The rapidly shrinking window of opportunity for the US to pass significant climate legislation will have mortal, as well as political, stakes. Millions of lives around the world will be saved, or lost, depending on whether America manages to propel itself towards a future without planet-heating emissions.
For the first time, researchers have calculated exactly how many people the US could save by acting on the climate crisis. A total of 7.4 million lives around the world will be saved over this century if the US manages to cut its emissions to net zero by 2050, according to the analysis.
