Sort of, but not really.
The Earth's orbit around the sun is variable.
The solar system's position in space vis a vis the galactic plane is variable.
The solar system's position in the galaxy relative to the spiral arms of the galaxy is variable.
The main factors may be the solar magnetic field strength (directly related to sunspots) and the cosmic ray count in the part of the galaxy we are tranversing. The Earth's orbit around the sun may have little effect on climate change compared to how many cosmic rays make it through the solar magnetic shielding.
Here’s something to add to the discussion.
The Earth is actually farther away from the sun during the summer, and closer in the winter.
The ‘thing’ that makes the difference in our ‘weather’ is the tilt of the Earth, which varies the amount of atmosphere the sun’s rays have to penetrate.
