Climate change


Evidence of human-caused climate change

View the movement of key characteristics of our planet, like carbon dioxide levels, so you can see what has happened, and get an idea about what might happen next.

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

Viewing the movement of carbon dioxide levels in the atmosphere over the last 400,000 years shows how the level has gone up like a rocket since 1950. … See more Evidence.


Scientific consensus on climate change

Hazelwood coal-fired power station: Victoria Australia

The evidence supports the firm conclusion that we are experiencing “human-caused climate change”. That is, humans have burned vast amounts of fossil fuel and forest, leading to:
. the rocketing carbon dioxide levels,
. global warming, and
. climate change.


Convergence: The Basis for Scientific Confidence

Image of convergence: A red arrow and five blue arrows meet point to point

Scientific confidence in a conclusion emerges when independent lines of research converge on the same conclusion. 

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.


Solutions to Climate Change

Crescent Dunes Solar Thermal Power Station: Nevada USA

Australia could become a renewable energy superpower.

Australia can grasp a prosperous and secure future by responding fully to the climate emergency. We can become a renewable energy superpower: (1) Rapidly taking up renewable energy, (2) Exporting renewable energy, not coal and gas, and (3) Drawing in new energy-intensive industries. … See mor on Solutions
