First, I’m into adaptation - not carbon or emissions nuttery. I help governments reduce risks by changing environmental and development policies. Adaptation is the process of reducing impacts from climate change. It’s basically preventing natural disasters using climate science. Read a short summary here.
That said, the movie is clearly misleading and propagandist (thus the title). It’s not difficult to find the correct sources of information on sources of emissions, primarily of which is the IPCC’s Fifth climate assessment report on mitigation: Climate Change 2014: Mitigation of Climate Change.
I generally avoid food posts, but am interested in the infrastructure that supports food systems.
One part of my current contract with USAID is a resilient wheat project in Kazakhstan. Kazakhstan is the 6th largest wheat producer in the world and mostly exports to east and central Europe, the Caucuses, and Asia.
Farmers there are facing three main issues: extreme temperature swings, which are increasing in frequency and causing terrible economic havocs; when to plant their crop, a problem because the planting timing and growing seasons are shifting; and shortage of storage silos for the wheat, especially in bumper seasons.
This last part - where to store the wheat - is probably the biggest issue developing countries (DCs) face with respect to dealing with climate impacted growing seasons. The farmers in Kazakhstan don’t trust the government, nor their seasonal forecastings. Nor do they (generally) reliably purchase crop insurance. So, the farmers tend to plant “when my neighbor plants,” put their finger to the wind, and hope for a good season. It’s very risky, and very unstable. They lose when there is a bad year, due to bad timing of planting, storms, droughts, etc.
But, and back to your question-ish, some years produce so much wheat that the farmers actually lose money. The reason is two fold. First, they lose on market price. The market price goes down when there is an abundance of wheat, it goes up when there is a shortage. The other problem with high-volumes is that there’s no storage system or infrastructure to support a storage system. Thus, all the silos get filled very quickly when all farmers produce record crops - when the silos are filled, the wheat is literally thrown away.
Tl;dnr, “the food crisis” is typically not due to a bad weather year, but due to inefficiencies in distribution. There’s plenty of food grown in the world. Climate change will affect the patterns of growth, but not to such an extent that the systems cannot adapt and adjust.
Getting crops from farm to table is the real issue…
