Howdy from Tucson, where the final day of Spring came in at (depending on which forecast you believe) somewhere between 112 and 114 degrees F (45 degrees C for you furriners). (Update: it was actually 115 F.)
It’s supposed to be even warmer tomorrow (make that in a few hours). (Update: It was warmer: 116 (47 C) ; in Phoenix it was 119. As I write, the high today was a mere 115, and we’re in for a major cooling spell this weekend, where the highs won’t get much above 110.)
About three weeks ago, after our first string of 100+ degree days, one of the local weathermen (Kevin Jeanes on KOLD — and sorry for the political incorrectness, that should be “weatherperson” or “person of weather”) with, shall we say a dry sense of humor, commented that the temperature was “all the way down to 99, and it’ll be even cooler tomorrow at 97.” (Again, for those of you who use a rational temperature scale, that translates to 37 C and 36 C.)
For those who haven’t been paying attention to U.S. climate models, they predict that this region, the desert Southwest, will be the hardest hit of the “lower 48.” And indeed it has been. We’ve been in a prolonged drought for nearly 20 years (broken last year by “normal” rainfall), and two of the last three years, 2014 and 2016, were the hottest on record. We just experienced the second warmest Spring ever, with the hottest March (high and mid 90s temperatures starting around March 1).
So, yeah, global warming is a “hoax.” We need to burn more coal. Donald Trump is an intelligent, honest, compassionate human being. And the unfettered greed inherent in capitalism isn’t a death sentence for the planet.
Things seem bleak, but we’re not totally screwed. There are things we can do individually and collectively to adapt and to counter global warming.
One thing damn near everyone can do is to plant trees. If done on a mass scale, this can reverse desertification. Even on an individual scale, it’s one of the best things we can do.
Gardening is another individual approach that makes sense. It involves far less expense than transporting food for thousands of miles, and involves far less waste. It also yields health benefits via relaxation, if nothing else.
Another individual approach, in arid regions, is to use xeriscaping, using native plants and a carpeting of rocks in place of lawns and non-native plants. This saves water — a lot of it, and it looks better than lawns.
Then there’s water harvesting — again, something damn near everyone (at least every property owner) can do at reasonable cost that will be amortized in a relatively few years. Even if you’re just channeling rain water from your roof and patio into wells for your fruit trees (as I am), it helps.
And then there’s passive solar heating (just think big picture windows facing south with an overhang that cuts off the sun in the summer months) and solar hot water heating (ultra easy — I built a solar hot water heater out of two old hot water heaters painted flat black [stripped of their external metal jacket and insulation], plumbing fittings, an old window, and scrap plywood and 2X4s about 20 years ago — a friend is still using it).
Then there’s ultra-insulation. Think straw bale and rammed earth construction. These energy-saving approaches can be used almost anywhere, and will often result in extremely energy-efficient dwellings.
To go even further on the individual scale, basements make a hell of a lot of sense in desert areas. Temperatures in them are a good 25 degrees F below surface temperatures, and there aren’t even seepage problems in deserts. The only reason they haven’t been adopted on a mass scale in the sprawlopalises of the Southwest is that land, historically, has been so damn cheap that builders have foregone them in place of slab construction, which yields better short-term profits. If you’re having a place built in this area, think about adding a basement.
As for societal approaches, they’re so obvious that I’ll mention them only in passing. First and foremost, a direct tax on carbon emissions — screw carbon “offsets”: they’re a recipe for fraud; massive public investment in clean energy; energy-efficient transport and appliances; mass investment in public transit, including bicycle projects; tree planting on a mass scale; and subsidies for individual clean energy projects, passive-solar retrofits, water harvesting, and energy-efficient construction.
Why do I think all of this is important? There are a couple of reasons.
One is that if adopted widely all of this would help save the planet (or at least make the lives of our children and their children better). The other is that it would keep people involved, and at least marginally hopeful. People without hope are easy to control and manipulate. Real, positive change is possible only when people have hope.
If you haven’t already done so — even on the smallest individual scale — please join those of us trying to create real change, please join those of us creating hope.
