Exaggerating the risks (Part 5: Climate wrap-up)
In a last look at climate risk, I examine two final mechanisms by which climate change could lead to existential catastrophe: moist and runaway greenhouse effects, and interstate conflict. Then I draw lessons from the discussion of climate risk in Parts 2-5 of this series.

Existential risk pessimism and the time of perils (Part 8: Implications)
Suppose I’m right that there is an enduring tension between Existential Risk Pessimism and the Time of Perils Hypothesis. What follows?

Belonging (Part 4: TIME’s up?)
A TIME magazine investigation alleges a “toxic culture of sexual harassment and abuse” within effective altruism. I look at the original article and the community’s subsequent reaction. Content warning: sexual harassment and abuse; racism; sexism.

Existential risk pessimism and the time of perils (Part 7: An application)
I apply lessons learned about the value of existential risk mitigation to assess the cost-effectiveness of biosecurity. Leading cost-effectiveness estimates turn out to be overstated by several orders of magnitude because they do not appropriately model background risk.

Exaggerating the risks (Part 4: Halstead continued)
I continue to make the case that estimates of existential risk from climate change have been exaggerated, looking deeper into the Halstead report discussed in Part 3 of this series.

Belonging (Part 3: Reform)
Nick Bostrom’s email and subsequent apology have sparked fresh discussions about inclusion and belonging in effective altruism. Who is or can be an effective altruist? Whose voices will be heard? I discuss recent calls for reform and suggest tangible avenues for evidentially-supported improvement.

Belonging (Part 2: The tide may be turning)
How has the effective altruist community reacted to Bostrom’s email and apology? Initially, many reactions were not good, but there are signs of improvement. What might we hope for the future to bring, and how can we get there?
