Contrasting futures for ocean and society from different anthropogenic CO2 emissions scenarios
-
The ocean moderates anthropogenic climate change at the cost of profound alterations of its physics, chemistry, ecology, and services. Here, we evaluate and compare the risks of impacts on marine and coastal ecosystems—and the goods and services they provide—for growing cumulative carbon emissions under two contrasting emissions scenarios. The current emissions trajectory would rapidly and significantly alter many ecosystems and the associated services on which humans heavily depend. A reduced emissions scenario — consistent with the Copenhagen Accord’s goal of a global temperature increase of less than 2°C — is much more favorable to the ocean but still substantially alters important marine ecosystems and associated goods and services. The management options to address ocean impacts narrow as the ocean warms and acidifies.

Climate Change Impact: Food Systems, Food Security, and Global Linkages
-
Food systems both impact and are affected by climate change. Emissions come not only from farming, but also from the processing, manufacturing, distribution, storage, sale, and preparation of food, and the disposal of food wastes. Likewise, climate change influences not just agriculture, but activities that occur throughout this larger system. In this talk, Dr. Peters will address the fundamental concepts of food systems and food security. He will explain how scientists estimate climate emissions from individual supply chains and from whole food systems. He will also consider case study examples of strategies for reducing emissions viewed both from the production and consumer ends of the food system.

NIFA's Information Webinar on Climate Change Programs
-
Rapidly changing climate is one of the most pressing issues facing farmers, ranchers, landowners, households and communities. To address these climate change challenges, individuals, families and communities need the best available science to plan for and implement climate-smart and resilient practices.
n this webinar, National Program Leaders from each of the outlined programs gave a brief description of the program, proposal submission deadlines and other pertinent program information. This webinar is especially useful for project directors with climate based/climate emphasized research, Extension and education projects.
