Paleoclimatologist to discuss his work at La Jolla’s Birch Aquarium

Drilling down thousands of feet into the ancient ice preserved on Earth’s massive continental ice sheets allows scientists to extract a wealth of information about climate history — including periods both much colder and considerably warmer than today.

Paleoclimatologist Jeff Severinghaus will describe the work being done in this field, 7-8 p.m. Monday, April 14 as part of the Jeffrey B. Graham Perspectives on Ocean Science Lecture Series at Birch Aquarium at Scripps, 2300 Expedition Way, La Jolla.

Tickets are $8 ($5 students/teachers) and includes aquarium admission and parking. Light refreshments will be served. (858) 534-5771.
