High Quality Content by WIKIPEDIA articles! Cretaceous polar forests were temperate forests that thrived at polar latitudes at the end of the Mesozoic Era during an interglacial time known as the Cretaceous Period 145-65 Ma. During this period, global average temperature was about 10°C warmer and carbon dioxide levels were approximately 1000 parts per million (ppm), 2.5 times the current concentration in Earth’s atmosphere. The abundance of atmospheric carbon dioxide (CO2) had a very significant impact on global climate and Earth’s natural systems. The concentration of atmospheric CO2 is considered one of the main factors in the creation of an extreme greenhouse Earth during the Cretaceous with a very low average global temperature gradient. As a consequence, high paleolatitudes in both hemispheres were much warmer than the present. This temperature gradient was partially responsible for the lack of continental ice sheets in polar regions. Данное издание представляет собой компиляцию...
