    A NASA satellite designed to precisely measure changes in Earth’s ice sheets, glaciers, sea ice and vegetation was launched into polar orbit from California early Saturday. A Delta 2 rocket carrying ICESat-2 lifted off from Vandenberg Air Force Base at 6:02 a.m. and headed over the Pacific Ocean. NASA Earth Science Division director Michael Freilich says that the mission in particular will advance knowledge of how the ice sheets of Greenland and Antarctica contribute to sea level rise. The melt from those ice sheets alone has raised global sea level by more than 1 millimeter (0.04 inch) a year recently,...

    A Dubai-based engineering firm wants to tow icebergs from Antarctica to Dubai in order to provide the city with a reserve of fresh drinking water. The firm will use satellite imagery to select candidate icebergs. It's eyeing icebergs that are between 2,000 and 7,000 feet long, and weigh around 100 million tons. But the plan is short on details: the firm doesn't know exactly how it will get the icebergs to Dubai, or how the icebergs will be stored. What do you do if you're a fast-growing city in the desert with lots of thirsty people and little freshwater reserves?...
  • Carbon Dioxide ‘Leak’ in Southern Ocean May Have Warmed Earth for 11,000 Years

    “We think we may have found the answer. Increased circulation in the Southern Ocean allowed carbon dioxide to leak into the atmosphere, working to warm the planet,” said Princeton University’s Professor Daniel Sigman, co-author of the study. For years, researchers have known that growth and sinking of phytoplankton pumps carbon dioxide deep into the ocean, a process often referred to as the ‘biological pump.’ “The biological pump is driven mostly by the low latitude ocean but is undone closer to the poles, where carbon dioxide is vented back to the atmosphere by the rapid exposure of deep waters to the...

    The newly-reported specimen was obtained from an amber deposit in the Angbamo area in Myanmar’s Kachin province.The fossil is a 1.6-inch (4.75 cm) long postcranial skeleton made up of 97 vertebrae; the snake’s head is missing. It dates from the Late Cretaceous epoch, approximately 99 million years ago.“This snake, named Xiaophis myanmarensis, is linked to ancient snakes from Argentina, Africa, India and Australia,” said University of Alberta’s Professor Michael Caldwell.“It is an important — and until now, missing — component of understanding snake evolution from southern continents, that is Gondwana, in the mid-Mesozoic.” “At 99 million years old, it dates...

    Researchers released a report this week revealing “ultralow surface temperatures” in East Antarctica that surpass the coldest temperatures ever recorded on the earth’s surface. The lowest measured air temperature on earth is −89.2 °C (−129 F) on 23 July 1983, observed at Vostok Station in Antarctica, but new data published in Geophysical Research Letters this week, has found that some 100 different locations on the East Antarctic Plateau reached temperatures of -98° C (-144° F) during the Antarctic polar night between 2004–2016. A team from the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder have...
  • Bedrock in West Antarctica rising at surprisingly rapid rate

    The unexpectedly fast rate of the rising earth may markedly increase the stability of the ice sheet against catastrophic collapse due to ice loss, scientists say. Moreover, the rapid rise of the earth in this area also affects gravity measurements, which implies that up to 10 percent more ice has disappeared in this part of Antarctica than previously assumed. Researchers led by scientists at The Ohio State University used a series of six GPS stations (part of the POLENET-ANET array) attached to bedrock around the Amundsen Sea Embayment to measure its rise in response to thinning ice. The "uplift rate"...

    In the future, seas will rise far higher than they are today. The question is whether it happens quickly or slowly. There's enough ice stacked on top of Antarctica to raise seas around the globe by almost 200 feet. While it takes time for major changes to occur with that much ice, Antarctica is melting faster than we thought, according to a study recently published in the journal Nature. The melting rate has been speeding up significantly in recent years. Between 1992 and 2017, Antarctica lost more than 3.3 trillion tons of ice, causing sea levels around the globe to...

Just beyond the northwest edge of the vast Greenland Ice Sheet, Northwestern University researchers have discovered lake mud that beat tough odds by surviving the last ice age. The mud, and remains of common flies nestled within it, record two interglacial periods in northwest Greenland. Although researchers have long known these two periods -- the early Holocene and Last Interglacial -- experienced warming in the Arctic due to changes in Earth's orbit, the mix of fly species preserved from these times shows that Greenland...

    About 74,000 years ago, the Toba volcano on the Indonesian island of Sumatra erupted with catastrophic force. Estimated to be 5,000 times larger than the 1980 eruption of Mount St. Helens, it is believed to be the largest volcanic event on Earth in the last 2 million years. Toba spewed enough lava to build two Mount Everests, it produced huge clouds of ash that blocked sunlight for years, and it the left behind a crater 31 miles (50 kilometers) across. The volcano even sent enough sulphuric acid into the atmosphere to create acid rain downpours in the Earth's polar regions,...

    Bone with bullet hole found by Russians in 1946 came from an unknown woman, not the German leader Tests on skull fragment cast doubt on Adolf Hitler suicide In countless biographies of Adolf Hitler the story of his final hours is recounted in the traditional version: committing suicide with Eva Braun, he took a cyanide pill and then shot himself on 30 April 1945, as the Russians bombarded Berlin. Some historians expressed doubt that the Führer had shot himself, speculating that accounts of Hitler's death had been embellished to present his suicide in a suitably heroic light. But a fragment...

    French researchers claim to have put an end to conspiracy theories surrounding the death of Adolf Hitler, after a study of his teeth proved he definitely died after taking cyanide and shooting himself in the head in Berlin in 1945. The researchers reached their conclusion after they were given rare access to fragments of Hitler’s teeth which have been held in Moscow since the end of World War II. "The teeth are authentic, there is no possible doubt. Our study proves that Hitler died in 1945," said professor Philippe Charlier. "We can stop all the conspiracy theories about Hitler. He...

    Huge icebergs could be towed from Antarctica to Cape Town in a bid to solve South Africa's worst drought in a century. Marine salvage experts are floating the plan to tug the icebergs to the region after its seen the worst water shortage in decades. Salvage master Nick Sloane told Reuters news agency he was looking for government and private investors for a scheme to guide huge chunks of ice across the ocean, chop them into a slurry and melt them down into millions of litres of drinking water. "We want to show that if there is no other source...

    THE lost city of Atlantis may have finally been uncovered after a structure was spotted poking through the ice of Antartica on Google Earth.Conspiracy theorists have long searched for the mythical city, which was first written about by philosopher Plato. Some believe it was a real place and was once the ruling power of the world before a natural disaster sank the entire island into the sea. But one man – Graham Maple, who runs YouTube channel Conspiracy Depot – may have brought an end to all the speculation after his amazing spot on the web mapping site. He believes...
  • Antarctic snowfall increasing, study finds

    Snowfall across the great white continent of Antarctica is increasing, according to a study released this week by an international team led by the British Antarctic Survey. The team analyzed 79 ice cores from across Antarctica that provide detailed information on how much snow has fallen over hundreds of years, and it found a 10% increase in snowfall over the past two centuries. This contradicts studies that found that Antarctic snowfall has remained largely constant over the past several decades to centuries. But those studies analyzed only a few ice cores, whereas this comprehensive look at the continent gives a...

    A favorite technique of the propagandists of the Global Warming scare is to find cute and cuddly creatures that they can claim are “threatened” by global warming. For years, an iconic picture of a polar bear on an ice floe was used to frighten children into clutching their stuffed teddy bears and demanding Mommy and Daddy act to save them. But the bloom started coming off that rose when a scientist who had made population estimates that allowed the bears to be classified as threatened admitted that the estimates were: “A guess to satisfy public demand” but wrapped in...

    Scientists were surprised by the results of their study. ___________________________________________________________________________________________________________________________ In November, scientists from New Zealand used a hot water drill to go deep into Antarctica's Ross Ice Shelf. The shelf, which can be up to 10,000 feet thick, is the largest of several that hold back West Antarctica's massive amounts of ice. If these were to collapse, global sea level would rise by ten feet. Drilling a hole and lowering a camera and thermometer inside is a way for researchers to understand the history of the shelf, and what is happening to it now. In measuring the temperature and...
