World News Roundup ARAB TIMES, THURSDAY, OCTOBER 15, 2015 18 INTERNATIONAL Palaeontology Discovery Hot or not? Dinos not truly ‘cold-blooded’ PARIS, Oct 14, (AFP): A new method to chemically analyse dinosaur egg shells has allowed sci- entists to gauge the extinct lizards’ body tempera- ture, researchers said on Tuesday. The findings support recent work by other teams that dinosaurs were neither warm- nor cold-blood- ed, but some- where in between, researchers wrote in the journal Nature Communications. But it also indicated that body temperature differed between dinosaur species. “The temperatures we measured suggest that at least some dinosaurs were not fully endotherms (warm-blooded) like modern birds,” said the study’s lead author Robert Eagle of the University of California Los Angeles (UCLA). “They may have been intermedi- ate — somewhere between modern alligators and crocodiles and mod- ern birds.” This meant they could produce heat internally and raise their body temperature, but not maintain it at a consistently high level. Warm-blooded animals, or endotherms, typically maintain a constant body temperature while cold-blooded ones, called ectotherms, rely on external heat sources to warm up — like lizards lazing in the Sun. Scientists have been debating for 150 years whether dinosaurs were warm-blooded hunters, like mam- mals, or cold-blooded and sluggish like many reptiles. Capacity “If dinosaurs were at least endothermic (warm-blooded) to a degree, they had more capacity to run around searching for food than an alligator would,” Eagle said. Warm-blooded animals typically need to eat a great deal to stay warm, forcing them into frequent hunts or to eat large quantities of plants. The team said it used a pioneer- ing procedure to measure the inter- nal temperature of dinosaur moth- ers which lived some 71-80 million years ago. They examined the chemical makeup of the shells of 19 fos- silised eggs from two types of dinosaur, unearthed in Argentina and Mongolia’s Gobi desert. One was a large, long-necked titanosaur sauropod, a member of the largest animal group to ever to walk the Earth, and the other a smaller oviraptorid — closely relat- ed to Tyrannosaurus rex and mod- ern birds. The team analysed the behaviour of two rare isotopes in calcium car- bonate, a key ingredient in egg shells. The isotopes — carbon-13 and oxygen-18 — tend to cluster together more closely at colder temperatures. “This technique tells you about the internal body temperature of the female dinosaur when she was ovu- lating,” said Eagle’s colleague, Aradhna Tripati. The titanosaur mother’s tempera- ture had been about 38 degrees Celsius (100 degrees Fahrenheit), the team found. A healthy human temperature is 37C. The smaller dinosaur was sub- stantially cooler, probably below 32C — but was probably able raise its temperature above that of its environment, said the team. Fossilised soil from around the nest area in Mongolia had been about 26C. “The oviraptorid dinosaur body temperatures were higher than the environmental temperatures — suggesting they were not truly cold- blooded but intermediate,” said Tripati.

The film contends that their demise will sig- nify the crash of the global ecosys- tem along with the disappearance of honey bees and the melting of the glaciers. The film will open in New York at Cinema Village on Dec 4 and in Los Angeles at Laemmle Monica on Dec 11, followed by a release in over 30 markets nationwide and a subsequent DVD and digital release next year. Producers are SongbirdSOS Productions Inc. and Films a Cinq/ARTE. “The Messenger” won the prize for Best Conservation Program at the Jackson Hole Wildlife Film Festival. In this ESA/Hubble & NASA handout released Oct 12, 2015 NGC 4639 is shown, a beautiful exam- ple of a type of galaxy known as a barred spiral. It lies over 70 million light-years away in the con- stellation of Virgo and is one of about 1,500 galaxies that make up the Virgo Cluster. In this image, taken by the NASA/ESA Hubble Space Telescope, one can clearly see the bar running through the bright, round core of the galaxy. Bars are found in around two thirds of spiral galaxies, and are thought to be a natural phase in their evolution. The galaxy’s spiral arms are sprinkled with bright regions of active star formation. Each of these tiny jewels is actually several hundred light-years across and contains hundreds or thousands of newly formed stars. But NGC 4639 also conceals a dark secret in its core - a massive black hole that is consuming the surrounding gas. This is known as an active galactic nucleus (AGN), and is revealed by characteristic features in the spec- trum of light from the galaxy and by X-rays produced close to the black hole as the hot gas plunges towards it. Most galaxies are thought to contain a black hole at the centre.

(AFP) Jewell Heck Research urged on: A coalition of scholars across the West is urging the fed- eral government to partner with the National Academy of Sciences to study the future of the Colorado River, includ- ing if climate change is leading to reduced stream flow. Twenty-three scholars from Western uni- versities sent a letter Tuesday to Interior Secretary Sally Jewell detailing their request for more scientific research on a host of issues related to the Colorado River. Chief among the concerns is if there will be enough water in the river to sup- port 36 million users in seven US states and parts of Mexico over the next 50 years. The scholars argue the federal govern- ment is relying on a projection of a 9-per- cent stream flow decline by 2060, while skimming over other estimates that sug- gest it could fall by as much as 45 percent by 2050 due to climate change. Secretary Jewell was expected to receive the letter early Wednesday. The Bureau of Reclamation this summer issued the results of a nearly three-year study that concluded that there will be sig- nificant shortfalls between water supply and demand on the Colorado River over the next 50 years.

The 208-foot-tall (63-meter) rocket carrying a load of cargo for the International Space Station exploded less than three minutes after liftoff from Florida on June 28. The cause of the accident was traced to faulty bracket inside the rocket’s upper-stage engine.

(AFP) ❑ ❑ ❑ Heck is buried in Manila: American Nobel laureate for chemistry Richard Heck, who designed a method of building complex molecules that has helped fight cancer, protect crops and make electronic devices, was buried Tuesday in a metro- politan Manila cemetery beside the tomb of his Filipino wife. He was 84. The professor emeritus at the University of Delaware died Saturday due to multiple organ failure after bouts with pneumonia, diabetes and liver cirrhosis, said Michael Nardo, his nephew-in-law who had taken care of Heck and his wife over the last decade. Heck, whose interest in plants as a child led him to a career in chemistry, shared the Nobel prize for chemistry in 2010 with two Japanese scientists. He retired to the Philippines with his wife Socorro Nardo-Heck, who died in 2012. The couple had no children. Family members and fellow scientists paid tribute to Heck’s humility and sim- plicity despite his achievements. Wreaths and prayer cards from various scientific groups adorned a chapel where he was interred. (AP) Spring to come to US 3 weeks early Emissions cuts not enough: Canete RABAT, Morocco, Oct 14, (Agencies): Europe’s climate chief has acknowl- edged for the first time that climate pledges made by national governments ahead of a major UN conference fall short of meeting the international goal of keeping global warming below 2 degrees Celsius (3.6 degrees Fahrenheit). In an interview Monday with The Associated Press, Climate Commissioner Miguel Arias Canete said the EU’s pro- jections show the current pledges to curb greenhouse gas emissions would put world on a path toward 3 degrees Celsius (5.4 degrees Fahrenheit) of warming. That’s a level that scientists say could result in dangerous changes in the Earth’s climate system, such as rising seas flood- ing coastal areas and small island nations. Canete said the fact that almost 150 countries have made pledges ahead of a December climate conference in Paris is “an extraordinary result” — but not enough. “In some G20 countries, there is margin of maneuver to increase the level of ambition,” he said, referring to the Group of 20 major economies. Canete didn’t rule out improving the European Union’s own target of reducing emissions by at least 40 percent by 2030 compared to 1990 levels, even though he called it the “most ambitious” of all. Target “At the moment, we come along with this target to the talks,” he said, speaking on the sidelines of a climate conference in Rabat. “Let’s see what is in the final version.” Canete noted the target of the EU — the world’s third biggest greenhouse gas polluter — didn’t include interna- tional credits for funding to reduce emissions in developing countries “which opens the possibility of raising the level of ambition.” The deal envisioned in Paris would be the first where all countries, both rich and poor, commit to take action to fight global warming, which scientists say is chiefly caused by burning fossil fuels. To make sure that temperatures don’t rise more than 2 degrees Celsius compared to pre-industrial times — they are already almost halfway there — the Paris deal should include a mechanism to review emissions tar- gets every five years, Canete said. The EU position wants the first review in 2025 but Canete indicated an earlier date was not out of the ques- tion. “The date is not so important,” he added. “The important thing is to have a permanent mechanism of raising ambition periodically.” Climate policy expert Jennifer Morgan of the World Resources Institute, a Washington-based environmental think tank, said the date of the first review after Paris is quite significant. “Science tells us we cannot wait 10 years, especially noting how much more there is to be done,” Morgan said. Battering Marshall Islands Foreign Minister Tony de Brum, who was unable to travel to Rabat because of a storm bat- tering the Pacific nation, said locking in the current emissions targets would spell disaster. “Without much more urgent and ambitious action, my country simply won’t survive,” he said in a statement. All major economies have present- ed emissions pledges for after 2020 as part of negotiations for the Paris deal but they all look different. Developed countries including the US and the EU have pledged absolute reductions in emissions, while China has vowed to peak its emissions by 2030 and India has pledged to reduce its emissions per unit of gross domestic product. Saudi Arabia and other oil and gas- producing countries in the Middle East are among those that haven’t proposed any targets yet. “I had talks with Saudi Arabia last week in Istanbul and they told me they will be coming along with their (tar- get) in due course,” Canete said. “I’m confident that (it) will arrive before Paris.” Meanwhile, French owned energy firm EDF on Tuesday urged the adop- tion of a carbon price floor in the run- up to a climate warming conference in Paris, backing a government proposal to that effect for the sector in France. “Most firms today have carbon price scenarios for their investments, and so have we,” said Claude Nahon, EDF’s director of sustainable development. “But we must go further,” Nahon told a news conference. “Of course we support a proposal by (Energy Minister Segolene) Royal to create a carbon floor in France, or even Europe.” France is out to reduce its depend- ability on nuclear power in favour of renewables and last week Royal floated the idea, as part of an upcoming parlia- mentary bill, of a carbon floor price to offset imperfections in a European mar- ket vying to slash carbon emissions and push firms to adopt cleaner technology. In July, legislators passed a bill to increase the target price of carbon to 56 euros ($63.7) a ton from 2020, then 100 euros a ton in 2030. The current 14.50 euros is due to rise next year to 22 euros. Also: MIAMI: Rising global temperatures due to climate change will bring spring to the United States about three weeks earlier than usual in the decades to come, scientists said Wednesday. While those who are weary of win- ter may welcome such news, scientists say the shift will also have long-reach- ing impacts on the growing season of plants and the animals that depend upon them. “Our projections show that winter will be shorter — which sound greats great for those of us in Wisconsin,” said Andrew Allstadt of the University of Wisconsin, Madison, a co-author of the study in the Oct 14 edition of the journal Environmental Research Letters.
