Coincidence of dust volumes with massive cooling
In contrast, the dust volume that was laid down in Antarctica during the Ice Ages, was so great that it did have a dramatic cooling effect. The plotting of the dust volume shows clearly, that in every case the large dust volumes coincide with colder times of the Ice Age climate.
This coincidence of the large dust volumes with massive cooling, tells us that we are looking at very large dust volumes indeed, which are evidently globally extended throughout the atmosphere to have the measured climatic consequences.
The comparison raises two very big questions:
#1 Where did the enormous volume of dust come from?
#2 Why did the dust show up only half-way through the glacial periods?
If the dust had come from the world's deserts, it wouldn't have taken the dust tens of thousands of years to show up in Antarctica.
