White House Halted Ukraine Aid 91 Minutes After Trump & Zelensky Phone Call

Dec 23, 2019

The Pentagon has released new emails revealing how the White House budget office ordered the Pentagon to halt all military aid to Ukraine only 91 minutes after President Trump’s July 25 telephone call with Ukrainian President Volodymyr Zelensky. The heavily redacted emails show senior budget official Michael Duffey telling Pentagon officials Trump had become personally interested in aid and had ordered the hold. The emails were released after the Center for Public Integrity filed a Freedom of Information Act request. Over the weekend, Democratic lawmakers renewed demands for witnesses, including Michael Duffey, to testify at Trump’s Senate impeachment trial. This is Senate Minority Leader Chuck Schumer.

Sen. Chuck Schumer: “If there was ever an argument that we need Mr. Duffey to come testify, this is that information. This email is explosive. A top administration official, one that we requested, is saying, ‘Stop the aid,’ 91 minutes after Trump called Zelensky, and said, ‘Keep it hush-hush.’ What more do you need to request a witness?”

Venice’s Lagoon city hit by another exceptional high tide

Another high tide has hit Lagoon city, just a month after the old city was devastated by its worst flooding in half a century. Although Monday’s tide peaked lower than expected, it remained above the 1.4-meter mark, which is considered exceptional.

Thanks to Carl Davidson for the website! God, this took forever to make. Started: January 2, 2015 Ended: April 20, 2015 I thought that I’d compile the entire history of Earth’s continents (as best as I could).

The Last Four Glacial Cycles

Tobias Friedrich

Feb 21, 2014

During the last 400,000 years, considerable parts of North America, Europe and Asia were covered by large ice-sheets. At the maximum of the glaciation about 21,000 years before present the sea level was approximately 120 m (394 ft) lower than today due to the large quantities of water locked in the ice-sheets, and surface temperatures in many regions of the Earth were significantly colder. The animation shows the extent of the continental ice-sheets and of sea-ice as well as the distribution of land and ocean that is altered by changes in sea-level. A truly satisfactory explanation of the dynamics of glacial cycles remains elusive to this day. Even though there is compelling evidence that changes in the strength and distribution of solar insolation caused by variations in the Earth’s orbit around the sun are mainly responsible for the build-up and melting of ice-sheets. However, the way in which these variations interact with e.g. winds, ocean currents and the terrestrial and marine biosphere is still a matter of current research.

The Search for Life in Space Documentary – Where is the Centre of the Universe


Touch Your Heart
23 Dec. 2019

There is no centre of the universe! According to the standard theories of cosmology, the universe started with a “Big Bang” about 14 thousand million years ago and has been expanding ever since. Yet there is no centre to the expansion; it is the same everywhere. On a clear, moonless night, one can often see a hazy, luminous band stretching across the sky. The ancients devised many fanciful myths to account for this “milky way.” Galileo was the first to look at this haze with a telescope and discover that it was composed of countless dim stars. Today, we realize that this hazy band is our view from the inside of a vast disk that is home to billions of stars, including our own Sun, and vast amounts of interstellar dust. This is our galaxy — the Milky Way. Earlier in this century, Edwin Hubble’s observations led to the discovery that ours is only one of many billions of galaxies that dot the universe with each galaxy home to billions of stars. Some, like the Milky Way, are flat disks with arcing spiral arms and regions of dense interstellar gas, called nebulae, which are active sites of star formation. Yet others are ellipse-shaped agglomerations of mature stars, virtually devoid of interstellar gas or dust.

How Ice Ages Happen: The Milankovitch Cycles


It’s Just Astronomical!

Jun 15, 2019

I made a follow up to this video explaining more: https://www.youtube.com/watch?v=eB3DJ…

This video does not challenge the fact that CO2 causes climate change. This video is about the Milankovitch cycles which are only one of many factors influencing climate. The Milankovitch cycles are important over long very long periods of time: tens of thousands of years. It has little effect over decades or centuries. There is strong evidence that C02 and other greenhouse gases powerful affect our climate.

The Milankovitch Cycles are changes in the Earth’s orbit and rotation that cause the Earth’s climate to change over hundreds of thousands of years.

For more information, I recommend Dan Britt’s lecture on the history of climate: https://www.youtube.com/watch?v=Yze1Y…

The Best Gift of All: A Box of Moon Soil

NASA Goddard

Dec 23, 2019

Astrochemist Jamie Elsila, at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, unwraps pristine Moon soil. Apollo 17 astronauts collected it in 1972 by driving tubes down to 10.6 inches (27 centimeters) below the Moon’s surface and pulling out soil that they vacuum-sealed inside the tube right on the Moon. That tube had never been opened … until recently.

In this video, Elsila and her colleague, Goddard planetary scientist Danielle Simkus, are preparing 2 grams of Moon soil, which is called regolith, for analysis in their lab, the Astrobiology Analytical Laboratory. Besides Moon soil, the scientists are also preparing lab-made Earth soil that will serve as a control in their experiments, helping increase the reliability of the results.

The soils are first crushed with a mortar and pestle and transferred to glass capsules. Then, scientists add water, flame-seal the capsules, and cook them in a special oven to extract organic compounds. Over the next few months, they will study the extracted compounds to shed light on the primordial chemistry of the solar system.

Who Will Tell The People? : The Betrayal Of American Democracy: William Greider

 

Who Will Tell the People is a passionate, eye-opening challenge to American democracy. Here is a tough-minded exploration of why we’re in trouble, starting with the basic issues of who gets heard, who gets ignored, and why. Greider shows us the realities of power in Washington today, uncovering the hidden relationships that link politicians with corporations and the rich, and that subvert the needs of ordinary citizens.

How do we put meaning back into public life? Greider shares the stories of some citizens who have managed to crack Washington’s “Grand Bazaar” of influence peddling as he reveals the structures designed to thwart them. Without naiveté or cynicism, Greider shows us how the system can still be made to work for the people, and delineates the lines of battle in the struggle to save democracy. By showing us the reality of how the political decisions that shape our lives are made, William Greider explains how we can begin to take control once more.
