How does obliquity affect the climate?

Answer 1

Its effect on climate is measurable as incremental, for one half year, and decremental, for the other half.

At a place of latitude #theta^o# N/S, the angle of incidence of solar
rays has the annual range #theta +- ( obliquity ) 23.4^o#

In northern latitudes, if the range shift is gradual, it is

lower in southern latitudes and higher in the other direction.

When the angle is at a solstice, which occurs around December 21 or June 23,

either the maximum #theta + 23.4^o# or the minimum # theta-23.4^o #..
The mean value #latitude# is attained at an equinox ( by about

either September 23 or March 21)..

This variation in daily radiation has an impact on the local climate.

The absolute value for this rate of change ( #+-# ) is
#(4 X 23.4)/365.25#

= almost a quarter of a degree per day.

Answer 2

Obliquity, or the tilt of Earth's axis, affects climate by influencing the distribution of sunlight on the planet's surface throughout the year. When the tilt angle is greater, seasons become more extreme, with hotter summers and colder winters. Conversely, when the tilt angle is smaller, seasons become milder. This variation in sunlight distribution impacts temperature gradients, atmospheric circulation patterns, and the extent of polar ice caps, ultimately shaping global climate patterns over long timescales.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
