“What we got here is a failure to communicate”
- Cool Hand Luke, 1967

What’s the message?
• The problem’s so big your actions don’t matter
• Be afraid / worried / depressed / angry
• You must change the way you live. Now.
or:
• There are many practical ways to address the problem, and these have multiple benefits.

The proposition
Climate change by itself is not an actionable issue
for most people.
It’s too overwhelming, scientifically complex and
politically charged to motivate behavior change.
People can be motivated to act on specific issues
that address climate change through a mixture of
examples, technical information and incentives.

Example of disconnect: Iowa farmers
Climate change primarily due to nature (23%)
Not enough evidence climate change exists (22%)
Climate change is not happening (3%)
Yet most of the farmers have concerns about:
Drought (92%)
Erosion (92%)
New insect pests (88%)
Extreme rain (83%) 2013 Iowa State Univ. poll, see: http://www.soc.iastate.edu/extension/ifrlp/PDF/PM3061.pdf

Attitudes towards climate change
Only 13% or people say they have taken any action to address climate change
![Page 9: Changing the climate change conversation · use manure management drainage, irrigation Climate Change tillage practices MITIGATION ADAPTATION . Public Health drug abuse diet diet](https://reader036.fdocuments.us/reader036/viewer/2022062607/6051daa673357c62b235a770/html5/thumbnails/9.jpg)
54% of Americans believe it is likely that extreme weather will cause a natural disaster in their community in the coming year. http://environment.yale.edu/climate-communication/article/extreme-weather-public-opinion-April-2013#sthash.w4XByyHu.dpuf
57% of Americans say the U.S. should emphasize conservation to solve the nation's energy problems. http://www.gallup.com/poll/168176/americans-favor-energy-conservation-production.aspx
30% of Americans say they would like to decrease the amount of meat they eat. http://truvenhealth.com/NPR-Truven-Health-Poll/Meat-Consumption-03-2012.pdf

Recommendations
Focus on what people can do, and how to do it – not on climate science, projections, or politics.
Describe multiple benefits of specific actions.
Establish targets for adoption.
Improve estimates of GHG impacts so that ‘best practices’ can be prioritized.

targets for consumers
• reduce food waste
• buy less processed food
• buy less packaged food
• lower energy used for food storage
• consume less meat
• fewer food miles – buy local?

Dietary choices affect GHG emissions

Food hubs may do the same – research is needed!

targets for farmers
• less fertilizer N use
• more (efficiently) irrigated acres
• more tile-drained acres
• increased use of IPM / monitoring
• more passive and renewable energy use
• better manure management
• fewer animals, more value-added

Research and outreach should help consumers, farmers and
food businesses understand and prioritize the many practical actions that can be taken to
address climate change.
