The desertification is predicted for hotter latitudes than ours. See maps.
The overwhelming majority of the world's population live in that big orange desert belt. Upon reading the accompanying notes on the first map I have to ask: where exactly did you source that? Because it looks like something from a science-fiction book, or at least some publication divorced from the realities of the banal factoids it presents.
For example, the passages on Asia and Southern China are but two (of the many!) that leap immediately out from that map... This covers the two most populous regions on earth comprising of over 2.7 billion people (and we're not even counting the additional half a billion from 'peripheral' populations such as Japan, Indonesia, The Phillipines, South-East Asia). Where do you think these people are going to go? What do you think is going to happen to them? THREE of the world's Major nuclear powers live in the directly affected areas (China, India, Pakistan) and these three nuclear powers also comprise the largest conventional land-based forces on the planet.
Do you think these countries are just going to roll over and 'depopulate'? If so, WHERE do you think they are going to go to?
What happens if the environmental stresses become so intense that there ends up being an actual shooting war between those three nuclear powers that ends up going nuclear? Where are the vast areas of uninhabitable irradiated wilderness on that fantasy-league map of yours? Because, lets face it, a significant chunk of central Asia being turned into a radioactive dust-bowl is just as likely as vast tracts of the world being given over to solar farms and geothermal energy with zero push-back from the local population of those zones...
What about the 'desert USA' in that map? Well... That's a whole other bowl of crazy that for brevity's sake is best to avoid right now...
Rises in sea level are not expected to be calamitous for much of the UK.
Bullshit. A significant proportion of our most productive arable land sits squarely in areas that will be inundated (or in some cases partially inundated) due to sea-level rises.
I doubt we have enough forest to make parts of the UK uninhabitable because of smoke particles in the air, as has happened already in parts of California.
Were you in the north of England when the moors were on fire? That was not a forest fire; ask anyone who was there what the air quality was like -the answer may astound you...
And only a trickle of refugees could get here by boat. We would cope, there wouldn't be societal collapse, nobody would die of hunger or thirst. That's what I mean by "fine".
...and this, THIS^ right here is why I say you're fucking deluded mate.
In the face of that catastrophe porn map you've provided, the only way that societal collapse could possibly be averted whilst reducing the flow of refugees to a trickle is by the adoption of some incredibly extreme measures -in which case there
would be societal collapse as those measures are the sorts of ones that our current society would never wear.
If we can't grow food for some reason, obviously we wouldn't be fine.
The
current available land area of the UK is insufficient to properly feed the existing population and that's leaving aside:
(a) The reduced amount of arable land post-warming.
(b) The increase in UK population -especially since you think we'll be 'fine'...
I don't know what would happen if insects and birds stop pollinating crops. I've read that, broadly speaking, vegetables and cereal crops don't need insects for pollination but fruits do. Maybe someone will develop self-pollinating varieties of fruit.
Where did you read that???
I don't know anything about these maps. Make of them what you will.
Map 1: Where did you get that from? Genuinely curious about that one
Map 2: Even the author states that "
the science, however, is far from certain on the benefits of carbon fertilisation". So that in itself is an admission that it's a thought experiment with no definitive proof of it being the case in practice.
...If this represents your vision of the future and how we, the UK, will be "fine" then I say again:
you are fucking deluded.
