Carbon Impacts Tracer can be used to estimate climate impact from emissions across eight different factors, including lost food production
The biggest coal project before authorities in New South Wales, the HVO mine, will emit the equivalent of about 809m tonnes of climate-warming carbon dioxide if it wins approval.
That number, for most people, will carry little meaning, as might the calculation that adding that amount of greenhouse gas to the atmosphere will cause an extra 0.00036C of global heating.
But what if the public was instead told that that amount of carbon dioxide would expose almost half a million people to unprecedented heat, or kill nearly 15 million coral colonies on the Great Barrier Reef every time it bleaches?
All those statistics come from a new tool that translates the emissions from burning fossil fuels into estimated real-world climate effects taken from peer-reviewed climate studies.
“Small numbers in global warming can mean catastrophic impacts,” says prof Sarah Perkins-Kirkpatrick, a climate scientist at the Australian National University who is part of a team launching the Carbon Impacts Tracer.
