Arctic permafrost is thawing four times faster than global average, releasing 200 million tons of carbon dioxide.
The episode "2024 Global Climate Change Review" begins with host Lin Erxiang introducing Chairman Jian Youxin of the Taiwan Sustainable Energy Research Foundation. They open by noting 2024 was the hottest year on record according to European climate agencies. The discussion first focuses on the Arctic, where warming is four times the global average, causing permafrost to thaw and release approximately 200 million tons of carbon dioxide—a dangerous feedback loop. Melting ice also reduces Earth's albedo, as dark ocean water absorbs more solar energy than reflective ice. The conversation shifts to extreme weather events worldwide. In East Asia, temperatures exceeded 45°C, causing heatwave deaths and water shortages. Canadian wildfires in 2024 emitted about 14 billion tons of carbon, a figure starkly contrasted with Taiwan's annual industrial emissions of 2.8 billion tons. The Amazon rainforest lost 6,288 square kilometers to fires from July 2023 to July 2024, largely due to illegal deforestation and land clearing. The hosts note Brazil's President Lula faces challenges in controlling this. Extreme rainfall caused record floods in California and the Philippines experienced six consecutive typhoons, including one in December—an abnormal pattern. The episode then transitions to positive developments in 2024. Solar energy installation reached record levels, with significant growth in China, India, Germany, and new efforts in Saudi Arabia and Dubai. Electric vehicles became mainstream, highlighted by Norway where 25% of cars are electric and 174 models are available; the country plans to ban new fossil fuel vehicles. The US increased charging stations by 35% in the first nine months of 2024, and Australia offered low-interest loans for EV purchases. China's competitive EV industry is noted as pressuring traditional automakers like Ford and Apple. Finally, the UK's early closure of a coal-fired power plant in September 2024 is discussed as a symbolic move, with 46 countries having phase-out timelines. The episode concludes by acknowledging the difficulties in Asia where coal plants are newer, but expressing hope that global efforts will improve the planet's habitability.
