UQ study – Global change takes thousands of years
Story submitted by Eric Worrall
A University of Queensland study into New Zealand glaciers has discovered a huge disparity between Southern and Northern Hemisphere climates, during the natural warming which occurred at the end of the last Ice Age. The new study overturns the previous consensus that glacial retreat occurred globally at the same time – the study shows that glacial retreat in New Zealand was delayed by thousands of years.
According to Professor Jamie Shulmeister, head of the UQ School of Geography, Planning and Environmental Management;
“This study reverses previous findings which suggested that New Zealand’s glaciers disappeared at the same time as ice in the Northern Hemisphere,” he said.
“We showed that when the Northern Hemisphere started to warm at the end of the last ice age, New Zealand glaciers were unaffected. “These glaciers began to retreat several thousand years later, when changes in the Southern Ocean led to increased carbon dioxide emissions and warming.
”This indicates that future climate change may impact differently in the two hemispheres and that changes in the Southern Ocean are likely to be critical for Australia and New Zealand.”
The study described in the press release, in my opinion, has interesting implications for modern climate change. Even if alarmists are right about climate sensitivity to CO2, if the Pacific Ocean has the capacity to retard major climate shifts, for thousands of years, then we have thousands of years to solve any problems we might be causing – which kind of takes the urgency out of the issue.

It looks like the opposite may already be starting to happen Now, S hem will enter a little ice age first then N hem with low solar.
This has to do with S. Hemisphere current sea ice. Many say that increases or decreases in solar do not directly effect earths climate. I have been seeing many connections with solar cycle #24 since it is a quiet cycle and Static of strong cycles is not blocking the True Data.
Maybe Leif can comment on my chart that clearly shows matching dates with increasing TSI and effects on S Hem sea ice growth. Increases in TSI slow S hem sea ice growth. Is it the TSI it self or is the increase effecting the weather pattern with each increase of decrease?

Given the bi-polar nature of the poles that we are seeing right now it’s not too hard to envision differences also occurred in the past.
I take the headline to mean climate is literally not changing in some places. Really? On what time scale?
I’m sick of the two words “climate” and “change” being forced to mean something they don’t.
Frank, my experience with the harrops of this world is that Australia is already balmy.
Raymond, exactly right! Greg’s anti-semetism is not welcome in the slightest, and if he wants to spread his manure, he should just rack off to some like minded Nazi site. Mods, could you please note?
[noted, but we don’t see it as anti-semitism, if it was we’d snip it. he was being sarcastic about how long problems persist without solutions, though using a poor taste example. YMMV, but let’s drop the issue as it serves no purpose, the commenter has been notified that the comment was in poor taste -mod]
must admit i heard only a few moments of the following, but there may be some brave people who would like to hear what Chris Turney has to say now that he back in the public eye once again in case it is relevant to this discussion!
AUDIO: 30 July: ABC Big Ideas: Exploring the Antarctica
The Antarctica is still one of the least explored regions on the globe. But for the past 100 years, numerous explorers have tried to solve the mysteries of this continent. The Australasian Antarctic Exploration 1911-14 provided a unique dataset against which we can compare the changes in weather and sea ice seen today. Last year, Professor Chris Turney led an expedition in the footsteps this exploration – and he presents the initial findings in this talk from the Royal Institution of Great Britain.

17 July: Royal Institution of Great Britain: Return to the home of the blizzard
Chris Turney will present the initial findings of the Australasian Antarctic Expedition 2013-2014, and show how private funding brought the public and science together.
This event will be chaired by Alok Jha, Science Correspondent at The Guardian and soon to be at ITV News.

“The new study overturns the previous consensus that glacial retreat occurred globally at the same time.”
Unsettling news for the settled scientist.

Bravo, great observation. This coincides with changes in the galactic radiation. That is, when radiation increases, the polar vortex slows and ice as well. Large ice growth in July, corresponding to an increase in solar activity and galactic radiation falling. GCR strongly ionizes the atmosphere, especially in the area of the magnetic pole.

This reinforces one of my thoughts as to how ice ages (and LIAs) occur.
1) With the planet tilting the SH a little more towards the sun, the sun experiences a series of weak cycles lowering the TSI.
2) The sea ice around Antarctica expands reflecting away more solar energy and cooling the Southern Ocean.
3) These cold ocean waters flow up the South American west coast creating more persistent La Niña conditions.
4) The effect of this ENSO change creates a near permanent negative PDO.
5) The -PDO leads to polar incursions over land areas in the NH, that is, more polar vortex flows.
6) With lower solar energy in the NH and the cooling effect of the polar winds, we get more snow and ice builds in the Arctic.
7) More snow and ice reflects even more of the solar energy and the planet cools.
When the sun returns to stronger cycles the cooling may or may not abate based on just how much snow and ice have accumulated. With enough ice the planet continues to cool and a full glaciation event takes place. With enough solar energy in the NH the snow and ice melts and the planet starts to warm again.

Changes in the TSI is mainly in the range EUV and CUV which causes a decrease in ozone over the equator. In conjunction with the increase in pressure over the poles gives a north-south circulation in the tropopause.
Mix good science with garbage science and you get garbage science.
Does this work sorta like homeopathy?
Great! Now if we can just move all the folks in California to New Zealand, we’ll be all set. Oh wait, what do we do with the displaced sheep?
Let’s see operating distance the southern jet stream in the Pacific. The stronger the wind, the stronger acts on the circulation in the troposphere.

Let’s see the current temperature in New Zealand and Australia.

Is there a way someone can check the temperature records of a State vs the global temp? I ask because here in Massachusetts we aren’t seeing the warming part of climate change so I wanted to check it against the global temps on NOAA.
The point being is we may be observing a shift in the weather pattern, which in turn affects the climate. And the shift could be caused by a number of factors including the Earth’s wobble and precession.
That is why I would like to check the global against each State to see if I can detect tat shift using temperature records- rainfall records would also be helpful…
With the difference in ocean volumes, the northern and southern hemispheres are different animals when it comes to climate change dynamics, so the present article does have credibility, somewhat diminished by the reference to CO2. Exactly how did they date these ‘moraines’? By carbon dating samples found at the margins? Such a date implies the moraine was exposed at the dated time, but does not exclude it being exposed at earlier times, but that record was erased.

Greg,
This site is primarily used by those who wish to depoliticize science. There are other forums for your particular kind of rant. Take it elsewhere. ”
But he makes a good point, really. Just how much good does it do to kill coal and freeze out fossil fuel as energy sources because of carbon dioxide, when war creates hellish amounts of it? The war in Gaza, the war in Syria, the war in Iraq, and the one in Ukraine have undone any benefit that was ever gained from efforts to reduce carbon dioxide for the last decade. We quickly condemn SUVs that run on gasoline, but we look the other way rather than condemn war as a destructive force in the environment and as a source of pollution. Oops, far better to attack a cow fart than 1000 pound bomb.

Current increase in solar activity will cause next jump (record) of Antarctic ice in August.

No. More like bringing the Ebola virus into a hospital.
“A University of Queensland study into New Zealand glaciers has discovered a huge disparity between Southern and Northern Hemisphere climates,”
Probably because the Northern hemisphere is about 60% water and the Southern hemisphere is about 80%.
Can someone tell me about the melting of the Laurentide Ice Sheet that left behind the Great Lakes of North America. I read somewhere that the melting of this sheet was very fast and sudden.
Is that true, and when did it occur?
Also, why is everyone so worried about the odd degree in global temperature change? Surely the events that led to the creationg and then the destruction of this glacier are many many times more important given the impact they are going to have on civilisation if those changes happen again.
The angle the Globalist warmists will take is to claim that the lack of global warming is due to a southern hemisphere lag. The antarctic ice increase means nothing because of this lag and that global warming is happening faster than ever but the lagging Southern Hemisphere is dampening the terrible, catastrophic effects!!!
Jeff Alberts,
It’s always amusing when people attempting to mock others use false logic in the process. A kind of delicious irony if you will. (Neither the character’s fictional origin, nor the creator’s personal beliefs automatically render the quote to be false.)

is very different from this quote:
