Arctic ice melt ‘already affecting weather patterns where you live right now’

The dramatic melting of Arctic ice is already driving extreme weather that affects hundreds of millions of people across North America, Europe and Asia, leading climate scientists have told the Guardian. Severe “snowmageddon” winters are now strongly linked to soaring polar temperatures, say researchers, with deadly summer heatwaves and torrential floods also probably linked. The scientists now fear the Arctic …

This Melting Glacier in Antarctica Could Raise Sea Levels By 11 Feet

The Earth’s climate, it seems, isn’t listening to the politicians that are insisting it’s not warming. The temperature continues to rise incrementally, and the globe’s large glaciers—giant vaults of stored water—continue to melt, releasing into the oceans. The global sea level, due to thermal expansion and glacial melting, continues to rise, building up a head of steam like a train …

Greenland on thin ice?

The ice sheet covering Greenland is four times bigger than California — and holds enough water to raise global sea-level more than twenty feet if most of it were to melt. Today, sea levels are rising and the melting of Greenland is a major contributor. Understanding how fast this melting might proceed is a pressing question for policymakers and coastal …

Greenland ice is melting seven percent faster than previously thought

The same hotspot in Earth’s mantle that feeds Iceland’s active volcanoes has been playing a trick on the scientists who are trying to measure how much ice is melting on nearby Greenland. According to a new study in the journal Science Advances, the hotspot softened the mantle rock beneath Greenland in a way that ultimately distorted their calculations for ice loss …

Melting ice sheet could release frozen Cold War-era waste

Climate change could remobilize abandoned hazardous waste thought to be buried forever beneath the Greenland Ice Sheet, new research finds. Camp Century, a U.S. military base built within the Greenland Ice Sheet in 1959, doubled as a top-secret site for testing the feasibility of deploying nuclear missiles from the Arctic during the Cold War. When the camp was decommissioned in …

Nadia Prupis – Climate Change is Here and Now, Dire NOAA Report Warns

Environmental records of all kinds are being shattered as climate change takes effect in real time, scientists warned on Tuesday. The National Oceanic and Atmospheric Association (NOAA) released its annual State of the Climate report with the dire warning that 2015 was the hottest year on record since at least the mid-to-late 19th century, confirming the “toppling of several symbolic milestones” in …

Tim Radford -Antarctic glacier melt could raise sea level by 3m

LONDON, 21 May, 2016 – One of Antarctica’s great glaciers could become unstable if global warming continues at the present pace. As warm seas wash the ice shelf, the land-based mass of ice could begin to retreat, cross a critical threshold in the present century and then withdraw 300 kilometres inland. In the course of doing so it would spill …

New cause of exceptional Greenland melt revealed

A new study by researchers from Denmark and Canada’s York University, published in Geophysical Research Letters, has found that the climate models commonly used to simulate melting of the Greenland ice sheet tend to underestimate the impact of exceptionally warm weather episodes on the ice sheet. The study investigated the causes of ice melt during two exceptional melt episodes in …

Climate change: Greenland melting tied to shrinking Arctic sea ice

Vanishing Arctic sea ice. Dogged weather systems over Greenland. Far-flung surface ice melting on the massive island. These dramatic trends and global sea-level rise are linked, according to a study coauthored by Jennifer Francis, a research professor in Rutgers University’s Department of Marine and Coastal Sciences. During Greenland summers, melting Arctic sea ice favors stronger and more frequent “blocking-high” pressure …

Melting Greenland ice sheet may affect global ocean circulation, future climate

Scientists from the University of South Florida, along with colleagues in Canada and the Netherlands, have determined that the influx of fresh water from the Greenland ice sheet is “freshening” the North Atlantic Ocean and could disrupt the Atlantic Meridional Overturning Circulation (AMOC), an important component of global ocean circulation that could have a global effect. Researchers say it could …
