No evidence of warmer summers from Wollongong City Council swimming pool attendance figures

I saw this news about repairs to the ocean pool at Austinmer north of Wollongong. I have been interested for a while in the issue of the height of the oldest ocean pool walls and how they might relate to historic survey heights and modern survey heights – on the basis there should be another line of evidence here establishing the rate of sea level rise over a century or more.
Wollongong City Council have www page about their pools and there is a downloadable 9 page pdf report – Future of Our Pools Strategy 2014-2024 –
I thought – surely there must be comments here about sea level rise. Not so – not a word about sharks hoiking themselves over the walls during King tides and carrying off the odd swimmer. But I noticed this gem at the end of a string of bullet points on page 7 –

And earlier in the report was this graphic showing declining attendance figures –

All seems logical to me.

Global warming drives New Zealand Fur Seals into South Australian lower lakes to enjoy the fishing

Saw this on the ABC – Fishermen losing out to seals in SA’s lower lakes – global warming has been claimed to cause just about anything – the John Brignell list of several hundreds of things claimed to be caused by GW.

Could the record expansion of Antarctic sea ice – much hyped lately as being due to warming – be driving the critters north?

Claim only four lemuroid possums found in the Daintree since 2005

I noticed this “lemuroid ringtail possum” story over at Anthony Watts.
It is something I wrote about in 2008 –
“Poster child for climate change” – you be the judge

and again December 2013 –
Recycled five year old story about global warming threatening White Lemuroid Possum
I do not recall in the 2008 or 2013 media anything about there being only four critters left. Perhaps I missed something.
This article from the Cairns Post – Possum a ‘polar bear’ of climate change – a bit odd seeing there are many thousands of polar bears. While Polar Bears are being dragged into this – try this site for information on Polar Bear Science.
Anyway – the Cairns Post article states – JUST four white lemuroid ringtail possums have been found in the wild – Just four have been found since 2005.
I wonder if either of these statements could be true.
Time will tell I suppose.

Macquarie Island mysterious azorella plant dieback blamed on “noticeable change in climate”

Saw this on ABC – Macquarie Island faces new battle against mysterious azorella plant dieback – I thought – bet they blame “climate change” – sure enough

Scientists believe the plant’s demise has been caused by a range of things including a noticeable change in climate. “Everybody who has been going to Macquarie Island for a long time has noticed longer drier periods, changes in the wind direction and the rainfall”

Yet annual temperature and rain data from KNMI Climate Explorer does not indicate significant changes.

Temperature from the father of Global Warming

….and rain does not seem to be vanishing

I am sure it will be at the wrong time though – or maybe the size of the drops is wrong.

Some more info on Azorella -Australian Antarctic Division and from Royal Tasmanian Botanical Gardens

Recycled five year old story about global warming threatening White Lemuroid Possum

I first saw this issue raised in 2008.

Now the ABC are running the same storyline – basically the Daintree is heating due “global warming” and this is causing the White Lemuroid Possum to be endangered.

The nearest current and intact temperature series I can see around the Daintree is at Walkamin Research Station and the warmest months – November to January show little trend over 43 years.

Pindan Post has had something to say too.

Australian Antarctic supply ship Aurora Australis blocked by ice again

Due back in Hobart tomorrow 16 November 2013 the ships webcam at 6am on 15 Nov 13 shows it is heading SSW on the voyage from Davis base to Hobart.

The latest sitrep can be read here –

We have made slow progress over the last 24 hours due to pack ice conditions. This morning the ship was stopped and a decision made to wait for improving ice conditions (which is anticipated) rather than continuing breaking of ice at a snail’s pace consuming significant volumes of fuel. The situation will be assessed over the next 12 hours.

Cheers Tony and Mike

They were icebound on 31st October on the way to Davis – also icebound in 2012.

Maybe global warming is worse than we thought.

Research in progress suggests a link between salt levels in Antarctic ice cores and rain in south-west Western Australia

Thanks to Romanoz for alerting us to this fascinating research – see his comment #5. I now have the 20MB download – Antarctic Climate Change and the Environment – dated November 2009.
Under Atmospheric data derived from ice cores
The last para on page 43 starts – Ice core sea-salt as a potential proxy for mid-latitude winter rainfall variability. The full text on p 43 & 44 is saved here if you click on “Read the rest of this entry” at the end of the post.
Fig 2.8 shows salt content of ice varying from 1300AD and the text says – [ The work in progress indicates that southwest Western Australia experienced periods of higher mean winter rainfall, with high interdecadal variability during 1300 to 1600 AD, followed by lower mean but less variable winter rainfall from 1600 to 1900 AD, which is similar to the past 50 years (Goodwin, in prep.).]

The text ends by saying – [This long record would be of enormous economic benefit to all water users in Western Australia.]

Fig 2.7 shows that in the phase illustrated in panel b, the SW of WA is affected by higher readings of MSLP (mean sea-level pressure) – more finer weather.

So WA water authorities and politicians should take note – there is evidence that pre-1975 SW WA rainfall was not some constant high-rain regime. The post-1975 lower rain regime may be a perfectly normal phase of long term cycles and nothing to do with Greenhouse as they have claimed ad nauseum – Chapter and verse for a decade or more.
