..I believe Global Warming is real. So is global cooling. And its been going on for quite a while....
There are wetland plants preserved in a Peruvian Ice Cap, that were basically flash frozen 5200 years ago. Of course the ice is retreating now, exposing the plants.
Lonnie Thompson and his research team have drilled ice cores from Quelccaya that date back almost 2,000 years and have used them to study changes in atmospheric conditions over this period. In these samples, the oxygen isotope ratio, oxygen-18 to oxygen-16, has risen abruptly in the last 50 years, an indicator of regional warming. As the ice cap is retreating, it is exposing almost perfectly preserved, unfossilized plant specimens that have been dated to 5,200 years before present, indicating that it has been more than 50 centuries since the ice cap was smaller than it is today.[3
