We’re at the tail end of a record heat wave here in Victoria. I believe South Australia and Western Australia are probably in the same boat. It is hot. VERY hot. My house is currently 30°C (at 9am) and my greenhouse reached a whopping 54.1°C on Tuesday. Continue reading

Climate change and changing to suit the climate
Is it real or is it just a hoax?
If it IS a hoax, what is the reason behind the hoax and who does it benefit?
If it is real, how do we sort the truth from the lies? How serious is it? Is it too late?
I only wish I knew the answers but I believe climate change, brought about by man, is real. If it is a hoax it benefits no-one that I can think of bar a few comparatively small companies producing environmentally friendly goods. If we believe it is a hoax however, I can think of a few industries that will reap the rewards (think of mining and drilling).
When I think back to what started my green journey I find it really hard to pin point any particular thing. I remember hassling my mum once about buying bleach and she ended up buying vinegar instead. I remember in grade 6 I think it was, doing an in class assignment where you answered multiple choice questions and it predicted a future scenario for you. Even then I preferred a large house in a small country town with an eco lifestyle. Ok, so I no longer want a large house (cleaning the house never entered my 12 yo mind 😉 ) but the rest of the scenario has pretty much played out to be true. I’ve also had that dream of living on a small acreage in the country for as long as I can remember, interspersed with eco dreams too. For as long as I can remember there has always been some level of environmental sustainability or homesteading about my dreams.
So what kicked it all into high gear then? I’ve already mentioned some of my journey of how it’s not easy to be green but it was probably the film The Day after Tomorrow that really prompted me to start making changes. Now, do I think that there will be 3 big storms to plunge the world into a new ice age? No. Do I think that the film is very over-dramatised? Yes. Do I think that the film makes a good point though? Yes. It got me thinking long and hard about climate change and our precious planet. It got me thinking about the impact that my choices and decisions have upon the planet and although it doesn’t touch on even half of the issues out there (deforestation of our jungles, over fishing, landfill, fossil fuel usage and so on) but at least for me it got me thinking. It got me processing. It made me realise that there is a LOT more to the world than just my little piece of it.
Now as I sit here today it’s a predicted high of 38C degrees (about 29 inside at the moment). It’s still November! The average maximum temperatures for Melbourne in November is 22C although the highest on record is 40.9 on November 27 1894 (info found here). It’s a total fire ban in both the Mallee and Wimera regions of Victoria too – the far north and west of the state where it’s already at severe fire danger (info found here). This is unusual for November in Victoria in my memory at least and I suspect that the odd rumours I’ve heard of a long hot summer may well turn out to be true. And after what Ballan locals have said was a long cold winter… Well it just seems to me, in my very unscientific opinion, that things are changing.
I believe things are reaching some pretty critical levels as far as climate change goes. I mean, from a cursory glance at my dear friend Dr Google, it seems the average temperature of the earth has risen less than a degree C which sounds negligible… But is it? I know the last few years here in Melbourne we’ve had some stinking hot days. I remember the new years we waved farewell to 2007 and hello to 2008 it was still a balmy 35C or 95F at midnight. Just over 13 months later on February 7th 2009 and we saw our hottest day on record, now known as Black Saturday because of the horrific bushfires that raged across our state. It changed our hottest ever recorded Victorian temperature to a whopping 48.8C (that’s 120F) recorded at Hopetown (stats taken from here). Melbourne reached 46.4C or 115.5F (stats taken from here). Even without counting the fires in, it was a pretty rotten day here. Including the devastating fires, it was horrendous.
The point is, the climate is changing and we are going to have to change along with it. I read a wonderful comment this morning on Narf77’s blog The Road to Serendipity about adaption. “I LOVE the positivity of permaculture…no sitting around whinging about how we won’t have citrus trees soon and isn’t it terrible…just straight away looking at the possibilities and adapting. That’s what I prize…adaptation and the ability to look on the bright side. That’s what is noble about the human race…” and it struck a chord. Even if we stopped burning each and every fossil fuel today and set everything right in one fell swoop I don’t believe the climate trend will change overnight. Things have gone too far for that. Arctic ice melting is a prime example. From what I’ve read it works like this. When there is a large amount of arctic ice it reflects back the heat of the sun a lot more, being white it’s reflective, not absorptive. However, when it gets hotter the polar ice melts and then there is less white reflective ice and more absorptive dark coloured ocean to contain the heat from the sun. This in turn melts more of the ice, which in its turn provides more dark ocean to absorb more heat and so on. I’m not sure how that is supposed to stop to be honest because it’s self perpetuating. The melting of the polar ice brings with it warmer temperatures, more water (the melting water surely has to go somewhere although I can’t seem to find anything but arguments about rising sea levels on Dr Google).
We MUST take more responsibility for the environment and try to stop the global warming trend but in correlation with this we need to adapt. I for one am glad we will be raising our elevation from about 17m above sea level to much closer to 500m… Just in case. I also plan to try to grow some plants that are not considered suitable for the Ballan climate – Tagasaste (Chamaecytisus palmensis) or tree lucerne is one such tree. It’s a dry climate plant initially from the Canary islands and doesn’t like waterlogged soil but I am hoping by growing it in a raised bed in the chook pen that it will thrive and help provide food for the chickens. I am also going to try growing sweet potatoes next year. They’re not good in cold climates and not so great in temperate climates either (I tried to grow them a few years back) but I reckon it’s worth giving them a crack inside the greenhouse. I’ll probably also try ginger and turmeric too. The Tropical Hippy, a friend in both the blogosphere and real world who lives in tropical climes is giving sweet potatoes a go now if you’re keen to try them.
For me that adaption is to try and grow things locally so that I can reduce our food carbon miles. If I can’t grow it locally (bananas, mangoes, pineapples and other tropical fruits for starters) I need to weigh up the value of having access to these foods (bananas would be a big loss to my kids) versus their mileage. With many of our tropical fruits coming from Queensland they’re not as bad as they could be, but dates (which we use in cooking and as snacks – a huge loss to me) may well come from Iran or other local countries so their mileage is huge. I guess for me if I can localise as much as possible then buying some things with carbon miles isn’t so bad. I hope that the miles our tomatoes will travel will be about 20 metres from the veggie garden to the kitchen via shanks pony. 🙂 They will then be bottled which will use some gas or electricity in the processing but it’s much less than buying a can of imported tomatoes.
Anyway, this is becoming a bit of an incoherent ramble which I’m going to blame on the heat frying my brain (that’s my story and I’m sticking to it 😉 ) so it’s time to sign off. We’re having a tv day here in the interests of keeping the kids calm whilst being locked inside away from the sun (not my favourite kind of day but needs must).
