The Australian Academy of Science has joined Commonwealth of Nations science leaders from around the globe to call on the Commonwealth Heads of Government to use the best available science to guide action on climate change.

The call is part of a Consensus Statement on Climate Change launched by 22 national academies and societies of science from around the Commonwealth, ahead of next month’s CHOGM summit in the United Kingdom.

The consensus statement, which represents the consensus views of tens of thousands of scientists, marks the first time Commonwealth nations have come together to urge their Governments to take further action to achieve net-zero greenhouse gases emissions during the second half of the 21st Century. 

Secretary of Science Policy at The Australian Academy of Science, Professor David Day, said the long-term goal of keeping the increase in average global temperature to well below 2 °C above pre-industrial levels, agreed to by 160 parties in the 2015 Paris Agreement, was only the first step in a long journey.

“Even if all the country commitments from the Paris Agreement are met, the best interpretation of the latest data shows that by the end of the century the global climate is likely to be 3°C above pre-industrial levels.

“This is substantially higher than the Paris target to limit warming to less than 2°C, and would have profound impacts affecting billions of people throughout the world,” Professor Day said.

Sustainability is one of the key themes to be discussed by Commonwealth leaders at the 2018 CHOGM summit, with a focus on the resilience of developing and vulnerable countries to climate change.

“Recognising different capacities, challenges and priorities, the approaches of each nation will not be the same. But, they must be informed by the best available scientific evidence, monitoring and evaluation,” Professor Day said.

“The Academy stands ready to assist the Australian Government, and indeed broader Commonwealth efforts, by continuing to provide sound scientific advice on issues relating to climate change.”
