Oldest Fossils On Earth & Alien Life

The discovery of the 3.7 billion-year-old fossil pushes back earliest life on Earth by 220 million years, raising chances that Mars once had life, when both planets were similar.

OSLO, Aug 31 - The earliest fossil evidence of life on Earth has been found in rocks 3.7 billion years old in Greenland, raising chances of life on Mars aeons ago when both planets were similarly desolate, scientists said on Wednesday....

“This indicates the Earth was no longer some sort of hell 3.7 billion years ago,” lead author Allen Nutman, of the University of Wollongong, told Reuters of the findings that were published in the journal Nature.

“It was a place where life could flourish.” ...

Greenland Is Melting Away

     On the Greenland Ice Sheet — The midnight sun still gleamed at 1 a.m. across the brilliant expanse of the Greenland ice sheet. Brandon Overstreet, a doctoral candidate in hydrology at the University of Wyoming, picked his way across the frozen landscape, clipped his climbing harness to an anchor in the ice and crept toward the edge of a river that rushed downstream toward an enormous sinkhole.

If he fell in, “the death rate is 100 percent,” said Mr. Overstreet’s friend and fellow researcher, Lincoln Pitcher.

But Mr. Overstreet’s task, to collect critical data from the river, is essential to understanding one of the most consequential impacts of global warming. The scientific data he and a team of six other researchers collect here could yield groundbreaking information on the rate at which the melting of the Greenland ice sheet, one of the biggest and fastest-melting chunks of ice on Earth, will drive up sea levels in the coming decades. The full melting of Greenland’s ice sheet could increase sea levels by about 20 feet. [...]

West Antarctica Warming Twice As Fast As Previously Believed

OSLO, Dec 23 (Reuters) - West Antarctica is warming almost twice as fast as previously believed, adding to worries of a thaw that would add to sea level rise from San Francisco to Shanghai, a study showed on Sunday.

Annual average temperatures at the Byrd research station in West Antarctica had risen 2.4 degrees Celsius (4.3F) since the 1950s, one of the fastest gains on the planet and three times the global average in a changing climate, it said.

The unexpectedly big increase adds to fears the ice sheet is vulnerable to thawing. West Antarctica holds enough ice to raise world sea levels by at least 3.3 metres (11 feet) if it ever all melted, a process that would take centuries.

"The western part of the ice sheet is experiencing nearly twice as much warming as previously thought," Ohio State University said in a statement of the study led by its geography professor David Bromwich.

The warming "raises further concerns about the future contribution of Antarctica to sea level rise," it said. Higher summer temperatures raised risks of a surface melt of ice and snow even though most of Antarctica is in a year-round deep freeze.

Low-lying nations from Bangladesh to Tuvalu are especially vulnerable to sea level rise, as are coastal cities from London to Buenos Aires. Sea levels have risen by about 20 cms (8 inches) in the past century.

      The vast ice sheets that cover Greenland and Antarctica have begun melting and sliding into the ocean as heat-trapping greenhouse gases continue to build in the atmosphere. How much and how fast the ice is disappearing, however, has been poorly understood, because the satellites that measure it haven’t always agreed. But a report published Thursday in Science has cleared up much of the uncertainty.

A team of no fewer than 47 scientists from 36 laboratories, looking at data from 10 different satellites, has come up with numbers everyone is on board with: between 1992 and 2011, Greenland has lost an average of 152 billion metric tons of ice per year, while Antarctica has shed 71 billion, contributing 11 millimeters to the rise in sea level over that period — about a fifth of the total (the rest has come from from seawater expanding as it warms and from melting mountain glaciers).

“The new estimates,” lead author Andrew Shepherd, of the University of Leeds, said in a press conference, “are the most reliable to date. They end 20 years of uncertainty.”

The estimates don't change projections about what’s likely to happen for the rest of this century. Scientists’ best estimate is that that the ocean, which has risen an average of 8 inches since 1900, should rise another 3 feet or so by 2100. . . .
