Study Human extinction? Climate doomers want to find a nuclear-winter-level scare to motivate people

I’m rating this a full instant BINGO on the climate change propaganda card.

Climate change just isn’t scary enough. The Merchants of Panic want to find the climate change equivalent of the Nuclear winter Bomb Scare “to compel” people:

Climate change: More studies needed on possibility of human extinction

Climate change just isn’t scary enough

The BBC (thinks this is news)

Catastrophic climate change outcomes, including human extinction, are not being taken seriously enough by scientists, a new study says.

We know if they set up a committee to find “human extinction events” they will find them. We get what we pay for:

The authors say that the consequences of more extreme warming – still on the cards if no action is taken – are “dangerously underexplored”. They argue that the world needs to start preparing for the possibility of what they term the “climate endgame”.

We need these doomer studies apparently — because people have written pop science books predicting doom:

According to this new analysis, the closest attempts to directly understand or address how climate change could lead to global catastrophe have come from popular science books such […]

Octopuses will go blind thanks to climate change

Octopuses survived the meteor that wiped out the dinosaurs, but look set to go blind thanks to coal fired power and your car.

Octopuses may go blind from climate change, study warns

Plastic pollution and climate change may be significantly altering the level of oxygen on our planet. Now, a new study dives into the impact it could have on marine life, including squids, crabs and octopuses – blindness.

The study, published in the Journal of Experimental Biology, highlights how important oxygen is to sight and retinal activity for certain marine larvae. Tiny declines in oxygen levels result in significant vision impairment, including almost total blindness in certain species.

“Using in vivo electroretinogram recordings, we show that there is a decrease in retinal sensitivity to light in marine invertebrates when exposed to reduced oxygen availability,” the study’s abstract reads. “We found a 60-100 [percent] reduction in retinal responses in the larvae of cephalopods and crustaceans…

Or more specifically: Octopuses will go blind if they are suddenly dumped in tanks with reduced oxygen…

To test the theory, the animals were put in reduced oxygen environments for approximately 30 minutes.
