I don't think changing how elliptical the orbit is would cause ice ages as we know them. The average temperature should be about the same.
And that is why ice ages occur. Average temperature should be but it isn't.
Since scientists do not know when the Moon started orbiting the Earth, could the Moon influence ice ages?
Kind of why NASA's graph goes back about 800,000 years.
Now, can you tell us what colour you think a sunset is?
Put simply, in an elliptical orbit the planet spends longer at apogee then at perigee, so it cools down compared with its temperature in a circular orbit with the same mean kinetic energy.
