Giant Crack in Antarctica About to Spawn New York-Size Iceberg

With a gargantuan crack slowly splitting it apart, Antarctica‘s fastest-melting glacier is about to lose a chunk of ice larger than all of New York City, scientists say. (Also see “Manhattan-Size Ice Island Cracks in Half.”) The crevasse stretches 19 miles (30 kilometers) long and up to 260 feet (80 meters) wide, as shown in [...]

Rivers of Melting Ice Mapped in Antarctica

The first-ever map of how Antarctica’s ice is moving across that continent has been created by researchers at the University of California, Irvine. The map, along with an associated animation (below) developed by NASA, reveals that ice is flowing fastest in coastal ice shelves and their tributaries, shown in this illustration in bright purple and [...]

Worst ever carbon emissions leave climate on the brink

Greenhouse gas emissions increased by a record amount last year, to the highest carbon output in history, putting hopes of holding global warming to safe levels all but out of reach, according to unpublished estimates from the International Energy Agency. The shock rise means the goal of preventing a temperature rise of more than 2 [...]

New warning on Arctic sea ice melt

Scientists who predicted a few years ago that Arctic summers could be ice-free by 2013 now say summer sea ice will probably be gone in this decade. The original prediction, made in 2007, gained Wieslaw Maslowski’s team a deal of criticism from some of their peers. Now they are working with a new computer model [...]

Peak Oil and a Changing Climate

The scientific community has long agreed that our dependence on fossil fuels inflicts massive damage on the environment and our health, while warming the globe in the process. But beyond the damage these fuels cause to us now, what will happen when the world’s supply of oil runs out? In a new video series from [...]

FRENCHMAN’S PEAK – A DIFFERENT WORLD

Recently on a trip to Esperance on Western Australia’s southern most coast, I took a day to visit Cape Le Grand National Park and Frenchman’s Peak, just over 50 kilometres east of Esperance. Named by the French in 1792 the Peak stands 262 metres above sea level. At the base of the impressive rock formation, [...]

We are entering a new climate era, where the new norm is unpredictable change.

Lester Brown of the Earth Policy Institute and Author of Plan B 4.0: Mobilizing to Save Civilization We are entering a new era, one of rapid and often unpredictable climate change. In fact, the new climate norm is change. The 25 warmest years on record have come since 1980. And the 10 warmest years since [...]

Arctic Ice in Death Spiral

Greenhouse Neutral Foundation comment – This report foreshadows a very grim future for all. We have no further time to waste in de-carbonizing our global activities. We must gather together as a single voice and demand our political masters’ act now! UXBRIDGE, Sep 20 (IPS) – The carbon dioxide emissions from burning fossil fuels have [...]

Ocean Changes May Have Dire Impact on People

The first comprehensive synthesis on the effects of climate change on the world’s oceans has found they are now changing at a rate not seen for several million years. In an article published June 18 in Science magazine, scientists reveal the growing atmospheric concentrations of man-made greenhouse gases are driving irreversible and dramatic changes to [...]

Report warns of global warming costs

Health problems require agencies to take all-hands-on-deck approach, expert says The health risks of global climate change read like a chapter out of the Book of Revelation: plagues from mosquitoes and other insects; floods and droughts that cause sickness and mental anguish; food-borne scourges and malnutrition. In a report released recently by federal scientists, led [...]
