In this never-dull, easy-to-understand guide, Dr Karl explores the science of climate change, and how we can fix it. (We can!) How do Greenhouse Gas molecules shimmy and shake to trap 400,000 Hiroshima atom bombs' worth of the Sun's heat each day? Who did the early research in Climate Change and then spent billions trying to cover it up? What's the Hockey Stick Graph and why is it so important? How did Climate Change tip the Earth off its axis? Why was Sydney the hottest place on Earth on 4 January 2020? How can we move to zero and even negative emissions? How can kelp help? When it comes to long-haul transport, why is hydrogen the way to go? AND MUCH MORE!
