Can someone tell me where the reference point is that they measure the rising sea levels against ?
Just wondering. 
I think it is more prudent to choose when as a datum.
If measuring the height of something, the Datum reference is its lowest known point,
is it not?Unless of course a known average, "mean line", "ground level" or "Horizon" is chosen as a point of reference.
So the last known low. Which would be the last known
major "Ice Age", 20,000 years ago. The sea level and shore line "then" would be our datum reference point, which is known as the
Australian Continental Shelf
My thoughts .... Its just a cycle we are going thru and mother nature will tell us when she has had enough. ie raise the temp or lower few notches as she has done before to tell us who is boss.
We are only visitors here for a short time and as Bigk has mentioned enjoy every day as tomorrow might never come.
I tend to agree.
The Earth has a
very long history of freezing and thawing. I believe repetitive ice ages are/is the earth's cooling and culling and extinction mechanism. A natural cycle, which may or may not vary in its time phasing due to human influences?
Obviously we are somewhere in the warming thaw cycle. Maybe we are helping it? Maybe we are not?
But one thing that is known, is that
The Cold Southern Current that revolves the Antarctic drives all atmospheric climate in the northern hemisphere, 100% fact.It snows over the Antarctic. Ice sheets are formed, which move toward the sea. That sea front melt feeds the temperature of the southern current which revolves around the Antarctic, simply fact.
The lucky layout of Earth's land masses and the dissimilar temperate of the much colder southern current to the oceans above it, is what drives the patterns of currents of oceans above it, and then again those oceans in turn do similar to the seas north of them to create all atmospheric climate in the northern Hemisphere. That is a shortened version, but it is a matter of evidence and fact, more to the point none of the Scientific community disagrees. The most important factor that produces that outcome is indeed the near freezing temperature of the Southern Current, simply fact.
The line of temperature that the defines the northern boundary of the southern current, has just receded by 300 miles. Now that is what I would consider to be the most alarming data to date. Now I have no idea when all the Antarctic ice will be gone. Are we accelerating that process to an irreversible tipping point? Maybe, but I do not know. And that is the 64 million dollar question that is being argued about.
But when/if the cold of the Southern current stops, then the onset of the next ice age will be same as the ones before it. A super storm will start in the northern hemisphere and basically it will just keep going. When it happens? and it will happen again one day, as sure as night follows day. In the scale of time, it will be an "overnight event". Everything there will freeze. Ice sheets will once again form and spread across the northern hemisphere. Those ice sheets will be made from the precipitating H2o that was once ocean water. Hence the lowering level of unfrozen shore lines in the southern hemisphere.
When it happens? There will be a
massive overnight cull of the human race. Life in the northern hemisphere and the Woolie Mammoth will become extinct
well that's what happened. And it will happen again, except for the bit about the Wollie Mammoth becoming extinct again
The oldest living culture on Earth, the Australian Aboriginals who have been in Australia for the 40,000 years or longer, survived. Only 20,000 years ago.
I am honestly not worried about it.
Hey Sera sera.
What will happen next?
Right now?
What I should of been doing instead of bothering with this.
Play with my KDX, and then a cold beer
and get ready for tomorrows efforts
