New disasters can happen if countries decide to unilaterally try technological fixes to global Warming.

With record-breaking heatwaves hitting many parts of the world over the last few months, scientific circles have been hotly debating whether countries should prepare to deploy geoengineering technologies to deal with such climate emergencies. Should these technologies be deployed by an international body or by individual countries?

Geoengineering is an umbrella term for various experimental technologies designed to deliberately alter the climate system to reduce the impacts of global warming. They are slowly but steadily gaining salience and broadly fall under two categories: Solar Radiation modification (SRM) and Carbon Dioxide Removal (CDR) technologies.
