We are currently in an Interglaciar Period within the Holocene and in a global warming trend lead by the higher latitudes of the Northern Hemisphere.
Aside from geographic changes, enhanced by the techtonic plates, ocean currents or sudden events such as asteroid impacts, massive vulcanism activity or variation in atmospheric composition & Others, the main driver, the one that seems to dictate when we have Interglaciar either Glaciar periods are Milankovitch Cycles.
My understanding of the Milankovitch Cycles is rather scarce. I know that eccentricity, axial tilt and precession are involved.
The questions are:
1. There must be a high or less degree of eccentricity to develop an Ice Age?
2. Do glaciers grow at both Hemispheres simultaneously? By what I have read, tilt oscillates between 21-24°. When it is closer to 21°, even if this variation does not seem extreme, higher latitudes receive far less sunlight.
But, in a "high eccentric" orbit and a 24° axial tilt let's say, would not it create optimal conditions to start building up Ice caps, glaciers and sea ice in just one of the two Hemispheres?
I still have a lot of doubts about how this works and fits, so I would appreciate someone to help me out in order to improve my knowledge in what I consider to be the main natural driver of the Climate.
I would also request for pages with data of axial tilt&precession&eccentricity, whether I can find a webpage with constantly updated data of these there.
Thanks in advance
