    Global emissions hit record high after three-year pause

    Global emissions hit record high after three-year pause

    For three years, the world's emissions of greenhouses gases from fossil fuels and industry had plateaued. But the release of new figures from the Global Carbon Project suggests that pause may be over.

    The Global Carbon Project's Dr Pep Canadell gives us the numbers and explains why emissions are on the up again. Climate policy expert Professor Frank Jotzo asks what that means for policies around the world.

    How a 1969 snorkel trip led to a shocking discovery about the future for the world's coral reefs.

    How a 1969 snorkel trip led to a shocking discovery about the future for the world's coral reefs.

    Marine biologist Professor Ove Hoegh-Guldberg "almost fell off the chair" when he realised how vulnerable the world's coral reefs would be to climate change. But after being attacked as an "alarmist", it turns out he may have been too conservative.

John Cook (Skeptical Science) ,

Great first episode

Really enjoyed the first episode. The host Graham is enjoyable to listen to (not just because of the accent), is incisive and has deep knowledge of both the science and sociology of climate change. And two great interviews. Sarah Kirkpatrick has that (unfortunately rare) ability to talk as a climate scientist and as a real human being at the same time. And Riley Dunlap is a legend in the field of researching climate science denial. Look forward to future episodes...
