Vostok ice core samples: p 465. Ice cores contain layers of ice harboring gas bubbles that reveal the composition of the ancient atmosphere.

Cryospheric Science: is the interdisciplinary study of permafrost, snow and ice, primarily on the surface of the Earth, but also on other planets and moons. Thecryosphere is an integral part of the climate system, and is investigated with techniques from geophysics, meteorology and hydrology.

Natural processes, phenomena to consider

Glaciation

We happen to be in an interglacial period–between ice ages. The earth’s orbit is complex, and slight variations in its tilt can cause temperatures in the Northern hemisphere to decrease.

The patterns are complex–there are three ‘cycles’ according to Milutin Milankovitch, a Serbian scientist who figured these out as a prisoner of war during WWI.

Milutin Milanković was a mathematician, astronomer, climatologist, geophysicist, civil engineer and popularizer of science. Milanković gave two fundamental contributions to global science.
