They went to NIWA site. Used the official graph and were given access to the raw data.
CSC(climate science coalition does not provide the raw data to show how they got their graph either? WTF
The fact that NIWA makes the raw data available to groups like this is significant. It also makes the data available to the Public.
So they have nothing to Hide. Are Hiding Nothing.
NIWA climate scientists have previously explained to members of the Coalition why such corrections must be made. NIWA’s Chief Climate Scientist, Dr David Wratt, says he’s very disappointed that the Coalition continue to ignore such advice and therefore to present misleading analyses.
source< br />
NIWA's analysis of measured temperatures uses internationally accepted techniques, including making adjustments for changes such as movement of measurement sites. For example, in Wellington, early temperature measurements were made near sea level, but in 1928 the measurement site was moved from Thorndon (3 metres above sea level) to Kelburn (125 m above sea level). The Kelburn site is on average 0.8°C cooler than Thorndon, because of the extra height above sea level.
source
In their own words, NIWA describe their logic thus.
Where there is an overlap in time between two records (such as Wellington Airport and Kelburn), it is a simple matter to calculate the average offset and adjust one site relative to the other.
Wellington Airport is +0.79°C warmer than Kelburn, which matches well with measurements in many parts of the world for how rapidly temperature decreases with altitude.
Thorndon (closed 31 Dec 1927) has no overlap with Kelburn (opened 1 Jan 1928). For the purpose of illustration, we have applied the same offset to Thorndon as was calculated for the Airport.
The final “adjusted” temperature curve is used to draw inferences about Wellington temperature change over the 20th century. The records must be adjusted for the change to a different Wellington location
Now, it may be that there was a good and obvious reason to adjust Wellington temps. My question remains, however: is applying a temperature example from 15km away in a different climate zone a valid way of rearranging historical data?
And my other question to David Wratt also remains: we'd all like to see the metholdology and reasoning behind adjustments on all the other sites as well.

The problem is that third world nations are going to continue illegal deforestation and they will sell it to those who buy it. From the Middle East, to China, to Russia, etc.
How is anyone going to make these people stop deforestation?
How is anyone going to stop China, Russia, India and others from polluting the world without any regards for the environment, when all they want is to control the world economy, or at least to be a big part of such control.
China, Russia, India and others have emphatically stated they will NEVER accept any emission caps.
The worse polluters in the world are these countries, yet the UN, and environmentalists want for western nations to be the ones to pay for what others are doing. At the end the bill will be paid by the PEOPLE, meanwhile there is more control over people and countries like China, Russia, India, and some others keep polluting the world.
The Kyoto protocol and other similar protocols the UN, and environmentalists want to introduce will not do anything in favor of the environment, it will just distribute wealth to the rich elites in countries that will never accept any emission caps, or any environmental problems to get in their way.
How is that going to help anyone?
China announced plans Thursday to cut its carbon emissions by up to 45 percent as measured against its economic output – a target aimed at keeping its surging growth while still reining in pollution.

Are scientists underestimating nature's ability to absorb CO2?
Posted On: November 10, 2009 - 6:50pm
New data show that the balance between the airborne and the absorbed fraction of CO2 has stayed approximately constant since 1850, despite emissions of CO2 having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now.
This suggests that terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected.
The results run contrary to a significant body of recent research which expects that the capacity of terrestrial ecosystems and the oceans to absorb CO2 should start to diminish as CO2 emissions increase, letting greenhouse gas levels skyrocket. Dr Wolfgang Knorr at the University of Bristol, UK, found that in fact the trend in the airborne fraction since 1850 has only been 0.7 ± 1.4% per decade, which is essentially zero.
The strength of the new study, published online in Geophysical Research Letters, is that it rests solely on measurements and statistical data, including historical records extracted from Antarctic ice, and does not rely on computations with complex climate models.
Surprise In Earth's Upper Atmosphere: Mode Of Energy Transfer From The Solar Wind

"Its like something else is heating the atmosphere besides the sun. This discovery is like finding it got hotter when the sun went down," said Larry Lyons, UCLA professor of atmospheric and oceanic sciences and a co-author of the research, which is in press in two companion papers in the Journal of Geophysical Research.

Did you know that increased level of CO2 allow for plants to use water more efficiently? At about 1,200ppm to 1,500ppm plants, trees, and entire green ecosystems use less water, and still grow up to 60% bigger, and produce more harvests.
Remember that part of the goal the Socialist elites have is for "population control." What better way to control the population than by not allowing enough food to be produced because of lack of atmospheric CO2?
It is happening. No one can account for apathy. But many people feed it in this debate.
Climate Change is happening. Perhaps you remember that back in 2004 I was urging people to move out of coastlines, under the name Muaddib. But the thing is MOST people won't move. Look at New Orleans, people should be LEAVING that area yet even after knowing what can happen they stay there.
They would probably have to put a specific tax in there somewhere to pay for it or use massive amounts of Govt spending that would then be passed on in taxes or interest rates, and once that would happen, sKeptics would pop up questioning the science and the policy of having to Move people because there is climate change. Sound familiar?
It would create millions of jobs if cities like New Orleans were moved, or build inland to avoid flooding, but that is not going to happen until New Orleans is destroyed by nature. It is the nature of many people.
How alarming, you sound like Hansen.
The same happens with people in California. I have visited California and lived there for a week during a vacation and I would never move to that place. It is a ticking bomb.
So it is a fact now.
But the fact of the matter is that mankind is not the cause of Climate Change.
There have been several threads posted by others and myself that show the Earth's magnetic field an dthe large fluctuations it is going through haven't occurred for tens of thousands of years.
This increase would also effect all the CO2 in the atmosphere too. Would it not?
The interplanetary field of the Solar System is weaker than it has been for a long time, and it is allowing more charged particles and radiation to enter the Solar System and to affect planets like Earth, including the climate.
Scientists found that even when the Sun's defenses are down SOMETHING ELSE is warming the Earth's atmosphere, and it is happening because of the weakened interplanetary magnetic field, as well as the weakened magnetic field of Earth.
Just wondering, photon radiation is roughly 3K or -270 degree Celsius in space is it not.
Not only that but more interstellar dust, alongside more charged particles, more plasma, etc is entering the Solar System and their levels are increasing exponentially.
All of it now!
ALL of the above causes changes in the Earth, including Climate Changes.
This is why people don't move from places like New Orleans and California.
We can only adapt to what is happening, NO ONE can "save the Earth."
The Earth doesn't need saving, it is going through a process that has occurred before and there is nothing we can do about it except adapt and survive.

Published Sunday in Nature Geoscience, the same study shows that the smaller but less stable West Antarctic icesheet is also shedding significant mass.
Scientists worry that rising global temperatures could trigger a rapid disintegration of West Antarctica, which holds enough frozen water to push up the global ocean watermark by about five metres (16 feet).
And that is because there is cooling? Ice is melting and breaking of because it is colder!

Really, I have seen skeptics in the MSM for 10 years now. So I should stop listening to them. Cool. Thanks for that.
Ok.NOTHING THE MAINSTREAM MEDIA SAYS ABOUT GLOBAL WARMING IS TRUE........
global warming is one the major lies in their end game plan to depopulate the planet by 80/90 per cent...without the global warming hoax there is no carbon tax etc.....
Yes it is.

Let's hurry up and throw 200 million people out of work worldwide
and see if that helps.
The tax is specific. So is the spending. In my country anyway.
Let's also raise everyones taxes and spend it on whatever.
Doing nothing will cost us more. It always has.
Maybe then the ice will stop melting in Antarctica.
I think we should build a new prison on Antarctica.
Put those lying liberal scientists in it for 20 years.
The whole gist of my original reply is that the group you got your belief from does not explain how they got their graph. You don't ask them to explain it. Why?
So while you are happy to accept their explanation, I believe they've got far more explaining to do.
Especially when other sites raw data show a mild NEGATIVE trend over thier lifespan, then unexplained adjustments show warming?

NIWA has explained what they do. It just is not enough for you. They even mention explaining it before to the Coalition, so why would they bother answering AGAIN, baseless attacks.
Originally posted by atlasastro
The adjustments are explained. They are also explain here on ATS.

The Climate Science Coalition has been involved in manipulating and distorting science in other ways. Like the Manhattan Document.
Why are you not questioning ALL the sources in relation to the NIWA situation?
And you just believe that. How many stations did they use? All of them or Just one? Why do they claim that no data needs adjustment given known changes in stations etc. It is a known fact that jut a simple rise in elevation can alter reading by over 1 degree. They need to show that the adjustments are irrational and fraudulent. They simply do this by claiming no adjustments are necessary, when they are.

I guess you did not look at the links I provided. They clearly say they used the raw data available on NIWA's web site. They have made no adjustments to the raw data, so why would they need to explain it? Do they need to explain how to plot a graph?
Yep.
Even so, they have said they will release their data and show where there was some assumptions that needed to be made. They concede that they may have made errors, which is why they are explaining it.
They use Wellington as an "example" in the press release. The Climate Science Coalition questions that there are SEVEN adjustments to stations. They have explained it, and more, you just won't get these explanations from Dunlevy et al at NZ Climate Coalition Blogs.
They would have given the same explanation they did in their press release. They explained ONE of their sites, then said they don't need to explain the rest, as they use "internationally accepted techniques". Even then, their explanation for Wellington is a little dubious (see previous post). So yeah, your right. That's not enough for me, or many others for that matter.

Renwick, Salinger and Niwa chief climate scientist David Wratt hit back at the claims of manipulation.
Wratt said Niwa climate scientists had previously explained to members of the coalition why such corrections had to be made. He was disappointed they continued to ignore that and present misleading analyses.
Salinger said adjustments were made for legitimate reasons, such as changes of site.
"I haven't seen this work but it will be b......., because I have worked on this for many years.
"When I was doing my PhD, looking at the record up to 1975, there were at least 50 to 60 climate stations started in the 1930s that, before we did anything, 90 per cent of them showed warming."
Renwick said there were several reasons for adjusting the temperature record, including introducing new thermometers or sensors to a weather site, and changes to its exposure caused by growing vegetation or urbanisation.
For example, the Wellington figures had to be adjusted down when the official weather site moved from the Thorndon waterfront to Kelburn.
Dude, read the actual PDF, they only use the overlap period to get a cooler average. The reason why they only use the overlap is because if they where to trend out the South and the Higher station, the south historically is warmer, so what they do is find a point that show cooling and then make a claim that this is typical for the entire history.
You would question the reasons for adjusting if it showed cooling, would you not?
Here is a link to a pdf where NZCSC have taken a look into one of the sites, Hokitika. They have shown their methods and it raises further questions, which are yet to be explained. For example, it is shown that adjusting data for height (as in Wellington) isn't neccessarily an accurate method.
www.climateconversation.wordshine.co.nz...
Here we have a station almost at sea level (Hokitika South) reading (during the overlap period 1964/5) on average 0.3ºC colder than the other at 39 m altitude (Hokitika Aero).
From the Horses mouth. NZ Climates Science Coalition.
All the adjustments increased or even created a warming trend, with only one (Dunedin) going the other way and slightly reducing the original trend.
Here is a link to multiple site adjustments. They use wellington and the Airport to show how even though sites move, the temp trends are the same with a variation due to relocation.
This is refering to the other sites apart from Wellington. And as far as I'm aware, they have not explained their adjustments for these sites. However, if you could point out where they have, that would be great to clear up the matter.
Well get familiar with it. And research The Climate Science Coalition in NZ. It is the same dribble coming from the Climate Science Coalition that you are accepting now. They tried this in 2006. Is it not funny that it is happening again on the back of the Hadley Hack and Copenhagen?
I'm not entirely familiar with the Manhattan document, so I can't comment on that, sorry. However, I agree that we should be questioning ALL sources, including NIWA, instead of accepting broad, generalised statements as an acceptable explanation.
