The curved
shape of Earth affects the area of the surface covered by the same amount of sunlight.

That would happen regardless

Regional variations arise because the
Earth's gravity field is
affected in multiple ways by the melt
of ice, due to the direct effect
of surface mass changes (the gravity field is determined by the distribution
of mass), the consequent deformation
of the Solid
Earth (removing a load causes the
Earth's surface to rebound, which in turn changes the distribution
of the
Earth's mass), the consequent redistribution
of ocean water (the ocean surface is
shaped by the gravity filed) and perturbations
of the
Earth's rotation axis (because
of mass redistribution).
First, variations in the
shape of the
earth's orbit (more versus less elliptical), the axial tilt, and the direction
of that tilt with respect to perhelion all combine to
affect the relative seasonal insolation for the northern and southern hemispheres.
Refraction, specifically the real component
of refraction n (describes bending
of rays, wavelength changes relative to a vacuum,
affects blackbody fluxes and intensities — as opposed to the imaginary component, which is related to absorption and emission) is relatively unimportant to
shaping radiant fluxes through the atmosphere on
Earth (except on the small scale processes where it (along with difraction, reflection) gives rise to scattering, particularly
of solar radiation — in that case, the effect on the larger scale can be described by scattering properties, the emergent behavior).
7 Natural Processes that Change Climate
Earth Motions Geographic changes in
Earth's land and water bodies cause changes in climate Changes in the
shape of Earth's orbit and the tilt
of Earth's axis
affect global climates.
What happens on longer periods is largely unrelated and
affected strongly by the changing
shape of the
Earth due to tectonic movements, rebounding
of the mantle and crust and occasional earthquakes.
According to this theory, changes in the
shape of Earth's orbit around the sun (eccentricity), variations in
Earth's axial tilt (obliquity), and the tendency for
Earth to «wobble» with respect to the direction
of its rotational axis (precession)
affect climate.
These gravitational forces thus
affect the actual
shape of the trajectory spiral, and we all know: If the
Earth moves for 2 months on an orbit spiral section, somewhat further away from the Sun, this will result in less RF (radiative forcing) for 2 months received on
Earth.
Earth's motions Changes in the
shape of Earth's orbit, the tilt
of its axis, and the axis
of its rotation
affect the intensity
of the seasons.
And as an interesting article in EOS recently noted, humanity is
affecting the very
shape of Earth's surface in unprecedented ways.
