As part of a climate engineering push to cool the planet, scientists have made machines with huge fans to suck in the carbon dioxide from the air and are preparing to release chemicals from a balloon to dim the sun’s rays.
Supporters of these risky and often, expensive projects say that it has become imperative to use these scientific measures so as to meet the goals of Paris Agreement to curb global warming that is creating havoc in many parts of the world by causing heat waves, excessive downpours and rising sea levels.
A Swiss company named Climeworks in May started the world’s first ‘commercial carbon dioxide capture plant’. The $23 million project in a countryside near Zurich uses giant fans and filters to suck in greenhouse gases from thin air.
Another outcome of recent university research is a Harvard geo-engineering project which aims to dim the sunlight to cool the planet. Harvard's David Keith and his team will release 1 kilo of sun dimming material from a high altitude balloon above Arizona next year and study its effects on microphysics of the stratosphere.
However, experts opine that instead of spending huge amounts on expensive projects involving new technology, countries should strive to cut emissions which are the main cause of global warming.
