Food Sources: Disruption, Climate Change, and Oceans

Food Disruption, Climate Change, and Ocean Sources of Food: Part 1 of 3 // Published on Jan 18, 2017

I tell the story of how our global food supply, derived from land and ocean, is being severely stressed by climate change caused extreme weather events, ocean warming, acidification and stratification. Destructive farming practices, overfishing and poor aquaculture practices are also exacerbating the problem.


Abrupt climate change cannot be dismissed any longer.


We are in a global climate change emergency, and very soon it will severely stress large portions of our global food supply leading to global societal chaos.

Reference:  Climate Change Impacts on Food Security, from Peter Carter.


IPCC 5th Assessment 2014:  ‘Assessment and Future Food Security

‘The IPCC results are very important to understand because it is only the IPCC assessment that is recognized by policy makers and governments.

There are already observed changes top crop yields, which have all been negative for all regions.

The results for the future from computer model projections do not capture the extent of many large adverse impacts- including prolonged drought, heat waves, floods,pests ground level ozone and climate variability.’
