I know Lindzen has a theory that a change in tropical cloud cover will offset greenhouse - gas - caused warming, the unproven «iris effect».

I would suggest comparing peak to peak average temperature captures during weighted El - Nino events (during the time they occur, if they can be compared equally this would be a telling graph), instead of considering year to year records as a means of reducing ENSO effects on the temperature record, ENSO being largely a heat exchange between air and sea causing great changes in cloud distribution world wide.

Now, it turns out that the mix of forces that caused these colorful residents of cloud forests to vanish from misty slopes remains contentious even though they have become an icon in discussions of extinction dangers from rapid climate change.

But a change of -1.7 % in (high level) clouds over 1 decade caused a change of 1.2 W / m2 in reflected SW and ~ 3 W / m2 more IR radiation to space over the 30N / S band.

This would cause a change of 4.75 degrees K for the 100 % reference change in GCR over the 11 year solar cycle (and a non physical decrease of more than 100 % in cloud cover — are negative high clouds cooling and negative low clouds warming?

The 1.2 GU decrease in GCR (presumably) causes a 1.9 CU decrease in clouds; according to their figure 5A, a 5 CU change in clouds (~ +1 to -4) results in a 0.15 degree K change in temperature.

If the loss of heat by the oceans is caused by a change in radiation balance, the primary source of the change should be a change in (mainly tropical) cloud cover.

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.

It's looking more and more like most climate change can be pegged to changes in solar output, either directly through additional warming or indirectly as decreases in solar output allow more cosmic rays to reach the atmosphere, causing increased cloud nucleation and therefore increasing the earth's albedo and reflecting more solar radiation.

And how much of the hiatus is cloud caused in step changes in ocean and atmospheric circulation.

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.

WASHINGTON — A study on how much heat in Earth's atmosphere is caused by cloud cover has heated up the climate change blogosphere even as it is dismissed by many scientists.

In contrast, the IPCC's position is that clouds can only change in response to temperature change (temperature cause cloudsIn contrast, the IPCC's position is that clouds can only change in response to temperature change (temperature cause cloudsin response to temperature change (temperature cause clouds).

But neglecting causation in the opposite direction (clouds cause temperature) can lead to large errors in our understanding of how and why the climate system changes, as well as in our diagnosis of how sensitive the climate system is to human influences.»

Dr. Roy Spencer has proposed a hypothesis whereby some unknown internal mechanism causes cloud cover to change, which in turn changes the reflectivity (albedo) of the planet, thus causing warming or cooling.

In short, Dessler argues that cloud cover change is a feedback to a radiative forcing, for example increasing greenhouse gases, while Spencer argues that clouds are changing due to some other, unknown cause, and acting as a forcing themselves.

The mainstream and long - held view of clouds in relation to climate change is that clouds are acting as a feedback in response to temperature changes caused by human activity.

You have not cited a third possibility (out of the infinite range of possibilities), no climate change associated with CO2 (due to, for example, cloud cover providing negative feedback), with current increase due to natural variability; or how about possibility four, that increase in CO2 concentrations are caused by the temperature rise, which is in turn caused by (for example) increased solar activity resulting in increased biomass activity etc. etc..

The largest uncertainty in the future radiative forcing caused by sea - ice loss is related to how clouds in the Arctic will change.

This effect causes a total swing of about three percent change in cloud cover.

It was an appropriate hypothesis that rests in a knowledge gap (freely admitted by climate scientists - again in the IPCC), but Spencer seemed unable to pinpoint how long - term cloud changes can be decoupled from temperature changes (he hypothesised that ocean / atmospheric processes, like ENSO and PDO, can cause long - term changes in cloud dynamics - but didn't show how that happens).

«The overall slow decrease of upwelling SW flux from the mid-1980's until the end of the 1990's and subsequent increase from 2000 onwards appear to caused, primarily, by changes in global cloud cover (although there is a small increase of cloud optical thickness after 2000) and is confirmed by the ERBS measurements.»
