Here’s when powerful people have trouble making a decision

Although powerful people often tend to decide and act quickly, they become more indecisive than others when the decisions are toughest to make, a new study suggests. Researchers found that when people who feel powerful also feel ambivalent about a decision – torn between two equally good or bad choices – they actually have a harder time taking action than …

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 …

Sea-level rise could nearly double over earlier estimates in next 100 years

A new study from climate scientists Robert DeConto at the University of Massachusetts Amherst and David Pollard at Pennsylvania State University suggests that the most recent estimates by the Intergovernmental Panel on Climate Change for future sea-level rise over the next 100 years could be too low by almost a factor of two. Details appear in the current issue of Nature. …

Greenland’s darkening ice is melting faster

A dusty film of pollution is muting the reflective whiteness of Greenland’s pristine icecap and making it vulnerable to accelerated melting rates. Greenland is getting darker. Climatology’s great white hope, the biggest block of ice in the northern hemisphere, is losing its reflectivity. According to new research, the island’s dusty snows are absorbing ever more solar radiation, which is likely …

TIM BISSELL – 10 Secret CIA Prisons You Do Not Want To Visit

The US Central Intelligence Agency has, according to multiple investigative reports from both mainstream media outlets and human rights organizations, operated numerous “black sites” across the world. These locations, according to the reports, are secret prisons used to house “ghost prisoners.” Those sent to these places are held captive without being charged with any crime and are not allowed any …

James Wilt – There Is a New Climate Change Disaster Looming in Northern Canada

Of all the climate change issues that have been melodramatically dubbed a “carbon bomb” in recent years—tar sands projects in Alberta, catastrophic wildfires in Indonesia, holes in Australia’s seagrass meadows—it seems the thawing of permafrost in the Arctic is most likely to live up to the hype. There’s a staggering amount of methane and carbon dioxide, like hundreds of gigatons …

Jessica Orwig – Sending humans to Mars could uncover a disturbing truth to one of life’s greatest mysteries

This version of a self-portrait of NASA’s Curiosity Mars rover at a drilling site called “Buckskin” is presented as a stereographic projection, which shows the horizon as a circle. The MAHLI camera on Curiosity’s robotic arm took dozens of component images for this selfie on Aug. 5, 2015. If humankind successfully lands people on the surface of Mars, we could discover …

Tim Radford – West Antarctic ice cascades towards crisis

Just a few more decades of ocean warming would be enough to destabilise the relatively small region of ice by the Amundsen Sea − starting a cascade of slipping and sliding that would tip enough ice into the ocean to raise sea levels by three metres. The loss of ice would continue for centuries. Two scientists at the Potsdam Institute …

New Study Shows Antarctic Melting Approaching ‘Unstoppable’ Tipping Point

‘What we call the eternal ice of Antarctica unfortunately turns out not to be eternal at all,’ says lead author of new study A new study published Monday warns that “unstoppable” melting in West Antarctica could make a three-meter increase in sea level “unavoidable.” According to researchers at Germany’s Potsdam Institute for Climate Impact Research, the vulnerable Amundsen Sea sector …
