Under the Paris agreement, countries agreed to limit warming to below 2 degrees Celcius by the end of the century, with a nice-to-have target of 1.5 degrees Celsius. This latest IPCC report, warns that even the most optimistic 1.5 degree scenario will bring unprecedented changes to the planet, and be exceedingly difficult to achieve. So what now? 

Kathryn Ryan talks to Professor Mark Howden who has been involved in the planning and delivery of this report from the start as a Vice Chair of the IPCC Working Group 2 and as a Review Editor and the University of Canterbury's Associate Professor Bronwyn Hayward who is the only lead author from New Zealand.

09:25 Living off the land sustainably. Can it be done ?

Can New Zealand sustain its high living standards by growing grass? Does tourism have a sustainable future? Are we destroying our natural reputation upon which the country's two main earners are based, (dairying & tourism) and which account for half of our overseas earnings. A group of geographers and rural sociologists has teamed up to look at ways of creating a future economy from our biological resources without costing the earth. Their work is contained in a new book titled, 'The New Biological Economy' published by Auckland University Press. The University of Canterbury's Emeritus Professor of Geography, is Eric Pawson and Richard Le Heron is a Professor in the School of Environment at the University of Auckland.

11:45 When journalists become the story 

Media commentator Gavin Ellis says journalists play a risky game when they put themselves at the centre of a story but occasionally they produce a winner. Two stories at the weekend - on trauma and panic - hit home runs. Also, Auckland City has handed production of its residents' newsletter to the country's largest magazine publisher. The move will save money and improve quality but there are some lessons that the council must heed.
