Your questions answered: Geo-engineering; keeping houses cool; the climate powers of sharks

Presenter Graihagh Jackson and her regular panel take Climate
Questions from listeners. BBC Climate Editor Justin Rowlatt, Prof
Tamsin Edwards of King's College London, and Dr Akshat Rathi,
senior climate reporter for Bloomberg News, discuss ideas for
geo-engineering the atmosphere, the links between climate change
and shipping, and which animals do the best job of helping us
store carbon.


Plus, Graihagh visits a Climate Question listener to investigate
his idea of using yoghurt to keep our homes cool in heatwaves!
