You're missing the point. Many places won't be able to grow food anymore, not in sufficient quantities.

It's irrelevant if Ukraine produces 20% extra if other countries can't make enough food. You can't always assume international trade is there or that poor countries, especially, can afford it.

Plants like more carbon and more heat. Areas that are currently too cold to grow will become capable with longer grow cycles. We can enrich soil with fertilizer to make it better.

In the past, current deserts (Iraq / Mesopotamia) were much more hospitable to plants and life. Now they are not. Climate change has been a fact of life for all of human history. Now it may be man made, but that doesn’t change the fact that we have lived through this before. The Bible is full of stories regarding drought, famine, floods. That is part of nature.

Those past changes were quite disruptive, causing malnutrition and death, wars, etc. The current rate of change is much faster so we should expect all of those to be worse because there are far more people alive now and neither humanity nor the ecosystem have much time to adapt.

I disagree - I think modern society, international trade, and communication systems make such disasters far, far less likely.
