Doug Allan discusses how climate change is affecting the oceans and their most charismatic inhabitants. Doug has also been involved recently in projects that reflect his deep concern about climate change and conservation, particularly how these issues impact on marine mammals. With over 40 years’ experience of the poles, he has witnessed first-hand the effects of the change in sea ice cover on the populations of sea mammals north and south. For the US based Living Oceans Foundation, he’s filmed scientists charting the threats to some of the world’s most remote coral reefs. What he’s seen reinforces his determination and commitment to raise awareness of this global issue through his speaking engagements.
