Australia must act immediately on climate change or risk social, economic and environmental disaster, the Climate Commission’s first major report says. Here’s your quick and easy guide to the rest of the good news.

The report, The Critical Decade, reviews the latest climate science and says it unambiguously shows the climate is changing, and humans are “almost surely” the cause. It slams the sceptics, saying there is no debate within the scientific community on the reality of climate change.
It argues a carbon pricing mechanism is necessary to curb emissions and says we must act urgently or “we will struggle to maintain our present way of life”.
Main points:
- The global climate is changing and humanity is almost surely the primary cause. The risks have never been clearer and the case for action has never been more urgent.
- The atmosphere is warming, the ocean is warming, ice is being lost from glaciers and ice caps and sea levels are rising. The biological world is changing in response to a warming world. Global surface temperature is rising fast; the last decade was the hottest on record.
- With less than 1 degree of warming globally the impacts are already being felt in Australia; there are more heatwaves and bushfires, the sea is rising and the Great Barrier Reef has suffered an increase in bleaching events.
- Human activities – the burning of fossil fuels and deforestation – are triggering the changes we are witnessing in the global climate.
- This is the critical decade. Decisions we make from now to 2020 will determine the severity of climate change our children and grandchildren experience. To minimise this risk, we must decarbonise our economy and move to clean energy sources by 2050.
What the people say:
Report author Professor Will Steffen, executive director of the Australian National University’s Climate Change Institute, told the Herald Sun that the Coalition’s plan to offset emissions wouldn’t do enough, and that Australia also needs to curb emissions:
We have to reduce fossil fuel use and while locking away CO2 can be a good thing, it can’t work alone. It must be accompanied by fossil fuel use and emissions reductions.
Prof Ove Hoegh-Guldberg, the Director of the Global Change Institute, University of Queensland, said the report should compel politicians into action:
It is vitally important that responsible governments everywhere face up to the urgency of the situation that we face with respect to climate change, and to act on the recommendations of their experts.
Commission head Professor Tim Flannery told the ABC that “uninformed opinion” was to blame for ongoing scepticism about climate change:
You get all sorts of people posing as having some expertise in climate science, whether they be taxi drivers … or people in the media who don’t have the expertise. That is clouding the waters a little bit and slowing things down.
Professor David Karoly from the Science Advisory Panel said the report contained the latest science, was independently reviewed, and its conclusions matched those reached by all major scientific academies.
Professor Matthew England from the Science Advisory Panel said the message was clear:
Climate change is accelerating and it is impacting Australia significantly. The window for limiting future and costly climate change is rapidly closing. This should be a wake up call for global and national action on greenhouse gas emissions.
Parliament will host a multi-partisan forum on climate change tomorrow.
