I am not a particularly religious person, but perhaps is this where the story "Noahs Ark" comes from? Sea levels, heavy rain, its starting to sound familiar now.
All governments feel the need to be "seen" to be doing something, perhaps extra taxes will help to relocate people, I just wish they would be more honest about it, we have many years before things get really bad, but people are moving away from their poor countries and already trying to resettle in the EU, where food is already short we are seeing mass immigration, people don't just sit there and starve like they used to, they know with better communication nowadays that there are places on earth where there is food, and like your cavemen Lutz, they are already moving. It makes our daily lives driving around in whatever vehicle we need pan into insignificance if you dare to look at the bigger picture.
If we bury our heads in the sand, then we know there are enough resources for our lifetime and hopefully our children. I have two new grandsons, and I do fear for them although I do believe there will be alternative resources. For example, we do not use the rising sea to our advantage, with desalination plants they could irrigate the dry desert areas to grow crops. We have not researched the use of wave and tidal power, the UK has the possibility of free power just by harnessing wave power but it doesn't choose to. The public are against nuclear power stations, they don't like tall ugly wind turbines, but wave power would be hidden under the sea.
Yes, we will all probably have to have electric cars in the future, but the batteries to run the cars are an ecological nightmare. Man will adjust to the changing earth, he has managed to so far, we have to work with it, and it would be very helpful if the population could be better controlled, perhaps it would be better if government didn't encourage large families to help ease the burden on earth, but the climate will carry on regardless of what we do, we just need to acknowledge that we must work with changes and try to use them to our advantage, we can't stop or alter the earth's natural thermostat, but it is very wrong that governments raise taxes in such a dishonest way, it sets man against man arguing about whose car is more environmentally friendly when in actual fact it just doesn't make the slightest difference - only to the owners pocket - the ice is going to melt anyway, whether we are here or not, any taxes raised should be used to start planning for new food production in areas where it is too dry etc, homes should be planned that possibly float! Anything would be better than governments just creaming off our money and using it to bailout banks etc!
