Scientists cite evidence that Earth's 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 the climate. Which statement provides the strongest evidence in support of the scientists' argument? a
Variations in Earth's orbital path are consistent with accepted laws of planetary motion.
b
Earth's orbital path does not affect the amount of solar energy that Earth receives.
c
Changes to Earth's orbital path occur in a cycle that repeats every 100,000 years.
d
Climate change cannot be demonstrated over a span of 50 years.
