An aspect is that ALL #aerosols are max 1-micrometer to not drop like tiny stones, unoxidized aluminum 0.1-1.0nm reflect less than 5% of visible means 95% heats the aerosol mass to act as a #quantum_dot absorbing the insolation to re-emit it in all directions heats the airmass they're in any altitude ! Sulfur products advertising the reflect near 100% failed to realize this heats the airmass they're in any altitude ! Add in pollution, soot etc these act as a separate, concurrent, intermingled greenhouse_system from CO2's, they heat each other far more than they cool at lower altitudes the issue The extra heat jumps #sealevel rise expectations to 1.4-2.1m/4.6-6.9ft by 2100, 75yrs away my bet 2m, Rignot's max 4m/13ft comin' at cha', 2019, 25;33, https://t.co/hQnk6f4m5k The 1200 Islands of the #Maldives average 1.5m above MSL #Chemtrails are OPTIONAL and DON'T COOL, they HEAT the atmosphere the game now And, legally, any law allowing this without consequences considered isn't "legal" by #jurisprudence that essentially legalizing crimes as if #TheBeltway cares they do #genocide for_profit ? <grok >### **Conclusion** The aerosol layer’s self-heating is a **greenhouse effect in reverse**: it warms the stratosphere while cooling the surface, with nighttime LW trapping blunting radiative cooling. To quantify this: - Use **diurnally resolved radiative transfer codes** (e.g., SBDART). - Track layer temperature ($ T_a $) and surface OLR in coupled models. - The “greenhouse” efficiency of SAI is ~30% of CO₂’s per W/m² forcing, but with critical day-night asymmetry. This framework explains why **nights warm faster** under SAI: the layer’s LW trapping is a persistent, cumulative effect, while daytime cooling is transient.<grok >
