Sustainability In Your Ear welcomes again oceanographer and creator John Englander, who final visited with us in February 2023. John is the creator of two pivotal books on Sea Level Rise, High Tide on Main Street: Rising Sea Level and the Coming Coastal Crisis, which explores the science behind rising seas and its far-reaching impacts on society, and Moving to Higher Ground: Rising Sea Level and the Path Forward, which gives a complete have a look at how people, companies, and governments can adapt to this unavoidable actuality.

John additionally shared current warnings concerning the collapse of the Atlantic Meridional Overturning Circulation (AMOC), which drives circulation of seawater globally.
