HOW EARTH MADE US – WATER ~ A MUST SEE VIDEO!!!

HOW EARTH MADE US_WATER

How Earth Made Us – The untold story of history.

This is part 2 in Professor Iain Stewart’s series, “How Earth Made Us”.  I highly recommend you take an hour to watch it as it is superlative!!!

Our planet has amazing power, and yet that’s rarely mentioned in our history books. This series tells the story of how the Earth has influenced human history, from the dawn of civilisation to the modern industrial age. It reveals for the first time on television how geology, geography and climate have been a far more powerful influence on the human story than has previously been acknowledged. A combination of epic story telling, visually stunning camerawork, extraordinary locations and passionate presenting combine to form a highly original version of human history.

Youtube video, “How Earth Made Us – Water”, uploaded on May 16, 2011 – Of all our planet’s forces perhaps none has greater power over us than water.  For me water is the most magical force on earth.  The presence of water shapes, renews and nourishes our planet.  It’s our planet’s life blood, that pumps through it continuously…

Water

This time he explores our complex relationship with water. Visiting spectacular locations in Iceland, the Middle East and India, Iain shows how control over water has been central to human existence. He takes a precarious flight in a motorised paraglider to experience the cycle of freshwater that we depend on, discovers how villagers in the foothills of the Himalayas have built a living bridge to cope with the monsoon, and visits Egypt to reveal the secret of the pharaohs’ success. Throughout history, success has depended on our ability to adapt to and control constantly shifting sources of water.

Discover why societies have succeeded or failed, and how the environment has influenced every aspect of our history from art to industry, religion to war, world domination or collapse. Visiting some of the most iconic places on Earth, How Earth Made Us overturns preconceptions about our civilisations and our cultures to offer a new perspective on who we are today.

‘Grand Canyon’ of Greenland Discovered Under Ice Sheet

GREENLAND

The age of discovery isn’t over yet. A colossal canyon, the longest on Earth, has just been found under Greenland’s ice sheet, scientists announced today (Aug. 29) in the journal Science.

The following reblog is from counselheal.com’s article by Cheri Cheng ~ In an accidental find, researchers identified a huge canyon underneath Greenland’s thick ice sheet. This canyon is roughly twice as long as the Grand Canyon in Arizona. The newly discovered canyon is believed to be 800km or 497 miles long and 800m or half mile deep. It is encased under the ice and carved out by a great river.

GREENLAND TOPOGRAPHIC“With satellite images instantly available on a mobile phone we could assume that the Earth has been fully mapped, but there’s clearly a lot left to discover. We’re incredibly excited about this – it really is a once-in-a-lifetime discovery to find something on this scale,” the lead author, Professor Jonathan Bamber of Bristol University said according to BBC News.

The researchers came across the canyon as they were studying climate changes in the ice sheet. The researchers were interested in finding out how global warming will affect the melting of the ice sheet. Over the past years, central Greenland was 500m or 0.3 miles above sea level. Now, central Greenland is 200m or 0.1 miles above sea level, a drastic change. Upon doing their research, the team used radar to bounce off signals from the bedrock beneath the ice sheet, which is currently two miles thick. By using certain frequencies, the researchers knew that the ice sheet would be transparent to radio waves. With the help of previous research from NASA and from research out of the United Kingdom and Germany, the team found the canyon.

 PETERMANN GLACIER“The Greenland and Antarctic ice sheets hide a lot. It’s pretty surprising to find this canyon. Greenland isn’t that big for a canyon of that size and for it to survive in its pre-glacial form after successive glaciations is quite something,” Professor David Vaughan from British Antarctic Survey said. “There’s likely to be some sort of bacteria down there – whether it’s viable is a different matter.”

The researchers believe that the canyon existed before the ice sheet developed. They also theorized that parts of the canyon might have been visible 100,000 years ago. The canyon currently runs through the center of Greenland and up to the northern coastline. It runs “downhill” and the water from the ice sheet trickles out slowly by the northern end.

This new find is extremely exciting. The canyon is believed to be one of the largest ones in the world. The report was published in Science.
