocean heat is exchanged with the atmosphere, which causes surface warming, which alters atmospheric circulation, which alters cloud cover, which impacts surface temperature.

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

They can not, first because they measure temperatures on only a small part of the Earth's surface, second because they are notoriously unreliable, and third because they tell us nothing about what is causing warming or cooling.

Since you are a frequent visitor to WUWT, you are well aware that I have illustrated, explained, and animated cause (ENSO) and effect (the warming of sea surface temperatures, ocean heat content, lower troposphere temperatures, and land + sea surface temperatures) in dozens of blog posts over the past 3 1/2 years.

The slowed surface warming is due in large part to changes in ocean cycles, particularly in the Pacific Ocean, causing more efficient ocean heat uptake, thus leaving less heat to warm surface temperatures.

As you can see, over periods of a few decades, modeled internal variability does not cause surface temperatures to change by more than 0.3 °C, and over longer periods, such as the entire 20th Century, its transient warming and cooling influences tend to average out, and internal variability does not cause long - term temperature trends.

A new study on ice loss in Antarctica by the British Antarctic Survey confirms what we already know about the effects of global warming but it differentiates between the effects of ocean currents, their cause and the air temperature effects at the ice surface.
