We would not have the seasons as we currently know them. There would be essentially no seasonal change anywhere over the course of the year. Any differences would be minor.

The year.
Approximately 23°. As a matter of interest, the Tropics of Cancer and capricorn are 23° from the Equator, these representing the most northerly/southerly points on the Earth where the Sun can be directly overhead. This is due to that tilt of the earth.

The Earth's axis is tiled 23.4 degrees. It tilts away from the perpendicular of its orbital plane which is why seasons are produced on Earth. The earth rotates on its axis 266.26 times each year.
Mercury
Earths orbital inclination is 1.57869°
The Earth's axis is tilted at about 23.5 degrees from the perpendicular to the orbital plane. Or to put it another way, the Earth's equator is tilted at 23.5 degrees to the Earth's orbital plane. The main effect is to cause the seasons. That's because the tilt affects the amount of sunlight a particular place gets as the Earth orbits the Sun.

The tilt of the earth's axis, away from the perpendicular to its orbital plane, has a much greater influence on the climate in any one place than the earth's distance from the sun has. As you correctly point out, the earth's orbital distance from the sun is completely overshadowed by other effects.
In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, or, equivalently, the angle between its equatorial plane and orbital plane. It differs from orbital inclination.
The Earths orbit is fairly un-eccentric when compared to the other planets, with only Neptune and Venus having more regular (less eccentric) orbits. The eccentricity of earths orbit is 0.0167, the closest to this is Neptune's, with a value of 0.00859

The Earths orbital distance from the sun is 147,098,290km (91,402,641 miles) at its closest (Perihelion).
