Question

scientists cite evidence that earths climate has been changing significantly over the past 50 years. They also argue that changes to earth’s orbital path are not the cause of these significant changes to climate?

Answer 1

c. Changes to Earth's orbital path occur in a cycle that repeats every 100,000 years.

Explanation:

If changes to Earth's orbital path occur in a cycle that repeats every 100,000 years, then it wouldn't make sense that Earth's climate has been changing over the past 50 years. This cycle repeats and is over a very long period of time, so the climate wouldn't be changing significantly.

Not sure if my explanation helps, if it's any more assurance, I just got that question on a test and got it wrong, the answer was "c."

Answer 2

Answer: C.Changes to Earth's orbital path occur in a cycle that repeats every 100,000 years.
