9. september 2023 | Klimakrisen
11:39 | You may know laughing gas from your visit to the dentist. But did you know that it’s actually a climate killer – 300 times as potent as CO₂? Why is no one talking about it? And how can we to stop it?
26. august 2023 | Transport
9:33 | The shortest flight in Europe takes less than a minute – and it’s getting increasingly hard to justify emissions from such trips as the planet heats up.
