This Scientist Made a Super-Tree to Fight Climate Change

Lackner and his team at Arizona State University are developing technology to capture carbon dioxide from the atmosphere, viewing it as a waste management issue. Inspired by trees, they aim to create synthetic versions that are more efficient. Their material can absorb CO2 and release it for reuse, potentially aiding in reducing emissions. Despite challenges in scaling and cost, the technology shows promise. Critics worry it may reduce the urgency to cut fossil fuel use, but the need for solutions is pressing.

What scale of cleanup is Lackner interested in regarding CO2 emissions?

What does Lackner suggest about the future of this technology compared to solar panels and windmills?

What concerns do critics have about the technology for scrubbing CO2 from the atmosphere?
