Not rainfall as such, but certain types of meteorites contain water. I've seen online, estimates of between 37,000 and 78,000 tonnes of them entering Earth's atmosphere per year. So, we do get water from space.Could someone clarify something floating within my mind please?
There is no rainfall from Space so rising sea levels are from the conversion of Ice or Vapour into liquid and any expansion due to heat retention with Global Warming a probable cause.
Happy to be corrected!
We certainly do add water to the atmosphere through emissions. The burning of any substance is 'Oxidation' i.e. the chemical reaction of a substance with Oxygen (O2). Seeing as most things that we burn (fossil fuels, wood etc) are composed largely of Carbon (C) and Hydrogen (H), then a large amount of the products of Oxidation are going to be the Oxides of Carbon (CO, CO2) and the primary Oxide of Hydrogen (H2O).Do we add to it through the emissions? Particles of dust, attract moisture therefore turning into rain. Could be wrong.
