50:31 | 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?

Should we reflect sunlight to cool the planet?

Should we reflect sunlight to cool the planet?

9:56 | Solar geoengineering happens in nature when huge volcanic eruptions cover the stratosphere with ash. Solar geoengineering takes advantage of that principle, using different scientific methods to make the planet more reflective overall.

Fine-tuning the climate

42:25 | Engineers and scientists are trying to intervene in the Earth’s geochemical cycles. Because it appears efforts to cut CO2 won’t suffice to avoid irreversible climate change. But does geoengineering offer a real solution? Or is it just human hubris?

The new urgency of climate change

The new urgency of climate change

10:45 | The coronavirus brought much of the world to a standstill, dropping carbon emissions by five percent. Al Gore says keeping those rates down is now up to us.

42:26 | Scientists are testing new technologies they hope could counteract the effects of climate change. But how could that work on a global scale? And – if it is possible at all – what are the dangers?

Emergency medicine for our climate fever

Emergency medicine for our climate fever

14:49 | As we recklessly warm the planet by pumping greenhouse gases into the atmosphere, some industrial emissions also produce particles that reflect sunshine back into space.

Geoengineering – can we suck the CO2 out?

Geoengineering – can we suck the CO2 out?

13:34 | Geoengineering has really split the scientific community. Some believe we’ll be meddling even more with the balance of our biosphere without really understanding the consequences. Others believe we’ve got nothing to lose.

29:11 | Professor Daniel Cziczo explains the CO2 problem and the three major types of geoengineering. We learn why the only viable approach is CO2 sequestration — pulling the CO2 out of the atmosphere.

Der findes mange fantasifulde forslag til alternative tekniske løsninger på klimakrisen. Men de fleste er forbundet med betydelige udfordringer eller risici.
