Why does earth's orbit affect our climate?
Earth orbits Sun in an elliptical path.
But the change in distance from 147 million Km to 152 million KM does not make much change in temperature.
Axial ti;lt of Earth 23.4 degree is causing the real change in climate.
THis causes sun light to strike at different angles and this causes the temperature change.When Sun light strikes at 90 degree we get n maximum heat.
Earth is nearest to earth on January 4th and we have winter in northern hemisphere.
