🌨️ More than a hundred million on alert for monster winter storm

100M!  That's almost 1/3rd the population of the FSoA!  ::)

Here on the Last Great Frontier after a solid MONTH of sub-ZERO temps, we finally got above zero, at least on the Farenheit scale.  Still a ways to go before we pass the Freezing Point of water though.

I wonder how Roamer is doing on the Dairy and WHD in Minneapolis?  ???

The kids are driving to Chicago today.
What makes the desert beautiful is that somewhere it hides a well.

Good thing C5 is down in El Salvador!  Or was it Guatemala?  Nicaragua?  ???   :icon_scratch:

At least there is less shoveling to do down there.  You only need to dodge bullets!  lol.

Almost 45 degrees in Avalon as city heads to forecast maximum
At beachside Avalon – about 60km west of Melbourne, near Geelong – the mercury has hit 44.3 degrees.
In Melbourne, the temperature is quickly heading toward the forecast maximum of 43 degrees. It is currently 44.2 degrees.
The humidity remains quite low at 21 per cent.

Melbourne will swelter through 43 degrees today and 33 degrees tomorrow.
Victoria is set to see its highest demand for electricity since January 2014 and residents are being asked to 'power down'.
For up-to-date fire information, go to VicEmergency.

Empty nets and tropical fish in Tasmania as climate change hits Southern Ocean


Rising temperatures and climate change have been blamed for the failure of stocks of some of the most popular eating fish in Australia’s Southern Ocean to recover from declines despite more than a decade of protection.

The troubling findings come as new modelling from the CSIRO shows further temperature rises already “locked in by past emissions” could see fish stocks fall by another 20 per cent within the next two decades.

Dr Alistair Hobday, a principal research scientist at the CSIRO, said there was “no doubt” climate change was an important factor in the failure of some over-fished species to recover.

A report by the government’s Fisheries Research and Development Corporation has found ocean temperatures increased by nearly 2 degrees over the past 80 years in the Southern and Eastern Scalefish and Shark Fishery, a “global hotspot” that was warming at almost four times the global average.

The affected region sweeps from the lower east coast of Western Australia across Victoria and Tasmania to the Queensland-NSW border - one of the most productive ocean zones in the country.

Stringent new controls were introduced in 2005 to try and reverse the effects of long-term over-fishing in the area but new data shows that by 2015-16, commercial fishing operators were still catching less than half their allowed quota for more than two-thirds of species.


“When you reduce pressure [from fishing] you expect the stocks to improve. If you are catching fish and then you stop catching fish, the numbers of fish should come back. But they haven’t, and climate change is stopping that recovery in some cases, such as for jackass morwong, eastern gemfish, and blue warehou,” Dr Hobday said.

“Historically over-fished species (eastern gemfish, school shark, blue warehou and most recently redfish) have shown little sign of recovery despite over a decade of the lowest catches on record resulting from significant management changes under ... rebuilding strategies,” the research report found.

Tropical fish and other species from northern waters are now being seen in the southern ocean along with more than 100 other marine species which have been migrating. Pink snapper for example, are increasingly common in Tasmania waters, while traditional cool water fish are being pushed further south. Species of sea urchin and octopus better known in NSW and Victorian waters are now prevalent and problematic in Tasmania.

What role does climate change play in the changing composition of fish in Victoria's waters? Andy McLaughlin of McLaughlin Consolidated Fisherman believes there are other, more immediate, threats to the industry.

Of the major species sought by fishers, only flathead, gummy shark, pink ling and school whiting were returning catches of about 80 per cent of the quota.

Climate change not only increases water temperatures but also boosts acidity, reduces nutrients, and changes water currents. Oxygen levels also decline in warm water, which means the ocean can support fewer fish. The interaction of these factors forces shifts in the feeding, breeding and travel patterns of some fish species.

The FRDC report, which was produced in cooperation with fishing industry representatives, suggests that other factors that could be affecting catch rates include reduced fishing grounds from the growth of marine parks, the declining number of boats in the fleet, and increasing operational costs limiting the ability to fish.

Study participant Simon Boag, executive officer of South East Trawl Fishing Industry Association, Southern Shark Industry Alliance & Small Pelagic Fishing Industry, said that while the industry accepted the science of climate change, many working on the water had not yet seen the practical effects.

Fish in danger

“What they see is huge variations either way - strong currents, weak currents. We have seen the emergence of stocks of fish that have never really featured before and then they go away again."

“I think this is one of the reasons that we haven't really come up with a strategy as an industry to deal with climate change - we don't really know if things are going to get better or worse. The costs of [fish regulation] are much more extreme and much short term and real, than the long term slow and steady effects of climate change.”

In contrast, Dr Hobday said the fishing industry is increasingly of the view that climate change was exerting a noticeable influence: “Like smart farmers fishermen recognise the inescapable changes happening around them.”

The latest modelling from the CSIRO says climate change will be responsible for a damaging 1 degree rise in average water temperatures by 2040 and likely increase the intensity of extreme events.

“The majority of models also indicate that many of the [species in the SESSF] may decline in abundance by 20 per cent or more as a result of climate-related changes,” the soon-to-be-released report says.

Among those to be rated at a high risk of being affected are orange roughy, oreos, blue grenadier, southern rock lobster, abalone, marlin, and several species of shark, with some species anticipated to see drops in stock numbers of up to 50 per cent.
