Prediction: The will blacken the skies with nanoparticles to cool the Earth.
- fsloth 6y agoIsn't 'Nanoparticles' in this case just a fancier word for 'soot'?
- lucb1e 6y agoWikipedia> Soot forms during incomplete combustion from precursor molecules such as acetylene. It consists of agglomerated nanoparticles with diameters between 6 and 30 nm. So yes, soot are nanoparticles, but that doesn't mean all nanoparticles are soot.
- tpnCC 6y agoThe relationship between soot aerosol and warming is complex. Black Soot may dim the sunlight,but may increase the warming by warming the snow. "A new study found that emissions of soot, or black carbon, alters the way sunlight reflects off snow and may be responsible for as much as 25 percent of observed global warming over the past century." https://www.nasa.gov/vision/earth/lookingatearth/Black_Soot.html https://www.nasa.gov/vision/earth/lookingatearth/Black_Soot.... Ash from the volcanoes on the other hand,can cause cooling depending on,among other factors,their composition. https://climate.nasa.gov/blog/183/ https://climate.nasa.gov/blog/183/ For example, the cooling observed due to Mount Pinatubo is due to Sulphuric Acid aerosol particles. https://earthobservatory.nasa.gov/images/1510/global-effects-of-mount-pinatubo https://earthobservatory.nasa.gov/images/1510/global-effects...
- wigl 6y agoCould be a reference to "geoengineering" patents like Myhrvold's StratoShield, but he is a huge patent troll so I doubt that development is far along.
