How Ice Ages Happen: The Milankovitch Cycles

I made a follow up to this video explaining more: • The Milankovitch Cycle...
Many people are confused in thinking this has something to do with the global warming debate. This explains how the climate changes naturally over hundreds of thousands of years and is unrelated to any changes over the past century. Please see my follow up video.
The Milankovitch Cycles are changes in the Earth's orbit and rotation that cause the Earth's climate to change over hundreds of thousands of years.

[@rschiwal]

Did you ever consider where we would be without global warming? The early 19th century was the coldest period since the end of the last Ice age. A single volcanic eruption was enough to bring a year without summer. This "mini Ice Age" was actually part of the shift back into the next ice age. It was reversed by the Industrial Revolution. Following the Milankovitch Cycle, we should already be plummeting into the next Ice age. Yes. Global warming is real, and THANK GOD.

The effects of the solar maximum and minimums, grand solar minimum in particular, and the effects of volcanic eruptions, especially those like the Toba eruption in Indonesia 74k years ago, and eruptions like Yellowstone, would have a major impact, but even eruptions like Mt.St . Helens and Mt Pinatubo had recently recorded effects on a global scale. Krakatoa was another major one that produced "the year without a summer". Grand Solar Minimum like the Maunder Minimum that produced the "Little Ice Age" between the 17th and 18th centuries should be considered too. This is an excellent explanation of yet another major factor in the natural, uncontrollable cycle of climate. Great video!

[@kathyyoung1774]

Adam Davis Good summary!

[@JDGage]

Volcanism is one of the main contributing factors to our Earth’s change. It is heating up, no one can deny that. But it is all guessing games as to why. Humans may be the factor, even though I saw a recent study that we only contribute 3% of co2 into the air which only makes up a total of 0.4% of all the gases that make up our atmosphere. But to me this scares me even more to think that humans actually have very little effect on our planet and that Earth is changing rapidly with or without us here. Then the question is left in answered, what is effecting this planet? Is it actually us? Is it the sun changing too? Is it some unknown thing in space like the theorized Planet X? Who knows.

But let’s all point our fingers at conservatives and republicans because it is them who are killing the planet. So let’s put them in prison and stop driving cars and planes, all for 0.4% of our contribution. Either way our planet is changing, and it was going to with or without us here.

Because of the its magnitude. These natural cycles take centuries and centuries to occur; what humans have done in a little over a century is unprecedented and absolutely dwarfs these cycles. Secondly, in these natural cycles, a small temperature change causes a small change in CO2, which builds up to starting/ending ice ages. Man caused climate change is the opposite - we've dumped gigatons of CO2 in to the air and this is causing the warming we're seeing. However, the earth is a giant system.

The Milankovitch Cycles started about 3 million years ago, and are still happening. We have been in an ice age for 15 to 20 million years, since the re-glaciation of Antarctica. People tend to call Glaciation Periods "Ice Ages", but they are just fluctuations within the current ice age. We currently have ice caps on both poles, definitely in an ice age, right now. We are at the top, or warm part of a Milankovitch cycle, called an Inter-glacial Period. It gets warm for 10,000 - 20,000 yrs or so, and then the cycle gets cold for 100,000 yrs. The cycles used to be much shorter and less extreme in temperature change, and had 40,000 yrs of cold. Now it is about a 100,000 yrs of cold.

Luckily for us, the cycles happen "slowly" (in terms of human activity), giving us time to develop ways to control and use fire, build efficient shelters, successfully grow plants in artificial environments and accurately predict when the next cycle will begin.

[@yougotrickrolled8]

Each glacial period is subject to positive feedback which makes it more severe, and negative feedback which mitigates and (in all cases so far) eventually ends it. The causes of ice ages are not fully understood for either the large-scale ice age periods or the smaller ebb and flow of glacial-interglacial periods within an ice age. The consensus is that several factors are important: atmospheric composition, such as the concentrations of carbon dioxide and methane (the specific levels of the previously mentioned gases are now able to be seen with the new ice core samples from the European Project for Ice Coring in Antarctica (EPICA) Dome C in Antarctica over the past 800,000 years); changes in Earth's orbit around the Sun known as Milankovitch cycles; the motion of tectonic plates resulting in changes in the relative location and amount of continental and oceanic crust on Earth's surface, which affect wind and ocean currents; variations in solar output; the orbital dynamics of the Earth-Moon system; the impact of relatively large meteorites and volcanism including eruptions of supervolcanoes.[58][citation needed] Some of these factors influence each other. For example, changes in Earth's atmospheric composition (especially the concentrations of greenhouse gases) may alter the climate, while climate change itself can change the atmospheric composition (for example by changing the rate at which weathering removes CO2). Maureen Raymo, William Ruddiman and others propose that the Tibetan and Colorado Plateaus are immense CO2 "scrubbers" with a capacity to remove enough CO2 from the global atmosphere to be a significant causal factor of the 40 million year Cenozoic Cooling trend. They further claim that approximately half of their uplift (and CO2 "scrubbing" capacity) occurred in the past 10 million years.[59][60] Ice sheets that form during glaciations erode the land beneath them. This can reduce the land area above sea level and thus diminish the amount of space on which ice sheets can form. This mitigates the albedo feedback, as does the rise in sea level that accompanies the reduced area of ice sheets, since open ocean has a lower albedo than land.[55] Another negative feedback mechanism is the increased aridity occurring with glacial maxima, which reduces the precipitation available to maintain glaciation. The glacial retreat induced by this or any other process can be amplified by similar inverse positive feedbacks as for glacial advances.[56] According to research published in Nature Geoscience, human emissions of carbon dioxide (CO2) will defer the next glacial period. Researchers used data on Earth's orbit to find the historical warm interglacial period that looks most like the current one and from this have predicted that the next glacial period would usually begin within 1,500 years. They go on to predict that emissions have been so high that it will not.[57] An important form of feedback is provided by Earth's albedo, which is how much of the sun's energy is reflected rather than absorbed by Earth. Ice and snow increase Earth's albedo, while forests reduce its albedo. When the air temperature decreases, ice and snow fields grow, and they reduce forest cover. This continues until competition with a negative feedback mechanism forces the system to an equilibrium. One theory is that when glaciers form, two things happen: the ice grinds rocks into dust, and the land becomes dry and arid. This allows winds to transport iron rich dust into the open ocean, where it acts as a fertilizer that causes massive algal blooms that pulls large amounts of CO2 out of the atmosphere. This in turn makes it even colder and causes the glaciers to grow more.[50] In 1956, Ewing and Donn[51] hypothesized that an ice-free Arctic Ocean leads to increased snowfall at high latitudes. When low-temperature ice covers the Arctic Ocean there is little evaporation or sublimation and the polar regions are quite dry in terms of precipitation, comparable to the amount found in mid-latitude deserts. This low precipitation allows high-latitude snowfalls to melt during the summer. An ice-free Arctic Ocean absorbs solar radiation during the long summer days, and evaporates more water into the Arctic atmosphere. With higher precipitation, portions of this snow may not melt during the summer and so glacial ice can form at lower altitudes and more southerly latitudes, reducing the temperatures over land by increased albedo as noted above. Furthermore, under this hypothesis the lack of oceanic pack ice allows increased exchange of waters between the Arctic and the North Atlantic Oceans, warming the Arctic and cooling the North Atlantic. (Current projected consequences of global warming include a brief ice-free Arctic Ocean period by 2050.) Additional fresh water flowing into the North Atlantic during a warming cycle may also reduce the global ocean water circulation. Such a reduction (by reducing the effects of the Gulf Stream) would have a cooling effect on northern Europe, which in turn would lead to increased low-latitude snow retention during the summer.[52][53][54] It has also been suggested[by whom?] that during an extensive glacial, glaciers may move through the Gulf of Saint Lawrence, extending into the North Atlantic Ocean far enough to block the Gulf Stream. There is evidence that greenhouse gas levels fell at the start of ice ages and rose during the retreat of the ice sheets, but it is difficult to establish cause and effect (see the notes above on the role of weathering). Greenhouse gas levels may also have been affected by other factors which have been proposed as causes of ice ages, such as the movement of continents and volcanism. The Snowball Earth hypothesis maintains that the severe freezing in the late Proterozoic was ended by an increase in CO2 levels in the atmosphere, mainly from volcanoes, and some supporters of Snowball Earth argue that it was caused in the first place by a reduction in atmospheric CO2. The hypothesis also warns of future Snowball Earths. In 2009, further evidence was provided that changes in solar insolation provide the initial trigger for Earth to warm after an Ice Age, with secondary factors like increases in greenhouse gases accounting for the magnitude of the change.[61]
