In recent years, a brand of research called «climate attribution science» has sprouted from this question, examining the impact of extreme events to determine how much — often in fractional terms — is related to human - induced climate change, and how much to natural variability (whether in climate patterns such as the El Niño / La Niña - Southern Oscillation, sea - surface temperatures, changes in incoming solar radiation, or a host of other possible factors).

However, the change in incoming solar radiation — insolation — at this timescale is small, and therefore difficult to reconcile with the amplitude of the glacial cycles.

I was mainly referring to the change in the distribution of the incoming solar energy, which from what I understand is rather large.

Although the primary driver of glacial — interglacial cycles lies in the seasonal and latitudinal distribution of incoming solar energy driven by changes in the geometry of the Earth's orbit around the Sun («orbital forcing»), reconstructions and simulations together show that the full magnitude of glacial — interglacial temperature and ice volume changes can not be explained without accounting for changes in atmospheric CO2 content and the associated climate feedbacks.

The paragraph in the OP you quote from as well as the one above it in full are saying that the ice age cycles result from the Earth's changing orbit round the sun which creates changes in the «incoming solar radiation (insolation) at high latitudes» (Roe (2006) PDF).

A change of that magnitude in the incoming solar radiation itself is not possible since satellite observations would have seen it.

[Response: They are imposed directly as cyclic changes in the amount (and spectra) of the incoming solar radiation.

The incoming solar radiation has changed just a tiny bit in comparison — since 1950, by the way, it has even decreased and thus offset a small part of the human - caused warming — hence humans have probably caused more warming than is observed (best estimate is 110 % of observed warming).

Residential solar energy, although growing by leaps and bounds, tends to only be within reach of people with a middle class or higher income, but a new initiative in California aims to try to change that, by offering home solar arrays with no up - front costs to lower income homeowners.

Save the average American family nearly $ 85 on their annual energy bill in 2030, reducing enough energy to power 30 million homes, and save consumers a total of $ 155 billion from 2020 - 2030; Give a head start to wind and solar deployment and prioritize the deployment of energy efficiency improvements in low - income communities that need it most early in the program through a Clean Energy Incentive Program; and Continue American leadership on climate change by keeping us on track to meet the economy - wide emissions targets we have set, including the goal of reducing emissions to 17 percent below 2005 levels by 2020 and to 26 - 28 percent below 2005 levels by 2025.»

radiative forcing a change in average net radiation at the top of the troposphere resulting from a change in either solar or infrared radiation due to a change in atmospheric greenhouse gases concentrations; perturbance in the balance between incoming solar radiation and outgoing infrared radiation

Note that the inversion at the tropopause is entirely a result of ozone reacting with incoming solar radiation and particles so any change in the ozone creation / destruction balance is going to affect the air circulation below the tropopause.

According to their modeling studies, the difference in the amount of incoming solar radiation, in this case, primarily in the ultraviolet (UV) wavelengths, during the minima and maxima of the 11 - yr solar cycle are large enough to produce a characteristic change in the winter circulation pattern of the atmosphere over North America... When the NAO is in its negative phase, more cold air can seep south from the Arctic and impact the lower latitudes of Europe and the eastern U.S., which helps spin up winter storm systems.

Dr Curry, When considering changes in albedo due to melting, pools, etc, is there also consideration that the Sun is very low in the sky and much of the incoming Solar is reflected off water as glare?

The authors found that consistent with previous research, changes in solar and volcanic activity, land cover, and incoming solar radiation due to the Earth's orbital cycles were the main contributors to the cooling between the MWP and LIA (the years 900 — 1600), and probably also caused the cooling over the full 2,000 - year period.

Measures to reduce the heating and cooling needs of the passengers, for example by changing window glass to reflect incoming solar radiation, are included in the group of measures.

These explanations may have to be revisited, but the correlations may still be valid, e.g., if it transpires that solar variability influences the formation of the heavy phase, or if the changes in incoming ultraviolet radiation are redistributed throughout the atmosphere, after absorption in the stratosphere.

A small localized change in surface temperature can cause a convection burst (thunderstorm) and a large increase in convection height, improving both reflection of incoming solar radiation, and conveying sensible heat to a higher altitude where it can then escape to space via radiative processes with far less interference.

UPDATED Sept. 5 I encourage anyone interested in climate change science and policy to explore the rich discussion below about geoengineering, in this case mainly focused on managing incoming solar radiation to counter CO2 - driven global warming — particularly in the context of the long (and building) commitment to warming already baked into the climate system.

Radiative forcing: A change in average net radiation at the top of the troposphere (known as the tropopause) because of a change in either incoming solar or exiting infrared radiation.

16 Natural Climate Changes Volcanic Activity Volcanic dust can remain suspended in the atmosphere for several years, reflecting incoming solar radiation and lower global temperatures.

Solar Radiation Management (SRM) or «albedo modification» is a class of technologies that could lower global average temperatures and offset some of the worst impacts of climate change by reflecting a portion of incoming solar radiation back into space before that radiation could be trapped by greenhouse gases in the atmospSolar Radiation Management (SRM) or «albedo modification» is a class of technologies that could lower global average temperatures and offset some of the worst impacts of climate change by reflecting a portion of incoming solar radiation back into space before that radiation could be trapped by greenhouse gases in the atmospsolar radiation back into space before that radiation could be trapped by greenhouse gases in the atmosphere.

Since it takes several hundred years for the deep ocean water to cycle up to the top, where it can be warmed up and lose CO2, it makes sense to suppose that if a warming event is initiated by something else (like changes in the amount and spatial distribution of incoming solar radiation,) the concomitant rise in atmospheric CO2 (which would enhance the initial warming) might lag behind by several hundred years.

Peter Huybers and George Denton went on to show that the glacial - interglacial climate near the North Pole varies with the intensity of incoming solar radiation at those latitudes, while variations in Antarctic climate seem to be governed by changes in the duration of summer (Huybers and Denton, 2008).

Some of them involved doing one thing or another to the oceans to change the way in which carbon is sequestered there, while others try to do things to the atmosphere to deflect incoming solar radiation.
