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.

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”.
