I am a professor and author. I use complexity science to examine threats to global security—especially economic instability, environmental stress, ideological polarization, and mass violence—and how people, organizations, and societies can respond to these threats.

WHAT’S NEW
The great Canadian climate delusion
with Yonatan Strauch | Is Canada going to be the first country to break apart over the issue of climate change? That may seem like a hyperbolic question. But the fissures in our federation over climate and energy policy are now extraordinarily deep, and there’s little sign that they’ll close soon.
Trump could declare a national emergency: predicted in October 2016
with Jack Goldstone | "Mr. Trump would quickly reshape the context within which his presidency operates by generating a new political and social reality – an ‘emergency’ in America and around the world – that justifies and even demands attacks on democratic institutions."
World Government Summit
This February 2017, Thomas Homer-Dixon spoke at the World Government Summit on "Climate Change and Food Supply."
No . . . I did not say wind energy is ‘Idiot Power’
A poster widely circulated on the Web highlights text that was purportedly written by me saying that wind power inevitably suffers an energetic deficit. The poster is fraudulent. I didn't write the text, the text itself is selectively quoted, and the argument it makes, taken in isolation, is meaningless.
Crisis analysis: How much damage can Trump do? (A lot)
Trump’s performance so far suggests his administration will lurch from crisis to crisis. To make some sense of these outcomes, I’ve charted the most likely crisis types and their causes.
How Alberta could champion a new energy source
Albertans may well wonder if a plague of locusts will come next. From the 2013 floods, to the oil price collapse and the resulting fiscal crisis, to the Fort McMurray fires, the province has taken some heavy blows.

RESEARCH
Synchronous Failure: The Emerging Causal Architecture of Global Crisis
by Thomas Homer-Dixon et al. | Recent global crises reveal an emerging pattern of causation that could increasingly characterize the birth and progress of future global crises. A conceptual framework identifies this pattern’s deep causes, intermediate processes, and ultimate outcomes.
The Conceptual Structure of Social Disputes: Cognitive-Affective Maps as a Tool for Conflict Analysis and Resolution
Thomas Homer-Dixon et al. | We describe and illustrate a new method of graphically diagramming disputants’ points of view called cognitive-affective mapping. The products of this method—cognitive-affective maps (CAMs)—represent an individual’s concepts and beliefs about a particular subject, such as another individual or group or an issue in dispute.
A Complex Systems Approach to the Study of Ideology: Cognitive-affective Structures and the Dynamics of Belief Change
Thomas Homer-Dixon et al. | We propose a complex systems approach to the study of political belief systems, to overcome some of the fragmentation in the current scholarship on ideology.
