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.","\u002Fapi\u002Fmedia\u002Fposts\u002Fnew-tool-directly-links-carbon-emissions-to-amount-of-enviro-3ef47177\u002F1.webp",{"local":16},{"headline":19,"body":20,"imageUrl":21,"images":22},"“Small numbers in global warming can mean catastrophic","“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.","\u002Fapi\u002Fmedia\u002Fposts\u002Fnew-tool-directly-links-carbon-emissions-to-amount-of-enviro-3ef47177\u002F2.webp",{"local":21},{"headline":24,"body":25,"imageUrl":26,"images":27},"The NSW Independent Planning Commission is expected to","The NSW Independent Planning Commission is expected to make a decision this week about the future of the HVO mine, with the joint owners Yancoal and Glencore hoping to keep digging at the Hunter Valley site until 2045.","\u002Fapi\u002Fmedia\u002Fposts\u002Fnew-tool-directly-links-carbon-emissions-to-amount-of-enviro-3ef47177\u002F3.webp",{"local":26},{"headline":29,"body":30,"imageUrl":31,"images":32},"Plugging the project’s expected emissions into the tracer","Plugging the project’s expected emissions into the tracer suggests, for example, the extra heat trapped in the atmosphere by its emissions will reduce crop production every year by an amount that is the equivalent to the minimum dietary requirements of 276,129 people.","\u002Fapi\u002Fmedia\u002Fposts\u002Fnew-tool-directly-links-carbon-emissions-to-amount-of-enviro-3ef47177\u002F4.webp",{"local":31},{"headline":34,"body":35,"imageUrl":36,"images":37},"The tool can be used to estimate the","The tool can be used to estimate the impact of carbon dioxide emissions from any project, company or state – or for any known amount of emissions – across eight different factors including the loss of labour hours due to excess heat, the loss of glaciers, the death of corals or lost food production.","\u002Fapi\u002Fmedia\u002Fposts\u002Fnew-tool-directly-links-carbon-emissions-to-amount-of-enviro-3ef47177\u002F5.webp",{"local":36},{"headline":39,"body":40,"imageUrl":41,"images":42},"Central to the tool is a metric known","Central to the tool is a metric known as Transient Climate Response to CO₂ Emissions (TCRE) – an established calculation that every billion tonnes of CO2 causes about 0.45C of global heating.","\u002Fapi\u002Fmedia\u002Fposts\u002Fnew-tool-directly-links-carbon-emissions-to-amount-of-enviro-3ef47177\u002F6.webp",{"local":41},{"headline":44,"body":45,"imageUrl":46,"images":47},"Once an amount of CO2 is known –","Once an amount of CO2 is known – such as from a major fossil project – it’s contribution to global heating can be calculated and, from there, says Perkins-Kirkpatrick, measured against already published studies. “Every tonne of CO2 maters and we’ve known this for decades,” she said.","\u002Fapi\u002Fmedia\u002Fposts\u002Fnew-tool-directly-links-carbon-emissions-to-amount-of-enviro-3ef47177\u002F7.webp",{"local":46},{"headline":49,"body":50,"imageUrl":51,"images":52},"“To pinpoint what this means with a high","“To pinpoint what this means with a high degree of confidence has taken us a long time.
