Imagine dimming the Sun to cool the Earth.
It sounds like science fiction – but it’s a real idea being discussed by scientists, governments, and climate researchers right now.
In this episode of The Science Vault, we dive deep into the controversial world of geoengineering:
– Solar Radiation Management (SRM) – dimming sunlight with stratospheric aerosols and cloud brightening
– Carbon Dioxide Removal (CDR) – direct air capture, enhanced weathering, BECCS and more
We explore the promise: rapid cooling, slowing melting ice, buying time to transition to renewable energy…
And the peril: regional weather disruption, ocean acidification, unknown side effects, moral hazard, and the terrifying question of who controls the global thermostat.
Is geoengineering humanity’s last hope against climate change… or a dangerous gamble with the only home we have?
