Predicted spread of humans around the world

This animated video, produced by the University of Hawaii, shows the spread of the human race across the globe over a 125,000 year period. Earth wobbles on its axis, causing major climate shifts. Some of those shifts turned the Arabian Peninsula into lush grassland that ancient humans could have traversed as they migrated out of Africa. Researchers at the University of Hawaii at Manoa simulated climate conditions over the last 125,000 years and predicted how those changes would have allowed humans to spread around the globe (increasing intensity of red shows greater predicted migration).

The world’s most dangerous volcano ?

Say the word “supervolcano” and you’ll immediately think of Yellowstone and its violent past – but what about its future? When will the next super-eruption be? The thing is, this is far from the only supervolcano on Earth, and many of them could easily rival the power of Wyoming’s own. So where are these supervolcanoes and which one of them really is the most dangerous in the world?

  
Let’s take a look, .................

Antarctica A86 Iceberg is now free

A one trillion tonne iceberg – one of the biggest ever recorded - has calved away from the Larsen C Ice Shelf in Antarctica. 

The calving occurred sometime between Monday 10th July and Wednesday 12th July 2017, when a 5,800 square km section of Larsen C finally broke away.
The iceberg, which is likely to be named A68, weighs more than a trillion tonnes. Its volume is twice that of Lake Erie, one of the Great Lakes.

Sea level rise and the Dutch approach

In the waterlogged Netherlands, climate change is considered neither a hypothetical nor a drag on the economy. Instead, it’s an opportunity. 


No place in Europe is under greater threat than this waterlogged country on the edge of the Continent. Much of the nation sits below sea level and is gradually sinking. Now climate change brings the prospect of rising tides and fiercer storms. From a Dutch mind-set, climate change is not a hypothetical or a drag on the economy, but an opportunity.

Earhquake near Lesbos

A strong magnitude 6.3 earthquake off the western coast of Turkey and between the Greek islands of Lesbos and Chinos shook buildings from the Aegean Turkish province of Izmir to the Greek capital of Athens. 


The quake was centered in the Aegean Sea about nine miles south of Lesbos, an area that was on the front line of the migrant influx two years ago. It had a magnitude of 6.1, according to the Geodynamic Institute at the National Observatory of Athens. The quake struck about 3:30 Monday afternoon, local time, and was felt in neighboring Turkey, although no injuries were reported there.

Mount St Helens 37 years ago

Last week it was 37 years ago the Mount Saint Helens in the US erupted


13387_1050561328305761_5834256262935619237_n

On May 18, 1980 a major volcanic eruption occurred at Mount St. Helens, a volcano located in the state of Washington, United States. The eruption (a VEI 5 event) was the only significant one to occur in the contiguous 48 U.S. states since the 1915 eruption of Lassen Peak in California.The eruption was preceded by a two-month series of earthquakes and steam-venting episodes, caused by an injection of magma at shallow depth below the volcano that created a huge bulge and a fracture system on the mountain's north slope.

The new silk road

After some tests with a freight train from China to London a new freight service has started between China and the UK.

A few months ago already the first new silk road trains arrived in Germany
In the end of april the East Wind train pulled up at its destination at just after 1pm, following a 16-day journey, to become the first direct freight train linking China and the United Kingdom. Centuries ago this route was known as the Silk Road. the route along which trade first flourished between China and Europe, bringing silks, spices, Chinese porcelain and even gunpowder from the east.

Re-inhabitation of Small Town America

A lot of small villages in the USA didn't grow for more than 50 years. They became forgotten Small Towns, Shitvilles.....However they are now discovered by people from the large cities. Waterville, Mississippi is a nice example.


Less than a decade ago, Water Valley, Mississippi was a forgotten small town: there were 18 empty storefronts lining it’s four-block Main Street and plenty of decaying homes for sale. Located only twenty miles from the University of Mississippi and the pricey town of Oxford , it was well-placed for revival.
 In 2002, the first new inhabitants came from Oxford. They were early pioneers in the effort to rehabilitate the old 19th Century railroad town- turning their former drugstore into the Bozarts art gallery, but it took the formation of a community to create real change.
Water Valley is 3,500 people with a four-block long downtown. Since 2002 the  team has been instrumental in bringing 88 new jobs to downtown. Adding 26 new businesses. Fixing buildings, more major renovations in 29 buildings. Adding 14 upper floor apartments. In that new business mix they have added four new restaurants, three art galleries, one grocery store, one doctor’s office and one brewery.”

Solar Power world leaders

China is now the largest producer of solar energy in the world. But neighbouring India is no less ambitious when it comes to renewable energy. The country has just put the world’s largest solar power plant into service. The Adani Group’s new site in the southern Indian state of Tamil Nadu covers an area of 10 square kilometers and has a capacity of 648 megawatts (MW). This is nearly 100 MW more than the previous record-holder, the Topaz Solar Farm in California.

Geological Brexit

The UK has now started the formal process of leaving the EU, but scientists say they have evidence of a much earlier "Brexit".

 
They have worked out how a thin strip of land that once connected ancient Britain to Europe was destroyed. The researchers believe a large lake overflowed 450,000 years ago, damaging the land link, then a later flood fully opened the Dover Strait.

Northern California: Before and after 2017 storms

January 18, 2014: January 2014 was one of the driest Januarys on record in recorded history. Even in winter, much of the vegetation in drought-stricken California appeared brown. Roughly two weeks after this photo was taken, the Sierra snowpack was measured on Feb. 1 at 9 percent of average, the lowest ever for that time of year.

March 1, 2017: After a series of storms slam Northern California throughout January and February, the vegetation greens and the snowpack is at 185 percent of normal.

A new continent: Zealandia

Geologists claim to have discovered a new continent to the east of Australia: Zealandia. At 4.9 million square kilometres of land mass, 94 per cent of which is under water, Zealandia would be the world's smallest continent.

In a paper published in the Geological Society of America's Journal, researchers explain that Zealandia measures five million sq km (1.9m sq miles) which is about two thirds of neighbouring Australia.

Volcano under naples

The Campi Flegrei caldera under the Italian city of Naples shows signs of “reawakening” after almost 500 years of inactivity.  So what's happening underneath Naples ?



According to a study published Tuesday, it is close to nearing a critical pressure point, which could spell disaster for the 500,000 people that reside in the area. The 12km-wide cauldron is actually a collapsed volcano. As such it does not have one obvious central peak, rather it is fuelled by one huge magma chamber. This is precisely what makes Campi Flegrei so dangerous. Italian and French scientists have for the first time identified a threshold beyond which rising magma under the Earth’s surface could trigger the release of fluids and gases at a 10-fold increased rate.

Mount Etna prognoses 2017

Etna in Italy had a real quiet 2016. However, it appears that 2017 won’t follow the same path. Since January 23, the summit craters on Etna have been restless and now strombolian explosions have been rocking the South East Crater. In fact, two distinct vapor-and-ash plumes are active on the Sicilian volcano. This is the first sign of magma at the surface at Etna in over eight months (which is a long time for the nearly-constantly restless volcano).

Boundaries, Borders, and… The Trump Wall?

We have all heard it: “I will build a great wall – and nobody builds walls better than me, believe me – and I’ll build them very inexpensively – I will build a great, great wall on our southern border, and I will make Mexico pay for that wall. Mark my words.” Trump’s words from 2015 are once again making headlines and the proposed wall is forcing society to pose some tough questions. Are walls a knee-jerk protectionist response? How is globalisation implicated? Do walls work?

Eruption of the Colima

On 19th of january the Colima volcano erupted again. The volcano,located in  Mexico, shot ash and smoke over 6,500 feet into the air and could be heard 50 miles away, officials said. 

The eruption Wednesday on the 12,000-foot mountain was the third major eruption this year, although the Volcanic Ash Advisory Center in Washington, D.C., part of the National Oceanographic and Atmospheric Administration, gave almost daily accounts of new ash in the atmosphere since Jan. 3, as well as a spectacular eruption on Dec. 27. The mountain, one of 14 active volcanoes in Mexico, is on the country's west coast, between Colima and Jalisco states, 300 miles west of the capital, Mexico City.

Bogoslof Volcano: 31,000 feet ash cloud

An Alaska volcano active since mid-December has erupted again. Bogoslof Volcano in the Aleutian Islands erupted last week on wednesday and sent up an ash cloud estimated at 31,000 feet. The Alaska Volcano Observatory raised the aviation threat code to red, the highest level. Ash clouds higher than 20,000 feet are a threat to intercontinental jet aircraft because ash can damage engines.

 

On December 14, 1989, Redoubt volcano, also in Cook Inlet, erupted. The next day, KLM flight 867, carrying 231 passengers from Amsterdam to Tokyo with a stop in Anchorage, flew through a Redoubt ash plume, causing all four engines to fail. The aircraft dropped more than 3 km (2 mi) in altitude within five minutes before the flight crew managed to restart the engines and land the plane safely in Anchorage. All four engines on the aircraft had to be replaced, with damages totaling about $80 million. The Redoubt eruption continued through early June 1990.
