Join us in welcoming Henry Pollack as he leads a discussion on Ice, Water, and Climate!
Ice and water – the solid and liquid forms of H2O – can be thought of as partners on a global hydrological see-saw, the ups and downs of which are modulated by planetary-scale climate change. When the planet cools, some water solidifies to ice, and when the planet warms, some ice reverts to water.
Throughout the 20th and 21st centuries, Earth has generally been warming, and ice has been melting at an accelerating pace. The distribution of ice and water plays an important role in setting the temperature of Earth’s atmosphere, governing major weather patterns, regulating sea level and dramatically impacting agriculture, transportation, commerce and geopolitics.

Henry N. Pollack, Ph.D., has been a Professor of Geophysics at the University of Michigan for more than 40 years.
Among his numerous publications is Uncertain Science…Uncertain World, published by Cambridge University Press in 2003.In the scientific community, he has earned a reputation as one of the world’s leading experts on the temperature of the Earth, both today and in the geological past.
An award-winning teacher with a gift for explaining science to non-scientists, Pollack has taken a special interest in helping leaders in government, business, and the general public understand the scientific developments associated with global climate change. His specialties involve geophysics, global change, paleoclimate, geodynamics, and tectonophysics.
