Kenneth Richard at NoTricksZone<\/a> reports on yet another paper that shows things were much hotter back in the early Holocene when there were hardly any coal fired power plants, and cars were just molecules spread across hematite deposits, emitting nothing.<\/p>\n\n\n\n

Awkwardly, carbon dioxide levels were very low during this five thousand year Monster Heatwave, so climate modelers are forever trying to erase the hot Holocene, it\u2019s just that the dang evidence keeps turning up in the damnedest of places.<\/p>\n\n\n\n

In 2002 construction workers in Taipei dug up a giant oyster shell, and a whole oyster reef, rather improbably in the metropolitan area. This was 20 kilometers from the ocean where oysters are not supposed to grow.<\/p>\n\n\n\n

One particular oyster shell was especially hard to ignore because it was a 42cm across. When it was carbon-14 dated, it clocked in as 7,500 years old. This particular kind of oyster is not found around Taipei any more (even in the ocean), but is found in colder waters around Japan and Korea. So the researchers wondered if this meant the oceans were somehow improbably higher but cooler<\/em> at the time. They also wanted to find out if these oysters died out in Taipei because of global warming.  Instead it turns out the ocean there was much warmer and quite a lot higher.<\/p>\n\n\n\n

So they sampled the heck out of this shell. They took so many data points they could figure out the seasonal swings from four years in a row in what was somewhere around 5,500 BC. Somehow even when CO2 levels were perfect, the water temperature swings around quite a lot. Neolithic people probably prayed for better weather, rolled some runes or read some tea leaves. These were early climate models and five thousand years later, seasonal models have not improved much.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Given that these oysters like to live 1 to 3m below the surface, the seas then must have been 1 to 3 meters above where they are now. Which gives us that awkward truth, yet again, that everywhere we look 7,000 years ago the seas were 1 \u2013 2 meters higher than where they are today. Our seas are only rising at 1mm a year, (or 3mm if you believe the adjusted satellites).  How could that be unless the natural world was much hotter, frying and expanding the oceans and melting the ice caps to some degree?<\/p>\n\n\n\n

And indeed, current winter water temperatures around Taipei on our Catastrophe-Earth  are 14\u201316o<\/sup>C but back 7,500 years ago researchers suggest the water in winter ranged from 15 to a shocking 23o<\/sup>C.<\/p>\n\n\n\n

And if you\u2019re wondering, the big oyster shell was not just carried there by some fisherman long ago \u2014 it was found in a  muddy black silt clay layer that was more than 5-m thick and filled with other marine remnants above and below that. The researchers dated other things in that stack going back to about 10,000 years ago.<\/p>\n\n\n\n

The researchers concluded as drily as possible \u201cThe disappearance of this type of oyster in Taiwan during the late Holocene should not be due to a warming trend.\u201d<\/p>\n\n\n\n

Indeed.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

So yet again, we find something made the Earth a lot hotter 7,000 years ago, and yet the corals survived, the koalas managed and the extinction apocalypse never came. Sensible people would stop throwing money at the wind to control these natural swings that we can\u2019t predict.<\/p>\n\n\n\n
