Climate emissions targets. How are we tracking?

As New Zealand moves closer to landmark legislation to curb carbon emissions, a top Australian Earth System Scientist, Will Steffen, says more needs to be done to change the economic systems to drive long lasting change on a global level. He says New Zealand's biggest challenge is agriculture, but if it can crack how to get those emissions down that knowledge could be exported.   Will Steffen is an Emeritus Professor from the Australian National University.From 2004 to 2011 he served as science adviser to the Australian Government Department of Climate Change  and from 2011 to 2013 was a Climate Commissioner on the Australian Government's Climate Commission.

Predictions of sea level rise severely understated

A new study indicates previous estimates of the global impact of sea level rise have been grossly understated. The research, published in the journal Nature Communications and conducted by the non-profit news organisation Climate Central, suggests that three times as many people as previously thought could be at risk of annual flooding by 2050. That means that land that's home to 300 million people could now be at risk, rather than the 80 million people thought to be affected. Ben Strauss is one of the study's authors, and the CEO and Chief Scientist of Climate Central. He joins us to discuss the findings, and to explain why the current forecasts seem so far off the mark.

Fears gunshot injury may change leopard seal’s behaviour

A biologist observing a seal who may have been shot at the weekend says the injury could change the cheeky mammal's behaviour forever.   Resident leopard seal Owha is a familiar face around Auckland's Waitematā Harbour - known for sunbathing on pontoons and nipping the odd inflatable dinghy.   She was found bleeding from the head on Saturday from a suspected gunshot wound - an injury that might have permanent physical and behavioural effects.   RNZ reporter Anneke Smith has the story.
