The Gulf Stream shapes weather from Miami to Manchester—but is it really weakening?

In this SciCafe, Christopher Piecuch, associate scientist in the physical oceanography department of Woods Hole Oceanographic Institution, dives into the science behind ocean circulation, sea level rise, and climate whiplash.  

Learn how researchers use decades of complex and costly observations to understand the Atlantic Ocean’s overturning circulation and how recent corrections to a key dataset have upended what we thought we knew. From the Florida Straits to the North Atlantic, Piecuch explains what’s actually happening beneath the waves, what’s still unknown, and why the process of scientific revision is essential for understanding a changing climate.
