The best informed guesses I can find about what we Australians might need to deal with in direct climate effects are hotter weather, stronger cyclones, a monsoonal rain pattern that moves south, (making it relevant not just to Darwin and far northern Australia but to Queensland and northern NSW too), a lower frequency of strong El Niño and more La Niña – which is good news for the eastern states…
The Bureau of Meteorology says that it’s likely that this will be an El Niño year, drier and warmer. That is, it says, on top of the drier and warmer conditions that climate change predicts anyhow for much of Australia, especially the south east. It brings with it an increased risk of extreme heat. And my ‘470’ research came to the same conclusion as this week’s article in The Conversation – Australia’s…
We’ve done relatively little “renovation” in the conventional sense in retrosuburbia-ing this 1950’s cottage. In most cases, the embedded energy, and money, is more than would be saved by changing an old thing for a new one. This west wall is one of the few bits of real demolishing and rebuilding we’ve done.
Much of the retrosuburbia writing about energy use and energy conservation that I see is about heating, but heating isn’t the issue here. Here, it is cooling, not heating that is the main challenge, even now let alone in the future.
It is tipped to reach 41°C today. That’s 106°F for those of you in USA. Tackling the kind of bad habits and addictions that are disrupting the planet’s climate is hard and scary. Change always is. But how many heat waves, firestorms, floods, tornados, cyclones, tidal surges, droughts, food shortages, and extinctions add up to harder? and more scary?
Summer is a much harder gardening season than winter in Australia. Most years there’s a set of frizzle days sometime over the summer – days when the temperature is up around 40ºC for a few days in a row. It can be really disheartening. Your garden can be looking good one day, then a few days later it’s all fried.
I don’t get frost in my sub-tropical garden, so winter is a good growing season here. It is the frizzle days of summer that are the challenge, when a whole garden can be wiped out in one brutal day. But just like gardeners in frost-prone climates, you develop a range of strategies to work the odds.
