"If the calculations of the Institute of Actuaries are borne out by 2050, then oil, gas and coal companies will murder half of the human species. And they will do it with the approval and support of most governments."

"The stark insanity of Hothouse Earth is that it is now more profitable for a handful of merciless corporates to stoke the furnace, accelerate global heating - and kill more people. Return on capital must now be measured in blood, not dollars." - Julian Cribb @juliancribb.bsky.social #climate

Hothouse Earth: arriving sooner than you think cribb.substack.com/p/hothouse-e...
Hothouse Earth: the smash is getting closer

What infuriates me is not only that we're poisoning our own water supply but also the water for all other species. "Humanity unthinkingly emits more than 220 billion tonnes of chemically-active substances every year into the environment – and most of them end up in water by one route or another."

Man the desert-maker, woman the healer

My intro to the polycrisis was his 2016 book "Surviving the 21st century: Humanity's 10 great challenges & how we can overcome them." Here he asks: "What will be history’s verdict on a civilisation that can invent artificial intelligence – but hasn’t the brains to manage and recycle its own waste?"

Overpopulation is pushing Earth past breaking point
Scientific evidence shows humanity has exceeded Earth’s long-term carrying capacity, placing growing strain on the systems that sustain life and increasing the risk of global instability.

Thank you, @juliancribb.bsky.social for this important warning! Even a "small #nuclearwar" would cause a global #collapse of #economy, #society. We need to overcome #hypernormalization & resist governments that put our lives and future at #risk with #war, #genocide cribb.substack.com/p/what-if-we...

Having slain over 200 million people since 1850, it is arguable that the nation state is the most destructive invention humans have ever made – and maybe it is now time to consign it to the garbage tip of history before it destroys us all.

"The fossil fuels sector is the primary driver of both CO2 and CH4 emissions and is showing every intention of increasing its activity. It screens this lethal activity behind a barrage of dishonesty, disinformation, distortion, and diversion." - Julian Cribb #global #climatechange #science #earth

"But we also need a majority of wise women in positions of power if we are to escape the fate which male aggression, overconsumption and overpollution are building for us. And a majority female population, engendered by global heating, could just help to achieve that."
