I just watched a Nova documentary called Arctic Dinosaurs that included some scientific findings that cracked me up.
One of the scientists featured in the film is Robert Spicer, a British paleobotanist. (He studies fossilized plants.) He explained that, in hot tropical climates, the edges of leaves are smooth, while in colder climates, they tend to have serrated edges. In hot climates, moisture evaporates from leaves, causing water to rise up through the roots. In cold weather, evaporation ceases. To avoid starvation, plants in colder climates have little glands on the edges of the leaves that pump water out and keep critical circulation going. These glands make the leaf edges jagged.
Spicer got the bright idea that he might be able to use his plant fossils to figure out what the climate was like when dinosaurs roamed. First, he collected a ton of modern leaf and climate data from more than 170 locations around the world. From these, he was able to create a statistical model that accurately predicts, to within a degree or two Celsius, what the average annual temperature of a given place is (or was) by the proportion of toothed leaves and non-toothed leaves in the environment.
Neat, huh? By examining his extensive collection of ancient arctic leaf fossils, Spicer demonstrated that, when dinosaurs were living on the North Slope of Alaska, the average annual temperature there was about 30 degrees warmer than it is today. So I’m thinking, “Continental drift, people!” but the joke was on me. According to geologists, at the end of the age of dinosaurs, the North Slope of Alaska was not further south. It was further north!
Yet it was 30 degrees warmer and enjoyed a great diversity of plant, insect and animal species.
Think about it. The Gore-Bull Warmists shriek about the Catastrophic Consequences of even a small rise in average global temperature, right? But back when Alaska was 30 degrees warmer, it was much MORE hospitable to life than it is now.
