Delving into deep time, Bill McGuire explains what is happening to our climate in the early decades of the twenty-first century and beyond.

Bill McGuire introduces his new book, published in May 2026, in which he delves into what geologists call ‘deep time’. Through this we can see both cause and effect: how the climate has changed before and what the outcomes were. We don’t need to make guesses, educated or otherwise, because all the evidence is laid out for us in the rocks and sediments, in the ice sheets, and in the remains of ancient life, making up the repository of information he uses to build and develop the core message of this book. This is how our planet remembers the past, and how it can shed light on what is happening to our climate in the early decades of the twenty-first century and beyond. The geological record is never wrong.
