cheap pumps cheap pumps CSIRO website offers raw greenhouse data 20



ELEANOR HALL: While politicians in Canberra debate the merits of a popular vote on the carbon tax, the CSIRO this morning launched a website that will allow people to see the raw data on greenhouse gases for themselves.



Scientists say the site will reveal the levels of carbon dioxide, methane and nitrous oxide being recorded in the atmosphere each month at a site in Tasmania.



MARY GEARIN: The CSIROs new website will report unmodelled, raw measurements directly to the public, it says, so people can make up their own minds about climate change.



But the leader of the bodys Changing Atmosphere research group, Dr Paul Fraser, denies that its a response to sceptics.



PAUL FRASER: This site has nothing cheap pumps to do with criticism about climate change science directly. I mean we have in CSIROs greenhouse gas records one of the worlds best records of greenhouse gases.



We have been anxious for some time to share those data with as wide a community as possible. We just think it a good time to make our data publicly available, no strings attached, no outside interpretation and then setting up a dialogue to discuss what we think the data means.



MARY GEARIN: Peta Ashworth, the leader of CSIROs Science into Society Group says her research shows the majority of people are keen to learn more about climate change science.



She says her latest survey of 1,600 people only 7 per cent did not believe climate change was happening.



PETA ASHWORTH: I think there is a certain amount of people that do remain sceptical and I think we have to respect their opinion. From the point of view of where those voices come from, I think it changes.



So from my perspective what we are looking at is I think this website in itself provides another opportunity for evidence that people can go to, to try and clarify some of those sorts of things.



MARY GEARIN: The public will soon be able to download monthly measurements of carbon dioxide, methane and nitrous oxide as recorded at the Cape Grim Baseline Air Pollution Station on Tasmanias west coast.



Dr Fraser says its one of the most important measuring sites on the planet.



PAUL FRASER: We decided many years ago in the 70s to go to a site which we thought would be representative of a large volume of the southern hemisphere. We decided to go to a site on the west coast of Tasmania and we have shown that you can go right around the southern hemisphere with these latitudes and youll measure virtually identical concentrations to what we measure at Cape Grim. So they do represent the background concentration outside of the tropics in the southern hemisphere. So thats probably about a third of the global atmosphere.



Now what we found and perhaps a little cheap pumps surprisingly, is that in fact all of the long term trends that we see and the interannual variability we see at Cape Grim reflects very well whats going on in the global database.



MARY GEARIN: Dr Fraser says scientists are not concerned that providing monthly data will lead the public to shorterterm sense of climate change.



PAUL FRASER: Weve decided to go with monthly mean data because we wanted to show that there are variabilities in the data that we need to be aware of like seasonal variability. It doesnt make much difference in a sense what time frequent domain we report the data in because we are reporting all the data. We are not being limited by the fact that we are reporting monthly mean data.



Perhaps this is something we should think about on the site. We can convert our data to annual means and decadal means if we want to or the public can do that themselves, you know, relatively easily and that is the beauty I think of providing them, the public, with the basic data. If they want to calculate the annual means or the decadal means, they can do it and come to their own conclusion about what is happening on decadal time scales or on century time scales or annual time scales.



MARY GEARIN: But while the CSIRO has concluded that much of the global warming of the past 50 years is due to human activities, Dr Fraser says this site wont necessarily prove that before peoples eyes.



PAUL FRASER: Simply seeing an increase in concentration in the atmosphere doesnt tell you where the carbon comes from. I mean it has a clue, you have a clue because you can estimate well how much of that carbon is in the atmosphere and what does that represent in terms of what we know about the burning of fossil fuels and you can see that the numbers are not wildly different. So there is some indirect evidence if you like of the role of fossil fuels. cheap pumps
