Learn about world’s ‘Frozen Assets’ May 12

YAKIMA – Mountaineer and climate scientist Steven Ghan hopes to give people a visual understanding of climate issues through a presentation focusing on the crest of the North Cascades, showing evidence of glacier retreat as well as spectacular alpine scenery.

Ghan’s presentation, “Frozen Assets,” will be held Tuesday, May 12, at 7 p.m. at Yakima Valley Community College’s Parker Room (1000 S. 12th Ave.) in Yakima.

The presentation will provide data on the retreat of glaciers, reductions in mountain snowpack, loss of Arctic sea ice and melting of Greenland ice. He’ll place these recent changes within the context of the repeated advance and retreat of ice over the last 800,000 years, and will provide a physically consistent explanation for them.

In the Yakima Valley, he notes, residents are facing water supply shortages that become increasingly frequent as the climate warms.

Ghan will discuss the likely outcome and profound human impacts of the continued depletion of the world’s frozen water, and will offer concrete and effective suggestions to prevent the global ice melt.
