Welcome to the weird world of weather radicalization. We're all watching it unfold right before our very eyes: extreme droughts, 500-year floods, fires and blizzards are all getting worse than anyone can remember. It's not just that we have more technology to detect and report on these storms today; the storms are actually getting worse and more frequent.
Simply put, when nature deviates from its normal cycles, it throws food production into chaos. A one-night drop below freezing, for example, can wipe out the entire citrus crop in Florida. A Midwest drought recently collapsed corn production there, and almost two years ago, a severe drought in Texas caused a collapse in grazing grasses, resulting in a mass slaughter of starving cows that could no longer be fed. The upshot of that was plummeting beef prices, followed by a spike the next year as herds had been thinned out far beyond normal.
The "latency" between the radical weather and resulting food prices is anywhere from one month (for fresh produce) to a full year (for processed, manufactured foods). This means that crazy weather patterns today might not spike food prices until next year, depending on the crops in question.
For food prices to drop, food production inputs must fall in price at the same time weather patterns become more predictable. This is extremely unlikely to occur any time in the foreseeable future, especially with fresh water, topsoil and fuel all becoming increasingly scarce and therefore more expensive.
Once you understand this relationship, you'll understand why rainfall and weather patterns are so crucial to the food supply. Just one inch of rainfall on just one acre of land delivers 6.2 million cubic inches of water to the land (and whatever is growing there). That's 27,000 gallons of water per acre with just a one-inch rain.
