## Every tonne of carbon matters
Climate scientists say every tonne of carbon dioxide adds to global warming, and every fraction of a degree increase matters to people and the environment.

## New tool predicts emission impacts
Climate scientists have released the Carbon Impacts Tracer, which uses peer-reviewed studies to estimate the impact of every megatonne of emissions on people and the environment.
## Hunter Valley coalmine expansion harms
Emissions from an Australian coalmine expansion of eight hundred nine million tonnes would cause one hundred seven deaths in Europe, put forty one thousand eight hundred additional people into extreme poverty, and cause other documented…
## Key takeaway

Climate scientists have released a tool that estimates the detailed impacts of fossil fuel emissions on food security, heat stress, and other harms.
