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.

Evansville, Indiana, United States — This past week marked the opening night of an Andy Warhol exhibit at the University of Southern Indiana. USI’s art gallery, like 189 other educational galleries and museums around the country, is a recipient of a major Warhol donor program, and this program is cultivating new interest in Warhol’s photographic legacy. Wikinews reporters attended the opening and spoke to donors, exhibit organizers and patrons.

The USI art gallery celebrated the Thursday opening with its display of Warhol’s Polaroids, gelatin silver prints and several colored screen prints. USI’s exhibit, which is located in Evansville, Indiana, is to run from January 23 through March 9.

The McCutchan Art Center/Pace Galleries at USI bases its exhibit around roughly 100 Polaroids selected from its collection. The Polaroids were all donated by the Andy Warhol Photographic Legacy Program, according to Kristen Wilkins, assistant professor of photography and curator of the exhibit. The Andy Warhol Foundation for the Visual Arts made two donations to USI Art Collections, in 2007 and a second recently.

Kathryn Waters, director of the gallery, expressed interest in further donations from the foundation in the future.

Since 2007 the Andy Warhol Photographic Legacy Program has seeded university art galleries throughout the United States with over 28,000 Andy Warhol photographs and other artifacts. The program takes a decentralized approach to Warhol’s photography collection and encourages university art galleries to regularly disseminate and educate audiences about Warhol’s artistic vision, especially in the area of photography.

Wikinews provides additional video, audio and photographs so our readers may learn more.

Wilkins observed that the 2007 starting date of the donation program, which is part of the Andy Warhol Foundation for the Visual Arts, coincided with the 20th anniversary of Andy Warhol’s death in 1987. USI was not alone in receiving a donation.

K.C. Maurer, chief financial officer and treasurer at the Andy Warhol Foundation, said 500 institutions received the initial invitation and currently 190 universities have accepted one or more donations. Institutional recipients, said Mauer, are required to exhibit their donated Warhol photographs every ten years as one stipulation.

While USI is holding its exhibit, there are also Warhol Polaroid exhibits at the Tang Teaching Museum and Art Gallery at Skidmore College in Saratoga Springs, New York and an Edward Steichen and Andy Warhol exhibit at the Mary & Leigh Block Museum of Art at Northwestern University in Evanston, Illinois. All have received Polaroids from the foundation.

University exhibits can reach out and attract large audiences. For example, the Weatherspoon Art Museum at the University of North Carolina at Greensboro saw attendance levels reach 11,000 visitors when it exhibited its Warhol collection in 2010, according to curator Elaine Gustafon. That exhibit was part of a collaboration combining the collections from Duke University, located in Durham, North Carolina, and University of North Carolina at Chapel Hill, which also were recipients of donated items from the Andy Warhol Photographic Legacy Program.

Each collection donated by the Andy Warhol Photographic Legacy Program holds Polaroids of well-known celebrities. The successful UNC Greensboro exhibit included Polaroids of author Truman Capote and singer-songwriter Carly Simon.

“I think America’s obsession with celebrity culture is as strong today as it was when Warhol was living”, said Gustafon. “People are still intrigued by how stars live, dress and socialize, since it is so different from most people’s every day lives.”

Wilkins explained Warhol’s obsession with celebrities began when he first collected head shots as a kid and continued as a passion throughout his life. “He’s hanging out with the celebrities, and has kind of become the same sort of celebrity he was interested in documenting earlier in his career”, Wilkins said.

The exhibit at USI includes Polaroids of actor Dennis Hopper; musician Nick Rhodes of Duran Duran; publishers Jann Wenner of Rolling Stone Magazine and Carlo De Benedetti of Italy’s la Repubblica; disco club owner Steve Rubell of Studio 54; photographers Nat Finkelstein, Christopher Makos and Felice Quinto; and athletes Vitas Gerulaitis (tennis) and Jack Nicklaus (golf).

Wikinews observed the USI exhibit identifies and features Polaroids of fashion designer Halston, a former resident of Evansville.

University collections across the United States also include Polaroids of “unknowns” who have not yet had their fifteen minutes of fame. Cynthia Thompson, curator and director of exhibits at the University of Arkansas, Fayetteville, said, “These images serve as documentation of people in his every day life and art — one which many of us enjoy a glimpse into.”

Warhol was close to important touchstones of the 1960s, including art, music, consumer culture, fashion, and celebrity worship, which were all buzzwords and images Wikinews observed at USI’s opening exhibit.

He was also an influential figure in the pop art movement. “Pop art was about what popular American culture really thought was important”, Kathryn Waters said. “That’s why he did the Campbell Soup cans or the Marilyn pictures, these iconic products of American culture whether they be in film, video or actually products we consumed. So even back in the sixties, he was very aware of this part of our culture. Which as we all know in 2014, has only increased probably a thousand fold.”

“I think everybody knows Andy Warhol’s name, even non-art people, that’s a name they might know because he was such a personality”, Water said.

Hilary Braysmith, USI associate professor of art history, said, “I think his photography is equally influential as his graphic works, his more famous pictures of Marilyn. In terms of the evolution of photography and experimentation, like painting on them or the celebrity fascination, I think he was really ground-breaking in that regard.”

The Polaroid format is not what made Warhol famous, however, he is in the company of other well-known photographers who used the camera, such as Ansel Adams, Chuck Close, Walker Evans, Robert Mapplethorpe, and Helmut Newton.

Wilkins said, “[Warhol] liked the way photo booths and the Polaroid’s front flash looked”. She explained how Warhol’s adoption of the Polaroid camera revealed his process. According to Wilkins, Warhol was able to reproduce the Polaroid photograph and create an enlargement of it, which he then could use to commit the image to the silk screen medium by applying paint or manipulating them further. One of the silk screens exhibited at USI this time was the Annie Oakley screen print called “Cowboys and Indians” from 1987.

Wilkins also said Warhol was both an artist and a businessperson. “As a way to commercialize his work, he would make a blue Marilyn and a pink Marilyn and a yellow Marilyn, and then you could pick your favorite color and buy that. It was a very practical salesman approach to his work. He was very prolific but very business minded about that.”

“He wanted to be rich and famous and he made lots of choices to go that way”, Wilkins said.

Kiara Perkins, a second year USI art major, admitted she was willing to skip class Thursday night to attend the opening exhibit but then circumstances allowed for her to attend the exhibit. Why did she so badly want to attend? “It’s Warhol. He is a legend.”

For Kevin Allton, a USI instructor in English, Warhol was also a legend. He said, “Andy Warhol was the center of the Zeitgeist for the 20th century and everything since. He is a post-modern diety.”

Allton said he had only seen the Silver Clouds installation before in film. The Silver Clouds installation were silver balloons blown up with helium, and those balloons filled one of the smaller rooms in the gallery. “I thought that in real life it was really kind of magical,” Allton said. “I smacked them around.”

Elements of the Zeitgeist were also playfully recreated on USI’s opening night. In her opening remarks for attendees, Waters pointed out those features to attendees, noting the touches of the Warhol Factory, or the studio where he worked, that were present around them. She pointed to the refreshment table with Campbell’s Soup served with “electric” Kool Aid and tables adorned with colorful gumball “pills”. The music in the background was from such bands as The Velvet Underground.

The big hit of the evening, Wikinews observed from the long line, was the Polaroid-room where attendees could wear a Warhol-like wig or don crazy glasses and have their own Polaroid taken. The Polaroids were ready in an instant and immediately displayed at the entry of the exhibit. Exhibit goers then became part of the very exhibit they had wanted to attend. In fact, many people Wikinews observed took out their mobiles as they left for the evening and used their own phone cameras to make one further record of the moment — a photo of a photo. Perhaps they had learned an important lesson from the Warhol exhibit that cultural events like these were ripe for use and reuse. We might even call these exit instant snap shots, the self selfie.

Researchers say that new, ten million-year-old fossils found in Ethiopia, prove that the theory that humans may have evolved from a species of great apes eight million years ago, may not be true, but that humans may have split from apes as long as 10.5 million years ago.

At least nine fossilized teeth, one canine tooth and eight molars, of a previously unknown species of apes found in Africa were discovered by a team of researchers from Ethiopia and Japan who then compared the 3-D make up of the teeth to other fossils that date back as far as 8 million years and found that the fossils are likely a “direct ancestor” of apes currently living in Africa and that the new ape fossils were that of a species of gorilla who ate mostly plants high in fiber.

Current fossils and research say that the evolutionary split from apes to humans occurred at least eight million years ago. The new fossils say that the split may have happened as long as 10.5 million years ago.

“Based on this fossil, that means the split is much earlier than has been anticipated by the molecular evidence. That means everything has to be put back,” said researcher at the Rift Valley Research Service in Ethiopia and a co-author of the study, Berhane Asfaw.

Despite the finds, other researchers are not convinced that the findings are correct.

“It is stretching the evidence to base a time scale for the evolution of the great apes on this new fossil. These structures appear on at least three independent lineages of apes, including gorillas, and they could relate to a dietary shift rather than indicating a new genetic trait,” said a Professor at the London Natural History Museum in the United Kingdom, Peter Andrews who also added, “but the fossil evidence for the evolution of our closest living relatives, the great apes, is almost non-existent.

Researchers have named the newly discovered species Cororapithecus abyssinicus whose remains were found in the Afar Region of Ethiopia, the same place where the remains of Lucy were discovered in 1974.

Philippines Foreign Secretary Albert del Rosario is scheduled to visit China from July 7 to 9, raising hopes that a territorial dispute between the two countries may be resolved.

A six-nation dispute has escalated in the sea concerning territorial claims to several islands including the Spratly Islands. The area is thought to be rich in natural gas and oil. Both the Philippines and China wish to have a peaceful resolution to this conflict. “I’ve been invited to Beijing and we’re looking for peaceful means to settle the challenges facing us,” said Del Rosario.

The news comes after the United States and the Philippines began a series of naval exercises last week in the South China Sea, scheduled to last for 11 days. A Philippine military commander stated that the drills are part of an annual series of activities taking place under a defense agreement between the two countries and have nothing to do with the territorial dispute.

The Philippines maintains a close relation with the U.S. as a former territory of the nation.

The drills come at a time when several competing disputes in the South China Sea have begun to intensify. “Since February 25th, we actually have noted as many as nine intrusions of different varieties, but clearly becoming more aggressive and more frequent,” said Del Rosario. Several countries in Asia, including China, the Philippines, Vietnam, Brunei, Malaysia, and Taiwan, have territorial claims in the area spanning the Spratly and Paracel Islands. The region may be rich in oil and gas reserves. The US and Philippines have urged the Association of Southeast Asian Nations (ASEAN) to address the conflict.

Secretary of State Hillary Clinton has argued that the United States would remain neutral regarding the disputes. She has also said that the United States has a “national interest” in freedom of navigation, respect for international law, and unimpeded, lawful commerce in the South China Sea.” Both countries are bound by a 1951 Mutual Defense Treaty.

On June 27, the US Senate unanimously passed a motion condemning “the use of force by naval and maritime security vessels from China in the South China Sea.” China, on the other hand, has stated that it will not use force to resolve disputes in the South China Sea.

Fears of contaminated bone and skin grafts are being felt by unsuspecting patients following the revelation that funeral homes may have been looting corpses.

Janet Evans of Marion Ohio was told by her surgeon, “The bone grafts you got might have been contaminated”. She reacted with shock, “I was flabbergasted because I didn’t even know what he was talking about. I didn’t know I got a bone graft until I got this call. I just thought they put in screws and rods.”

The body of Alistair Cooke, the former host of “Masterpiece Theatre,” was supposedly looted along with more than 1,000 others, according to two law enforcement officials close to the case. The tissue taken was typically skin, bone and tendon, which was then sold for use in procedures such as dental implants and hip replacements. According to authorities, millions of dollars were made by selling the body parts to companies for use in operations done at hospitals and clinics in the United States and Canada.

A New Jersey company, Biomedical Tissue Services, has reportedly been taking body parts from funeral homes across Brooklyn, New York. According to ABC News, they set up rooms like a “surgical suite.” After they took the bones, they replaced them with PVC pipe. This was purportedly done by stealth, without approval of the deceased person or the next of kin. 1,077 bodies were involved, say prosecuters.

Investagators say a former dentist, Michael Mastromarino, is behind the operation. Biomedical was considered one of the “hottest procurement companies in the country,” raking in close to $5 million. Eventually, people became worried: “Can the donors be trusted?” A tissue processing company called LifeCell answered no, and issued a recall on all their tissue.

Cooke’s daughter, Susan Cooke Kittredge, said, “To know his bones were sold was one thing, but to see him standing truncated before me is another entirely.” Now thousands of people around the country are receiving letters warning that they should be tested for infectious diseases like HIV or hepatitis. On February 23, the Brooklyn District Attorney indicted Mastromarino and three others. They are charged with 122 felony counts, including forgery and bodysnatching.
