Antarctica Loses Nearly Three Trillion Tonnes of Ice in 25 Years

Satellites monitoring the state of the White Continent indicate some 200 billion tonnes a year are now being lost to the ocean as a result of melting.

This is pushing up global sea levels by 0.6mm annually - a three-fold increase since 2012 when the last such assessment was undertaken.

Scientists report the new numbers in the journal Nature.

Governments will need to take account of the information and its accelerating trend as they plan future defences to protect low-lying coastal communities.

The researchers say the losses are occurring predominantly in the West of the continent, where warm waters are getting under and melting the fronts of glaciers that terminate in the ocean.

    Well, I don't think that the current climate change is a problem. I also don't think that a CO2 level of 600 ppm is a problem. The biosphere was quite happy back when it was 6000 ppm. By the rules of your religion, since I am not an 'Alarmist', I must be a 'Denialist'.
    And I am asking, "How much of the recent warming was due to human released CO2? Is it a good or bad thing and what should we do about it either way?"

    That question of human responsibility for climate change has already been answered.

    Really? What was the answer?

    O.T. I don't know why you brought up Trump, but he is not my hero. The best I can say about him is that I think Hillary would have been worse. I am not in the U.S.A. and if I was, I would have voted third party.

    It is a bad thing if you like stability and food. Humanity has pumped a huuuuge amount of CO2 into the atmosphere so the exact numbers aren't that important. 10% or 90% responsible we still shouldn't burn coal/oil/gas if we can help it.

    Suck it up, admit you've been wrong, move forward with renewable energy sources that don't give us as many health problems.

    Cool story bro. Any reason, or just feelz?

    There's some whacky science guy who lists a few reasons why he thinks it it a problem (Agriculture, Health, Polar Melting, Ocean Acidification, Melting Glaciers, Sea Level Rise, etc.) but not feelz unfortunately. But it's just, like, his opinion man.
