Book review:Unsettled: what climate science tells us, what it doesn’t, and why it matters by Steve Koonin

In Unsettled: What Climate Science Tells Us, What It Doesn’t, and Why It Matters, Steve Koonin sets out his scepticism about the science of climate change, arguing that increasing global temperatures could be down to natural variability rather than human activities. Bob Ward finds that the book is not a robust guide to the subject and is based on a number of inaccurate and misleading claims, flawed studies, and cherrypicked information.
