Summary

Story summary

A study in "Frontiers in Science" critiques five polar geoengineering proposals as infeasible and environmentally risky.
Techniques like glass bead scattering and sea curtains may disrupt marine ecosystems and cost up to $80 billion.
The report highlights "termination shock," a rapid warming risk if geoengineering efforts cease, stressing continuous operation.
Experts advocate for proven climate solutions, such as decarbonization and renewable energy, over speculative geoengineering.
The study urges prioritizing the protection of polar regions instead of pursuing risky technological fixes.
