> Famine is our future. In the USA, we are already locking up climate refugees, many children, in cages. Funnily enough, I think this would actually be justified if climate change was going to cause imminent famine as you're suggesting. Given the choice between having the population of the US undergo a mild famine while to the south there's a famine beyond living memory (thanks to preventing climate-motivated migration) or having a famine beyond living memory here (thanks to the extra few hundred million mouths to feed), I know which one I would want the US government to choose. Helping refugees is a good thing, but the US government has an obligation to US citizens first and foremost. That's why we call it the United States government, and not the Mexican government, or Guatemalan government, or Honduran... If you let too many people get into the lifeboat, you all drown. I don't think that this is currently the case, though. Famine, when it comes, will affect the rest of the world far more than it will the US, Canada, and Russia. Food will become more expensive, but that will be due to exports rather than having more people than the land can feed - unlike almost every other country on the planet. Also barring further improvements in agriculture, of course.
