Origin of The Arctic Climate
It is possible that this is the first time in the Earth's history that both poles have been simultaneously ice-bound. This unusual climate was created in the Azolla event when fresh surface water in the Arctic Ocean caused a long term abundance of Azolla, a type of aquatic fern. Huge quantities of dead Azolla built up and formed sedimentary rock, much of which contains fossil fuels as a result of the carbon contained in the Azolla. This process caused global cooling as a result of a reduction in the greenhouse effect. Release of stored carbon into the atmosphere as a result of current fossil fuel use is thought by most of the climate scientists to be causing global warming, which threatens to destroy the climatic conditions necessary for the current Arctic climate.It should be noted, however, that Earth is a dynamic system, wherein global warming and cooling occurs periodically based on multiple interacting stimuli.

Famous quotes containing the words origin of, origin, arctic and/or climate:
“Someone had literally run to earth
In an old cellar hole in a byroad
The origin of all the family there.
Thence they were sprung, so numerous a tribe
That now not all the houses left in town
Made shift to shelter them without the help
Of here and there a tent in grove and orchard.”
