How would seasons vary if Earths eccentricity was 0.1?

Like would seasons disappear?

    No. They would be more extreme in one hemisphere and less extreme in the other.

    The seasons are more the result of our axial tilt, not the orbital eccentricity.

    Seasons would be more extreme

    The Worry would be about Climate and we might even Starve

      Seasons would be more extreme in the hemisphere where the axial tilt matched the difference in the orbit. Currently, that's the southern hemisphere.

      Seasons would be LESS extreme where the opposite is true. Currently that's the northern hemisphere.

    Earth's seasons are the result of the tilt of its axis, not the eccentricity of its orbit. The seasons would not disappear if the eccentricity changed.

    Also, as the current eccentricity is 0.0167, the increase you are talking about would amplify the differences in seasonal variation between the northern and southern hemispheres.

    At present, the Earth is closest to the Sun during the northern hemisphere's winter and farther away during its summer, which moderates the variations. The reverse is therefore the case in the southern hemisphere, amplifying the variations.

    Leaving the direction of the eccentricity the same, but increasing its magnitude, would increase that effect.
