"Using a climate model, researchers quantify the sensitivity of the tropical monsoon precipitation to the meridional distribution of volcanic #SulfateAerosols prescribed in the #stratosphere in terms of the changes in aerosol optical depth (AOD)." 2/9
"In the experiments, large changes in summer monsoon π§οΈ in the tropical monsoon areas are simulated, mainly over the Indian region, in alliance with meridional shifts in the location of the intertropical convergence zone caused by changes in interhemispheric AOD differences." 3/9
Based on the simulations of this study, authors "estimate a sensitivity of β1.8°±0.0Β° meridional shift in global mean ITCZ & a 6.9Β±0.4% reduction in NH monsoon index (NHMI; summer monsoon precipitation over NH monsoon regions) /0.1 interhemispheric AOD difference (NH-SH)." 4/9
This study also "quantify the sensitivity in terms of interhemispheric (IH) differences in effective #RadiativeForcing & IH temperature differences: 3.5Β±0.3% change in NHMI per unit (Wmβ»Β²) IH radiative forcing difference & 5.9Β±0.4% change/unit (Β°C) IH temp. difference." 5/9
"Similar sensitivity estimates are also made by the researchers of this study for the Indian monsoon precipitation." 6/9
"The establishment of the relationship btw interhemispheric AOD (or radiative forcing) differences and ITCZ shift as discussed in this paper will further facilitate and simplify understanding of the effects of #StratosphericAerosolGeoengineering on tropical monsoon rainfall." 7/9

π¨A NEW study explores a theoretical #geoengineering approach to combat global warming β by altering Earthβs orbit.
Simulations suggest that shifting Earth ~5.8% farther from the Sun could cool the planet by roughly 7K, effectively offsetting projected warming.
DETAILSπ§΅1/10
2/ Climate models suggest global temperatures could rise by 7K by 2100, driven by greenhouse gas emissions.
This study asks: what if, instead of changing the atmosphere, we changed our position in space?
Specifically: increase Earthβs orbital radius.
3/ Basically, the paper builds on the science of Milankovitch cycles which is slow, natural variations in Earthβs orbit and tilt that have triggered past ice ages.
These cycles show that even slight orbital changes can dramatically affect climate.
