Can you inherit zero? Where I live, there is a mandatory minimum inheritance for children - I think it’s 1/6 of the total? Cutting off financial help might result in them feeling stuck with their past choices, resulting in depression etc - I wouldn’t do that. Many successful entrepreneurs come from supportive households.

I've never heard of a law like that. Where I live, a person has full discretion on who inherits their estate if they explicitly write their will. Your offspring and next of kin are the default inheritors, but can be excluded if you explicitly say so in your will.

So I wasn’t right about the fixed part, it very much depends on whether there is a spouse to inherit it to.

Thanks for this! Lots of my peers are going on and on about how we're all doomed. I belisve in climate change, and that it's bad and we must act. But I don't think we're gonna be living in Waterworld, which is what my friends are describing.

There is a pretty major flaw in this write up, which is the assumption that the changes we may see will be linear, be it sea level rise, temps, etc. There are at least 4 tipping points that could upend this. If the Gulf Stream fails, Europe will be much colder than it is now, for example. Rapid breakdown of ice shelfs could quickly raise sea levels. “It won’t be bad because it has not yet” is thin.

Can you point me in the direction of some stuff that supports the likelihood of these scenarios? The middle latitudes being unlivable does seem extreme and unlikely to me, especially given the explanation in the article about how 85F was used as a threshold for unlivable by some studies.

What happens after 20 years?

Obama will be 80 in 20 years. Maybe OP means he will be close to death so he won’t care about climate change affecting his vacation home.

ya, I'm saying that even if climate change does destroy his beach house in 20 years, they will have gotten 20 years of use out of it.

Just interested in what temperatures have risen to that you need an AC? I also understand that buildings in normally colder climates are optimised to keep warm so that if things get hotter in general they are not going to cope well so an AC may well be necessary at temperatures that in other regions would be considered relatively cool.

It can get above 30C here[1][2], which is pretty hot for us. As you say, buildings are well insulated for the winter which means that the walls retains a lot of heat into the night once they've been baking for several days. Keep in mind the sun goes down at around 11pm, so it doesn't really get cold outside until well past midnight. In my home, that means it can be 25C inside for hours after bedtime unless I use AC a…

Is a good point and much what I thought was going on.

So your choices are, put up with it, with potential health problems for older/infirm people, rebuild to suit the new normal, or add an AC which hopefully is running from renewables and not contributing to the problem.

There is no easy solution.

I'm in Brisbane, and our climate is starting to move from northern subtropical to tropical. Most of the older houses are built for heat, but they are not built to deal with cyclones and extreme summer storms. Most of the new houses are not even built for heat, being designs that are popular in Sydney and Melbourne. Actually considering Sydney and Melbourne can get some stinking hot summers they are not even really built for that. Upshot is that most new houses are unliveable without AC, and this is in a country that has always had extremes of heat.

The threshold is typically 106F "wet bulb", above which much exposure will kill people, literally begin to cook them. Many parts of the world are hitting this.
