Digital Trends: Climeworks wants to clean the atmosphere with a fleet of truck-sized vacuums

"Engineers at Climeworks think they have a solution. Using machines that resemble jet engines, the Swiss startup wants to extract CO2 from thin air. From there, the gas can be siphoned off and sold to carbonated drink companies as fizz for sodas and agriculture companies as fuel for crops. Climeworks already has a deal with Coca-Cola, and it pipes CO2 to a greenhouse that grows tomatoes and cucumbers adjacent to its flagship plant in Hinwil, Switzerland."

The Conversation: New CO₂ capture technology is not the magic bullet against climate change

"According to a recent major UN report, if we are to limit temperature rise to 1.5 °C and prevent the most catastrophic effects of climate change, we need to reduce global CO₂ emissions to net zero by 2050. This means eliminating fossil fuel use fast – but to cushion that transition and offset the areas in which there is currently no replacement for combustibles, we need to actively remove CO₂ from the atmosphere. Planting trees and rewilding are a large part of this solution, but we are highly likely to need further technological assistance if we are to prevent climate breakdown. "

CBSnews: Capturing carbon, once a fringe idea, may be key to fighting climate change (video)

"Despite decades of warnings from climate scientists, the world is still struggling to cut down its CO2 emissions, the main driver of climate change. But a handful of researchers and private companies are trying to fill in some of the gaps with an idea that was once considered fringe: capturing carbon."

Motherboard: Climate ‘Realists’ Are Delusional

"Geo-engineering refers to the projection of sunlight-reflecting aerosols into the atmosphere, combined with using carbon removal technologies designed to induce chemical reactions that absorb carbon from the air, among other still-theoretical technologies that proponents say would put humans more in control of the Earth’s atmosphere and climate."

Business Insider Deutschland: We’re altering the climate so severely that we’ll soon face apocalyptic consequences. Here are 11 last-ditch ways we could hack the planet to reverse that trend.

"Geoengineering is a term that refers to technology that can alter Earth's natural cycles to cool down the planet. It's being increasingly discussed as a potential way to address climate change. Putting mirrors in space, capturing carbon dioxide, and seeding clouds with particles are all ways of manipulating weather or the atmosphere. But some scientists and politicians think geoengineering could damage the planet or lead to war."

Digital Trends: Geoengineering is risky and unproven, but soon it might be necessary

"Imagine the azure blue skies of summer fading to a hazy white as light-scattering aerosols are injected into Earth’s upper atmosphere. Imagine a planet covered with giant artificial chemical sponges leeching gases out of the air that we breathe. Imagine filling the Earth’s oceans with millions of pounds of calcium bicarbonate to alter the levels of acidification."

Forbes: IEA Challenged to Address Limits to Negative Emissions

"The WEO offers the authoritative global outlook on the mix of fuels that will supply our energy decades into the future and, by extension, the level of carbon dioxide emissions that will result. Reverence for the document is so great in government and industry that some maintain that it does more than merely project the future, but in fact defines our path toward it."

Stone Pier Press: Turning carbon dioxide into fish food?! It can be done.

"If you’d told me a month ago there’s a company working on removing carbon dioxide from the atmosphere and using it to feed fish, lots and lots of them, I’d have told you to go back and get your story straight. But Novonutrients, a California startup, is on the verge of doing exactly that."
