This new tool, the Carbon Impacts Tracer, which translates carbon emissions into real-world climate impacts like heat exposure and coral bleaching, looks super useful. ➡️ carbonimpactstracer.com

New tool directly links carbon emissions to amount of environmental and economic damage caused
Carbon Impacts Tracer can be used to estimate climate impact from emissions across eight different factors, including lost food production
