“Severe” Ice Age event could have killed off Neanderthals 39,000 years ago, say experts

Significant interbreeding between Neanderthals and early modern humans had probably already occurred in Asia more than 50,000 years ago, so the dating evidence now indicates that the two populations could have been in some kind of contact with each other for up to 20,000 years, first in Asia then later in Europe.

This may support the idea that some of the changes in Neanderthal and early modern human technology after 60,000 years ago can be attributed to a process of acculturation between these two human groups.

Of course, samples from some sites did not produce dates at all, and the coverage did not extend to eastern regions such as Uzbekistan and Siberia, where Neanderthals are also known to have lived, so it is still possible Neanderthals lingered later in some areas.

But the overall pattern seems clear – the Neanderthals had largely, and perhaps entirely, vanished from their known range by 39,000 years ago.

A severe Heinrich event, characterised by cold and dry conditions, hit Europe between 39-40,000 years ago, and it remains to be seen whether that event delivered the coup de grâce to a Neanderthal population that was already low in numbers and genetic diversity, and trying to cope with economic competition from incoming groups of Homo sapiens.”

The huge storm churning through the atmosphere in Saturn’s northern hemisphere overtakes itself as it encircles the planet in this true-color view from NASA’s Cassini spacecraft.

This picture, captured on Feb. 25, 2011, was taken about 12 weeks after the storm began, and the clouds by this time had formed a tail that wrapped around the planet. Some of the clouds moved south and got caught up in a current that flows to the east (to the right) relative to the storm head. This tail, which appears as slightly blue clouds south and west (left) of the storm head, can be seen encountering the storm head in this view.

This storm is the largest, most intense storm observed on Saturn by NASA’s Voyager or Cassini spacecraft. It is still active today. As scientists have tracked this storm over several months, they have found it covers 500 times the area of the largest of the southern hemisphere storms observed earlier in the Cassini mission (see PIA06197). The shadow cast by Saturn’s rings has a strong seasonal effect, and it is possible that the switch to powerful storms now being located in the northern hemisphere is related to the change of seasons after the planet’s August 2009 equinox.

Hurricanes have been moving towards the Earth’s poles, at a rate of about 30 miles each decade. As the storms move further northwards and southwards, the scientists caution that we could increasingly see hurricanes hit harder and more frequently in areas where the storms were typically sparse. Interestingly, they also note that the same time period has also seen an expansion of the tropics themselves towards the poles, into the areas that have previously been classified as subtropical.

Which is just awesome news if you live in the Southern Archonic Protectorate with its new “Infrastructure Prime Minister” in charge. Except that government is dismantling everything Green and doesn’t recognize or acknowledge the climate threat. So just keep building roads bro. And cutting funding to basic science. Just keep on truckin in a spy way.

I’m sure Melbourne will get hit last its cool bro.

PS – maybe we get our cool Hexagon from this. Nice space marker.

Kiribati is a flyspeck of a United Nations member state, a collection of 33 islands necklaced across the central Pacific. Thirty-two of the islands are low-lying atolls; the 33rd, called Banaba, is a raised coral island that long ago was strip-mined for its seabird-guano-derived phosphates. If scientists are correct, the ocean will swallow most of Kiribati before the end of the century, and perhaps much sooner than that. Water expands as it warms, and the oceans have lately received colossal quantities of melted ice.
A recent study found that the oceans are absorbing heat 15 times faster than they have at any point during the past 10,000 years. Before the rising Pacific drowns these atolls, though, it will infiltrate, and irreversibly poison, their already inadequate supply of fresh water. The apocalypse could come even sooner for Kiribati if violent storms, of the sort that recently destroyed parts of the Philippines, strike its islands.
For all of these reasons, the 103,000 citizens of Kiribati may soon become refugees, perhaps the first mass movement of people fleeing the consequences of global warming rather than war or famine.

This is why Tong visits Fiji so frequently. He is searching for a place to move his people. The government of Kiribati (pronounced KIR-e-bass, the local variant of Gilbert, which is what these islands were called under British rule) recently bought 6,000 acres of land in Fiji for a reported $9.6 million, to the apparent consternation of Fiji’s military rulers. Fiji has expressed no interest in absorbing the I-Kiribati, as the country’s people are known. A former president of Zambia, in south-central Africa, once offered Kiribati’s people land in his country, but then he died. No one else so far has volunteered to organize a rescue.
