Climate Change 'Will Inflict Substantial Damages on US Lives'

Nov 26, 2018

Climate change is already harming Americans’ lives with “substantial damages” set to occur as global temperatures threaten to surge beyond internationally agreed limits, a major US government report has warned.

The influence of climate change is being felt across the US with increases in disastrous wildfires in the west, flooding on the east coast, soil loss in the midwest and coastal erosion in Alaska, according to the US National Climate Assessment. The Guardian saw a draft of the report before publication on Friday.

The draft outlined that “impacts of climate change are intensifying across the country, and that climate-related threats to Americans’ physical, social, and economic wellbeing are rising”. Climate change-related risks “will continue to grow without additional action”, it added.

Video: Dr. Emerson Nafziger: Nitrogen Fertilizer Rates for Corn

The Crop Science Podcast Show, Dr. Emerson Nafziger from the University of Illinois breaks down decades of nitrogen research. From the evolution of N rate guidelines to how soil health and hybrid genetics influence nitrogen use efficiency, this conversation unpacks the science behind smarter fertilization. Improving how we set nitrogen fertilizer rates for rainfed corn is a key focus. Discover why the MRTN model matters more than ever, and how shifting mindsets and better data can boost yields and environmental outcomes. Tune in now on all major platforms!

"The nitrogen that comes from soil mineralization is the first nitrogen the plant sees, and its role is underestimated."

Meet the guest:

Dr. Emerson Nafziger is Professor Emeritus of Crop Sciences at the University of Illinois at Urbana-Champaign, with degrees in agronomy from Ohio State, Purdue, and Illinois. His research has focused on nitrogen rate strategies and crop productivity. He co-developed the Maximum Return to Nitrogen (MRTN) model, which is widely used across the Midwest. His research spans N response trials, hybrid interactions, crop rotation effects, and yield stability.
