The Climate Change: An Accelerating Transformation: The Fourth Annual Earth Day Climate Change Symposium will consider the transformative impacts of climate change and efforts to respond to it. The program will begin with a panel that discusses aggressive efforts to respond to climate change by New York State and New York City and their global leadership in this regard. Speakers will discuss onshore and offshore renewable energy siting and development; groundbreaking State legislation and environmental justice; and NYC’s transition to transportation based on renewable energy. Our second panel will address the effects of climate change and efforts to respond to it at the federal and global levels. We will hear from a scientist at the National Oceanic and Atmospheric Administration regarding the state of the climate. We will also hear from other speakers about recent groundbreaking federal and other legislation; a landmark draft treaty at the United Nations to protect biodiversity in the oceans; corporate efforts to address climate change; and issues related to the supply of critical minerals for renewable energy infrastructure.
