Giant Antarctic Pine Island Glacier melting beyond point of no return

Posted in 2014 with tags , , , , , , , , , on January 15, 2014 by MARIE EMMANUELLE QUILICHINI

Antarctica’s Pine Island Glacier, one of the biggest single contributors to world sea-level rise, is melting irreversibly and could add as much as a centimetre to ocean levels in 20 years, according to a study. The glacier “has started a phase of self-sustained retreat and will irreversibly continue its decline”, said Gael Durand, a glaciologist with France’s Grenoble Alps University. Durand and an international team used three different models to forecast the glacier’s future based on the “grounding line”, which is the area under water where the ice shelf – a sea-floating extension of the continent-covering ice sheet – meets land.

This line has receded by about 10 kilometres in the past decade. The grounding line “is probably engaged in an unstable 40km retreat,” said the study, published in the journal Nature Climate Change. A massive river of ice, the glacier by itself is responsible for 20 per cent of total ice loss from the West Antarctic Ice Sheet today. On average, it shed 20 billion tonnes of ice annually from 1992-2011, a loss that is likely to increase up to and above 100 billion tonnes each year, said the study. This is equivalent to 3.5-10 millimetres of global average sea-level rise over the next 20 years.

The global mean sea level rose by 3.2mm in 2010 – itself a near-doubling from the rate of two decades earlier. The European Space Agency said last month that the West Antarctic ice sheet was shedding ice at a much faster rate than before – currently about 150 cubic kilometres a year. Climate scientists are keeping a worried eye on the mighty ice sheets of Greenland and Antarctica, as continued losses could threaten vulnerable coastal cities with dangerously high sea levels. Last year, the United Nations’ climate science body, the Intergovernmental Panel on Climate Change (IPCC) projected sea levels would rise between 26 and 82 centimetres by 2100.

An orange line painted on the condemned house – and Robb Braidwood, Office of Emergency Management Chesapeake, Virginia – shows the usual high water in the area.” A storm is not even necessary , says Braidwood. Heavy rains and winds in the wrong direction at a high enough tide. “

As seawater warms, it expands. This thermal expansion accounts for about a third of the current rise in sea level. The melting of mountain glaciers account for another third.By 2100, it will no doubt raises several centimeters sea level, but no more. The volume of ice mountains remains small enough.

Its contribution is small today but worrying sign, its surface began to melt in the summer. The ice sheet contains enough water to raise sea levels by almost 7.5 m.

The East Antarctica seems fairly stable. However, the warming of the ocean mine parts of the ice sheet of West Antarctica. The future of the cap, such as Greenland, is very uncertain.

Climate Change Report Sees Violent, Sicker, Poorer Future

WASHINGTON (AP) — A leaked draft of an international scientific report forecasts that man-made global warming likely will worsen already existing human tragedies of war, starvation, poverty, flooding, extreme weather and disease.

The Nobel Peace Prize-winning Intergovernmental Panel on Climate Change will issue a report next March on how global warming is already affecting the way people live and what will happen in the future, including a worldwide drop in income. A leaked copy of a draft of the report’s summary appeared online Friday. Governments will spend the next few months making comments about the draft.

The report details specific effects of warming and how countries and people can adapt to some of them. The American scientist who heads the report, Chris Field, says experts paint a dramatic contrast of possible futures.

The Amazon Rain Forest Is Drying Out, Probably Because Of Climate Change

Posted in 2013 with tags , , , , , , , on October 24, 2013 by MARIE EMMANUELLE QUILICHINI

s-AMAZON-RAIN-FOREST-large300

From Becky Oskin, LiveScience staff writer:

The Amazon rain forest’s dry season lasts three weeks longer than it did 30 years ago, and the likely culprit is global warming, a new study finds.

Rain falls year-round in the Amazon, but most of the annual deluge drops during the wet season. (The rainy season’s timing varies with latitude.) Scientists think that a longer dry season will stress trees, raising the risk of wildfires and forest dieback. The forest’s annual fire season became longer as the dry season lengthened, according to the study, published today (Oct. 21) in the journal Proceedings of the National Academy of Sciences.

“The length of the dry season in the southern Amazon is the most important climate condition controlling the rain forest,” Rong Fu, a climate scientist at The University of Texas at Austin’s Jackson School of Geosciences, said in a statement. “If the dry season is too long, the rain forest will not survive.”

The new findings forecast a more parched future for the Amazon rain forest than the climate report released last month by the Intergovernmental Panel on Climate Change (IPCC), the study authors said. The IPCC models predict the Amazon dry season will last three to 10 days longer by 2100.

Solar Physicists think Sun about to enter a “grand minimum”, Chilly Conditions on Earth, The “Little Ice Age”

Posted in 2013 with tags , , , , , , , , , on October 5, 2013 by MARIE EMMANUELLE QUILICHINI

Ice-age

There’s been criticism for the Intergovernmental Panel on Climate Change (IPCC) over its latest AR5 report from many quarters for many reasons. But today there’s new research focusing on one particular aspect of that criticism.

The particular part of the IPCC’s science in question is its accounting for the effects of changes in the Sun on the climate of planet Earth. Many climatologists have long sought to suggest that the effects of solar variability are minor, certainly when compared to those of human-driven CO2 emissions. Others, however, while admitting that the Sun changes only a very little over human timescales, think that it might be an important factor.

This matters because solar physicists think that the Sun is about to enter a “grand minimum”, a prolonged period of low activity.

The current 11-year peak in solar action is the weakest seen for a long time, and it may presage a lengthy quiet period. Previously, historical records suggest that such periods have been accompanied by chilly conditions on Earth – perhaps to the point where a coming minimum might counteract or even render irrelevant humanity’s carbon emissions. The “Little Ice Age” seen from the 15th to the 19th centuries is often mentioned in this context.

Human Influence on Climate is Highly Probable

Posted in 2013 with tags , , , , , , , on September 27, 2013 by MARIE EMMANUELLE QUILICHINI

polarbears

Meeting in Stockholm, experts IPCC unveiled Friday morning, their fifth report on climate. After five more years of work, the experts of the Intergovernmental Panel on Climate Change will worsen their diagnosis on the state of the planet and the impact of global warming.

They predict that the Earth will warm by 0.3 to 4.8 ° C on average by 2100. The sea level should, in turn, from 26 to 82 cm, while the 2007 forecast forecast a rise of 18-59 cm.

The human influence is now ‘highly probable’, which is equivalent to 95% certainty, according to the report. In 2007, this certainty was assessed at 90%.
