Niepewności w kwestii CO2 na tle globalnego ocieplenia
PublicationDitlenek węgla to powszechnie znany gaz, uczestniczący m.in. w procesie fotosyntezy. W ostatnich latach zyskał on jednak miano czynnika, który w głównej mierze przyczynia się do powstania efektu cieplarnianego, a walka z emisjami CO2 stała się jednym z najważniejszym elementów polityki UE. Powiązanie tezy antropogenicznego wpływu na ocieplenie klimatu ze wzrostem stężenia ditlenku węgla w atmosferze, pociągnęło za sobą konsekwencje...
