stick to the point. this 'explanation' wants you to believe that heavy rains in australia lowered the worlds oceans by 10mm. But a drought doesnt RAISE them? and of course heavy rains in other parts of the world never does this?
The argument is silly because it is the classic example of casting about for any explanation that 'might possibly, perhaps kinda fit maybe, as long as all our assumptions are right...'
The right answer was 'we don't know...', because we don't.
MOTR, you beleive ANYTHING that supports your orthodoxy and reject all that doesnt.
Hey Longweekend
I had this argument over in the Environmental section.
In the year 2010 & 2011 about 10000 kilometres cube (10000km3) of rain fell on the Australian Terrain.
Very astronomical amount of water to contemplate, i had a hard time getting my mind around it.
This paper apparently says that because so much rain fell on Australia it lowered sea levels by 7mm.
There's only one problem with that and that's this
Quote:Key facts• Around 89% of Australia’s total rainfall evaporates or is transpired by plants into
the atmosphere. Only around 9% runs off into streams, rivers and storages. The
remaining 2% drains below the root zone into groundwater aquifers and, from
there, into rivers.
• Exactly how much rainfall returns to the atmosphere and how much is available to
recharge soil, surface, and groundwater stores depends mainly on the amount of
energy from sunshine, and to a much lesser degree on the type of soil and
vegetation, and the management practices on the land.
• Annual crops and pastures use less water per year than perennial vegetation,
including trees, primarily because of their short growing seasons and shallower
root systems. The larger canopies of native and plantation forests add to their
higher evapotranspiration.
• About 65% of continental Australia’s runoff occurs in far northern Australia and
coastal Queensland. Only about 7% of runoff occurs in the Murray-Darling Basin
where more than 50% of Australia’s water is used

http://www.mla.com.au/files/2089f840-665f-4c3d-834a-9d66008a9009/ So while an unbelievable amount of water did fall on Australia in 2010 & 2011, the possibility of that water all disappearing underground never to be seen again is....
Not True.
All rainwater eventually finds its way back to the ocean, or what's left of it.
A weak excuse to try and protect the IPCC failed forecast once again.
THis is the 3rd time you have told this lie now. Why do you keep doing it?
Nobody claimed that all of the 10,000km3 that fell on Australia was
"disappearing underground never to be seen again" - yet 3 times now you have told this lie. Why?
What you
WERE told - repeatedly - is that it would only take less than 1/4 of the 10,000km3 of rain to be retained on land to lower the world's oceans by 7mm.
Your source says that typically - some 11% of rainfall is not directly cycled back into the atmosphere, but retained on or below land. You source also expands on this typical figure by saying:
Exactly how much rainfall returns to the atmosphere and how much is available to
recharge soil, surface, and groundwater stores depends mainly on the amount of
energy from sunshine, and to a much lesser degree on the type of soil and
vegetation, and the management practices on the landWe know that in 2010/11groundwater reserves would have been depleted after a long period of drought, and also that in those years the amount of energy from sunshine would have been less than usual because of the extreme amount or precipitation received.
THe suggestion that in 2010/11, the amount of rainfall remaining on land was higher than the typical figure of 11% and closer to 25% is not in any way unreasonable.
I suggest that this is why you continue to deliberately lie about claims that %100 of this rainfall was retained on land.
You are not fooling anyone.
