Out back is where the dingoes dance

Dancing Dingoes

No worries mates, the dingoes are dancing’, grab a Fosters and throw some veggies on the ‘barbie. I can’t say why the dingoes are dancing. Just go with it and enjoy the didgeridoo

I’m nearly normal again, well normal for me. Which is good. Tomorrow should be ok … fingers crossed.

So what did our ancestors do when it got hot during the summer? I’m sure it got hot and the humidity existed. I’ll say the words now as a precursor that this is not about the larger issue of global warming but it is as well. I’m not running my household AC, on purpose. I am using a few fans though so I’m not completely suffering.

Most of us have seen at one time or another the waves of thermal energy rising from a fire or candle. If you haven’t try looking at a fire which is back lit and then squint at it. You’ll see the rising wavy lines going up. Thermal energy. Still not convinced place a white sheet of paper about 12 inches over a candle … by the way be prepared to run for a sink of water.

So urban areas tend to be hotter than rural areas, but not just any old rural area. Rural areas with a healthy does of trees.

We chop a lot of them down in the urban area and plant raggedy little ornamental trees. Yes they are trees yes they do make it look a lot less industrial but do they really cool or shade must of anything. Not really.

Larger urban area create there own updrafts. The sun hit all the concrete, glass, metal, asphalt and other heat reflecting surfaces. Not just some but millions of square feet of material now all that heat, thermal energy rises. Sending everything up. Any moisture entering the area ends up going up before it can fall down. What usually happens is rain just misses urban areas getting buffeted around by these huge up drafts.

How much does this contribute to global warming… I don’t know but that isn’t the point. It’s hotter now in our cities than it was in the past. I worked a road crew one summer, a paid one not a jumpsuit wearing one. Air temperature checks were done every 20 minutes to track the heat and so we were given breaks so we didn’t over heat. The air over the pavement was often 20 degrees hotter than it was away from the pavement . A 90 degree day is 110 on the road. That’s an over all warmer day, warmer cities, warmer planet. However our urban areas aren’t the only problem to the issue, again not about global warming.

It’s about not running my AC. Partly to keep my energy costs down, partly to use less energy, partly to just be less … luxury dependant. Is AC essential not really. So I am not using it. I don’t make my son play along because this is my thing not his. I know less then total commitment is just a waste of time… well maybe but poopoo my plan all you want but I have smaller bills this summer than I did last summer. So it’s working at least partly. I didn’t use my heat much in the winter either, turned it to 62 when I was home and 58 when I left or work. Again didn’t make my son play in my experiment.

Perhaps that makes me a bit strange or weird…perhaps. Believe me I see really off at times so my experiments with using less luxury things seem really not so odd at all. It’s all relative or at least that’s what I’ve heard. I’m not saying do this or not just talking about what I’ve been doing to save some money.

The dingoes got yelled at for dancing …poor dingoes.


Have a great day and play nice in the neighborhood.

Ciao,
