I’ll be honest. “Don’t Look Up” had me at the opening scene.

The Rise and Fall of the "Atlantic Multidecadal Oscillation"

Two decades ago, in an interview with science journalist Richard Kerr for the journal Science, I coined the term the "Atlantic Multidecadal Oscillation" (the "AMO" for short) to describe an internal oscillation in the climate system resulting from interactions between North Atlantic ocean currents and wind patterns. These interactions were thought to lead to alternating decades-long intervals of warming and cooling centered in the extratropical North Atlantic that play out on 40-60 year timescales (hence the name).

On The Importance of Diversity in Climate Communication

In light of recent social media posts and conversations I've had with colleagues, I want to take this opportunity to make a statement about the importance of lifting the voices of women, people of color, and other voices that have been marginalized in the world of science communication, including the discourse over climate change.

On Tropical Atlantic Warmth and Hurricanes

A new study just out in Science attributes the unusually active 2017 Atlantic hurricane season to tropical Atlantic warming. Furthermore, it attributes that warmth to human-caused climate change (a combination of increasing greenhouse gas concentrations and sulphate "aerosols" from industrial pollution).
