<![CDATA[ Communist Party of Australia: Brisbane Branch - Our Blog]]>Tue, 23 Feb 2016 21:00:10 -0800Weebly<![CDATA[Local Members Hit 'Burbs for Mail-drop]]>Sat, 21 Jan 2012 06:58:10 GMThttp://cpabrisbane.weebly.com/our-blog/post-title-click-and-type-to-edit2_Members of the local branch of the CPA have been hard at work in Inala delivering copies of the Brisbane Communist Party of Australia branch’s latest - hot off the presses -  edition of the Bulletin.

The Bulletin is the CPA Brisbane branch's printed newsletter which is published monthly. 

It was a bleary eyed but enthusiastic team which converged in the shopping centre car park in Inala for a 5.30am start. They slugged down a quick cup of coffee before each collecting a wad Bulletin copies, splitting up into pairs, and determinedly hitting the streets. The group fanned out across the entire suburb and devoted several sweaty hours walking from house to house delivering Brisbane CPA’s news throughout the area.
“Inala residents live on large blocks of land so it was tiring in the heat, but they are also a friendly, welcoming bunch and this energized us all,” a branch member noted.  
The mail drop also turned out to be a great relationship building exercise, spurring the members to be right behind future planned community events, including more Bulletin mail drops, for 2012. ]]>
<![CDATA[Cuba's Literacy Triumphs: 50 Years On, Still Changing lives ]]>Tue, 03 Jan 2012 11:13:37 GMThttp://cpabrisbane.weebly.com/our-blog/post-title-click-and-type-to-edit1_AS the United Nations Literacy Decade (2003 - 2012) ends, the number of people in the world who are still illiterate is alarming: 64.7 million children have received no formal schooling and 793 million adults remain illiterate.
Cuba undertook a year-long national literacy campaign in 1961 and proclaimed it a territory free of illiteracy.
But the country's efforts did not stop there. The Yo si puedo (Yes, I Can) program came into being in 2000 following the basic principles of the original Cuban Literacy Campaign. The Yo si puedo project has been implemented in more than 30 countries.

<![CDATA[Cherry-picking Contrarian Geologists Tend to Obscure Scientific Truth ]]>Mon, 02 Jan 2012 00:09:56 GMThttp://cpabrisbane.weebly.com/our-blog/cherry-picking-contrarian-geologists-tend-to-obscure-scientific-truth_Anyone have any thoughts about this?
Full Article is also on our Opinion page and in the Australian.

Mike Sandiford wrote this article for the Australian. He is professor of geology at the University of Melbourne:

GINA Rinehart notoriously claims she has never met a geologist who believes "adding more CO2 to the atmosphere will have any significant effect on climate".
To listen to prominent "contrarian" geologists such as Ian Plimer, you might imagine she never could.

_
"The early sun had a luminosity of some 30 per cent less than now and, over time, luminosity has increased in a steady state.

"The low luminosity of the early sun was such that the Earth's average surface temperature would have been below 0C from 4500 to 2000 million years ago. But there is evidence of running water and oceans as far back as 3800 million years ago." The question is, what kept the early Earth from freezing over?"

Plimer goes on to explain: "This paradox is solved if the Earth had an enhanced greenhouse with an atmosphere of a lot of carbon dioxide and methane."

Here's another quote from Plimer, referring to a time 100 million years ago when the dinosaurs roamed the planet: "The peak of 6 per cent carbon dioxide was at the time of a protracted greenhouse and maximum sea level. At this time, mean annual surface temperatures were 10C to 15C warmer than now."

The problem is, although his temperature estimate is about right, his CO2 estimate is about 50 times too high. CO2 levels were more like 0.12 per cent. At just three times present levels, this is a target we are on track to reach early next century.

Jump forward to 2009 and in his book Heaven and Earth Plimer seems to have quietly forgotten those geological lessons in stating: "Over geological time there is no observed relationship between global climate and atmospheric CO2."

Exactly which Plimer are we to believe?

Scientists are notoriously sceptical of the data collected by others. But ignoring a respected source is reprehensible. Cherry-picking only the data that fits is borderline. Deliberately misrepresenting data or making it up is just not on.

Here's an example. In a section from his new book, How To Get Expelled from School, as reprinted in The Weekend Australian recently, Plimer claims: "Antarctic ice core (Siple) shows that there were 330 parts per million of carbon dioxide in the air in 1900; Mauna Loa Hawaiian measurements in 1960 show that the air then had 260ppm carbon dioxide."

Plimer goes on to say: "Either the ice core data is wrong, the Hawaiian carbon dioxide measurements are wrong, or the atmospheric carbon dioxide content was decreasing during a period of industrialisation."

The implication is there must be something terribly wrong with the orthodox climate science and we are all being taken for a ride.

The problem is that the primary data sources explicitly state the Hawaiian Mauna Loa CO2 measurements for 1960 were in the range 313-320ppm, and that Siple air of age about 1900 has a CO2 content of 295ppm, with the 330ppm concentrations having an estimated air age of 1962-83, entirely in keeping with Mauna Loa.

Who has been taken for a ride?

Sadly, this is not an isolated case. Plimer has persistently claimed that volcanoes contribute much more CO2 to the Earth's atmosphere than do our own activities, blithely ignoring US Geological Survey reference data showing just the opposite - volcanoes emit CO2 at about 1 per cent of the rate of anthropogenic emissions.

Another common meme promoted by our contrarian geologists is that it is now a fact that the climate is cooling.

But may we ask by whose data is this a fact?

Certainly not NASA's, which showed last year was the hottest on record, followed by 2005, 2007, 2009 and 1998. In fact, NASA ranks nine of the hottest 10 years ever recorded between 2001 and last year. You'd reckon NASA had learned a few lessons about being careful with data.

Variations on decadal timescales are more relevant to climate trends than annual variations. NASA shows the average temperature over the decade 2000-09 was a full 0.2C higher than in the 1990s - the biggest decadal rise in temperature ever recorded.

With an increase of more than 0.5C over the past 40 years, the decadal trend is now warming faster than ever. It beggars belief that any serious scientist could assert the climate is cooling.

Our contrarian geologists also avoid the devil in the detail. NASA's data shows that winters are warming faster than the summers and the Arctic faster than the tropics. While the lower atmosphere is warming, the upper atmosphere is cooling.

These characteristics provide diagnostic fingerprints of the heat trapping expected for a greenhouse effect. They provide the smoking gun that points to rising greenhouse gas levels as

the cause, and rule out warming because of additional heat input from the sun.

Could that be why you won't hear our contrarian geologists refer to such data? Could their real agenda be in manufacturing doubt rather than the search for scientific truth?

If so, it wouldn't be a first, as Naomi Oreskes points out in her recent book Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming.

Now here's a point for those who, like Rinehart, think all geologists toe Plimer's contrarian line.

Oreskes is a noted geologist. Having published groundbreaking research on the origin of the giant South Australian Olympic Dam deposit, she has arguably contributed more to the understanding of Australian mineral wealth than has Plimer.

Now just imagine a meeting between Rinehart and Oreskes - that would be interesting!

<![CDATA[Welcome to CPA Brisbane Branch's New Site]]>Sat, 31 Dec 2011 02:34:15 GMThttp://cpabrisbane.weebly.com/our-blog/first-postWe in the CPA Brisbane branch are very excited about launching our website.
It features a mixture of information about our branch, what events are planned, news and opinion from a wide variety of sources, as well as promoting the ethos of the Party.

Our intention is to devote time to locating and presenting local, national and international news, opinion and information which reflects our ethos while providing you with a better informed world-view. All collated on this easy-to-navigate site.

We hope you enjoy reading the articles and watching the videos and come to be more informed about the Communist Party.
We hope to build the site in 2012 and welcome your contact for your views and suggestions.
