Imagination is key in science _ John Church from National Science Week.  We caught up with Dr Church at the CSIRO Greenhouse 2011 Forum. He has been studying climate change effects on the oceans since the 1970s.

QUOTE:

"I do think that climate change is a really serious issue that we are not adequately grappling with but, on the other hand, there are many things we can do to improve that future.

"I think we can meet the challenge of reducing our emissions and living in a more sustainable way, as long as we choose to do that."
