Agreed.

But there's a very weird underlying sentiment on HN where many people seem to directly or indirectly jump whenever they can to downplay the existence of climate change. Sometimes, they are emboldened by articles like this which intentionally use misleading headlines.

You're completely right, though, that in this instance, soy beans were mostly focused on because of consumer trends and less fertilizer need. Wheat is just an expensive crop right now. Also, soybeans would actually be less resilient to drought which furthers your point re: the article headline.
