#3-12 - Ocean Warming, Ocean Currents, and Climate Models - ft. Prof. Dr. Jochem Marotzke

In this episode, Bea talks to Prof. Dr. Jochem Marotzke, a managing director at the Max Planck Institute for Meteorology, about the role of the ocean in climate and climate change.

Jochem does fundamental research into human-caused climate change and researches the role that the ocean plays in climate and how it interacts with the atmosphere. Here, he explains how the ocean slows down the climate change by acting as a carbon sink and what consequences this has for the ocean.

Jochem describes the main reasons behind the global rise of sea level and talks about a handful of places where, locally, the fall in the sea level can be observed. He also talks about El Niño (a climate pattern of unusual warming of surface waters) and fluctuations in the global atmospheric temperature.

[A correction to what was said on El Nino and global temperature: The globally warmest year, 2016, followed the large El Nino of 2015/16. The second warmest year was 2020, not 2018, and there was no El Nino prior to that, which made 2020 all the more remarkable. Jochem said 2018 which should have been 2020.]

Bea and Jochem talk about climate change models and how they can be used to make statements and forecasts about the future. Jochem explains how we can discern the influence of humans on the temperature rise and how this discovery led to a Nobel Prise and the Paris Agreement.
