Global warming is likely to disrupt a natural cycle of ice ages and contribute to delaying the onset of the next big freeze until about 100,000 years from now, scientists said on Wednesday. In the past million years, the world has had about 10 ice ages before swinging back to warmer conditions like the present. In the last ice age that ended 12,000 years ago, ice sheets blanketed what is now Canada, northern Europe and Siberia. In a new explanation for the long-lasting plunges in global temperatures that cause ice ages, scientists pointed to a combination of long-term shifts in the Earth's orbit around the sun, together with levels of carbon dioxide in the atmosphere. They said the planet seemed naturally on track to escape an ice age for the next 50,000 years, an unusually long period of warmth, according to the study led by the Potsdam Institute for Climate Impact Research. But rising man-made greenhouse gas emissions since the Industrial Revolution began in the 18th century … [Read more...] about Global warming could stave off next ice age for 100,000 years
Earth 100 million years from now
One minute brightly lit, the next plunged into darkness — iconic landmarks around the world will cut their lights Saturday for the “Earth Hour” campaign against climate change. Organisers expect hundreds of millions of people across the globe to turn off their lights for 60 minutes on Saturday night — at 8:30pm local time — in a symbolic show of support for the planet. Many of the world’s most iconic attractions, including Sydney Opera House, the Empire State Building and the Eiffel Tower will take part. “What started as an event in Sydney in 2007 with two million people has now become a tradition across the country and across the world,” Dermot O’Gorman, head of WWF-Australia, said. “It’s now an organic, people-powered movement… which is fantastic.” Last year more than 150 countries participated in the event which saw some of the world’s most iconic landmarks dim, and this year the movement has … [Read more...] about Millions to switch off for ‘Earth Hour’
Contestant withdraws from Miss Vietnam under suspicion of cosmetic surgery Pham My Linh has withdrawn from Miss Vietnam 2014 after she was accused of having had a nose job. Linh said in the letter sent to the organising board that she wanted to withdraw from the contest because she could not bear the pressure of public opinion and because her family was opposed to her participation. Before a press conference to announce the final round, the organisers received an anonymous letter denouncing Linh for violating the contest regulations by having comestic surgery. Upon entering the contest, Linh affirmed that she had not had such procedures done. The orgnising board asked that she be examined by a doctor, who found no suspicious signs. Nonetheless, they set up an investigative panel to look into the case further. Linh agreed to cooperate, so her withdrawal letter came as a surprise to many. Another candidate, Huynh Thi Thuy Van, also withdrew from the contest for health-related reasons. … [Read more...] about Contestant withdraws from Miss Vietnam under suspicion of cosmetic surgery
Mass extinctions have served as huge reset buttons that dramatically changed the diversity of species found in oceans all over the world, according to a comprehensive study of fossil records. The findings suggest humans will live in a very different future if they drive animals to extinction, because the loss of each species can alter entire ecosystems. Some scientists have speculated that effects of humans - from hunting to climate change - are fueling another great mass extinction. A few go so far as to say we are entering a new geologic epoch, leaving the 10,000-year-old Holocene Epoch behind and entering the Anthropocene Epoch, marked by major changes to global temperatures and ocean chemistry, increased sediment erosion, and changes in biology that range from altered flowering times to shifts in migration patterns of birds and mammals and potential die-offs of tiny organisms that support the entire marine food chain. Scientists had once thought species diversity could help buffer … [Read more...] about Earth on verge of huge reset button?
VietNamNet Bridge – Sandals in my hands, I wade in the waters of Sam Son Beach, under the sparkling stars. Thousands of waves crash on my legs as I walk through the shallow water. It's so nice to feel the sand under my feet while listening to the waves hum soft melodies. The wind caresses my hair, making me forget the day's burning heat. Go fly a kite: Colourful kites are sold on Sam Son Beach. At 9pm, the beach becomes even more immense with the rising tide. I meet other tourists who, like me, love strolling along the seaside, alone or in groups. Some stand quietly to admire the beach at night, while others shout joyfully, trying to jump over the waves. Another group spends their time taking photos of each other. I am at Sam Son Beach, 180km south of Ha Noi and 16km from central Thanh Hoa City. After travelling four hours by bus from the Giap Bat station in Southern Ha Noi, I finally found myself surrounded by the fresh air of the beach, known as one of the most crowded … [Read more...] about Sam Son offers relaxing break from city grind
