Solar Radiation and The Greenhouse EffectHow Greenhouse Gases Affect Global WarmingSources of Greenhouse GasesOur Planet's FutureGlobal warming isn't a new concept in science. The basics of the phenomenon were worked out well over a century ago by Svante Arrhenius in 1896. His paper, published in the Philosophical Magazine and Journal of Science, was the first to quantify the contribution of carbon dioxide to what scientists now call the greenhouse effect.The greenhouse effect occurs because the sun bombards Earth with enorm…See more on livescienceAmmonium sulfate(NH4)2SO4 - PubChem sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of ammonia.A high-melting (decomposes above 280℃) white solid which is very soluble in
