Solutions to Climate Change

Crescent Dunes Solar Thermal Power Station: Nevada USA

Globally, we must reduce the level of carbon dioxide in our atmosphere, and the levels of other greenhouse gasses like methane.  We need to do this with the greatest urgency. The technology is ready. We can do this. There are solutions.


Australia can become a renewable energy superpower.

The transition to a zero-carbon economy is a fantastic opportunity for Australia – mainly because we have exceptional renewable energy potential. We can become a renewable energy superpower by responding fully and rapidly to the climate emergency. If we act now, we can have lower electricity prices, reliable electricity, reduced emissions, more jobs, and a more prosperous and secure future. … more


Scientific consensus on climate change

Hazelwood coal-fired power station: Victoria Australia

We do need to reduce emissions because we are experiencing “human-caused climate change”. The evidence is overwhelming. The scientific consensus is that humans have burned vast amounts of fossil fuel and forest, leading to:
. sky-rocketing carbon dioxide levels in the atmosphere,
. global warming, and
. climate change.


Evidence of human-caused climate change

Here is some evidence, the movement of key indicators like carbon dioxide levels. See what has happened.

Graph: Carbon dioxide levels over past 400,000 years. Since 1950 levels have rocketed.

The orange line shows the movement of carbon dioxide levels in the atmosphere over the last 400,000 years. The level has sky-rocketed during our industrial age. … See more Evidence.


Convergence: The Basis for Scientific Confidence

Scientists are certain that we are experiencing human-caused climate change because many independent lines of research converge on this conclusion. … See more on Convergence.


The dangers posed by climate change.

Head in the sand. Blind to the ocean.

The dangers of climate change are profound.


The critical danger: Amplifying feedbacks

The critical danger is that the current global warming could kick off a vicious cycle of escalating temperature, with warming causing more warming, and this warming causing more warming, and so on. … See more on Self-amplifying feedback cycles.
