Deep sea coral to reveal a history of climate change (Podcast 20 Jan 2009)
An American research vessel, the RV Thomas G. Thompson, has arrived back in Hobart after an expedition to collect deep-sea corals south of Tasmania. An un-manned deep-diving ‘Remotely Operated Vehicle’ (ROV) with a capacity to go as deep as 6000 metres was used to collect samples and data, and photograph and video areas of the ocean floor. (9:17)
Today's farmers meeting tomorrow's climate challenges (Podcast 03 Jul 2008)

In this podcast, Dr Mark Howden from CSIRO’s Climate Adaptation Flagship, explains how farmers are dealing with challenges such as lower rainfall and irrigation allocations. (4:51)
Understanding tropical cyclones
Tropical cyclones threaten northern Australia every year. Recent Australian flooding and cyclonic events can be largely explained by a strong La Niña. However, sea surface temperatures off the northern Australian coast in 2011 were at or near record levels. The extremely high sea surface temperatures are part of a significant warming of the oceans that has been observed in the past 50 years. These pages provide some information about the causes, occurrence and impacts of tropical cyclones.
