Another weapon to fight climate change? Put carbon back where we found it -- We’ll have to also remove carbon from the air -- Sequestration

Getting to zero carbon emissions won’t save the world. We’ll have to also remove carbon from the air—a massive undertaking unlike anything we’ve ever done.

Scientists and entrepreneurs like Aradóttir are embarking on ambitious—and sometimes controversial—projects to remove carbon dioxide from ambient air and lock it away. In Arizona, an engineering professor shows me his “mechanical tree,” a single one of which he says may someday be able to do the work of a thousand regular trees in capturing and storing CO2. In Australia, a leading oceanographer tells me that seaweed is salvation, if only we’d help it grow in giant aqua-gardens of kelp and wakame that could harbor billions of tons of carbon dioxide.

Atop a university building in Zürich, an Uruguayan inventor with a gleam in his eye presents me with a small vial of fuel made from nothing but sunlight and air. That may be the most intriguing of all the forms of carbon capture I’ve come across

What these efforts have in common is that they are geared in the long run to drag downward a number that climate experts agree holds the key to the health of the planet. That number is the atmospheric concentration of carbon dioxide, which for thousands of years had held stable at or a bit below 280 parts per million, until the industrial revolution kicked off in the middle of the 19th century. Today this critical number stands at some 420 parts per million—in other words, the percentage of CO2 in the atmosphere has risen roughly 50 percent since 1850.

Carbon-capture proponents say that their work—to capture the main driver of climate change, radically scaled up in coming decades—will help bring this number down.

” the percentage of CO2 in the atmosphere has risen roughly 50 percent since 1850.”

I DON’T BELIEVE YOU!

[devere]

Remove enough CO2 from the atmosphere and all life on earth will die. This is insane!

[OKSooner]

OK... the third greatest hoax ever perpetrated on humanity.

[bgill]

CO2 was many times higher during the Jurassic period than today.

STUPIDITY ABOUNDS!!

Indeed!

Carbon is what fuels the planet and all life. The more carbon the more life. The more carbon the more plants and less water needed to keep them growing.

The Sarah Desert is turning green because of the extra carbon. Green houses pump carbon dioxide to help plants grow faster. Carbon is food! It is a good thing.

It has NEVER been proven that carbon increases temperature or affects climate, it is a theory.

Stupidity abounds.

I know that. But we are dealing with Criminally Insane individuals who are running the Country. Courtesy of the 2020 election. They are just as bad and evil as the NAZI Hooligans as Hitler had running Germany in the 1930-45. And the end result will be the same. Hitler's bunch attacked European Nations including the Soviet Union. Biden Worshipers and Neo Cons are doing everything in their power to provoke and promote an full scale nuclear war between the Confederation of Independent States, AK/A , Russia. Of which there will be no winners and very few to none survivors.

[cweese]

Complete lunacy. Since Nat Geo went over the dark side many years ago (along with Scientific American) I don’t pay them much heed. They’re staffed with millenials/gen-Z morons who haven’t one clue.

[Candor7]

Bull crap.

The earth naturally sequesters carbon through many comprehensive organic processes, some of which are fairly quick and others take millenia.

National Geographic is full of lefty idiots who support the Climate Scam.They are a cult

Our ever changing climate has forced mankind to adapt and evolve for millenia. Without climate change, man would not have evolved to where he is now, indeed mankind's ancient migration around the world has been driven by climate change. Mankind's evolving technology has been driven by climate change for thousands of years beginning with irrigation which led to hydrology.Woitness Libyas former man made river whichi greened the Southern desert of Libya until the climate change cult supporters Obama and Hillery CLinton criminally destroyed it.A war crime which starved thousands of Libyans.

NOW we need to call out these ignorant climate cultists for what they are: totalitarianist bashibazooks, whose every answer to their fake climate change crisis results in the further reduction of freedom that mankind has enjoyed for millenia , individual freedom to respond to any serious climate change and adapt.

What these elite cultists want is a reduction of humankind's freedom , and as such it will assure mankinds failure to adapt to climate change.The strenghth of that adaptation depends on individual freedoms and freedom of adaptation, not a prosecution based on climate cultism.Its a totalitarian cult.

As it is now, the Village idiot of Canada, Justin Trudeau has insisted on a punitive carbon tax on farmers who do not have elctric farm vehicles by 2035, thereby reducing the food supply, increasing food costs , and ending the freedom Canadians have enjoyed to farm and have some of the best food production in the world.Klaus Schwab is in charge of this effort, which results in the reduction of population as demanded by the DAVOS crowd elitists.Bizarre.

National Geographic is a huge bizarro organization, I stopped reading them 20 years ago as they joined in with damning the Newfoundland Seal hunt, and demanded that everyone save polar bears that are supposed to be all dead by now.The polar bears are thriving and adapting as apex predators in the North.

We used to have a herd of buffalo that covered three large midwestern states, in their millions.They literally shook the earth when they migrated. They fed the native population for millenia, coast to coast. According to climate change cultists, the amount of methane they produced should have killed everyone. So how did human beings manage to survive that supposed ecological catastrophy?In Holland these cultists are demanding that farmers discontinue raising cattle because they pose an imminent thread to humanity. BIZARRE.

National Geographic needs a huge editorial change....fire the lot of these cultists.Otherwse National Geographic will remain as they are now, nothing more than a cowardly bizarro Chicken Little organization which works to prevent the freedom human kind needs to adapt to any change.

National Geographic....COWARDLY ORGANIZATION...run and managed from Davos.

[No name given]

Exactly.

[17th Miss Regt]

Off one of these green weenies and put their body in the ground. THAT will sequester carbon very efficiently!

[17th Miss Regt]

A few years back they were touting how icky chlorine was. If they could only remove all their chlorine from their bodies, we would not have to hear from them about this crap.

[beethovenfan]

CARBON DIOXIDE, NOT CARBON.

[Reeses]

How long before oxygen becomes the new enemy?

Oxygen wouldn't be hard to demonize. It makes fire possible, unlike CO2 which is used in fire extinguishers. Oxygen is not native to Earth's atmosphere, but is a pollutant from runaway invasive-species plant life, Earth's first greed-driven economy, unregulated by centralized planning bureaucrats. CO2 on the other hand is the star player in carbon cycle, the cycle of life.

‘STOP F****** around with nature. You’ll end up killing usall.’

God controls everything
these people end up killing us
God either cannot control these people, much less eerything
or God approves of these people killing us...

[curious7]

I guess these Dunning-Kruger type never heard that plants take in CO2 from the air. And produce O2.

[catnipman]

artificially removing CO2 from the atmosphere via chemical/mechanical means is absolutely guaranteed to INJECT even MORE CO2 into the atmosphere than it removes, even if so-called renewable energy is used, because THAT energy COULD have been used to substitute for petro-energy ...

even using unlimited fusion energy to power chemical/physical processes to remove CO2 from the atmosphere is still likely to produce more waste heat in the environment than just leaving the CO2 in the atmosphere ...

[to be clear, though, it’s ridiculous to even WANT to remove CO2 from the atmosphere in the first place]

Cool, but economically not feasible. Were it economically feasible, it would be utilized already. Pure stupidity; depends on funding by stupid politicians and subsidies from hoodwinked taxpayers. None are technically literate, but are emotionally driven. This insanity is aided by stupid journalists who didn’t learn much at all in journalism school.

[The_Media_never_lie]

The issue is not the issue. The issue is the revolution.

[Do_Tar]

Isn’t seaweed killing the coral reefs in Australia? Or, was that last year?

[HeadOn]

I have discovered a device which will end climate change for good. It’s called a ballot - The only problem is the American people don’t understand how to use it...
