Hi All,
Bryant made an extremely valid point when he commented that "not many people are up to running those things through their minds". I'm reading a very interesting book called, Enlightenment 2.0 by Joseph Heath which is looking at how the human brain works from the evolutionary point of view. We simply have not evolved to work co-cooperatively on a global scale regarding long term issues like Global Warming, so it takes
energy, discipline and effort to engage the reasoning side of our brains to do just that. It may take effort, but humans have surprised the "popular belief" big business gurus in the past, and
permie sort of people are just the outside the box type thinkers who will lead the way.
However, one of the other areas Mr. Heath discusses is how difficult it can be to see what the "real threat" is. We aren't naturally good at probability - and with any global statement like that, we need to consider that some are far better than others at such things. Thus, Governments seem happy to spend our tax money on "The Terrorist Threat", which is no where near the top 10 list of what is likely to kill us but is frightening and in the news, than on preventative medicine for cancer or heart disease.

The housing industry is being run by big business so it's up to the few strong, far seeing individuals who see how Global Warming will interact with our current building standards and push for changes and exemptions. There isn't one solution that fits all ecosystems - houses on stilts are more appropriate where flooding is the greatest threat, whereas I expect earth-bermed would keep you better protected from wildfire. I'm not sure humans have invented a house that is bullet-proof from every natural disaster, but the solutions raised in this thread are all better than the status quo. The basic
permaculture principles outlined in every design book on the subject show how slowing water movement, directing wind, breaking up straight lines with berms and different heights of vegetation, will help protect the land from "storms of the decade" and probably "storms of the century", but there will be a certain level of luck involved in protecting our homes from "storms of the new reality". Having back-up infrastructure and redundancy will make us more resilient, so over-engineering your garden shed and fully insulating it so if something happens to your house you still have a place to shelter from the storm has a certain appeal to me! Having several sheds designed with different threats in mind might be quite appropriate on a larger piece of land where the threats are very different. (We have times of the year where forest fires are a major threat but we also live in a known earthquake zone. )
If your circumstances are such that living in a city in housing that won't totally alienate your neighbors is where you are at, there are still things you can do that will help. Simple roof lines oriented to resist the likeliest peak wind, rather than the currently popular chopped up, eddy-creating monstrosities I see in every recent building development I've entered, will help protect your home from wildfire, extreme wind and extreme snowfall. I've known since the 70's that in areas prone to drought and wildfire, cedar shakes are a "bad idea" regardless of them being environmentally sound in the
permaculture way. I've heard mixed reviews about green roofs - I've read concerns that dry vegetation is a fire risk, but never whether the house underneath that roof actually burned! It seems to me that a bunch of dirt and rocks on my roof are less likely to burn my house down than some of the alternatives, and if anyone has more information on fire safety and green roofs, I'd love some links. Buying a house that isn't at the bottom of a denuded slope (mudslide risk) or on a flood plain or delta (duh!) might seem simple, but without knowing something about the geological long term history of a place, may not be as obvious as we enter extreme weather event territory as we think.
This is not a simple topic with easy solutions, but more a work in progress as we explore more human-friendly building practices and forms that aren't going to be seen in the popular press - at least not very often, and not yet "mainstream". Keep up the good work!
