If you search hard enough you can find lots of this sort of bumpkin on the net. Almost entirely from unscientific sources that have a barrow to push.

If you still think climate change is not happening try reading literature from scientists that know what they are talking about instead.

 Hi alan, i am really concerned about future generations having to live with it. Scarey stuff.

This is the probably the most spine chilling report on climate change I've personally seen. Four scientists from Australia speak on the subject. It's not what they say about the science that troubles me. They're just confirming what scientists from all around the globe have been saying for 30 years.
It's when they start talking about how they personally feel, knowing what they know, about their own private plans for their own futures.

See if you can watch it and NOT be very concerned for your grand children. I wasn't able to.

All you people living in Darwin and Brisbane,time to get out.

The Professor said at the 8.51 mark if you live there you should seriously consider moving.

Come on these experts are gotta be taken seriously.

Climate change cant be solved by Australia with its small population when most of the world continues to polute,I suppose we can can throw millions of dollar at it and destroy our economy,but whats the point.

 I totally agree with your basic sentiment Ron. Whatever we do here in Australia won't change much unless the world as a whole chips in and does their bit. And, so far that hasn't happened, and if history and human nature are any indicators, it never will. Until it's too late.

Lowering of our C02 production hopefully may slow things down. Maybe.  Not stop it entirely. Renewable energy sources must and WILL become the norm someday. By necessity, 
As things get worse we are going to need more electric power to cope. If that is not from renewable sources, the downward spiral will continue.

That's why our efforts as a country today must be, in my opinion, to move towards renewables at a quicker pace. At the start of this cycle, as we are right now, totally reliant on renewables is not feasible. But start making it harder to burn coal and research and development dollars will be channeled into this end, and government infrastructure will have $ invested in it. Lile charging stations for electric cars. 

Will all this cost money? Yup. Lots of it. Especially at the start. Get used to it. Change is not optional.

I have read the original articles, but will admit, that I have been too busy to check all the facts, so will take them at face value

I also, (I suppose like many others), also take other environmental articles at face value

My understanding on the original articles, is that the authors are not denying that the temperature is increasing, but are calling it a natural climate change, and that it is all a hoax saying that we should stop carbon going into the atmosphere, as carbon is good

My understanding after reading other climate change articles, is that if we do not stop the temperature rise, caused by mankind, then we are in trouble

My personal opinion, (so I could be wrong), is that I have seen the temperature rise, in my lifetime
I would therefore prefer to do something to slow the temperature rise, than to do nothing

I also dismiss the argument, that as Australia does not put out as much pollution as other countries, then we do not need to do anything
To my way of thinking, doing nothing is the easy way out, and will accomplish nothing
Doing something is the hard way out, and may also accomplish nothing in the big scheme of things, but at least we can say that we tried

Gday...

Dunno wot all the angst is about ... since last weekend's election result, there is no climate change ... very few voted for it. 

Anyway - 

According to the U.S. Geological Survey (USGS), the worlds volcanoes, both on land and undersea, generate about 200 million tons of carbon dioxide (CO2) annually, while our automotive and industrial activities cause some 24 billion tons of CO2 emissions every year worldwide. Despite the arguments to the contrary, the facts speak for themselves: Greenhouse gas emissions from volcanoes comprise less than one percent of those generated by todays human endeavors.

Furthermore, some scientists believe that spectacular volcanic eruptions, like that of Mt. St. Helens in 1980 and Mt. Pinatubo in 1991, actually lead to short-term global cooling, not warming, as sulfur dioxide (SO2), ash and other particles in the air and stratosphere reflect some solar energy instead of letting it into Earths atmosphere. SO2, which converts to sulfuric acid aerosol when it hits the stratosphere, can linger there for as long as seven years and can exercise a cooling effect long after a volcanic eruption has taken place.

There are many scientific articles on that most trusted of resources, the internet, that dismiss the impact of 'climate change pollution' from volcano action.

Climate change may well exist but this tiny population in Australia doing it alone with some help from other countries are not going to achieve much alone ,its just a huge waste of taxpayers money we might be climate change heroes I suppose ,but unless most of the world joins in not much will be achieved just my opinion.

Thank you Delta. I am so relieved that someone is prepared to think about  climate change as an historical thing and that taxing/lowering carbon maybe is not actually the answer. to quote from the article.....

CO2 is the currency of life and the most important building block for all life on Earth. All life is carbon-based, including our own. Surely the carbon cycle and its central role in the creation of life should be taught to our children rather than the demonization of CO2, that carbon is a pollutant that threatens the continuation of life. We know for a fact that CO2 is essential for life and that it must be at a certain level in the atmosphere for the survival of plants, which are the primary food for all the other species alive today. Should we not encourage our citizens, students, teachers, politicians, scientists, and other leaders to celebrate CO2 as the giver of life that it is?

It is a proven fact that plants, including trees and all our food crops, are capable of growing much faster at higher levels of CO2 than present in the atmosphere today. Even at the todays concentration of 400 ppm plants are relatively starved for nutrition. The optimum level of CO2 for plant growth is about 5 times higher, 2000 ppm, yet the alarmists warn it is already too high. They must be challenged every day by every person who knows the truth in this matter. CO2 is the giver of life and we should celebrate CO2 rather than denigrate it as is the fashion today.

We are witnessing the Greening of the Earth as higher levels of CO2, due to human emissions from the use of fossil fuels, promote increased growth of plants around the world. This has been confirmed by scientists with CSIRO in Australia, in Germany, and in North America. Only half of the CO2 we are emitting from the use of fossil fuels is showing up in the atmosphere. The balance is going somewhere else and the best science says most of it is going into an increase in global plant biomass. And what could be wrong with that, as forests and agricultural crops become more productive?

All the CO2 in the atmosphere has been created by outgassing from the Earths core during massive volcanic eruptions. This was much more prevalent in the early history of the Earth when the core was hotter than it is today. During the past 150 million years there has not been enough addition of CO2 to the atmosphere to offset the gradual losses due to burial in sediments.

A few people have mentioned personal observations about how temperatures/seasons have changed in their lifetimes. It's reminded me of my own observation that I thought of. Take it as you will. Normal? or otherwise.

I was born on Dec 1st in Canada. The first day of winter. I have a very clear recollection of inviting a friend to my birthday party one year in the late 50's. He queried it because he had observed that my birthday had always coincided with the first snowfalls, and no snow had fallen yet. So, in the late 50's, snow was expected by Dec 1st.

In the late 70's, my daughter travelled to my hometown in December. She was looking forward to experiencing her first white Christmas. My brother was a little concerned because by that time a white Christmas was a 50/50 chance. (It did snow in time that year)

Very early in the new millenium, my nephew wrote that he was hoping it might snow in time for New Years eve that year. It was, at that time a 50/50 chance.

Last winter, the same nephew wrote that it had snowed for the first time that year on New Years eve. He remarked that it had been a long time since they'd had snow 'That early'

But when it does come, it is brutal. Almost as if it was making up for lost time.

All perfectly natural? Happens every billion years or so? You believe what you want to believe. Whatever gets you through the night.

All I am 100% convinced of is, the climate is most definitely changing. Rapidly. We won't stop it, but we best start down the path of coping with it. For every scientist writing that there is nothing to worry about, there are 100 stating the opposite.

No they used the grapes to make wine.
