Ted Scambos’s Antarctic Adventures: A Tale of Climate Science and Discovery
open.spotify.com
Glaciologist Ted Scambos discusses the study of glaciers and their response to climate change. He explains that glaciers are massive ice formations that flow under their own weight and can be found in areas with national parks or world heritage site designations. Changes in glaciers can be influenced by global climate change and local factors. The flow of ice in a downhill direction drives the glacier, and warmer ocean waters reaching the underside of the ice are causing glaciers to speed up and slide further into the water. The collapse of the Thwaites Glacier in West Antarctica could raise sea levels by six to eight feet, posing a significant threat to coastal cities. The melting of glaciers in Antarctica also affects sea levels globally, redistributing mass and causing sea levels to drop near Antarctica but rise in other places. The impact of melting ice in Antarctica extends to ocean currents and the exchange of water between the surface and deep ocean. Melting ice also has implications for the health of the ocean and fisheries. Scambos criticizes politicians who deny climate change and emphasizes the need for action to address global warming. He discusses the importance of Landsat in polar science and its impact on understanding Antarctica. Satellite imagery allows scientists to explore and analyze large areas of Antarctica, providing valuable insights into changes in ice flow, temperature, and other characteristics. Scambos and his team use various instruments and innovative approaches to study the interaction between warm water and glaciers. They also collect data from seals to study Antarctic conditions. Scambos encourages people to visit Antarctica and witness the changes, while ensuring measures are in place to protect the environment. He emphasizes the need for society to take action on climate change, including reducing emissions and transitioning to renewable energy sources. Scambos believes that nuclear power can be a safe and viable solution, but renewable energy should be prioritized. He envisions a future where individuals, companies, and governments contribute to the renewable energy sector. Scambos emphasizes the importance of long-term thinking and action in addressing climate change and expresses his optimism and commitment to being part of the solution.
