I got interested, Googled a lot and wrote a separate post <a href=\"https:\/\/stuif.com\/blog\/?p=28703\">Ice Ages<\/a>.  Here is a summary.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In the 4.5 billion years of its existence, Earth has been mostly  (~85%) a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Greenhouse_and_icehouse_Earth#Greenhouse_Earth\">Greenhouse<\/a>, no icecaps, icesheets, glaciers. But there have also been at least five major periods that Earth was an <a href=\"https:\/\/en.wikipedia.org\/wiki\/Greenhouse_and_icehouse_Earth#Icehouse_Earth\">Icehouse<\/a>, partially covered with ice. These Icehouse periods are called Ice Ages. At this time Earth is in the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Late_Cenozoic_Ice_Age\">Late Cenozoic Ice Age<\/a>, which started 34 million years ago.<\/li>\n\n\n\n<li>In an Ice Age there is always permanent ice, but the amount fluctuates. There are periods that the ice advances, they are called <a href=\"https:\/\/en.wikipedia.org\/wiki\/Glacial_period\">glacials<\/a>. And there are periods that the ice retracts, called <a href=\"https:\/\/en.wikipedia.org\/wiki\/Interglacial\">interglacials<\/a>. <\/li>\n\n\n\n<li>The last glacial was about 21.000 years ago and is often called the (Last) Ice Age. At the moment we are living in an interglacial, icecaps, icesheets, glaciers are retracting.  But Earth is still an Icehouse.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">There have been numerous glacials and interglacials in those 34 million years.  Here the global temperatures for the latest are shown. Notice that the timescale is from right to left, so the last glacial (&#8220;the Ice Age&#8221;) is the rightmost snowflake.  And there is an obvious regularity with a period of roughly 100.000 year.  If you want to know more about the theory, read the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Milankovitch_cycles\">Milankovitch Cycles<\/a> article in Wikipedia.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-2 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/glacials-interglacials.png\"><img loading=\"lazy\" decoding=\"async\" width=\"702\" height=\"422\" data-attachment-id=\"28944\" data-permalink=\"https:\/\/stuif.com\/blog\/?attachment_id=28944\" data-orig-file=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/glacials-interglacials.png\" data-orig-size=\"702,422\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"glacials-interglacials\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/glacials-interglacials-300x180.png\" data-large-file=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/glacials-interglacials.png\" tabindex=\"0\" role=\"button\" data-id=\"28944\" src=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/glacials-interglacials.png\" alt=\"\" class=\"wp-image-28944\" srcset=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/glacials-interglacials.png 702w, https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/glacials-interglacials-300x180.png 300w, https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/glacials-interglacials-500x300.png 500w\" sizes=\"auto, (max-width: 702px) 100vw, 702px\" \/><\/a><\/figure>\n<\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">In this blog we are especially interested in sea levels.  During a glacial a lot of water is frozen in icecaps, icesheets and glaciers, so the sea level drops, and during an interglacial  ice melts and the sea level rises. Here are the sea levels during the last 400.000 years. In the original graph time goes from left to right, I  have flipped it to make comparison with the temperature graph easier. Notice the similarity between temperature and sea level.  During interglacials sea levels were about the same as nowadays, but during glacials  they were up to 120 meter lower.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-3 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/sea-levels-flipped.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"385\" data-attachment-id=\"28952\" data-permalink=\"https:\/\/stuif.com\/blog\/?attachment_id=28952\" data-orig-file=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/sea-levels-flipped.jpg\" data-orig-size=\"768,385\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;Picasa&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;1699033838&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"sea-levels-flipped\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/sea-levels-flipped-300x150.jpg\" data-large-file=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/sea-levels-flipped.jpg\" tabindex=\"0\" role=\"button\" data-id=\"28952\" src=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/sea-levels-flipped.jpg\" alt=\"\" class=\"wp-image-28952\" srcset=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/sea-levels-flipped.jpg 768w, https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/sea-levels-flipped-300x150.jpg 300w, https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/sea-levels-flipped-500x251.jpg 500w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><\/a><\/figure>\n<\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">I will now concentrate on the last 150 thousand years, Here is a more detailed temperature graph. Starting from the left, we see the end of the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Penultimate_Glacial_Period\">Penultimate Glacial<\/a> at about 135 thousand year ago. It was a very cold one. Then, relatively quite fast, temperatures are rising, until they reach a maximum  at 125 thousands year ago in the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Eemian\">Eemian Interglacial<\/a>. Warmer than nowadays, sea level 6-9 meter higher (!) than today.  After this maximum, slowly and irregularly , temperatures are dropping, until a new glacial maximum  is reached, about 21 thousand years ago. After this the temperature rises again and we reach the Holocene interglacial in which we are living nowadays.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-4 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/age-of-human-expansion.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"490\" data-attachment-id=\"28963\" data-permalink=\"https:\/\/stuif.com\/blog\/?attachment_id=28963\" data-orig-file=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/age-of-human-expansion.jpg\" data-orig-size=\"1322,632\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"age-of-human-expansion\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/age-of-human-expansion-300x143.jpg\" data-large-file=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/age-of-human-expansion-1024x490.jpg\" tabindex=\"0\" role=\"button\" data-id=\"28963\" src=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/age-of-human-expansion-1024x490.jpg\" alt=\"\n\" class=\"wp-image-28963\" srcset=\"https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/age-of-human-expansion-1024x490.jpg 1024w, https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/age-of-human-expansion-300x143.jpg 300w, https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/age-of-human-expansion-768x367.jpg 768w, https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/age-of-human-expansion-500x239.jpg 500w, https:\/\/stuif.com\/blog\/wp-content\/uploads\/2023\/11\/age-of-human-expansion.jpg 1322w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n<\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This time period is very interesting for homo sapiens.  Indicated are two waves of migration out of Africa.  And about 74.000 year ago the Toba volcano on Sumatra erupted, one of the largest eruptions in Earth&#8217;s history.  Present day Lake Toba is  occupying the caldera of this eruption.  There is a theory that this eruption almost caused the extinction of homo sapiens, but this <a href=\"https:\/\/en.wikipedia.org\/wiki\/Toba_catastrophe_theory\">Toba catastrophe theory<\/a> is something for a separate blog. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We zoom in one more time and  look at the sea level. It was 120 m below present during the last glacial maximum, then rising more or less gradually until it reached present levels around 6000 years ago. Around 12-14 thousand years ago, there was an interruption with a cold period (<a href=\"https:\/\/en.wikipedia.org\/wiki\/Younger_Dryas\">Younger Dryas<\/a>).

Could it be that during this last glacial there was a civilisation in Sundaland, later destroyed by the rising sea levels?  Could that have been the lost continent,  Plato&#8217;s Atlantis?  Or the Garden of Eden?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the last few decades, three books have been published advocating exactly that. In 1999 Stephen Oppenheimer published  <a href=\"http:\/\/Amazon.com(opens in a new tab)amazon.com\/Eden-East-Drowned-Continent-Southeast\/dp\/0753806797\">Eden in the East<\/a>. According to him it was Sundaland where the first human civilisation started. After Sundaland became flooded (Noah&#8217;s flood!), the population dispersed and fertilized the cultures of Mesopotamia, Egypt, China and India. A few years later, in 2005, Arysio Santos published  <a href=\"https:\/\/www.goodreads.com\/en\/book\/show\/3010034\">Atlantis, the lost continent finally found<\/a>.  Santos was convinced that Sundaland was the Garden of Eden and Plato&#8217;s Atlantis. Quite recently, in 2019, Dhani Irwanto published  <a href=\"https:\/\/www.researchgate.net\/publication\/333812211_Tracing_the_Cradle_of_Civilizations_in_Sundaland\">Sundaland: Tracing The Cradle of Civilizations<\/a>.  Same approach. All these books are still for sale at Amazon.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-10 is-layout-flex

But Atlantis, the Garden of Eden, the Cradle of Civilisation? Here is some information about the authors.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Stephen Oppenheimer (1947-) is a British paediatrician and geneticist.  After 1997 he started a new career as a researcher and popular-science writer on human prehistory.<\/li>\n\n\n\n<li>Arysio Santos (1937-2005) was a Brazilian nuclear engineer, but &#8220;his true hobby in life was researching arcane subjects such as Symbolism, Alchemy, the Holy Grail, Comparative Mythology and Religion&#8221; (quote from <a href=\"https:\/\/atlan.org\/about-the-author\/\">his own website<\/a>)<\/li>\n\n\n\n<li>Dhani Irwanto (1962 -) is an Indonesian hydro civil engineer. Founder of Indonesia Hydro Consult in 2010 and its director until now. Became interested in Sundaland and has written books about it.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The authors have in common they have no formal training in the subject matter. They were captivated by the subject and delved into all aspects of it, climatology, geology, linguistics, anthropology etc. Their approach, especially Irwanto&#8217;s, tries to be scientific. But it is still <a href=\"https:\/\/en.wikipedia.org\/wiki\/Fringe_science\">Fringe Science<\/a>,  outside the mainstream discipline. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I was considering to buy Irwanto&#8217;s book, but then I discovered a video <a href=\"https:\/\/youtu.be\/vbzdKxO9W6s\">Tracing the Cradle of Civilisations in Sundaland<\/a>, about a lecture he gave in the Philippines in 2017 at an Asean Advanced Archaeology Symposium. Brilliant presentation, worth watching (28 minutes). <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But he is really going too far in his enthusiasm.  Here is a screenshot from the video.  Everything, all over the world , originated in Sundaland.
