Here is our 'writing on the wall': the clearest evidence yet that sea temperatures are undermining the Antarctic. Let's not turn a blind eye and follow the mistakes which destroyed the Libyan city of Derna, whose leaders failed to heed their warnings. The total area of missing sea-ice at the height of the southern hemisphere winter is five times the area of the United Kingdom: no-one can justify denial of global warming in the face of this clear evidence. The catastrophic flooding of Derna should therefore be a wake-up call for us all — don't let climate change get out of control. Background music: 'Ether Oar' by The Whole Other Image source: BBC
