Photomolecular evaporation of water – How sunlight alone evaporates without heat

(Abstract) “Although water is almost transparent to visible light, we demonstrate that the air–water interface interacts strongly with visible light via what we hypothesize as the photomolecular effect. In this effect, transverse-magnetic polarized photons cleave off water clusters from the air–water interface. We use 14 different experiments to…

Land Sink Now Degrading

  Duffy 2021 reports that within the last decade, the average global temperature for the warmest 3-month period passed the thermal maximum for photosynthesis. This means that on average, photosynthesis has peaked with warming and is now in decline, despite broadly accepted projections that photosynthesis would continue to…

Geoengineering Reduces Atmospheric CO2 Burden – Friedlingstein 2006

Summary - Reduced natural system sequestration with warmer temperatures causes extra carbon to remain in the sky. Any cooling, natural or human-caused, reduces natural feedback emissions which reduces the atmospheric carbon burden. Geoengineering does indeed reduce the atmospheric Greenhouse gas concentration. Abstract “Eleven coupled climate–carbon cycle models used…

Stratospheric Calcite Injection – Reduced ozone formation, Deep uncertainty

Flow tube experiment. (abstract) "We model ozone response incorporating the experimental uptake coefficients in the AER-2D model. With our new empirical reaction model, the global mean ozone column is reduced by up to 3%, whereas the previous work predicted up to 27% increase for the same SG scenario.…

Unanticipated side effects of stratospheric calcite injection?

Cloud Chamber bench experiment and modeling, (abstract) "Experimental and modeling results suggest particles will act as the nucleation sites for polar stratospheric cloud ice and, after sedimentation into the troposphere, impact cirrus clouds in the absence of other efficient ice nucleating particles. These results show that an overly…
