Contribution to global warming by Australia. Australia has one of the highest per capita emissions of carbon dioxide in the world, with 0.3% of the world's population it produces 1.4% and rising(not the .08% the  finders forum dope "Inhere" claims!) of the world's greenhouse gases. Australia also has the highest per capita emissions in the OECD, with 26 tonnes of greenhouse gasses being emitted per person every year.
Australia's C02 emissions rise for the 4th year in a row.

 We can’t accurately predict solar activity, and a quiet solar cycle would have a small impact on Earth’s climate anyway

The  global cooling myth

So what are today’s conditions like? Changes in both the orbit and tilt of the Earth do indeed indicate that the Earth should be cooling. However, two reasons explain why an ice age is unlikely:
1. These two factors, orbit and tilt, are weak and are not acting within the same timescale – they are out of phase by about 10,000 years. This means that their combined effect would probably be too weak to trigger an ice age. You have to go back 430,000 years to find an interglacial with similar conditions, and this interglacial lasted about 30,000 years.
2. The warming effect from CO2 and other greenhouse gases is greater than the cooling effect expected from natural factors. Without human interference, the Earth’s orbit and tilt, a slight decline in solar output since the 1950s and volcanic activity would have led to global cooling. Yet global temperatures are definitely on the rise.
It can therefore be concluded that with CO2 concentrations set to continue to rise, a return to ice age conditions seems very unlikely. Instead, temperatures are increasing and this increase may come at a considerable cost with few or no benefits.


The Carbon Cycle and Ice Ages
Why are there Ice Ages? Will there be another one? In the following video with H.J. Schellenhuber this is explained:
Shifts in Earth’s climate due to orbital fluctuations are happening constantly, in predictable cycles. In the deep past these shifts caused the great ice ages. Today, changes in the carbon cycle are happening because of people. We are disrupting the carbon cycle by burning fossil fuels and clearing land. We were expecting the next ice age in the next 50,000 years due to this cycle. However, H.J. Schellenhuber calculates, using geophysics exponential equations he calls simple, that we have even thrown off the next ice age.
‘The will be no Ice age again. The human impact is so powerful already (that’s why they call it the Anthropocene), that we have suppressed the Quaternary planetary dynamics.’ – H.J. Schellenhuber
Even though it has become very popular for deniers to argue that the Earth is cooling and there is another ice age coming, this is not what objective, credible research tell us.

Actual Expert tells audience, We won't have an Ice Age again!

We show that the conditions for a new ice age will not be met in the near future, and that they will probably not be met for another
50,000 years.
As a result, even without the human emissions of CO2 since the Industrial Revolution, the Holocene would be an unusually
long interglacial. Given the extreme longevity of CO2 in the atmosphere,past and future anthropogenic CO2 emissions will have a significant
effect on the timing of the next ice age.
