US climate bill success masks scale of warming challenge

Many are hailing a landmark US bill approved by the US Senate as a game changer for American and global efforts to tackle the root causes of rising temperatures.

But how will the Inflation Reduction Act (IRA) work and what will it achieve in terms of reining in global temperatures?

..."Although the US bill provides $370bn in climate spending, those of us in the Global South are wondering why the US and other rich countries have failed to keep their own promise to collectively provide $100bn of climate finance to poor and vulnerable countries by 2020," said Mohamed Adow, the director of the Power Shift Africa think tank, who welcomed the progress the bill represents.
