denialists are quick to describe the current Australian heat wave as a just a bit of sunshine. But the Australian wheat market is responding to the drought by hiking wheat prices through that thing that denialists seem to love so much- the law of supply and demand.
In reality, the world wheat market is under mild pressure. last year's wheat crop in the USA was sketchy because of our drought in the great plains. Russia, another major exporter, kept more wheat at home than usual due to weather trouble there. Now it is Australia's turn. If you are a wheat farmer, it is great news for you, because shortages mean that you will get good prices. if you are a poor person living anywhere on our planet, it is not so nice, because wheat is a global market, just like oil. In a global market, there is no place to hide from a commodity shortage, because places lacking the commodity suck it away from places that have it, through the magic of money.
We learn from this the lesson that food shortage and famine are a key consequence of global warming. It is not about humans being barbecued alive in 100 degree Fahrenheit temps. hey give us some water and some shade, that is not a big deal. But when crops die, there is no place to hide, because humans cannot eat sand.
The chief two dangers of global warming to humans are starvation and flooding from sea level rise due to the melting of ice sheets and glaciers. Water runs downhill, did you notice that? Sure, it will also cause widespread species extinctions, but bottom line, humans really only care about themselves. Sure, the heat will be uncomfortable, but that is not the heart of the danger.
