COP26 is taking place in Glasgow, with the eyes of the world on the decisions being made, and climate change is finally getting the serious attention that scientists and campaigners have been demanding for a long time. But it’s only relatively recently that the public debate has really started to include the ocean, and a much deeper appreciation of the connection between our global ocean and Earth’s climate. This month, Helen Czerski explores a changing climate is affecting our ocean, and how a changing ocean is affecting our climate. And what policies would really make a difference for Earth’s vast blue heart? With thanks to Professor Margaret Leinen, Director of Scripps Institution of Oceanography, Professor Steve Simpson, from the University of Bristol, and Lord Deben, a former Environment Secretary described as the “Environment Secretary against which all others are judged”.
