We shouldn’t forget – Antarctic ice is also melting

Zach Labe is always a good source of graphics summarizing collections of data on our changing climate Here he shows the melting of sea ice around Antarctica. The horizontal line shows the average extent of sea ice over the era of satellite measurements (beginning in 1978). The red line shows how much smaller extent of sea ice this January so far.
