The Impacts of Oceanic Heat Waves on the Marine Ecosystem

In this ClimateGenn episode I am speaking with Dr Jennifer Francis, a senior scientist at the Woods Hole Climate Research Center, in the US. 2023 has already seen record breaking temperatures in the atmosphere, land and oceans, with horrific impacts to human life, communities and ecology.

Here we focus on three factors in the climate system that drive these extremes and are still set to break more records, creating a great deal more destruction this year. We focus on the forming El Niño climate phenomenon, as well as ocean heatwaves, impacting the Atlantic and the North Pacific. 

Finally, we also discuss the role of the thinning sea ice that is accelerating change in the Arctic region. These changes drive up heat in the Arctic faster, impacting ecosystems and altering the jet stream, these latter impacts being the focus of Dr Francis’s research for over a decade.
