What is carbon capture? And how does it work?
While carbon capture is regularly discussed in the media, no one really ever explains what it is.
Below is a quick thread discussing the technology behind traditional carbon capture 👇
Technology is connected to the "tailpipes" of these facilities and is used to remove CO2 from the plant exhaust.
This step is called "sequestration" and is why experts often talks about "carbon capture and sequestration" or "CCS".
Currently, one of the most economic forms of carbon capture is called "amine-based" capture.
An "amine" is a special liquid chemical which selectively grabs on to CO2 molecules.
The exhaust bubbles up through the column, and the amine drips down.
The liquid amine and gas exhaust mix in the column.

The amine with dissolved CO2 is sent into a second column where it is heated.
In the second column, the CO2 pops out of the amine.
Now, we have separated the CO2.

Below is a picture of an amine plant used for CO2 scrubbing.

The CO2 is injected into a well for permanent storage underground, usually a few hundred yards away.

What I've described is called "point source capture" because it captures CO2 from a single plant exhaust
With new advances in technology, CO2 can also be captured directly from the air we breathe

2) The leading hypothesis is that the new variant evolved within just one person, chronically infected with the virus for so long it was able to evolve into a new, more infectious form.
same thing happened in Boston in another immunocompromised person that was sick for 155 days.
3) What happened in Boston with one 45 year old man who was highly infectious for 155 days straight before he died... is exactly what scientists think happened in Kent, England that gave rise to #B117.
Immunocompromised 45 year old suffered from #COVID19 for 155 days before he died. The virus was changing very quickly inside the man's body\u2014it acquired a big cluster of >20 mutations\u2014resembled the same ones seen in #B117 & #B1351.

4) Doctors were shocked to find virus has evolved many different forms inside of this one immunocompromised man. 20 new mutations in one virus, akin to the #B117. This is possibly how #B1351 in South Africa 🇿🇦 and #P1 in Brazil 🇧🇷 also evolved.

Dr. Li couldn't believe what they found. "I was shocked," he says. "When I saw the virus sequences, I knew that we were dealing with something completely different and potentially very important." pic.twitter.com/HT3Yt6djFd
5) “On its own, the appearance of a new variant in genomic databases doesn’t tell us much. “That’s just one genome amongst thousands every week. It wouldn’t necessarily stick out,” says Oliver Pybus, a professor of evolution and infectious disease at Oxford.
Oil, gas, coal, solar.... all basically unchanged.
The key difference: A new forest the size of Brazil to suck up the extra CO2.

Including "nature-based solutions" in the outlook brings forward the date for net-zero emissions to 2058.
Without them their pathway for CO2 emissions is the same as the previous one.
(It's also towards the higher end of 1.5C emissions pathways.)

The "Brazil-sized" forest idea isn't actually new, it has been kicking around for a couple of years.
It was referenced in the "well-below 2C" scenario although not formally included in it, and Shell's CEO has been framing it as the only viable way of getting to 1.5C.

Fine, but who is going to plant all those trees? Well... Shell says it will plant some of them.
Only yesterday Shell said forests were a key part of its net-zero strategy.
Not everyone is convinced though

Shell plans to use forests to remove 120 Mt/yr of CO2 by 2030.

Appropriate land for forestation is finite, and risks competition with food production and human rights of current land owners/users, esp Indigenous
Given that Shell's 1.5C scenario also sees a big scaling up of bioenergy, the question remains: where are all those trees and bioenergy crops going to go?

The worst treatment was kept for the monkeys. The macaques breed of monkeys are small, relatively light primates, which are often used for animal experiments at LPT. \u2018They are kept in cramped conditions in small cages. https://t.co/6D0yisjd9B
