The billionaire class corrupts governments and prevents them from taking obvious actions to address climate change.
Why, then, didn't our governments do these obvious things? Because they didn't want to do them. Why not? Because they're corrupted by the billionaire class.

The American two-party system is designed to suppress the left and maintain the status quo for billionaires.
The two-party system in America is designed to suppress the left through a "lesser of two evils" voting system. Corporate Dems are able to dominate the Democratic party by pulling as-big-as-necessary donations from the billionaire class.

The current summer is the coolest summer for the rest of one's life.

Climate breakdown is a planetary-scale symptom of underlying collective trauma from five hundred years of extractive colonial capitalism.
As I've said many times, climate breakdown is nothing more (or less) than the most planetary-scale symptom of the underlying collective trauma from five hundred unhealed, accumulated years of extractive colonial capitalism.
Climate Human Said 14 Jun 2025
Planetary breakdown cannot be stopped without also addressing collective trauma.
We can't stop planetary breakdown without also addressing this collective trauma, and we can't address this collective trauma without also working on our own healing.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they do, this site shows a machine translation beneath the post, in this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the serif above is exactly what the person published, and it is what to quote them on. A translation can be wrong in ways that matter, especially about tone.
Only the post's own words are translated. A quoted post, a linked article and a belief on korrents.com are left in their original language.
