When I was a boy, Public schools used to frighten us with the hell of nuclear war. [We must all forget religious differences and get along.] Then it was "Silent Spring," when all the birdies and rabbits will die [We must get rid of every pollutant, real or imagined]. Then is was Global Freezing. [I forget what the atonement was for that hell.] Now it is Warming which has provided a windfall for bogus companies to find a solution by means of spending huge amounts of bogus money doled out to them to perform bogus science by venal politicians. No matter how big the failure, the people get to keep the money. Every decade or two another hell is invented so that saviors can offer their services. You must put your money in the pot so that your children will escape the current hell.
I do not believe in any collective hell with collective solutions. I believe in a very personal hell, operated by a personal God, which can be escaped only by personal faith in the person and work of Jesus Christ. All pseudo saviors will go to this personal hell and commune there together, unless they repent and personally make their peace with their Creator. I am not happy about it, but it isn't a hell I made up. Jesus mourned over Jerusalem because He knew about the real hell that isn't man-made. [Matt. 23:33-39; Luke 19:42] Man made hells cannot consume the people of God [Daniel 3:26]
