Climate is changing, I'm not sure that can be denied by anyone. The cause of the climate change is still up for debate I reckon.
Is it purely man made changes or are we just in another upward cycle that's been happening for 100s or tousands of years ?

If someone can provide another hypothesis then I'm all ears, solar flares were all the rage a few years ago, now it seems to be a case of the 'plateau' which is complete garbage. The problem with denialists is that they ignore the science in favour of political conspiracy theories. I'm yet to hear one person refute the greenhouse effect, a pretty basic task if one was serious about tackling the science. As for the climate changing, sure it's variable, but one can also have multiple factors at play. Humans are speeding up the process, along with pumping greenhouse gases into the atmosphere, we're also deforesting at alarming rate. If there's anything up for debate it's determining the key causes and directly addressing these as an immediate priority. Those content with the do nothing approach are gambling with the nations future, Australia stands to lose more than most (not to mention the enormous economic benefits with the inevitable switch to renewables).
This would indicate that as far as a long term trends are concerned, the world isd not at it's hottest.
I dont doubt there is an effect from human generated causes, but you can't exclude the natural cycles either. How much is one and how much is another is the though question. But regardless, if we are in a position to help slow the warming, then we should, whether it's human generated or not.

I certainly don't doubt natural causes, but I also see anthropogenic climate change as an overlay on the natural cycle. The fact that the poles are breaking up should be reason for concern. Given the earth now has 7 billion inhabitants we are certainly entering a period of great uncertainty, it almost seems a forgone conclusion that the dogfight over resources will see many more losers than winners. The 21st century has the potential to get very ugly indeed.
I just got a copy of the Age from 323,000BC. ... There is an article that Says that mammoth and triceratops farting is heating the earth to unsustainable levels.

I don't know the context of the graph Baloo but a video I posted on the global warming thread a couple of times (because Peaka - or someone - kept saying he'd get back to me after he'd watched it, I'm still waiting) goes into the natural trend that lines up with Earth's cosmic dance with the sun. The difference is that the shift to warming usually precedes the increase in atmospheric CO2 which then ramps up until it overtakes the cosmic factors and becomes the driving force in the warming. The present epoch is first time that the CO2 increase has preceded the warming. That seems to suggest this time is different, according to the video.

That graph should be very concerning to everyone Baloo. It shows 11 degrees of temperature change between the height of the last ice age and the very warmest of the interglacial. That temperature difference resulted in ice sheets kilometres thick over Europe and North America. It represents some of the most extreme climate change for millions of years. Projected climate change for current global warming is between 1.1 and 6 degrees - if an average is taken, then a third as much as was needed to create such massive changes in the environment.
Also, the glacial/interglacial fluctuations in that graph match solar insolation due to orbital variability. The current climate changes can't be explained by known non-human origins.

You lost me at "That graph..."
I don't know anywhere near enough of the science to make an educated guess at where we are or where we are going. I just think that there is some cyclical activity in the temperature changes and not just man made. Though tghe mad man changes could be accelerating things. Dunno.
But I'm all for doing what we can to reduce emmissions, not just for the climate but for the general state of the environment. I wish Abbott would make a Captain's Call and give every Australian citizen as Tesla S
Baloo said:
No doubt there are natural influences on climate change Baloo, but that graph isn't a good example. As I said, it shows cyclical changes that have been known about for years and have been excluded as possible causes for current changes. When denialists (not including you there by any means) throw such examples around it's just muddying the waters.

I saw a few Teslas when I was in Norway. I'll have one of the free ones for sure. I think framing the debate as left verus right or debating science is all wrong. We have the technology and the imperative to get on board with a revolution in energy and sustainability that will benefit all and create new jobs and products that haven't been dreamed of. The environmental payoff need only be an afterthought. Mind-numbingly stupid arguments between non-experts about very complex science is about stalling and political grandstanding. We need to shift the debate.
I'll only have the free Tesla when it's recharged by power from renewable sources.
Until then, it's just shifting polution from one region to another.

Indeed. How about we shift the debate to question why the government has anything to do with the power industry whatsoever?KnightersRevenge said:

Funny that's how I'd describe the current system. Let's assume that's true. Why don't you then advocate for full government control over the power industry?KnightersRevenge said:
