Two sides I have seen:
For: Dislocated proletariat is the moving force of history that renew the dying material world. The people are the ones who create history. The revolutionaries will come between the chaos and guide the dislocated people to a better path, each time a better world.
The dishearted and unawakened must know that history is about revolution, and we walk on the path of history without hesitation. A lot of people project the duality of the present state unto the future. As to make the future uncertain. Wrong, there is only one future. The end is the past, but the future is the beginning. Therefore a true communist should not be discouraged and fall into nihlism, because the future is determined. The only thing left for us to do is fight.
Against: The future is not determined yet. A materialist or anyone who claims to be a communist will not hold this idea. It results in waiting, waiting for the time, waiting for the proletarian “wake” and have “classes conscious”. This is a kantian leftist, not a hegelian leftist. We don’t believe that there is a decided, unchanged future “waiting ” for us. The only thing it lead to is the economy determinism like Ti1. For Lenin in 1917, there is no big other can say that the revolution will succeeded. Future determines past by the mediation of subjects’ practice.
For a while, the temperatures might be manageable with mass migration and air conditioning, but runaway warming will ensure that eventually we won't be able to grow food.
Plenty of our ancestors lived in worse places. We got enough people that the .5% china manages to save could eventually buld a nice city on the pole
Pole isn't farmable. New Zealand and Lake Baikal are our best bet once the Three Gorges water management system collapses between 2080 and 2100.
I don't think you understand what the greenhouse effect means. The more greenhouse gases released in the atmosphere, the more heat remains, and the more gases released into the atmosphere. It's a feedback loop. It has already begun with the Siberian methane thawing.
