I see people and nations trying to come to terms with global warming, but the efforts to reverse it seems disorganised, incomplete and ineffective. Governments sign agreements containing measures that sound good, but which are not implemented or implemented badly, and all the time the ice melts and the ice caps break apart.
I see Greta Thunberg ranting at the United Nations about their inaction on climate change. She has a point. If the world is to be saved, then those in power should take decisive action, now. But she is preaching to the wrong congregation. Most of those in the UN are in the later stages of their careers. The people that Greta should be taking to task are those of her parents’ generation, those who are just coming into their powers, mainly the millennials.
Can the millennials save the world? I think not.
Can the world be saved through democratic processes? I think not.
The problem with global warming is not the flooding of islands and the melting of the icecaps inundating coastal areas. People can always move inland. No, the problem is inland, in the areas that grow the crops that feed the world and in the forests that provide the life-giving oxygen and remove the stifling carbon dioxide. Global warming is going to inevitably cause crops to fail and forests to die. Droughts, floods, storms that devastate large parts of whole countries will become common.
This will lead to food shortages and famine. Famine leads to the spread of disease and to war, as those without food invade those areas which have food, and those who have food fight to keep what they have. Inevitably the wars will result in the inability of the food growing areas to produce food, leading to deepening famine, and deaths in the billions.
Technology will suffer. The things that we use every day, like cooking equipment, technology that we utilize to entertain ourselves, or our means of communication, like our smartphones, will not be produced as people find it necessary to concentrate on obtaining food rather than producing technological wonders. The networks will fail.
We will see the failure of democracy and the rise of autocracies as wars proliferate and famine and disease spread.
The autocracies and wholesale death by famine and disease may be the saving of the human race. If the human race is decimated, the pressure on the planet may ease, and the forests may return, springing up from remnants of the original forests or from species that have imported into the area by humans of our era. The autocrats may force workers to recreate the forests, because, after all, they will have experienced the effects of global warming. They can compel whereas democracies cannot. Autocrats are not magnanimous, but their best interests will hopefully be served by an end to global warming.
Where does that leave us? With a human population of much less than a billion. With the forests returning, maybe not the original forests, but forests made up of different species from other parts of the globe. There will be animals, but probably not the original species. With temperatures falling, and oceans returning to health.
There will be countries, but not the countries of today, and it is unlikely that any global organization, like the United Nations will remain. All current treaties and agreements will be long gone, replaced by other more local agreements and treaties.
Indigenous peoples may resurge in some places, but disappear in other.
It will be a world unlike our current world. Technology will have reverted as the huge factories needed to support it will have gone, but the knowledge may be retained, and the technology may resurge, but probably in a simpler fashion, using fewer resources. The day of the mega-factory will be over.
People will not fly around the world, and would probably live, and die close to where they were born. Large cities, of the size of London, Shanghi, or New York, will probably die, but smaller cities will likely survive.
That is the best case scenario. In the worst case the famines and wars will reduce the human race to very small numbers, and once the decline has got to those sorts of levels, the human race will fade away. No species resurges to previous levels after a die off of this magnitude without outside help. Where are the aliens when you need them ?
