Los Angeles Times: The real climate change controversy: Whether to engineer the planet in order to fix it

„Most climate experts agree that the best way to keep global temperatures in check is to rapidly reduce emissions of carbon dioxide and other greenhouse gases by transitioning to clean energy sources. But scientists and policymakers are deeply divided over which forms of geoengineering also deserve serious consideration — and when the world might want to use them.“

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: 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. „

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.“
