Dear All,
In today’s Age newspaper, “Fears of ‘worst shark season’ ever as seas heat up”, see

Back in the 1960s I can recall shark attacks being rather common in Melbourne’s Port Phillip Bay. Temperatures were lower then …
Cheers,

“Back in the 1960s I can recall shark attacks being rather common in Melbourne’s Port Phillip Bay”
Indeed they were – in the 50s also, a radio station had a fixed wing aircraft on constant patrol during summer months, to report sightings.
As for temperatures being lower, I haven’t noticed.
I happen to know Peter Galvin who was mentioned in the article. He still has nerve damage and has to wear a brace.
more whales = more shark food
more shark food = more sharks
more sharks = more people eaten
lets close the loop; perhaps we should eat more whales?
He’s a self appointed ‘expert’.
Back in the 50’s the bay was in much better shape, with more food for sharks.
>lets close the loop; perhaps we should eat more whales?
Nah, let’s just tie those that make such stupid comments to drum lines and see what large predators we can catch.
I feel sorry for those attacked by sharks and injured but you don’t have to go in the water. I don’t it is an incredibly dangerous substance no matter what temperature it is. Due to the concerns expressed on this blog and others I have been looking at what GW can do.
I found this http://nujournal.net/core.pdf and have been awake all night with the worry. Then I found this http://environment.newscientist.com/article/dn11555-global-warming-will-make-earth-spin-faster.html
no wonder I am tired there is less time to sleep.
Can’t some United Nations committee figure out how to turn jellyfish into tasty morsels for sharks and take care of two problems at once? It only takes a consensus.
I disagree completely Woody.
The UN IPCC should be trained in shark whispering, a skill they need because all we have heard, is they’re the sky is falling mantra yelling for a decade, a little bit of quiet debate would be appreciated for a change, preferably with sharks.
That way two purposes are achieved, one they can see for themselves around tourist locations that the third stories in high rise hotels are not underwater, that their predictions were wrong originally and remain wrong. They of course will not be in wild pristine places because we all know their fondness for 5 star accomodation in tourist meccas as places to discuss doom and save the planet with a nice little Jerboam or two.
Two they can provide a real public service by either training sharks thru whispering not to eat people or by providing the sharks a diet choice if they fail as they usually do, IPCC blotocrat nice and handy or a fleeing tourist involving a bit of a chase.
Just trying to assist the climate effort as usual.
Sorry Travis, just having a bit of fun 🙂
That you might get you leg bitten off by a shark whilst surfing is of no concern of the government, only between you and your health insurance company.
Oceans warming makes the earth spin faster? As well as the known variation in rotation associated with sunspot activity and solar flares, implying that the earth’s rotation is not much different to a homopolar motor.
Of course this has nothing to do with sharks and Port Phillip Bay but I suspect that given the tenuous link that oceans warming linked to earth spin, and the other link that warm oceans means more shark attacks, one could then infer that if the earth spins faster we get more shark attacks.
This must be true because the IPCC uses the same reasoning, or least the 52 scientists who form part of the real IPCC group might well do.

Not so funny Forrester when people actually subscribe to such rubbish.
Shark attacks are of concern to the government, hence the pointless nets we have at select spots. Doesn’t matter about endangered and protected species being killed in them along with their reknowned failings, fear of an attack should any nets be removed is enough to keep them in place.
Sorry Forester, mispelt your name – not done out of disrespect.
Travis,
I don’t think the government should have anything to do with shark nets. If the local landowners or businesses want to erect shark nets and pay the entire cost then they can do what they like.
