A new tool for the versatility of madness

Corporations claim their fossil fuel emissions are a drop in the ocean. But what if we could count the real cost?

The biggest coal project before authorities in New South Wales, the Hunter Valley Operations 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, or lead to more than 100 additional deaths from heatwaves in Europe to the end of this century.

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.

But the brilliance, the versatility of madness is akin to the resourcefulness of water seeping through, over and around a dike.
