An Antarctic ice shelf has disappeared: scientistsWASHINGTON (Reuters) - One Antarctic ice shelf has quickly vanished, another is disappearing and glaciers are melting faster than anyone thought due to climate change, U.S. and British government researchers reported on Friday.
They said the Wordie Ice Shelf, which had been disintegrating since the 1960s, is gone and the northern part of the Larsen Ice Shelf no longer exists. More than 3,200 square miles (8,300 square km) have broken off from the Larsen shelf since 1986.
Climate change is to blame, according to the report from the U.S. Geological Survey and the British Antarctic Survey, available at http://pubs.usgs.gov/imap/2600/B
"The rapid retreat of glaciers there demonstrates once again the profound effects our planet is already experiencing -- more rapidly than previously known -- as a consequence of climate change," U.S. Interior Secretary Ken Salazar said in a statement.
"This continued and often significant glacier retreat is a wakeup call that change is happening ... and we need to be prepared," USGS glaciologist Jane Ferrigno, who led the Antarctica study, said in a statement.
"Antarctica is of special interest because it holds an estimated 91 percent of the Earth's glacier volume, and change anywhere in the ice sheet poses significant hazards to society," she said.
In another report published in the journal Geophysical Letters, the National Oceanic and Atmospheric Administration reports that ice is melting much more rapidly than expected in the Arctic as well, based on new computer analyses and recent ice measurements.
The U.N. Climate Panel projects that world atmospheric temperature will rise by between 1.8 and 4.0 degrees Celsius because of emissions of greenhouse gases that could bring floods, droughts, heat waves and more powerful storms.
As glaciers and ice sheets melt, they can raise overall ocean levels and swamp low-lying areas.
And this from 2006, The United Nation’s Long Shadow report:
This report aims to assess the full impact of the livestock sector on environmental problems, along with potential technical and policy approaches to mitigation. The assessment is based on the most recent and complete data available, taking into account direct impacts, along with the impacts of feed crop agriculture required for livestock production.
The livestock sector emerges as one of the top two or three most significant contributors to the most serious environmental problems, at every scale from local to global. The findings of this report suggest that it should be a major policy focus when dealing with problems of land degradation, climate change and air pollution, water shortage and water pollution, and loss of biodiversity.
Livestock’s contribution to environmental problems is on a massive scale and its potential contribution to their solution is equally large. The impact is so significant that it needs to be addressed with urgency. Major reductions in impact could be achieved at reasonable cost.

And where is Barack "I like Barbeque" Obama? Probably at some fancy dinner cramming cadavers in his selfish corpse-hole like the capitalist blood-sucking puppet he is.
