Scrub a dub 🫧 ...except no scrubbing the delicate observatory optics! We don't use cloths or lens cleaner to clean the giant camera lenses. Instead, our summit staff use a high-speed stream of carbon dioxide "snow" to push debris off of the glass surface.

Sound familiar? If so, you might recognize this as the same process our team uses to clean the telescope's mirrors as well! This cleaning method effectively removes debris without leaving any residue or water marks that would otherwise decrease our data quality.

Any concerns on too high indoor CO2 levels may affect human health during and after the cleaning process?

And prints or snubs? Co2 cannot remove it!

Giant plasma tornadoes are raging on the Sun 🌪 The SDO space observatory has captured a spectacular sight: swirling vortices of plasma rising above the solar surface, comparable in size to our planet.

🚨 CLIMATE SCIENTIST REVEALS THE TRUTH! 🌍 CARBON DIOXIDE IS NOT THE PROBLEM…“In my training carbon dioxide and it’s rise or fall could explain everything that had EVER happened in our climatic history!”. The truth is that carbon dioxide has a logarithmic relationship with temperature, and as CO2 increases it has LESS of a warming effect. We are already at 99% of its saturation point, which means no matter how much more carbon dioxide we pump into the atmosphere, the Earth will NOT warm significantly in response. This makes the man-made climate argument, frankly, fall on it’s arse 🫡

‼️No True Leftist (w/B L A K E L E Y™℠©® LLC & James Li)‼️ A big conversation w/ two of my favorite lefty content creators about whether we have obligation to define & broaden the terms of debate, to push left, to co-opt mainstream spaces vs or creating our own, to use "woke" language or, alternately, to avoid turning off a mainstream audience by correcting the "unwoke", how to protest the right way, & whether to own our moral judgments instead of debating about procedure.

"If we halved the carbon dioxide content [in the atmosphere], we would have no life on Earth." Geologist Prof. Ian Plimer: "For about 80% of time [the atmosphere] was carbon dioxide rich... We had ice ages at the equator, and we had ice at sea level... yet the atmospheric carbon dioxide content was 20%." "And we're told that at 0.04%, if we increase it by a little bit, we're going to have runaway global warming. We didn't have it in the past, so why should we have it in the present?" "So we geologists see that this is a load of nonsense." "When we look over time, we see that carbon dioxide has decreased... We are at a dangerously low level. If we halved the carbon dioxide content, we would have no life on Earth."

Happy Pigs and Industrial Robots. In China, do pigs get high on carbon dioxide, enjoying a brief buzz of happiness before slaughter? Then, poof, they are sent to a robotic execution chamber for a clean and efficient process. In modern large-scale slaughterhouses, high concentrations of carbon dioxide are indeed used to stun pigs. Once lowered into a chamber filled with CO₂, the pigs lose consciousness within seconds due to severe hypercapnia and oxygen deprivation, allowing the slaughter process to proceed more efficiently.

We find a LOT of cool items underwater while cleaning up! Many folks ask how we clean the bottles & jars that we find, so we figured we’d try our best to explain our process. Some pieces take longer to scrub, but you’ll get the point by watching our video! 🤿❤️🧜‍♀️🫧

To my Indian friends, here is how does China use fully automated systems to complete the cleaning of a high-speed train in just 5 min. China has built the world’s largest high-speed railway network.

Australian geologist, Professor Ian Plimer: "No one has yet shown that human emissions of carbon dioxide drive global warming, and if they did, they'd also have to show that the natural emissions—and that's 97% of the total—don't drive global warming." "Then I look back in time through my geological eyes, and look at times in the past when we have very high carbon dioxide contents of the atmosphere, up to hundreds of times higher than now, and we see that we didn't have runaway global warming… But what we did have is six major ice ages, and there is no correlation over geological time between carbon dioxide in the atmosphere and temperature."
