As global warming continues, what are the sources of hope for communities around the globe? On this UN Sunday, we’ll hear one of the newest generation of committed leaders on this global crisis. Along with startling facts, he will tell us what the scientific community is doing about this crisis–and steps that we can take to fight climate change.

Kareem Hammoud is a senior in Environmental Science at UCBerkeley and a Head Chair in the Berkeley “Model United Nations” program. A native of the Los Angeles area, he has been interested in climate change since being in a 10th grade speech contest. His involvement in Model UN programs through high school and college deepened his interest in human impacts on the world. In helping to lead the Berkeley Model UN, he designs and moderates the debates of 1,500 American and international high school delegates. He also serves on the UC Green Initiative Fund, which collects and grants money to sustainability projects. These include ecological restoration of Strawberry Creek, installation of reusable-water “hydration stations” and the storefront of the Berkeley Student Food Cooperative.
