"Currently we are on a path to end up between 2.5 to 3°C warming." "That's more than the double of warming yet to come"

...Methan in CO2 umwandelt, wird das Treibhausgasproblem durch a) den kumulativen Effekt und b) die Transformation in Wasser und Kohlendioxid als noch potentere Treibhausgase noch größer (s/:super!/s)
ad b) Keine Ahnung, ob es das schon gibt, aber müsste man aufgrund der verschiedenen Treibhausgase und des #RadiativeForcing-Efekts 1) nicht Umdenken und 👉von "Treibhausgasäquivalenten" reden? 👈
Die "Hälfte" von der du da redest, wird...
New research on the potential for radiative forcing of the climate from satellite re-entry debris: "We find that reentry-ablated alumina particles have ... a cooling radiative forcing of approximately -0.378mW/m2."

Numerous satellite operators are building megaconstellations in Low Earth Orbit (LEO) with hundreds of satellites, placing new satellites and spent rocket stages in orbit. Once these objects fail, they are often removed from LEO via atmospheric reentr

"This strongly absorbing organic aerosol species is water insoluble, resists daytime photobleaching and increases in absorptivity with night-time atmospheric processing" [3] so that the "parameterizations of brown carbon in climate models" may "need to be revised to improve the estimation of #smoke #aerosol #RadiativeForcing and associated #warming", with potential consequences for the current #ClimateChange estimates
A new study shows that global atmospheric dust—microscopic airborne particles from desert dust storms—has a slight overall cooling effect on the planet that has hidden the full amount of warming caused by greenhouse gases.
