Such changes are apparently sufficient to trigger major changes in climate — implying that the Earth's climate system may be more sensitive to
small solar radiative perturbations than one might think.

There are lots of experts on
small subsets of all the physics that go into climate,
radiative physics, clouds, aerosol, oceans, multi-decadal oscillations,
solar, global ice, etc..
To understand why
solar influence is so
small, it's helpful to compare the
radiative forcing from a cooling sun to the
radiative forcing from anthropogenic greenhouse gases.
«In comparison, changes in
solar irradiance since 1750 are estimated to have caused a
small radiative forcing of +0.12 [+0.06 to +0.30] W / m2, which is less than half the estimate given in the TAR.»
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.
Arking found that the «Effects of bias in
solar radiative transfer codes» to be «quite
small and in most cases negligible.»
I have also studied, for example, the effects of snow grain shape on the reflection of
solar radiation by snow, and the effects of subgrid - scale cloud features (clouds too
small to be resolved by a climate model) on
radiative transfer.
