We speak with Harjeet Singh, senior adviser with the Climate Action Network, who is at the U.N. climate summit in Glasgow. Activists like Singh are pressuring world leaders to join the Fossil Fuel Non-Proliferation Treaty, which would supplement the Paris Agreement by directly targeting the fossil fuel industry and outlining clear actions that every country could take to drastically decrease carbon emissions.

We speak to Farhana Yamin, one of the most prominent climate lawyers in Britain, who has been deeply involved in international climate negotiations for decades, including the landmark 2015 Paris Agreement, and has also engaged in direct action to effect change. Yamin is currently working with the Climate Vulnerable Forum, a group that represents 48 of the countries most threatened by the climate crisis, at the U.N. climate summit in Glasgow.

We speak to Mohamed Nasheed, the former president of the low-lying island nation of the Maldives, at the U.N. climate summit in Glasgow. Nasheed is one of the world’s leading climate advocates, who once held a cabinet meeting underwater to bring attention to the threat of global warming, pledged to make the Maldives the first carbon-neutral country and installed solar panels on the roof of his presidential residence.

We speak to Mitzi Tan, a climate activist based in the Philippines, who will join Greta Thunberg of Sweden and Vanessa Nakate of Uganda in speaking at a major march and rally in Glasgow on Saturday. Among their demands are reparations from the Global North to the Global South to help rebuild the lives of those most impacted by the climate crisis.

As we cover the fight against Big Coal with climate activists attending the U.N. climate summit in Glasgow, Scotland, we look at the U.S. territory of Puerto Rico, which has experienced some of the most extreme weather over the last two decades. Hurricane Maria destroyed the island’s electrical grid four years ago and left residents in the dark for months.
