Our own Hannah Ritchie has a new book about tackling climate change coming out next month!

Called “Clearing the Air”, it covers everything from renewable energy and nuclear power to electric vehicles, heat pumps, minerals, carbon capture, and geoengineering.

It will be released on 18th September in the UK (stay tuned for when it will be released in other regions!).
