So there has been a supervolcano under Antartica the whole time

    Oh God, I'm holding it hurts but it's for the good of the Earth. Ugh...
  2. Just walk around with balloon pants, everytime you fart it fills up the balloon, later when you get home you can use the gas to cook your hamburger patties.

    I say this in jest, but i wouldnt be surprised if in 100 years there is fart sharing, and a fart sharing app

    You deleted part of the post.

    From the discussion section of the paper:

    "Currently, the WAIS may be undergoing another such wholesale retreat, as ice in the Pacific facing sector has consistently been retreating from the time of the earliest aerial and satellite observations (Rignot 2002; McMillan et al. 2014; Mouginot et al. 2014). We do not consider it likely that volcanism has played a significant role in triggering the current retreat, for which there is compelling evidence that the forcing has initiated from the margins (Turner et al. 2017), but we do propose that subglacial volcanism has the potential to influence future rates of retreat by (1) producing enhanced basal melting that could impact upon basal ice motion and (2) providing edifices that may act to pin retreat."

    You are always going to learn more about your planet, but what you should know is that you do have ultimate control over what it is. Antarctica is fine.

    It also doesn't explain shit about the ice melting on the north pole. Those glaciers on Iceland are near plenty of volcanoes too, yet its clear that is not what's melting the glaciers.

    If humans had the same digestion system as cows there would be sense in worrying about human farts. But yeah, wether you like to hear it or not: our beef consumption puts a ridiculous weight on our environment. Cows produce lots of methan. More than humans ever will (you may be an exception :p)

    In regards to the car comment: yes, their pollution adds to the problem, but airplanes are far far worse in their totality.

    West Antarctic Ice Sheet loss over the last 11,000 years seen in new study
    Results shed new light on what's happening today

    Date: July 5, 2017
    Source: British Antarctic Survey
    Wind-driven incursions of warm water forced the retreat of glaciers in West Antarctica during the past 11,000 years, a new report explains. These new results enable researchers to better understand how environmental change may impact future sea-level rise from this climate-sensitive region.


    "Data collected over the last 20 years have shown that the present ice loss in West Antarctica results from the relatively warm water from the deep ocean flowing on to the shallow continental shelf. This warm water reaches the coastline in places, where it triggers substantial melting of the floating parts of glaciers and leads to thinning of the ice upstream."

    "Co-author Dr James Smith, a marine geologist at BAS, says: "Our data also reveal a more recent history of the WAIS. A shift in the wind direction during the 1940s caused renewed upwelling of warm deep water on to the shelf. This has continued ever since and is responsible for the ice loss we are observing today and over the last few decades.""

    An article about Kelvin waves.

    Stronger winds heat up West Antarctic ice melt
    Strengthening winds in the East Antarctic generate Kelvin waves that lead to increasing melting along the West Antarctic Peninsula.

    "It is this combination of available warm water offshore, and a transport of this warm water onto the shelf, that has seen rapid ice shelf melt along the West Antarctic sector over the past several decades," said lead researcher Dr Paul Spence.

    "We always knew warm water was finding its way into this area but the precise mechanism has remained unclear. That remote winds on the opposite side of Antarctica can cause such a substantial subsurface warming is a worrying aspect of the circulation at the Antarctic margin."

    The changes in the Antarctic coastal winds, particularly along East Antarctica, might themselves be related to climate change. This is because as Earth warms the strong westerly winds associated with storms over the Southern Ocean contract toward the poles, in turn changing the winds near the Antarctic continent.

    And this will obviously change everything, tipping the balances around the globe.

    To make it more complex (or not), times are changing due to earth's position in the Milky other words the earth is very slowly turning around...very slowly that is!
