"Exploring Unconventional Methods to Combat Global Warming"

In the face of insufficient progress in reducing greenhouse gas emissions, scientists are exploring unconventional and controversial methods to combat climate change, including brightening marine clouds, reflecting sunlight with particles, building underwater walls to shield glaciers, using mechanical trees to capture carbon, and dumping sodium hydroxide into the ocean to lower acidity and absorb CO2. While these ideas are being tested, some caution against potential environmental risks and advocate for strict oversight.
