​VPRO Backlight dives into the world of climate engineering: scientists and start-ups trying to use technological means to cool the earth. How hopeful or risky are these techniques?

The planet is heading for a feverish warming. With each additional degree, the climate is changing dramatically: sea levels are rising, the ice at the North Pole is disappearing and entire species of animals are being wiped out. Of course we need to emit less CO2. But despite 25 years of climate agreements and fine promises, emissions are still increasing. If we don’t act harder, we are lost.

Could climate engineering be the emergency solution we need? Can these techniques and ideas cool the planet? And how risky are they?
