  1. 'You can't keep arguing this is just a cycle': Farmers struggling to manage impacts of climate change

     /

    Peter Mailler is a third-generation farmer but if the effects of climate change continue on their current path, he doesn't expect anyone will be farming his 6,000-acre property near Goondiwindi in the future.

     

    "You can't keep arguing that this is just a cycle," he told 7.30.

    "Yes, there are dry periods and, yes, there are wetter periods, yes, there are warm periods, yes, there are cool periods, but we have shifted the averages.

    "The baselines have moved to the point now where we are unable to manage the impacts of those extreme events in that set."

     

    And with the Intergovernmental Panel on Climate Change (IPCC) containing dire predictions about reaching the critical 1.5 degrees of warming by 2040, Mr Mailler is not sure what he will do.

    "We're running out of tricks," he said.

    "My bet is that high temperatures are here to stay and that is a serious threat to how we farm and how we manage that lack of rainfall."

    Farmers interested in 'science and fact and evidence'

    Farmers see the effects of climate change firsthand, and many like Mr Mailler are now convinced the predictions are correct.

     

    Even the peak body, the National Farmer's Federation (NFF), now says it's not a matter of whether climate change is real, but what to do about it.

    "Farmers look at science," NFF president Fiona Simson told 7.30.

    "We are very interested in science and fact and evidence and we think now there is plenty of evidence on the table that climate change is a factor that we're going to have to deal with here in Australia.

    "So let's make sure that we can incorporate it into our policies in a way that we can continue to be productive and profitable, where we can continue to be sustainable."

    Ms Simson runs a cattle station near Tamworth in NSW.

    "We've been here for 90 years and if we look back over the 90 years, we've seen a series of droughts come and go," she said.

    "Right now I think farmers certainly are looking at the climate change and work that's been done on climate change and the heating of the Earth, and they're thinking about how that will affect them on farms."

    Mr Mailler believes that effect will be dramatic.

    "Australia's probably more exposed to the effects of climate change than a lot of other places," he said.

    "We already operate in some of the most volatile conditions in the world and climate change means those conditions are going to be more volatile and more extreme."

    And he rejects the argument that Australia's emissions are too small to make a global difference.

    "If we don't show leadership and start to be proactive, then who will?

    "It's pretty simple."

    Success 'in spite of the politicians'

    Mr Mailler was a National Party voter until he founded his own party to run against Barnaby Joyce in last December's New England by-election.

    "We're not going to get a coherent policy around drought if we don't deal with climate," he said.

    "We've got no chance of getting a coherent policy around climate if we have people who won't admit there's something here that needs to be done."

    Sick of waiting for leadership from Canberra, his family has come up with its own solution.

    His parents have built a solar farm on their property and are selling electricity back into the grid.

    "It's producing enough power for about 1,370 homes," he explained.

    "That's most of the homes in Goondiwindi, which is literally just across the river."

    And it is succeeding despite all the obstacles.

    "There's some irony here because, in spite of the Government restriction and obstruction and everything else that's going on, this investment's making money and it's good for mitigating climate," he said.

    "So it ticks all the boxes and it's happening in spite of the politicians."

    He is not so upbeat about the farm.

    "My farm, on the other hand, won't survive and can't be justified the way things are going at the moment," he said.

    The only farm he is confident will make a profit is the family's solar farm.

    "Absolutely," he said.

    "Better money, safer money, easier money."

  2. I've sent various quarry materials to be tested for radionuclides, not phosphate resources though. Not uncommon across a range of rock formations. 

     

    Think commercial tobacco in that context and see where your mind wanders.....

  3. You'll have no problems with hydrogen peroxide in that application .... Shouldn't need it though, although it was pushed in hydroponics. 

     

    A systemic insecticide/fungicide  however needs careful consideration.

     

    Rooting hormone depends on the auxin used. But in general the concentration and amount is insignificant, and there is little chance of accumulation. 

     

    Dont do lines of rooting powder:wink:

     

    Another thing people forget is the growing media and fertilizer which can contain  levels of heavy metals that can accumulate. always pay to check the metals disclaimer on fert, lawn food is an example. 

     

    Cheap arse potting mix is not made up to standards and can be made from materials unfit for food production.

  4. Here's what climate change could look like in Canada

    Climate change is here, experts say, and Canada can expect to suffer the consequences.

    The effects of a warming planet are going to be felt from coast to coast to coast. And, if we stick to a "business-as-usual" scenario — no change to our emissions — it's going to happen a lot sooner than scientists initially thought, according to a recently released Intergovernmental Panel on Climate Change report.

This summer, British Columbia experienced its worst fire season on record. In August, two brief thunderstorms caused widespread flooding in Toronto, bringing the downtown core to a standstill.

     

     

    With a warming planet, we can expect to see more events like these, experts say.

    "People say, well gee, the world's warmed up by 1 C in the last 135 years, but there are parts of Canada that have warmed in some seasons by four, four-and-half degrees in a 70-year period," Environment Canada's senior climatologist, David Phillips says. "So twice as much in half the time."

    B.C. experienced its worst wildfire season this year, with more than 13,000 square kilometres burned. (B.C. Wildfire Service)

    The greatest differences are seen in the north and the interior of continental coast in the west. The region with the greatest warming in 70 years is in the Mackenzie area of the Northwest Territories where temperatures have risen by between 4 C and 5 C in some parts.

    Nationally, the summers have warmed by more than 1 C, with winters warming closer to 1.4 C.

    "There are communities on the coast where people are experiencing sea-level rise, erosion and flooding," says Catherine Abreu, executive director of the Climate Action Network, an umbrella group of environmental organizations. Indigenous communities "are experiencing a loss of their way of life because of climate change. So, the impacts are real globally, and they're real here in Canada."

    While it may seem like eastern Canada isn't seeing much of a change, it is, and it's catching up to the rest of the country. Rather than the change occurring during the past 70 years, it has occurred over the past 10 or 15, Phillips says.

    "There's no region of Canada that's been left out in the cold." 

    Canada's future

    What does the future hold for Canada?

    Phillips used models based on a "business-as-usual" path. Using the median, the models (run by the Laboratory of Mathematical Parallel Systems, or LAMPS at York University), Phillips says people living in Toronto could see 51 days a year above 30 C by 2050 and 77 by 2100. The current average is 16.

    But just because temperatures are on the rise, doesn't mean Torontonians will be done with winter completely. While Toronto gets 16 nights of temperatures reaching –15 C or lower, they'll still get 4 by 2050 and 1 by 2100.

     

     Torontonians might not want to celebrate just yet, however: those warmer temperatures bring increased chances of freezing rain events.

     

    In Toronto and Montreal, there could be close to a 50 to 60 per cent increase of these potentially disastrous and costly events.

    In the Prairies, growing days are expected to lengthen. That's good news for farmers, but there are also negative consequences. 

    "Some regions might benefit from longer growing seasons, but at the same time you have the impact of increased wildfires, for example, the smoke pollution that comes with that and the CO2 emissions," said Felix Pretis, an assistant professor at the University of Victoria who studies the economic impacts of climate change.

     Pretis said that the recent IPCC special report that compared the outcomes of a global temperature rise of 1.5 C versus 2 C is a stark reminder that there could be dangerous and costly outcomes. 

    "The report … sends a really strong message that the two degrees that we talked about previously is not really a guardrail anymore, and that we should be very careful about the future," said Pretis.

    Costs

    Canadians may revel at the prospect of warmer weather, but with that comes a price — literally.

    "In Canada, now, the expression of extreme weather risk, the number one negative manifestation by far is flooding," said Blair Feltmate, head of the Intact Centre on Climate Adaptation at the University of Waterloo. "Flooding is the most expensive cost in Canada to extreme weather by a country mile, and specifically, basement flooding.

    "This is real on-the-ground stuff that is costing us right now."

    A brief but soggy thunderstorm in August flooded Toronto streets, costing the city roughly $80 million. (@earthisanocean/Twitter)

    Blair notes that, from 1983 to 2008, the cost of catastrophic insurable events annually ranged from $250 million to $500 million. Since 2009, however, in eight out of nine years, these costs have ballooned up to $1 billion or more a year, with a $1.8 billion average.

    Pretis believes that part of the problem stems from the ways scientists are conveying their message about the consequences of a warming climate.

    "I'm concerned about the lack of policy response," Pretis said. "I think there's a big challenge also how the scientific community conveys these findings to policy makers … I think we need to carefully translate these findings into local impacts that policymakers can relate to."

    The message is clear, he says: Canada needs to prepare for the future.

  5. Too many things... 

     

    The most profound one was a bird of a type I've never been able to identify (I'm familiar with my environment a wren type though)  that came down to me in a powerful bit of bush I was trying to quickly move through. It stopped me in my tracks and berated and chastised me severely  with such a range of vocalizations and gestures for probably 20 or 30 minutes ... That one was the turning point of leaving years of heavy gear use behind. 

     

    Currently have dusky robins tapping on my windows.... I'm sure they are telling me it's time for action(what action I'm yet to pin) . Persistent buggers (Edit - it is a time for action, what- is the thing)

    They grow well round the coast, they won't survive a lot of places inland Tas unless a warm protected microclimate, or concrete jungle. 

     

    Frost they don't tolerate well, so it's impossibro at my location....i did try.. A few times....Maybe a few more... Lol
