Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

PIG Calves a Massive Iceberg

Pine Island glacier (PIG) spawns a huge iceberg in the Antarctic

The iceberg measures about 720 sq km, or eight times the size of Manhattan Island, said a report.

The large crack spreading across the “longest and fastest flowing glacier” in the west Antarctic was first observed in October 2011.

“The PIG is the most rapidly shrinking glacier on the planet,” said a researcher.

“It’s losing more ice than any other glacier on the planet, and it’s contributing to sea level rise faster than any other glacier on the planet.”

The speed of Pine Island Glacier increased by 73 percent between 1974 and  2007. As a result, PIG had a negative mass balance of 46 gigatons per year, that is the glacier system drained more water into the sea than replaced by snowfall, researchers say.
