What if we stopped pretending? The climate apocalypse is coming. To prepare for it, we need to admit that we can’t prevent it.

By Jonathan Franzen 8 September 2019 (The New Yorker) – “There is infinite hope,” Kafka tells us, “only not for us.” This is a fittingly mystical epigram from a writer whose characters strive for ostensibly reachable goals and, tragically or amusingly, never manage to get any closer to them. But it seems to me, in our […]

Breaching carbon threshold could lead to mass extinction – Carbon dioxide emissions may trigger “reflex” in global carbon cycle, with devastating consequences

By Jennifer Chu 8 July 2019 (MIT News) – In the brain, when neurons fire off electrical signals to their neighbors, this happens through an “all-or-none” response. The signal only happens once conditions in the cell breach a certain threshold. Now an MIT researcher has observed a similar phenomenon in a completely different system: Earth’s […]

13 November 2009 (Desdemona Despair) – When Zeus filled Pandora’s jar with the evils of the world, he saved Delusional Hope for last – to prevent humans from committing mass suicide as they were overcome by the other evils.
