I am establishing a citizen science network for observing changes in native plant phenology, the timing of plant growth, in response to climate change. I am training individuals joining this network to contribute observations of the sensitivity of plant flowering and growth to temperature conditions. With citizen participation, this project is creating a large-scale database necessary to document the impacts of global warming across central New York.||I am coordinating a faculty committee that is helping to develop the plan for Cornell to reach zero net greenhouse gas emissions. I am actively engaged in promoting activities on campus that will help define this plan. I have organized a series of classes focusing on evaluating costs and benefits of different strategies Cornell could pursue to reach climate neutrality. I am an active member of the President`s Climate Commitment Implementation Committee.
