Jim Skea, chair of the UN's Intergovernmental Panel on Climate Change, discusses the grim situation of rising emissions and missed targets in tackling climate change. They explore the challenges of limiting global temperature to 1.5 degrees, shifting emissions dynamics, climate finance, equity in climate policy, carbon capture, nuclear power, and balancing adaptation with emission reduction.
Global emissions are still rising despite efforts to combat climate change, indicating the urgency for collective action.
Exceeding the 1.5 degrees Celsius limit may lead to more extreme events and ecosystem threats, emphasizing the need for stringent mitigation measures.
Deep dives
Climate Change Urgency and Challenges
The podcast discusses the urgent need to address climate change as global emissions continue to rise despite efforts to combat it. Key indicators, like ocean temperatures, ice melt, and extreme weather events, point to the severity of the situation. The podcast emphasizes the necessity for collective action, burden sharing, and long-term strategic planning to mitigate the impacts of climate change.
Implications of Temperature Rise
The podcast explores the potential consequences of exceeding the 1.5 degrees Celsius temperature limit set by the Paris Agreement. Scientists predict that without significant emissions reduction, global warming may reach 2.5 to 3 degrees Celsius by the end of the century. The difference in impact between 1.5 and 2 degrees includes more extreme events, agricultural risks, and ecosystem threats, highlighting the importance of stringent mitigation measures.
Strategies and Challenges in Mitigating Climate Change
The discussion delves into mitigation strategies such as carbon capture and storage and the role of nuclear power in combating climate change. Despite the effectiveness of these measures, challenges remain in scaling them up due to economic and policy considerations. The podcast underscores the need for both emissions reduction and adaptation efforts to address the evolving climate crisis.
Stephen Sackur speaks to Professor Jim Skea, chair of the UN's Intergovernmental Panel on Climate Change. He is a key player collating the latest climate science and right now the situation looks grim; global emissions are still rising, so are temperatures and targets seem likely to be missed. Are humans bungling our chance to avert disaster?
