We have most of the technology we need to combat the climate crisis – and most people want to see more action.

But after three decades of climate COPs, our global emissions are worse than ever. And we are accelerating into a polycrisis of climate, food security, biodiversity, pollution, inequality, and more. 

What, exactly, has been holding us back? What will it take for us to do better? In the search for answers that have been so elusive to date, Mike Berners-Lee looks at the challenge from new angles. He stands further back to gain perspective; he digs deeper under the surface to see the root causes; he joins up every element of the challenge; and he learns lessons from our failures of the past.  His investigations uncover the single point of greatest leverage for those seeking the systemic change we so desperately need. A Climate of Truth spells out why, if humanity is to thrive in the decades ahead, the most critical step is to raise standards of honesty in our politics, our media, and our businesses. 

Despite recent lurches in the wrong direction, not only is this possible, but each of us can have radically more impact on the issues we care about most, by turning our attention to this simple principle.

Anyone asking, ‘How can I have impact when everything so far has seemed so futile?’ will find inspiration in this practical and essential book.
