Science: Bioenergy plantations could fight climate change—but threaten food crops, U.N. panel warns

"In the effort to keep the planet from reaching dangerous temperatures, a hybrid approach called BECCS (bioenergy with carbon capture and storage) has a seductive appeal. Crops suck carbon dioxide (CO2) from the atmosphere, power plants burn the biomass to generate electricity, and the emissions are captured in a smokestack and pumped underground for long-term storage."

Independent: Pseudoscience is taking over social media and putting us all at risk

"The videos peddling the conspiracy theories received the highest number of views. And those spreading these conspiracy theories used terms like 'geoengineering' to make it seem like their claims had a scientific basis when, in fact, they did not."

Nature: Harvard creates advisory panel to oversee solar geoengineering project

"Plans to test a technique that would cool the planet by blocking sunlight are one step closer to reality. Harvard University in Cambridge, Massachusetts, has created an external advisory panel to examine the potential ethical, environmental and geopolitical impacts of this geoengineering project, which has been developed by the university’s researchers."

Market Business News: Geoengineered snowstorm could halt Antarctic ice collapse, save coastal regions

"The ice sheet that covers the west Antarctic is at risk of collapsing into the ocean. The destabilization has gone too far for greenhouse gas reduction to stop the collapse, although it might restore ice sheet stability in other parts of the continents."

Today online: Explainer: Can artificial snow save the West Antarctic ice sheet and prevent sea levels from rising?

"With the West Antarctic ice sheet starting to melt, which can lead to a rise in sea levels, a team of researchers has come up with a radical proposal: To artificially create snow to thicken up the ice sheet.

The Conversation: Why science needs the humanities to solve climate change

"When thinking about climate solutions, people often picture technical fixes. The IPCC reports list many ideas for climate change mitigation and adaptation. Mitigation reduces greenhouse gas emissions through technologies like renewable energy. Adaptation, such as building sea walls, aims to manage climate change impacts. It also includes schemes to engineer Earth’s climate system – for example, releasing chemicals into the stratosphere to reflect sunlight back into space."

Bloomberg Businessweek: We Already Have the World’s Most Efficient Carbon Capture Technology

"To help battle global warming, companies around the world are expected to spend billions of dollars over the next decade building devices aimed at sucking carbon from the atmosphere. The thing is, Mother Nature already made one. While each acre of most tree species can capture and store 1.1 to 9.5 metric tons of carbon dioxide a year, an acre of empress trees can absorb 103."

The Guardian: Sucking carbon out of the air is no magic fix for the climate emergency

"Negative emissions tech is important, but the idea it could replace decarbonisation is pure fantasy. Business as usual is not an option."

ScienceDaily: Clearing up the 'dark side' of artificial leaves

"While artificial leaves hold promise as a way to take carbon dioxide -- a potent greenhouse gas -- out of the atmosphere, there is a 'dark side to artificial leaves that has gone overlooked for more than a decade,' according to Meenesh Singh, assistant professor of chemical engineering in the University of Illinois at Chicago College of Engineering."
