The G-20 is meeting this week in Pittsburgh, Pennsylvania. Chaired by President Barack Obama, the purpose of the summit is to, “review the progress made since the Washington and London Summits and discuss further actions to assure a sound and sustainable recovery from the global financial and economic crisis.” I’ve heard of the G-8, but the G-20? I began to wonder about this alphanumeric soup of organizations. Who are they and what are they concerned with? The following scorecard should help interested followers of this subject keep track of the major players.

The G-6: Organized in 1975 by the finance ministers of Germany and France who were frustrated with the formality and structure of larger international meetings, the G-6 and subsequent evolutions of this body are strictly informal bodies that meet to discuss economic issues of mutual interest. After the creation of the G-8, the term G-6 is now used to refer to the six most populous members of the European Union. The member countries are: the United States, United Kingdom, France, Germany, Italy, Japan

The G-7: Formed in 1976, this is an informal forum for the finance members of seven big industrial economies to discuss economic issues and seek agreement. Member countries include: Canada, France, Germany, Italy, Japan, United Kingdom, United States. Now also includes the European Union.

The G-8: An evolution of the G-7, membership grew to include Russia. The European Union is a limited member; it cannot host a meeting or hold the presidency of the body. Members are: Canada, France, Germany, Italy, Japan, United Kingdom, United States, Russia. European Union (limited member)

The G-8 plus Five: Recognizing the growing influence of other countries, the original group sometimes broadens their meetings by including the Outreach Five. As with all meetings, other countries are sometimes invited to attend. Members: Canada, France, Germany, Italy, Japan, United Kingdom, United States, Russia. European Union (limited member) Plus: Brazil, China, India, Mexico, South Africa.

The G-20: According to their website, “[t]he G-20 was created as a response both to the financial crises of the late 1990s and a growing recognition that key emerging-market countries were not adequately included in the core of global economic discussion and governance.” Where the earlier groups (G-6 through G-8) were organized around the industrialized countries of the world, the G-20 begins to bring emerging economies into the dialog. Their first meeting was in Berlin, Germany. The Managing Director of the International Monetary Fund (IMF) and the President of the World Bank, plus the chairs of the International Monetary and Financial Committee and Development Committee of the IMF and World Bank, also participate in G-20 meetings on an ex-officio basis.

The G-20 is made up of the finance ministers and central bank governors of 19 countries: Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Mexico, Russia, Saudi Arabia, South Africa, South Korea, Turkey, United Kingdom, United States, European Central Bank

The G-33: The name for a group of developing countries that coordinates on trade and economic issues. It was created in order to help group countries which were all facing similar problems and give a unified voice to countries that were traditionally excluded from discussions among the industrialized countries. Members: Antigua & Barbuda, Barbados, Belize, Benin, Botswana, China, Côte d’Ivoire, Cuba, Democratic Republic of the Congo, Dominican Republic, El Salvador, Grenada, Guyana, Guatemala, Haiti, Honduras, India, Indonesia, Jamaica, Kenya, Laos, Mauritius, Madagascar, Mongolia, Mozambique, Nicaragua, Nigeria, Pakistan, Panama, Peru, Philippines, St Kitts & Nevis, St Lucia, St Vincent & the Grenadines, Senegal, South Korea, Sri Lanka, Suriname, Tanzania, Trinidad & Tobago, Turkey, Uganda, Zambia and Zimbabwe.

There are other groups variously labeled as G-8, G-20, G-33, and even N-11 (countries which Goldman Sachs considered in 2005 to have a high potential of becoming the world’s largest economies this century: Bangladesh, Egypt, Indonesia, Iran, Mexico, Nigeria, Pakistan, Philippines, South Korea, Turkey and Vietnam).

One of the best, reliable, sources of information about these groups and their members may be found on the websites of the World Trade Organization and the previously mentioned G-20.

Popular vacation destinations are ready to give tourists what they're looking for, all that's missing now are the tourists themselves. Photo: Marvin (PA) (flickr)

Ah, summer. A time of rest, relaxation, meticulously planned vacations ... and this year, less travel.

One June report by a UN body predicted tourism would decline by 4 to 6 percent this year — and that's before the H1N1 virus further dampened travel.

Tourism is down even in the U.S., where tourists spent more money than anywhere else in 2008. But the downturn is worse across the Atlantic, according to an August Reuters story.

On Spain's popular Costa del Sol, tourist traffic is "the worst I have ever seen it," drink seller Pedro Hervas tells The Telegraph. "There is no one on the beach. If you came here last year at this time you would not be able to get around, there would be so many cars and people."

Analysts cited in a Wall Street Journal story on the battered Mediterranean tourism industry conclude that nations have yet to see the real effects of the tourism slump on economic growth.

"We are seeing a multifaceted impact from the crisis on the tourism sector and there will be a variety of consequences," Marko Mrsnik told the Journal. "These include employment consequences, consequences on the creditworthiness of households and companies in the sector and their ability to pay their debts, and it will certainly have an impact on government revenues."

In Greece about 19,000 jobs have been lost, people in the industry told The Wall Street Journal, and economists predict the lack of tourism could cut more than a percentage point off economic growth this year. According to the same Journal article, in Italy private-sector estimates of tourism-related job losses are as high as 150,000.

Some sunlight, however, has seeped through the dreary forecasts. After Iceland's economic meltdown made their currency more affordable, tourism spiked, and has continued to grow through the summer. North African countries such as Morocco and Algeria have also welcomed more visitors. Some of them are undoubtedly vacationing on the other side of the Mediterranean Sea for a change — or rather, to save some change.

A single solar farm in the Sahara desert could provide clean electricity for all of Europe.

Scientists are investigating solar farms in the Sahara, as part of a $62 billion plan to provide all green power for a new, carbon-neutral European super-grid.

Because the sunlight in northern Africa is more intense, solar panels in the Sahara can capture up to three times more energy then panels located in northern Europe.

Arnulf Jaeger-Walden of the European commission’s Institute for Energy said today at the Euroscience Open Forum in Barcelona that a mere 0.3 percent of the light falling on the Sahara and Middle Eastern deserts would supply all the energy Europe needed.

The proposed solar farms will utilize advanced solar technology created by the California-based firm Ausra. These solar power plants use movable reflectors to concentrate sun light on pipes. The water in these pipes is solar-heated to produce high-pressure steam, which then goes through a turbine to generate electricity.

These innovative solar plants store enough hot water to make electricity even at night, and to increase production during peak demand periods. The plants are much more effective than traditional solar panel designs, allowing the plants to generate electricity at a mere 10 cents per kilowatt hour, much less than what the average consumer is paying now.

Ausra’s technology has been made cost-efficient by advances in transportation. Jaeger-Walden explained today that transporting the solar electricity would be relatively easy using new high-voltage direct current transmission (DC) lines instead of the alternating lines currently used. Energy loss using DC lines is very low, making the usual issue of transportation over long distances less of a problem.

Sixty-two million dollars for a project of this kind seems expensive — until you compare it with the more than $45 trillion in green-energy systems the world needs over the next 30 years to avoid global catastrophe, according to the International Energy Agency.

Doug Parr, Greenpeace UK's chief scientist, welcomed the project, saying:

"A large scale renewable energy grid is just the kind of innovation we need if we're going to beat climate change. Europe needs to become a zero-carbon society as soon as possible, and that will only happen with bold new ideas like this one. Tinkering with 20th-century technologies like coal and nuclear simply isn't going to get us there."

No global temperature change for ten years sounds too good to be true.

A new study by German researchers suggests that natural climate cycles will limit temperature increases for the next decade. But don’t forget about global warming yet.

The researchers base these predictions on a computer model they developed after the natural cycle of ocean temperatures called the Atlantic Multidecadal Oscillation (AMO). The AMO is closely linked to currents bringing tropical heat north, and appears to occur every 60 to 70 years.

But researcher Noel Keenlyside expects manmade global warming to raise temperatures to the upper limits of this natural cycle.

The research report emphasized that even if the researchers' model proves correct, the report does not mean global warming and the drastic higher temperatures projected by the Intergovernmental Panel on Climate Change (IPCC) and many other institutions are wrong. After about 15 years, the group expects temperatures to once again rise significantly.

And it's not all about temperature. Another benefit of this new understanding of the AMO is the ability to better predict weather patterns controlled by the currents.

The researchers themselves say that the value of their research is predicting temperature and precipitation for the next ten years with certainty. The economic impact of this information will likely be significant, aiding crop planning, storm preparation, and emergency responses.

This news may help governments to stay on track reducing greenhouse gas emissions, as well as protect citizens from weather catastrophes.

“Every 30 seconds in the United States someone files for bankruptcy in the aftermath of a serious health problem,” according to the National Coalition on Health Care.

The United States spends the most in the world on health care – about $2 trillion annually. Yet, the U.S. ranks 37th in world in terms of the quality and fairness of its health care, according to the World Health Organization (WHO).

The U.S. has no comprehensive national health insurance system. Those who have insurance get it through their employers, government programs, or private suppliers. However,there are 47 million people that are not insured. Furthermore, millions more are underinsured, which has led to a growing epidemic of medical debt and bankruptcy in the United States. A Harvard University report found that about 50 percent of all bankruptcy fillings were partially due medical debt.

In light of this growing problem, correspondent T.R. Reid traveled with Frontline to investigate if other free-market countries were having the same problems with medical-related bankruptcy. What he found was shocking.

Traveling to the United Kingdom, Japan, Germany, Taiwan, and Switzerland, Reid found that health-related bankruptcy is almost unheard of in these countries. Unlike the United States, all five of the visited countries have universal health care and pay a lot less.

Switzerland spends the second-highest amount on health care, but the government still spends 44-percent less per capita than the United States.

The full program, "Sick Around the World," is available online, along with a list of resources and a Q&A with Reid.

All the countries have varying degrees of private, market-based health care, like the United States. They, however, also limit the level of freedom the health care market can have. According to Frontline:

First, insurance companies must accept everyone and can't make a profit on basic care. Second, everybody's mandated to buy insurance, and the government pays the premium for the poor. Third, doctors and hospitals have to accept one standard set of fixed prices.

It's unnecessary for health care costs to send hundreds of thousands of Americans into debt each year. As Reid has learned, it is possible to make health care universal and affordable in a free-market economy.

Children learn based on their teachers-- and often national policy regarding education. This month's issue of Foreign Policy explores how the way Germany and France teach economics may spell a dismal economic future.

Millions of children are being raised on prejudice and disinformation. Educated in schools that teach a skewed ideology, they are exposed to a dogma that runs counter to core beliefs shared by many other Western countries. They study from textbooks filled with a doctrine of dissent, which they learn to recite as they prepare to attend many of the better universities in the world. Extracting these children from the jaws of bias could mean the difference between world prosperity and menacing global rifts. And doing so will not be easy. But not because these children are found in the madrasas of Pakistan or the state-controlled schools of Saudi Arabia. They are not. Rather, they live in two of the world’s great democracies—France and Germany.
