Paul Homewood: The point is admitted that it is actually warm water at a depth of about 300m which is undercutting the glacier. But it is physically impossible for greenhouse gases to have any measurable effect at all on waters at such a depth...
In reality, the scientists who wrote this study do not have a clue whether the retreat of the Denman is anything new or not, or whether the deep ocean temperatures are any warmer than before 1979. Or whether what they are observing is just a natural process.
They claim that since 1979, 250 billion tonnes of ice has been lost, equivalent to 0.5mm of sea-level rise. In other words, 1.3mm/C, hardly cataclysmic. They then go on to talk about a potential loss of 540 trillion tonnes, raising sea levels by 5 feet. Yet at current rates, it would take 2160 years for this to occur! As always with these sorts of studies, the authors refuse to say how long all this will take to happen.
WMO cites media as source! The WMO website itself is citing the media as its source, writing: “Media reports say that researchers logged a temperature of 20.75°C. Mr Cerveny cautioned that it is premature to say that Antarctica has exceeded 20°C for the first time.”
Thermometer data show only 16°C! But according to German Facebook site Klima.Wissen here and its readers, the “all-time record high reading appears to have its origins from the AFP news agency. It was then picked up by the always climate sensational The Guardian. But now the whole story is beginning to appear as just big sensational hoax.
