The majestic snow-capped summits of Africa's Mount Kilimanjaro are melting quickly "” so quickly, in fact, that the ancient mountain's ice sheet could completely disappear within 20 years, says a US study released on Monday. In the study, published in the journal Proceedings of the National Academy of Sciences, climatologists reported that the ice cap crowning Kilimanjaro's peak shrank by some 85 in the nearly hundred years between 1912 and 2007.  Even more disturbing, ...

Researchers spent two months this summer high in the Peruvian Andes and brought back two cores, the longest ever drilled from ice fields in the tropics. Ohio State glaciologist Lonnie Thompson said that this latest expedition focused on a yet-to-be-named ice field 5,364 meters (17,598 feet) above sea level in the Cordillera Blanca mountain range. The researchers hiked to a col, or saddle, between two adjacent peaks "“ Hualcán and Copa "“ set up camp and used a ground sensing...

In 2007 alone, it lost volume equivalent to draining San Francisco Bay every week Not that long ago "“ the blink of a geologic eye "“ global temperatures were so warm that ice on Greenland could have been hard to come by. Today, the largest island in the world is covered with ice 1.6 miles thick. Even so, Greenland has become a hot spot for climate scientists. Why? Because tiny bubbles trapped in the ice layers may help resolve a fundamental question about global warming: how fast...

An analysis of sediment cores indicates that biological and chemical changes occurring at a remote Arctic lake are unprecedented over the past 200,000 years and likely are the result of human-caused climate change, according to a new study led by the University of Colorado at Boulder. While environmental changes at the lake over the past millennia have been shown to be tightly linked with natural causes of climate change -- like periodic, well-understood wobbles in Earth's orbit -- changes...

Scientists say that a new historical record of carbon dioxide levels is showing that current political targets on climate may be "playing with fire." The researchers used ocean sediments to map CO2 levels dating back to 20 million years ago. Levels similar to those now commonly regarded as adequate to tackle climate change were linked to sea levels 80-130 ft higher than today. The researchers noted in the journal Science that this extends knowledge of the link between CO2 and climate back...

Scientists are taking a more in-depth view of how climate change could affect Antarctica's ice, and how even a small change in temperature could lead to a global rise in sea levels. "If you're going to have even a few meters it will change the geography of the planet," Rajendra Pachauri, head of the U.N.'s Intergovernmental Panel on Climate Change (IPCC) told Reuters. "Greenland and Antarctica are two huge bodies of ice sitting on land that could really have very serious implications for the...

Will all of the ice on Greenland melt and flow out into the sea, bringing about a colossal rise in ocean levels on Earth, as the global temperature rises? The key concern is how stable the ice cap actually is and new Danish research from the Niels Bohr Institute at the University of Copenhagen can now show the evolution of the ice sheet 11,700 years back in time "“ all the way back to the start of our current warm period. The results are published in the esteemed journal Nature....

Sediment cores show the Arctic has been warmer during the past decade than during any 10-year period in the last 2,000 years, scientists said. The study provides a clear example of how increased greenhouse gases are now changing our climate, said Caspar Ammann of the National Center for Atmospheric Research in Boulder, Colo. Ammann and his team studied sediment cores from lakes, tree rings and ice cores, all of which showed the Arctic has been warming since about 1850 -- the beginning of the...

An international team of scientists, led by Denmark, says it set a single-season deep ice core drilling record this summer in Greenland. The researchers, with the University of Colorado at Boulder as the lead U.S. institution, recovered more than a mile of ice core that is expected to help scientists better assess the risks of abrupt climate change in the future. The project, known as the North Greenland Eemian Ice Drilling, is being undertaken by 14 nations led by the University of...

A new 2,000-year-long reconstruction of sea surface temperatures (SST) from the Indo-Pacific warm pool (IPWP) suggests that temperatures in the region may have been as warm during the Medieval Warm Period as they are today.The IPWP is the largest body of warm water in the world, and, as a result, it is the largest source of heat and moisture to the global atmosphere, and an important component of the planet's climate. Climate models suggest that global mean temperatures are particularly...
