58 countries have submitted their climate targets ahead of international talks in Paris. We know the numbers, but not all efforts to combat climate change are equal.
Tom Switzer and Naomi Klein, speaking on Q&A.
US Studies Centre research associate Tom Switzer said on Q&A that US carbon emissions had levelled off because of coal seam gas, but activist Naomi Klein said it was due to the economic downturn. What does the research say?
