Those who have done the least to cause climate change are those hit hardest by the impacts. So, how can we solve climate injustice? On this week's episode of Sky News ClimateCast, hosts Anna Jones and Katerina Vittozzi hear from Former President of Ireland and Chair of the Elders, Mary Robinson. They examine the five layers of climate injustice and discuss how the world can work together to help those most at risk. From tackling inaction, to the importance of diversity, to the key ingredients of a successful COP - Mary Robinson has (some of) the answers. Plus, climate reporter Victoria Seabrook runs through this week's climate headlines: from flash floods in the US to a Sky News Exclusive involving biomass production.
