Expert addresses human impact on landscape

Oct. 15, 2015--International expert James (Jai) Syvitski will address the cumulative impact of humans on the landscape at the John R. Mather Visiting Scholars Lecture Thursday, Oct. 22, at 6 p.m. in the Gore Recital Hall at the Roselle Center for the Arts on the University of Delaware campus in Newark.

The lecture is free and open to the public, but registration is required by Oct. 15.

Syvitski is executive director of Community Surface Dynamics Modeling System (CSDMS) at the University of Colorado, Boulder. CSDMS is an international effort in 68 countries to develop, support and disseminate integrated computer models to the broader geoscience community to simulate the evolution of landscapes over different time intervals.

As chair of the International Geosphere-Biosphere Programme, he also provides essential scientific leadership and knowledge of the Earth system to help guide society toward sustainable pathways during rapid global change.

In his lecture, Syvitski will explore the striking extent to which humans are changing the Earth’s biophysical system — the atmosphere, ocean and land surface — and what it means, not just for humanity, but for science and policy, too.
