TOPIC:

Gotta say, I’m sick of all the political stuff here. Some people get off on it and good on them for following something they obviously love debating. But I’d love to read something that wasn’t political. So here is something different. I’d be interested to know if the info is correct.

Rising Sea Levels–The Climate Debate

The seas and oceans to the east of Australia form the largest body of water on Earth.

This broadly connected vast body of water presents a genuine sea level. The Sydney Fort Denison Recording Station provides stable, accurate and genuine mean sea level data.

The following table shows mean sea levels at 10 year intervals and these levels are related to Chart Datum which is at the lowest spring tide level.

100 YEARS OF MEAN SEA LEVELS AT FORT DENISON, SYDNEY:

1914 –1.11 metres

1924 –0.98 metres

1934 –0.98 metres

1944 –0.97 metres

1954 –1.00 metres

1964 –1.09 metres

1974 –1.09 metres

1984 –1.02 metres

1994 –1.04 metres

2004 –1.08 metres

2014 –1.12 metres

2019 –1.05 metres

Accordingly, the mean sea level at Sydney in 2019 is 6 centimetres lower than the mean sea level at Sydney in 1914 when the Bureau Of Meteorology commenced recording Mean Sea Level.

High Sea Levels during Storm, Cyclone & Low Pressure Events.

BBC and ABC commentators have asserted that sea levels may permanently rise by 1 to 2 metres in the next 100 years. 100 years of records on the largest water body on Earth indicates that this is incorrect.

There have always been short period storm and low pressure rises in sea levels. The highest recorded sea level at Sydney occurred during the 1974 low pressure storm. The sea level rose to 30 cm above high spring tide level for one day. During recorded history there has been no indication whatsoever of a 100 to 200 cm permanent rise in sea level.

There will always be short period storm, cyclone and low pressure rises in sea levels in close proximity to cyclone and storm centres. These storm centre rises in sea levels are not permanent.

Ocean swells and storm waves can exceed 16 metres during major storm surge events. It is these massive waves that have caused significant damage to coastal and island communities in the past. It is certain that huge storm event waves will occur in the future and will cause significant damage to the island and low lying communities. Coastline and flood zone protection is the sane answer to storm event damage.

It is polite and essential that the world population should avoid incorrect climate nonsense. We need to divert the alarmist energy to caring for the planet. Cease polluting the oceans. Prevent development of flood prone land and threatened coastal zones that have been, and will always be, subject to flooding.

The erosion at Port Beach that the media and others love to immediately blame on rising sea levels and climate change is one that I struggle to comprehend. That is a stretch of coastline that has been so heavily influenced by man and machinery over the years! You’ve now effectively got the Nor West storms smashing straight into a dead end corner rather than a stretch of beach into a river mouth, of course the storms are going to eat away at the coast there.
I don’t like the way that “environmental “ issues and discussions and policies have been totally replaced by “climate change” issues discussions and policies. It really makes it very decisive and somebody like myself who is quite environmentally sensitive and friendly gets misjudged heavily when I declare that I’m a sceptic of the whole climate change debate. It doesn’t mean that I “barrack” for fossil fuels.

Absolutely brilliant work 58s. Makes an absolute mockery of the climate change alarmists.

Haven’t heard too many Climate Change activists in Perth talking about our heaviest November rainfall in 100 years. The problem with taking about rising temperatures and decreasing sea levels is also that we do not have accurate records for the thousands of years prior to the last 100! There are so many other causes of climate change that are conveniently ignored by the left agenda.

Climate change, the heating and cooling of the earth is a natural occurrence been doing it for hundreds of millions of years, the earth, it vegetation and inhabitants adapt and aclimatise or they die out. The earth has moved into a natural warming cycle, like its done many times before, the difference this time is that humans, as a result of our technology and industies are speeding up the process, a process that will happen whatever we do, it's just going to happen faster, so like before earths inhabitants will need to adapt and change to new conditions and survive or die out.

There's a lot of theories going around about the current climate change.With the rapid meltdown of the North+South Poles polar caps.
The most obvious is overpopulation and the clearing of Topical Rainforests.
Co2 emissions from fossil fuels.
Some scientists think there a massive crack in an ocean floor.Sucking ocean into the earth mantle.
And the elephant in the room which no one wants to talk about.Our 4.6. Billion year old sun.Half way through its life cycle is expanding. As white dewarf stars do.As astronomy experts say.Would explain why ocean levels arnt rising with polor caps melting.

Spot on!!!!!

Now for the next big one....how do we stop the 8 MILLION tonnes a year of plastic mankind puts in the ocean???

That's actually a really big one for me, I would like to see a lot more action on removing plastic waste from the system, if you travel to Asia you see what a huge problem it is floating into beaches and filling rivers, big oil companies have stake in plastic production so they need to be countered.
