(Orbital forcing doesn't have much
of a global annual average forcing, and it's even concievable that the sensitivity to orbital forcing as measured in terms of global averages and the long - term response (temporal scale of ice sheet response) might be approaching infinity or even be negative (if more sunlight is directed onto an ice sheet, the global average albedo might increase, but the ice sheet would be more likely to decay, with a global average albedo feedback that causes warming).
What's more, there are several long - term records

But even then the «fraction

average summer temperature, or the
average annual temperature?
... Polar amplification explains in part why Greenland Ice Sheet and the West Antarctic Ice Sheet appear to be highly sensitive to relatively small increases in CO2 concentration and
global mean temperature... Polar amplification occurs if the magnitude
of zonally
averaged surface temperature change at high latitudes exceeds the globally
averaged temperature change, in response to climate forcings and on time scales greater than the
annual cycle.

Thus, the simplest thing to do is to: a) construct a time series

Now I've seen mentions that (strong) El Nino years will make the
global annual average higher — e.g. 1998 was so warm partly because
of El Nino, and that this is due to the fact that sub-surface warmer water is brought up and allowed to affect the air temperature.
But more generally, something I've wondered is: while in the
global annual average, aerosols could be said to partly cancel (net effect) the warming from anthropogenic greenhouse forcing, the circulatory, latitudinal, regional, seasonal, diurnal, and internal variability changes would be some combination
of reduced changes from reduced AGW + some other changes related to aerosol forcing.

annual) and internal variability.
Re 37 Kevin McKinney — actually, orbitally - forced
global annual average changes in TOA solar insolation are very small (in the case
of Earth) and depend only on variations in eccentricity (setting aside the idea that there is a plane

Alignment
of perihelion near winter solstice would reduce the
annual average insolation (because that hemisphere'til ts away» from the sun during the time

This is an issue because we know there is a substantial long - term natural cooling trend for high - latitude summers because
