Los Angeles Participates in Innovative Climate Change Experiment


Published on Jul 4, 2013

For decades, scientists have been able to measure air quality and look at its impact on human health. Now, scientists are testing new ways of measuring climate-changing greenhouse gases in the air. Elizabeth Lee reports from Los Angeles, one of the cities that is participating in a new effort called the Megacities Carbon Project.

ON THE LINE: NSA Surveillance Program: International Implications


Published on Jul 5, 2013

The leaks about the US National Security Agency’s secret surveillance program have created an uproar around the world, with some countries demanding an explanation, and others calling it a breach of trust. But U.S. Secretary of State John Kerry says that the surveillance activities in question are not unusual for many nations. This week’s episode of “On the Line” discusses the implications of this program for American diplomacy around the globe.

The Future of Government


Published on Jul 5, 2013

Governments must now address how they are to remain relevant. To do so they must respond to rapidly changing conditions and citizens’ expectations. They also need to build capacity to operate effectively in complex, interdependent national and global networks across the public, private and non-profit spheres. This will necessitate building public-private collaboration at global, regional and national levels — through leadership, dialogue and partnership building.

Why Mars Died, and Earth Lived


Published on Oct 13, 2012

This video explores the most basic question of all: why we explore space? Be sure to experience the visual spectacle in full HD, 1080P.

The Mars rover, Curiosity, is the latest in a long line of missions to Mars: landers sent to scoop its soil and study its rocks, orbiters sent to map its valleys and ridges.

They are all asking the same question. Did liquid water once flow on this dry and dusty world? Did it support life in any form? And are there remnants left to find? The science that comes out of these missions may help answer a much larger, more philosophical question.

Is our planet Earth the norm, in a galaxy run through with life-bearing planets? Or is Earth a rare gem, with a unique make-up and history that allowed it to give rise to living things? On Mars, Curiosity has spotted pebbles and other rocks commonly associated with flowing water.

It found them down stream on what appears to be an ancient river fan, where water flowed down into Gale Crater. This shows that at some point in the past, Mars had an atmosphere, cloudy skies, and liquid water flowing. So what could have turned it into the desolate world we know today?

One process that very likely played a role goes by the unscientific name, “sputtering.” Like the other planets in our solar system, Mars is lashed by high-energy photons from the Sun. When one of these photons enters the atmosphere of a planet, it can crash into a molecule, knocking loose an electron and turning it into an ion. The solar wind brings something else: a giant magnetic field. When part of the field grazes the planet, it can attract ions and launch them out into space.

Another part might fling ions right into the atmosphere at up to a thousand kilometers per second. The ions crash into other molecules, sending them in all directions like balls in a game of pool. Over billions of years, this process could have literally stripped Mars of its atmosphere, especially in the early life of the solar system when the solar wind was more intense than it is today.

Sputtering has actually been spotted directly on another dead planet, Venus. The Venus Express mission found that solar winds are steadily stripping off lighter molecules of hydrogen and oxygen. They escape the planet on the night side… then ride solar breezes on out into space.

This process has left Venus with an atmosphere dominated by carbon dioxide gas… a heat trapping compound that has helped send surface temperatures up to around 400 degrees Celsius. The loss of Venus’ atmosphere likely took place over millions of years, especially during solar outbursts known as coronal mass ejections.

If these massive blast waves stripped Venus and Mars of an atmosphere capable of supporting life how did Earth avoid the same grim fate? We can see the answer as the solar storm approaches earth. Our planet has what Mars and Venus lack – a powerful magnetic field generated deep within its core.

This protective shield deflects many of the high-energy particles launched by the Sun. In fact, that’s just our first line of defense. Much of the solar energy that gets through is reflected back to space by clouds, ice, and snow.

The energy that earth absorbs is just enough to power a remarkable planetary engine: the climate. It’s set in motion by the uneveness of solar heating, due in part to the cycles of day and night, and the seasons. That causes warm, tropical winds to blow toward the poles, and cold polar air toward the equator.

Wind currents drive surface ocean currents. This computer simulation shows the Gulf Stream winding its way along the coast of North America. This great ocean river carries enough heat energy to power the industrial world a hundred times over.

It breaks down in massive whirlpools that spread warm tropical waters over northern seas. Below the surface, they mix with cold deep currents that swirl around undersea ledges and mountains. Earth’s climate engine has countless moving parts: tides and terrain, cross winds and currents — all working to equalize temperatures around the globe.

Over time, earth developed a carbon cycle and an effective means of regulating green house gases. In our galaxy, are still-born worlds like Mars the norm? Or in Earth, has Nature crafted a prototype for its greatest experiment… Life?

Noam Chomsky – The Political Economy of the Mass Media


Published on Apr 1, 2012

Noam Chomsky explains “the Propaganda Model”, the central theme of his book, co-authored with Edward Herman, MANUFACTURING CONSENT: THE POLITICAL ECONOMY OF THE MASS MEDIA. Noam Chomsky spoke at the Wisconsin Union Theater on the Madison campus of the University of Wisconsin on the evening of March 15, 1989. The lecture was sponsored by the Wisconsin Union Directorate’s Distinguished Lecture Series for the 1988-89 academic year.

BBC News – More flood defence spending in England and Wales urged

4 July 2013 Last updated at 07:55 ET

Defra said it was working on long-term projects to protect homes and businesses

By Roger Harrabin Environment analyst
Flood defence spending is still not high enough in England and Wales to combat the risk of water invading people’s homes, MPs have said.

The amount spent on defences should rise by £20m year on year over the next 25 years, the committee of MPs said.

It said spending was not “keeping pace” with the risk of more severe weather.

The Department for Environment, Food and Rural Affairs said that from 2015 it would spend £370m on new UK-wide defences, rising to over £400m in 2021.

Ministers have also reached an agreement with the Association of British Insurers guaranteeing affordable flood insurance for people in high-risk areas.

“Maintenance of these defences and effective dredging of watercourses must be a priority”

Anne McIntosh Chairwoman, environment, food and rural affairs committee

But MPs on the environment, food and rural affairs committee (Efra) said ministers should be attracting much more private funding into defences.

They warned that there was a risk to food production because farmland was not properly protected from rising waters.
