Rezension:
Best Site Good Work fluemarkt To counter the effect of the weaker Sun, carbon dioxide concentrations in the Earths atmosphere would need to have been 1,000 times higher than present, said lead author Bernard Marty, a professor at the CRPG-CNRS University of Lorraine. However, ancient fossil soils â?? the best indicators of ancient carbon dioxide levels in the atmosphere â?? suggest only modest levels during the Archean. Other atmospheric greenhouse gases were also present, in particular ammonia and methane, but these gases are fragile and easily destroyed by ultraviolet solar radiation, so are unlikely to have had any effect.
