Klimaendringer og rensing av luftforurensning gjør jordkloden mørkere

It's horrifying to see #Melissa intensifying right up to landfall - I dread to think what will happen in Jamaica, with up to a metre of rain forecast 🧪 But it's clear why Melissa is so powerful - it was fuelled by waters made abnormally warm by global heating: www.newscientist.com/article/2501...

Our climate seems to be more sensitive to greenhouse gases than we thought, which means we have to up our decarbonisation efforts.

"Emissions have basically stabilized and accordingly the annual increase in atmospheric CO2 has stabilized (it spiked in 2016 and 2024 due to El Nino events but if you neglect those individual spikes the data show a clear leveling)," Mann. That, seriously, is about as wrong as it is possible to be:

The climate impact of a #hydrogen economy: We welcome contributions to our session at the #EGU25 in Vienna & online. We aim for a better understanding of a hydrogen budget and impacts of hydrogen use. Deadline for abstracts: 15 January 2025 meetingorganizer.copernicus.org/EGU25/sessio...

Repost this if you’re old enough to remember when they tried to convince us that “global warming stopped in 2008” (or whenever).
