New tool links coal mine emissions to specific climate damage

A new climate impact calculator has been used to estimate the real-world effects of carbon emissions from the HVO coal mine in New South Wales.

Emissions translate to human and reef loss

The tool calculates that the project's output would expose nearly half a million people to unprecedented heat. It also estimates the death of almost 15 million coral colonies on the Great Barrier Reef during each bleaching event.

Food production faces significant annual reduction

Analysis suggests the trapped heat would reduce crop production by an amount equivalent to the dietary needs of 276,129 people every year. The Australian Independent Planning Commission is expected to decide on the mine's future this week.

Scientists warn small numbers mean big impacts

Professor Sarah Perkins-Kirkpatrick from the Australian National University states that small global warming figures can represent catastrophic local consequences. The joint owners Yancoal and Glencore hope to continue operations at the Hunter Valley site until 2045.
