I believe evolution is real, it is so slow that we don't see it. When a change occurs, and that is what evolution is, we panic and attribute the cause to the wrath of God or man made pollution. Our planet Earth rotates in an elliptical circle around our sun. This means there are moments in the cycle when the Earth is closer to the sun than other times. There also has been heavily polluted skies in prehistoric eras from spewing volcanoes. Our Earth changes constantly, we just choose not to see. Though scientists assure us that our Earth's orbit will remain stable for 100 million years, it is not perfect. Slight variances do occur.
I just found this interesting article on Antarctica:
"...warming in West Antarctica 20,000 years ago is not explained by a change in the
sun’s intensity. Instead, how the sun’s energy was distributed over the region
was a much bigger factor. It not only warmed the ice sheet but also warmed the
Southern Ocean that surrounds Antarctica, particularly during summer months when
more sea ice melting could take place."
This is written as pro-global warming, you decide.
