What sort of a climate change caused all of this ice to be formed in the polar regions? How does this relate to the current global warming hoax being foisted on us by the environmentalists?
I don't know. It's a legitimate point to ask and I don't fault you for it. I just didn't want anyone else to think that this was a U.S. study. Many nations include research as part of their national science efforts, so this comes out of the British science budget.

Good question. Looking WAY back, one of the causes that has been examined for the basic cooling of the Earth since the Eocene (the second period of the Cenozoic) was the formation of the Himalayas.
From Global Climate Change Student Guide: Internal Forcing Mechanisms: Orogeny
"Ruddiman & Kutzbach (1991) have proposed that the uplift of the Tibetan Plateau, the Himalayas and the Sierra Nevada in the American south-west may have induced a global cooling during the last 40 million years (see section 5.2.2.3). Raymo & Ruddiman (1992) also suggest that increased uplift of these regions exposed more rock, thereby increasing the rate of physical and chemical weathering. During chemical weathering, carbon dioxide is extracted from the atmosphere to react with the decomposing rock minerals to form bicarbonates. These bicarbonates are soluble and can be transported via rivers and other fluvial channels, finally to be deposited on ocean floors as sediment. In essence, carbon dioxide is sequestered from the atmosphere, thereby decreasing the Earth's natural greenhouse effect, causing further cooling."
