Climate change causes inflation now too. Quick, put on more solar panels….!

Starving for any attention, the carbon-haters need to find a reason to get into the inflation debate. CO2 keeps rising but crops are up, forests are greener, tropical islands are growing, mangroves are expanding, and the world is in more danger of being overrun with cheap soy and corn than by rising seas. Whatever. The disaster-bus will find a way to blame fossil fuels for everything that’s bad, as if through some miracle EV’s and windmills will make pork cheaper.

It’s a cult:

Climate crisis is ‘battering our economy’ and driving inflation, new book says

Edward Helmore, The Guardian

Forget Ukraine, coronavirus, corporate greed and “supply chain issues”, when it comes to inflation the climate crisis is the real, lasting, worry, according to a new book, and one that’s only likely to get worse. Climatenomics lays out how ‘supply chain disruptions’ has become a euphemism for the effects of climate change

“I don’t think people have realized that climate change is an economic issue now because it’s always been seen as an environmental, health or social issue,” says Keefe. “The fact of the matter is climate change is battering our economy.”

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.
