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.

Thank you, Candor7!

All Globull Warming, now re-titled “Climate Change” pushers are not only members of a cult, they KNOW it’s a lie. It’s merely a tool of tyranny and depopulation. There’s going to be (already is) depopulation because vaxes are killing many, and destroying fertility as well.

[Candor7]

The latest numbers world wide re 6 million died from covid. !7 million died from the vax.

We shoiuld never except similar government tyranny in our lives. NEVER AGAIN.

[alancarp]

From 0.028% to 0.045% over 170 years. Oooooo... scary.

That is why the criminals in government and elsewhere in power need to be arrested for their crimes.

And most of those who died of covid would not have died if they had been given the drugs that treat it - Ivermectin and Hydroxychloroquinine - and had not been given Remdesivir - “Run Death is Near” and intubation.
