British Antarctic snowfall study deepens the mystery of global warming

Another mystery in ‘settled’ climate science. Experts now say they ‘acknowledge that the Antarctic is an important factor in climate change, but still a poorly understood one’. Snowfall is arriving on the land mass while ice is drifting into the sea – as usual in that part of the world. What is needed is accurate data before reaching for the alarm bell.

Previous climate change models predicted that global sea levels would rise by a meter by the year 2100 due in part to melting Antarctic ice, but those estimates have proven to be flawed.

Over the past century, the Antarctic has gone from being a vast Terra Incognita to a continent-sized ticking time bomb: according to NASA, Antarctica has lost “approximately 125 gigatons of ice per year [between 2002 and 2016], causing global sea level to rise by 0.35 millimeters per year.”

If global temperatures continue to rise, Antarctica’s melting glaciers will cause the oceans to rise, as well as drastic changes in climate. However, new research by British Antarctic Survey shows that Antarctica paradoxically saw a 10 percent increase in snowfall over the last 200 years.

The research comes from 79 ice core samples collected across the continent, and the estimated increase in snow represents about 272 giga tonnes of water.

“There is an urgent need to understand the contribution of Antarctic ice to sea-level rise and we use a number of techniques to determine the balance between snowfall and ice loss,” said lead author on the study, Dr. Liz Thomas.

“When ice loss is not replenished by snowfall then sea level rises…Our new results show a significant change in the surface mass balance [from snowfall] during the 20th century. The largest contribution is from the Antarctic Peninsula, where the annual average snowfall during the first decade of the 21st century is 10 percent higher than at the same period in the 19th century.”

The increase in snowfall doesn’t contradict previous estimates of ice loss around Antarctica’s coast, but it does make the picture more complicated.

    How do they get ‘continent-sized ticking time bomb’ out of ‘poorly understood’?

    Reblogged this on Climatism and commented:
    “Theory predicts that, as Antarctica warms, the atmosphere should hold more moisture and that this should lead therefore to more snowfall. And what we’re showing in this study is that this has already been happening,” Dr Thomas said.”

    Contradictory to what the IPCC brains trust assured us in their 2001 report:

    Global sea area is 510,000,000 km2.
    Antarctica area is 14,000,000 km2
    Ratio Antarctica to sea area is 36.4:1lost ice
    Claimed sea level rise is 0.35 mm per year divided by 36.4 equals 0.0097mm of lost ice level per year.
    Less than 10 microns, you would have trouble measuring that with a CMM.

    What the hell are they measuring the ice level with?

    Have the climate models ever got a prediction right? If not why do they keep on relying on them?

    I also wonder if the 90 odd volcanoes under the ice have more to do with the ice melt than any supposed CO2 induced ‘global warming’.

  5. erl happ says:

    In Antarctica the temperature never ever rises above freezing point.

  6. oldbrew says:

    Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km (1.2 mi; 6,200 ft) in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula

    http://en.wikipedia.org/wiki/Antarctica

    Note the ice thickness.

    oh come on I made 2-3 posts here with nothing but facts 18 hrs ago and nothing turns up. are you piching comments that can be posted here again

    [mod] off-topic plugs for wind co’s aren’t comments

  8. stpaulchuck says:

    0.35mm … in 100 years that would be 35mm or about one and a third inch. I think we can deal with that.

    Big increase in Antarctic snowfall
    By Jonathan Amos
    BBC Science Correspondent
    9 April 2018

    Some 272 billion tonnes more snow were being dumped on the White Continent annually in the decade 2001-2010 compared with 1801-1810.

    This yearly extra is equivalent to twice the water volume found today in the Dead Sea.

    Put another way, it is the amount of water you would need to cover New Zealand to a depth of 1m.

    http://www.bbc.co.uk/news/science-environment-43691671

    All that snow had to come from somewhere.

    So the Antarctic isn’t melting as “projected” by the all-powerful computerised climate models.
    This observation adds to a long list of climate model failures.
    I wouldn’t trust them to predict that the sun will rise tomorrow- they are that cr@p.

    Similar issues in Greenland?

    Snowfall patterns may provide clues to Greenland Ice Sheet
    April 10, 2018

    To better understand and anticipate changes in sea level rise, scientists have sought to quantify how much snow falls on the ice sheet in any given year, and where, since snow is the primary source of the ice sheet’s mass. This has proven to be a challenging problem.

    So: ‘may provide clues’, ‘challenging problem’ – still much to learn it seems. Alarmists should pipe down.

    [mod] off-topic plugs for wind co’s aren’t comments
    no it was not linking to any wind plug one was to Canadian Nuclear info PDF about LC of generation
    Another was to a manufacturers independent document concerning Life Cycle Assessment

    But never mind if you do not want truth published.

    Ford: the topic is Antarctic snowfall.

  14. thefordprefect says:

    ok apologies this should have been posted in earlier thread

    [reply] no worries

    The up/down/”back” radiation greenhouse gas energy loop of the radiative greenhouse effect theory is pencil on paper, a spreadsheet cell, a “what if” scenario and NOT a physical reality.

    Without this GHG energy loop, radiative greenhouse theory collapses.

    Without RGHE theory, man-caused climate change does not exist.

    And with a snap of the fingers and “Presto!!” the bazillion dollar global climate change fantasy is suddenly unemployed.

    Must be why nobody wants to talk about this possibility, not newsworthy enough.
