Wer sich im Kampf gegen Diskriminierung auf “Neutralität” beruft, stellt sich auf Seiten der Diskriminierung, anstatt sie zu bekämpfen.

🛰️ TROPOMI and other, upcoming satellites offer the opportunity to check if these changes will indeed lead to the envisioned reduction in air pollution from ships.

Thanks to all co-authors for making this possible!

🛳️These findings are in line with in-situ, near-coast measurements and indicate that MARPOL ANNEX VI - which regulates ship NOx emissions - is ineffective in reducing air pollution.
In response, the International Maritime Organization (IMO) has announced ammendments to the regulations just last week

In the paper we show:
1️⃣ It is possible to estimate individual ship emissions from space.
2️⃣ These emissions follow a pattern: Newer ships, which have to follow more stringent emission limits, emit more NOx
3️⃣ Emission factors are highest for ships sailing slow

China built more solar power in the last 8 months than all the nuclear power built in the entire world in the entire history of human civilisation.

Fair point.
Sounds like you need a thermostat and do some experiments. Added bonus: more Glühwein ;)

Pretty sure the idea is to heat up to below the boiling point of ethanol ;)

Pepernoten are by far the best culinary thing of the Netherlands! Can't believe I missed out for 26 years of my life

I am incredibly grateful to my supervisors, collaborators, and everyone who I could share this special day with. I am very happy with the results of 4+ years of work and hope the results will lead to a more livable planet.🌍🚢
