Increase in massive marine heat wave events since 2003 triggered a widespread ecological reorganization in the North Atlantic

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Major heat wave in the North Atlantic had widespread and lasting impacts on marine life” by Werner et al. (2026). Scientific analysis reveals that a massive marine heat wave beginning in 2003 triggered an abrupt and extensive ecological reorganization across the North Atlantic. Researchers utilized decades of...

A note on the potential AMOC collapse for nonexperts

As the Earth warms due to anthropogenic climate change, sea- and land-based ice melts, adding buoyant freshwater to the surface of the high-latitude North Atlantic and thus decreasing salinity. This makes the surface water lighter reducing the sinking of the surface water and thus the AMOC. However, the amount of added freshwater is not enough... Continue Reading →

Human-induced weakening of the AMOC averted for now

The current state-of-the-art climate models suggest that the human-induced weakening of the Atlantic Meridional Overturning Circulation (AMOC) has already begun since the mid-1980s. However, continuous direct observational records during the past two decades have shown no clear sign of a slowing down of the AMOC. To shed light on this apparent contradiction, a new study...
