matclab@ZLabe Do we now why methane did not rise between 1995 and 2005 ?
@matclab Scientists are still trying to pinpoint the cause of recent changes in methane concentration trends (e.g., wetlands). Here are some articles exploring possible sources/sinks: https://phys.org/news/2019-03-methane-atmosphere-surging-scientists.html & https://e360.yale.edu/features/methane_riddle_what_is_causing_the_rise_in_emissions & https://nature.com/articles/d41586-022-00312-2 & https://earthobservatory.nasa.gov/images/150967/why-methane-surged-in-2020

Lukáš Jelínek@ZLabe This company (Moravské naftové doly ~ Moravian oil mines) is still releasing huge quantities of methane to the air: https://www.irozhlas.cz/zpravy-domov/v-cesku-unika-do-ovzdusi-metan-za-miliardu-korun-rocne-rucni-brzda-proti_2504240640_dci
V Česku uniká do ovzduší metan za miliardu korun ročně. ‚Ruční brzda‘ proti oteplování nefunguje
Průmyslové úniky metanu jsou drahé a navíc výrazně přispívají k oteplování, které zažíváme. Přesto k nim ve velkém dochází, a to ve světě i v Česku, kde to od loňska zakazuje evropské nařízení.

@ZLabe ... thanks for sharing!
The summary is also worth reading and is very worrying if the development regarding the increase in greenhouse gases continues at this rate¹:
👉🏻 The AGGI in 2023 was 1.51, which means that we’ve turned up the warming influence from greenhouse gases by 51% since 1990.
👉🏻 It took ~240 years for the AGGI to go from 0 to 1, i.e., to reach 100%, and 33 years for it to increase by another 51%.
👉🏻 In terms of CO2 equivalents, the atmosphere in 2023 contained 534 ppm, of which 419 is CO2 alone. The rest comes from other gases.
👉🏻 CO2 is by far the largest contributor to the AGGI in terms of both amount and rate of increase.
👉🏻 Note: The IPCC suggests that a constant concentration of CO2 alone at 550 ppm would lead to an average increase in Earth’s temperature of ~3°C (5.4°F).

@ZLabe ... here comes the German translation:
Die Zusammenfassung ist ebenfalls lesenswert und sehr besorgniserregend, wenn die Entwicklung hinsichtlich der Zunahme der Treibhausgase in diesem Tempo weitergeht¹:
👉🏻 Der AGGI lag im Jahr 2023 bei 1,51, was bedeutet, dass wir den Erwärmungseinfluss der Treibhausgase seit 1990 um 51% erhöht haben.
👉🏻 Es dauerte ~240 Jahre, bis der AGGI von 0 auf 1 stieg, d. h. 100 % erreichte, und 33 Jahre, bis er um weitere 51 % anstieg.
👉🏻 In CO2-Äquivalenten ausgedrückt, enthält die Atmosphäre im Jahr 2023 534 ppm, wovon 419 ppm allein auf CO2 entfallen. Der Rest stammt von anderen Gasen.
👉🏻 CO2 trägt bei weitem am meisten zum AGGI bei, sowohl was die Menge als auch die Steigerungsrate betrifft.
👉🏻 Hinweis: Der IPCC geht davon aus, dass eine konstante CO2-Konzentration von 550 ppm allein zu einem durchschnittlichen Anstieg der Erdtemperatur um ~3°C (5,4°F) führen würde.

EndicottRoad59@ZLabe And this makes me wonder if the human race is too stupid to save itself.
Richard Michael Blaber@ZLabe The daily figure for CO2 for 23rd April from Keeling Curve is 430+ ppm, Zack. All those figures are bad - but none of the politicians on either side of the pond seem to care, except, perhaps, for the Greens here in Europe &, I imagine, the US & Canada. 74% of Americans want action on climate change (https://www.theguardian.com/environment/2025/apr/23/climate-action-politicians), but that didn't stop Trump's re-election.
a fish named dog ✡️♾️@ZLabe Oh, lovely.
Wait, do we trust NOAA data anymore? I mean, I'd assume it'd go in the opposite direction, but still.
@SpaceLifeForm @ZLabe not all nitrous oxide is funny. some of it, idk the exact formula, can create small holes in ur lungs and kill you. but that's only at a high concentration
@ZLabe what causes nitrous to rise?
@untakenusername Here is an overview: https://www.epa.gov/ghgemissions/nitrous-oxide-emissions
