I hope you're somewhere safe and warm and haven't been more than mildly inconvenienced by our current weather. If you've been wondering, as I have, how we can be "blessed" with these temperatures at the same time we're supposed to be experiencing global warming / climate change, take a look at the world-wide temperature patterns. It turns out that the IPCC anticipated this type of question back in their 2007 report. Dot Earth (See Other Paths to Follow sidebar, on the right) has done their usual great job of coverage on climate change.

I don't know how comfortable it is in your house, but, around here when it gets this cold, to borrow a phrase from It's a Wonderful Life "I don't know why we all don't have pneumonia. Draughty old barn! Its like living in a refrigerator." The difference starts to show up as the temperature drops below about twenty degrees. This morning's low of 24 below became really noticeable inside. (At least we're better protected than the local birds.) This has started me wondering how increasingly volatile weather (cold spells, storms, heat waves) will affect the design basis for our buildings and infrastructure. I seem to recall something about highways not being designed to accommodate peak hour traffic and storm water systems using a 25 year design storm. The concept, as I think I understand it, is that it would not be cost effective to design for peak flows. How this may change if and when we experience greater volatility in heat waves, cold spells, rainfall and whatever is unclear. Contrast this with how much it cost to rebuild NOLA after Katrina and how much it is costing to rebuild after "Sandy" walloped the East Coast.

It seems to me that we might be wise to try to save money, what's left of the climate as we currently know it, and our existing built environment by mitigating our Green House Gas emissions rather than rely only on a response based on adaptation. I haven't been tracking this topic very carefully but it seems to me this is one of former Secretary Rumsfeld's "known unknowns," things we know we don't know. For buildings, based on the obvious effects in my house caused by a lack of air sealing and insufficient attention the amount and quality of insulation on both comfort and economics, the question this homeowner is facing is "How often does this have to happen to make it worthwhile to fix it?" Looking at Duluth's recent storm water problems, similar questions are probably being discussed by the designers of Duluth's replacement system(s). Do we need a widespread conversation about prevention, adaptation and resilience for Minnesota's built environment. Should we just sit around and see what happens because of political and social concerns about appropriate responses? What do you think? Grace Paley makes it clear this is not a new topic for consideration.
House: Some Instructions
If you have a houseyou must think about it all the timeas you reside in the house soit must be a home in your mind
you must ask yourself (wherever you are)have I closed the front door
and the back door is often forgottennot against thieves necessarily
but the wind oh if it blowseither door open then the heat
the heat you’ve carefully nurturedwith layers of dry hardwood
and a couple of opposing greenbrought in to slow the fire
as well as the little pilot lightin the convenient gas backup
all of that care will be mocked becauseyou have not kept the house on your mind
but these may actually be amongthe smallest concerns for instance
the house could be settling you maynotice the thin slanting line of light
above the doors you have to think about thatluckily you have been paying attention
the house’s dryness can be humidifiedwith vaporizers in each room and pots
of water on the woodstove should you leavefor the movies after dinner ask yourself
have I turned down the thermometerand moved all wood paper away from the stove
the fiery result of excited distractioncould be too horrible to describe
now we should talk especially to Northernersof the freezing of the pipe this can often
be prevented by pumping water continuouslythrough the baseboard heating system
allowing the faucet to drip drip continuouslyday and night you must think about the drains
separately in fact you should have establishedtheir essential contribution to the ordinary
kitchen and toilet life of the housedigging these drains deep into warm earth
if it hasn’t snowed by mid-December youmust cover them with hay sometimes rugs
and blankets have been used do not betroubled by their monetary value
as this is a regionally appreciated emergencyyou may tell your friends to consider
your house as their own that isif they do not wear outdoor shoes
when thumping across the gleam of their poly-urethaned floors they must bring socks or slippers
to your house as well you must thinkof your house when you’re in it and
when you’re visiting the superior cabinetsand closets of others when you approach
your house in the late afternoonin any weather green or white you will catch
sight first of its new aluminum snow-resistantroof and the reflections in the cracked windows
its need in the last twenty-five years for paintwhich has created a lovely design
in russet pink and brown the colors of un-intentioned neglect you must admire the way it does not
(because of someone’s excellent decisionsixty years ago) stand on the high ridge deforming
the green profile of the hill but rests in the modestyof late middle age under the brow of the hill with
its back to the dark hemlock forest looking steadilyout for miles toward the cloud refiguring meadows and
mountains of the next state coming up the roadby foot or auto the house can be addressed personally
House! in the excitement of work and travel toother people’s houses with their interesting improvements
we thought of you often and spoke of your cozinessin winter your courage in wind and fire your small
airy rooms in humid summer how you nestle in springinto the leaves and flowers of the hawthorn and the sage green
leaves of the Russian olive tree House! you were not forgotten
