Gina McCarthy will leave her post as top domestic climate adviser to President Joe Biden on 16 September amid intensifying moves by cabinet departments to ramp-up action to spur the US transition to cleaner energy.

Ali Zaidi, her deputy, will take over as National Climate Advisor from the influential McCarthy, whose office helped draft provisions of a new climate law that includes $369bn in related spending and clean energy-related tax credits, the biggest such investment in US history.
