Ice is found all over the world in a wide variety of forms. More than simply frozen water, the various forms of ice tell the story of their environment as they change with the seasons and show trends of the changing climate on Earth. Scientists study core samples pulled from the depths of large ice formations, such as ice caps and glaciers, to uncover how the local climate has changed over hundreds of years and to help predict how climate will change in the future, said Melissa Hage, an environmental scientist and assistant professor at Oxford College of Emory University in Georgia. Here we define the common terms that describe the various types of ice formations found around the world. Glaciers Glaciers are large, freshwater ice masses on land that are formed from falling snow that eventually becomes so heavy that it's compressed into ice, according to the National Snow and Ice Data Center (NSIDC). Glaciers range in size from about the length of a football field (120 yards, or 110 … [Read more...] about What Are the Different Types of Ice Formations Found on Earth?
Melting of ice caps
Dec 26, 12:09 AM EST Newsletter Signup BusinessTechnologyWorldNationalMedia & CultureOpinionSportsLuxury Technology By Micah Ong 12/23/18 AT 9:00 PM Antarctic ice sheets have melted and raised sea levels by up to 30 feet around the world tens of thousands of years ago. However, new research suggests that another ice sheet may collapse soon and cause another global flood.Geologist Anders Carlson of Oregon State University and his team found that the Antarctic ice sheet that melted 125,000 years ago and inundated huge swaths of what had been dry land disappeared under climate conditions that were similar to what we are experiencing today, according to USA Today. The only difference is that the ancient ice sheet melted due to natural climate change, but the future global flood, if it happens, would be caused by man-made global warming.The findings were announced earlier this December at an American Geophysical Union meeting in Washington, D.C.Boston College … [Read more...] about Ancient Antarctic Ice Melting Could Raise Sea Level By 30 Feet, Submerge Islands
CLIMATE change has forced the melting of Greenland's mile-thick ice sheet into 'overdrive', threatening to boost global sea levels to dangerous levels. The enormous sheet, which covers an area two and a half times that of the United Kingdom, is dumping more melted ice into the oceans than at any point during the past 400 years, according to a new study. Rising sea levels pose a host of catastrophic risks to the planet, and the new study serves as a stark warning that without action against climate change, humanity is headed for a future 'where food shortages, floods and fires are part of our everyday reality', scientists warned. They added that Greenland's dramatic melting was directly linked to the greenhouse gases belched into Earth's atmosphere since the beginning of the industrial revolution. "From a historical perspective, today's melt rates are off the charts, and this study provides the evidence to prove it" said Sarah Das, a glaciologist at Woods Hole Oceanographic … [Read more...] about Climate change in ‘OVERDRIVE’ as experts warn Greenland ice melt now ‘off the charts’
PUBLISHED: 13:01 26 November 2018 | UPDATED: 13:01 26 November 2018 James Carr The Met Office has warned rising sea levels could devastate coastal towns and farmland between Kings Lynn and Cambridge. Photo: Mike Page. ©Mike Page, All Rights Reserved A large area of land stretching between King’s Lynn and Cambridge will be destroyed as rising seas levels flood 1.7 million homes and devastate coastal communities, a chastening Met Office report has concluded. The UK Climate Projections (UKCP) 2018 report has found UK sea levels are likely to increase by 3-4ft by 2100 and 10ft by 2300 due to greenhouse gas emissions warming the earth.The change will not only impact coastal communities but could spread inland also - with the majority of farmland between King’s Lynn and Cambridge falling below sea level and turning to marshes. A range of scenarios are included in the report depending on the different rates of greenhouse gas emissions in the … [Read more...] about Vast swathe of land between King’s Lynn and Cambridge to be lost as sea rises, Met Office warns
HUMANS need to settle on Mars as a "plan B" – or we risk going the way of the dinosaurs. That's the belief of top theoretical physicist Michio Kaku, who said Mars is one of our best hopes of avoiding "extinction". According to the American science titan, "99.9% of all life forms" become fossils – and "disappear off the face of the Earth". Humanity risks the same fate if we don't invest in space travel, and find a way to settle on Mars. "Look at the dinosaurs," Kaku said, speaking on ABC's Late Night Live. "The dinosaurs did not have a space program, and that's why they are not here today to talk about it." It's easy for humans to think we'll buck the trend and survive through any cataclysmic event. But Kaku is concerned that the only real way to avoid the total wipe-out of humanity is to colonise Mars. "Extinction is the norm," he explained. "We think of Mother Nature as being warm and cuddly, which is partly true. "But nature is merciless when it comes to wiping out … [Read more...] about Humans could MELT ice on Mars to make it habitable – and save us from ‘dinosaur’ extinction, says top physicist
