This week the US Senate passed the biggest package of climate change measures in American history. The Inflation Reduction Act, which is expected to be passed by the House and signed into law by President Biden, includes $369bn in funding for climate and clean energy policies. Its backers hope it will reduce the country’s greenhouse gas emissions by 40% by 2030 compared to 2005 levels. But the bill had no Republican support in the Senate, raising doubts about just how long-lasting its impacts might be. So, is the US getting serious about climate change? And why do the political divisions about what to do about it run so deep?
