600 to 800 million years ago—a period of time geologists call the Neoproterozoic—evidence suggests the Earth underwent an ice age
so cold that ice sheets not only capped the polar latitudes, but may have extended all the way to sea level near the equator. (That would have ruined a Punta Cana vacation more than Sargassum).
Reflecting ever more sunlight back into space as they expanded, the ice sheets cooled the climate and reinforced their own growth. Obviously, the Earth didn’t remain stuck in the freezer, so how did the planet thaw?
Thank the Volcanos:
Even while ice sheets covered more and more of Earth’s surface, tectonic plates continued to drift and collide, so volcanic activity also continued. Volcanoes emit the greenhouse gas carbon dioxide. In our current, mostly ice-free world, the natural weathering of silicate rock by rainfall consumes carbon dioxide over geologic time scales. During the frigid conditions of the Neoproterozoic, rainfall became rare. With volcanoes churning out carbon dioxide and little or no rainfall to weather rocks and consume the greenhouse gas, temperatures climbed.
right on, and it means that humanity's influence on the planet, no matter what nuclear war some idiots would run,
is/would be on the over all planets evolutional process and well being a Non Important Line in the thick book about all.
We are unimportant to it, as humanity, we are just not smart enough to understand it.
Our time on this planet is just a lil eyeblink of the whole Plan, if we are gone a thousand years earlier or later, make's to the whole thing not the slightest difference, sure then not worth to be given a single line in the book of the planet's evolution.
So I continue to breed my cattle and wild porks, and I allow them to fart as much as I do myself,
that's part of the precious and valuable very little time I have myself on the same planet.
To kill my Cattle would safe humanity not a single second of it's unimportant very short whiled existance.
hence I have a nice piece of healthy non gene manipulated home grown beef on the grill right now here on the Finca,
while outside the first real rain of this year is coming down and very welcome.
We will have this year sadly a very dry spring and summer, cattle and others dying due missing water and green grass, no summer tropical storms or hurricanes will be capable to safe any and for us humans here there can be expected a lot this coming season.
But again, that's the rhytm of the planet, we have that every few years and we humans can not do sh..t about any change of it.
