Declining forests of Giant Kelp

Imagine diving between giant kelp that reach more than 30 metres from the bottom of the ocean to the surface. The east coast of Tasmania is one of the few places in the world where these underwater forests exist. But how much longer will they survive? Watch this clip to find out why these magnificent ecosystems are disappearing ...

Carbon capture and storage

Is carbon capture and storage (CCS) the solution to climate change? CCS technology captures carbon dioxide from the flue gases of coal burning power plants and takes it to long-term storage. The coal industry has high hopes that pumping the liquefied gas into underground reservoirs, or geo-sequestration, will provide safe ...
