This week, the Public Broadcasting Service aired a NOVA program titled “Dimming the Earth”, which presented research by leading scientists on the complex systems of our global climate and human activity’s effect on it. One of the largest interactions (or “inputs”) humans have with the atmosphere is the ever-increasing use of fossil fuels. Consumption has risen 2% per year for this decade.

Fossil fuels burnt in factories and automobiles send their waste into our atmosphere in two forms. The first is CO₂ and other greenhouse gases, which have received substantial attention in the last few years because of the way they trap heat in the atmosphere. The second is the tiny particles of sulfur dioxide, soot and ash, which scientists call aerosols (basically smog). Research into understanding the negative health effects of air pollution has resulted in the development of catalytic converters for cars as well as devices to remove particulate solids from industrial waste before it reaches the air.

More recently, atmospheric scientists have come upon the phenomenon of the reduction of direct sunlight reaching Earth’s surface— observing a nearly a 5% decline between 1960 and 1990, with evidence of a recovery since then. This has been dubbed the “global dimming” effect, and is probably due to the way these aerosols act upon clouds. It is important to realise that this does not represent a net loss of this much sunshine to the climate system – if so, large temperature declines would have been observed. Instead, the sunshine is absorbed elsewhere in the system, with a much smaller net loss.

Clouds form when moisture gathers around airborne particles, such as pollen or dust. Clouds formed by the aerosol particles emitted by fossil fuel consumption are made of many more tiny droplets than “natural” clouds. These smog-created clouds have two notable effects: they shield sunlight from reaching Earth’s surface and, due to water’s reflective nature, the millions of tiny droplets suspended in them reflect light back into space, allowing even less light to reach Earth.

Many scientists now believe that global dimming caused by these pollutants has mitigated the temperature rises brought about by global warming. Over the last thirty years, Earth’s temperature has increased by about 0.5 oC.

In the absence of global dimming, however, the Earth might be 0.3 oC warmer than it currently is, suggesting that a “tug-of-war” exists between greenhouse gases and particulates released by burning fossil fuels. Efforts to mitigate the human health dangers of smog have allowed more heat into our atmosphere and brought about a sharper increase in global warming.

Dr. James E. Hansen, professor at Columbia University and the head of the Goddard Institute for Space Studies [1], believes that if we continue on our current pattern, this warming could be as much as five degrees in the next thirty years and ten to fourteen degrees over the course of the century. Such a temperature rise would devastate life on Earth, likely bringing on a cascade of self-reinforcing warming effects. Earth’s forests drying and burning, a steady thawing of the Greenland and arctic ice sheets, and, most dangerous of all, a release of the methane hydrates that are now frozen at the bottom of the oceans, could remake the planet into something inhospitable to human life. Dr. Hansen warns that, according to his research, man has just 10 years to reduce greenhouse gases before global warming and other responses to human activity by Earth’s climate reach a “tipping point”, becoming unstoppable.

U.S. Democratic Party presidential candidate John Wolfe, Jr. of Tennessee took some time to answer a few questions from Wikinews reporter William S. Saturn.

Wolfe, an attorney based out of Chattanooga, announced his intentions last year to challenge President Barack Obama in the Democratic Party presidential primaries. So far, he has appeared on the primary ballots in New Hampshire, Missouri, and Louisiana. In Louisiana, he had his strongest showing, winning 12 percent overall with over 15 percent in some congressional districts, qualifying him for Democratic National Convention delegates. However, because certain paperwork had not been filed, the party stripped Wolfe of the delegates. Wolfe says he will sue the party to receive them.

Wolfe will compete for additional delegates at the May 22 Arkansas primary and the May 29 Texas primary. He is the only challenger to Obama in Arkansas, where a May 10 Hendrix College poll of Democrats shows him with 38 percent support, just short of the 45 percent for Obama. Such an outing would top the margin of Texas prison inmate Keith Russell Judd, who finished 18 percent behind Obama with 41 percent in the West Virginia Democratic primary; the strongest showing yet against the incumbent president. Despite these prospects, the Democratic Party of Arkansas has already announced that if Wolfe wins any delegates in their primary, again, due to paperwork, the delegates will not be awarded. Wolfe will appear on the Texas ballot alongside Obama, activist Bob Ely, and historian Darcy Richardson, who ended his campaign last month.

Wolfe has previously run for U.S. Congress as the Democratic Party’s nominee. On his campaign website, he cites the influence “of the Pentagon, Wall Street, and corporations” on the Obama administration as a reason for his challenge, believing these negatively affect “loyal Americans, taxpayers and small businesses.” Wolfe calls for the usage of anti-trust laws to break up large banks, higher taxes on Wall Street, the creation of an “alternative federal reserve” to assist community banks, and the implementation of a single-payer health care system.

With Wikinews, Wolfe discusses his campaign, the presidency of Barack Obama, corporations, energy, the federal budget, immigration, and the nuclear situation in Iran among other issues.

A United States District federal judge ruled Thursday that the Bush administration’s wiretapping program is “unconstitutional” and that it “must be halted immediately.” The ruling came in a lawsuit filed by the American Civil Liberties Union(ACLU) challenging federal intelligence agencies’ eavesdropping of international phone calls without obtaining court warrants.

The defendants, the National Security Agency (NSA), the Central Security Service and NSA Director and Chief of the Central Security Service, Lieutenant General Keith B. Alexander asserted that they cannot defend their case without exposing state secrets.

Judge Anna Diggs Taylor, US District Judge for the Eastern District of Michigan, wrote in an opinion that the defense argument was “without merit”.

“Defendants have supported these arguments without revealing or relying on any classified information,” Taylor wrote in an opinion accompanying the ruling.

Judge Taylor also ruled that the tapping violates “the separation of powers enshrined in the Constitution, privacy and free speech.”

The Bush Administration has been firmly committed to the wiretapping, known as the Terrorist Surveillance Program (TSP), and said the practice has a valid basis in law, despite public criticism. Defenders of the program contended that the President has the authority under the AUMF and the Constitution to authorize the continued use of the TSP.

Judge Taylor wrote in her 43-page opinion that, “We must first note that the Office of the Chief Executive has itself been created, with its powers, by the Constitution. There are no hereditary Kings in America and no powers not created by the Constitution. So all ‘inherent powers’ must derive from that Constitution.”

The ACLU filed the lawsuit to protect the privacy and unreasonable search of lawful verbal exchanges by journalists, lawyers and scholars among others. The court order ruled that powers granted by TSP violated the U.S. Separation of Powers doctrine, the Administrative Procedure Act, and the First and Fourth Amendments.

An appeal over the court decision is expected.

In 2001, President George W. Bush approved a program that allowed the NSA to monitor international calls for possible terrorist activity when one party to the call was outside U.S. territory. The government argued that the program is well within the president’s authority. The Justice Department wrote, “In the ongoing conflict with al Qaeda and its allies, the president has the primary duty under the Constitution to protect the American people”.

ENGLAND – UK Health Secretary John Reid has proposed widespread legislative and health care changes in a new white paper on public health released Tuesday. Titled “Choosing Health”, the paper details government plans to restrict smoking in public places, limit ‘junk food‘ advertisements to children, make available “lifestyle trainers”, campaign against sexually transmitted diseases and tobacco, and improve food labelling.

The white paper comes after extensive public comment that involved 150,000 people.

Smoking would be restricted in enclosed public spaces, restaurants, workplaces, and some pubs. The ban would be enacted gradually, affecting government and NHS buildings in 2006, enclosed public places in 2007, and private property in 2008. Permanent exemption would be granted to pubs that do not serve prepared food — though not at the bar — as well as private clubs, a decision that has provoked some to call the measure incomplete. Up to 90% of pubs are expected to be affected. The Scottish executive proposed a complete ban on smoking in enclosed public places last week, and Ireland has already banned smoking in pubs and restaurants.

Food advertisements targeted to children would be banned until 9pm, under the White Paper’s proposals. The restriction is a measure to tackle rising rates of childhood obesity. The government also intends to develop voluntary standards on food and drink advertisements to children with industry, only threatening legislation if an acceptable standard is not reached by 2007. Additionally, low income families would receive vouchers for fresh fruit, vegetables, milk, and infant formula. School lunches would also be held to stricter nutritional standards. Reid has warned that unless childhood obesity is tackled, “we face the prospect of children having shorter life expectancy than their parents”.

Food labelling would also be improved, with a “traffic light” system implemented. Packaged food would be evaluated based on its fat, sugar, and salt content.

The paper is unusual for suggesting a more holistic approach to health care, offering for the first time “lifestyle trainers.” The National Health Service would be funding with an additional £1bn to make people’s overall lives healthier, which is expected to save £30bn in preventable illness.

The paper additionally makes mention of reducing accidents, which affected 2.7m people last year and is a leading cause of child death, curb binge drinking, and reduce substance abuse among youths.

The paper has been criticized by many parties. The Tory Shadow Health Secretary has criticized the Labour government’s comprehensiveness and creation of a “new nanny state approach”. He has additionally described it as “gimmicks”. The Liberal Democrats have accused the government of not being comprehensive enough. It has also been criticized by the British Medical Association as being implemented too slowly, saying “When lives need saving, doctors act immediately”.

Mr. Reid has argued against the nanny state label, saying “In a free society, men and women ultimately have the right within the law to choose their own lifestyle, even when it may damage their own health. But people do not have the right to damage the health of others, or to impose an intolerable degree of inconvenience or nuisance on others … This is a sensible solution which balances the protection of the majority with the personal freedom of the minority in England”.

London, UK — The Vodafone GPRS (General Packet Radio Service) Mobile Data Network within the UK was off the air for several hours, but Vodafone staff were unable to supply any details as to how or why this had happened. The incident seems to have originated within Southern England, but spread “nationwide” within a short period.

Customers were therefore unable to access data services for a protracted period, including WAP browsing from mobile phones, email from personal devices like Blackberries and Windows Mobile Messengers, and full access over data cards from laptops.

Some criticism has been levelled at the company for failing to provide an easy source of information on the problem, with the only realistic option being to queue for a response from a call centre, as no information could be found on their public-facing website. This practice, whilst far from unique to Vodafone within the telecommunications industry, contrasts poorly with the common practice for most ISPs (Internet Service Providers), who conventionally provide a “system status” page on their website.

Pressure is building on Myanmar to decline next years revolving ASEAN chair due to its human rights record. The US Senate Majority Whip Mitch McConnell, has said that the USA should boycott ASEAN meetings next year if Myanmar takes the chair.

The UN special envoy to Myanmar, Tan Sri Razali Ismail, has backed moves by Malaysian lawmakers earlier this week against Myanmar’s chairing, saying “The UN is always on the side of democracy. It supports the principles these people are pushing and these principles are very important for all governments to adhere to,”

“I don’t think there’s any attempt to punish Myanmar but to make them understand ASEAN is guided by certain principles in order to be a member or in order to be leading ASEAN for a certain period,”

Filipino legislators are also following Malaysian lawmakers, and are expected to propose that all member countries adopt a stand on Myanmar when ASEAN legislators meet in an Inter-Parliamentary Union conference in Manila on April 3.

A robotic system at Stanford Medical Center was used to perform a laparoscopic gastric bypass surgery successfully with a theoretically similar rate of complications to that seen in standard operations. However, as there were only 10 people in the experimental group (and another 10 in the control group), this is not a statistically significant sample.

If this surgical procedure is as successful in large-scale studies, it may lead the way for the use of robotic surgery in even more delicate procedures, such as heart surgery. Note that this is not a fully automated system, as a human doctor controls the operation via remote control. Laparoscopic gastric bypass surgery is a treatment for obesity.

There were concerns that doctors, in the future, might only be trained in the remote control procedure. Ronald G. Latimer, M.D., of Santa Barbara, CA, warned “The fact that surgeons may have to open the patient or might actually need to revert to standard laparoscopic techniques demands that this basic training be a requirement before a robot is purchased. Robots do malfunction, so a backup system is imperative. We should not be seduced to buy this instrument to train surgeons if they are not able to do the primary operations themselves.”

There are precedents for just such a problem occurring. A previous “new technology”, the electrocardiogram (ECG), has lead to a lack of basic education on the older technology, the stethoscope. As a result, many heart conditions now go undiagnosed, especially in children and others who rarely undergo an ECG procedure.
