Scientists are worried about plans to use geoengineering to cool the Arctic, fearing it's too risky and may not work.
These ideas, like spraying things into the atmosphere or altering sea ice, could have unpredictable side effects.
The most effective way to address climate change is to reduce greenhouse gas emissions and reach net-zero.
Relying on experimental geoengineering techniques instead of addressing the root causes could worsen climate problems.
