How much Ice is being lost in the Antarctic?
By using satellite data over a period of four decades it becomes possible to work out how much ice is being lost in the Antarctic. So how much is being lost? The answer comes via a new study that has just been published in PNAS on 22nd January 2019. Let’s take a look to see … Read more
Record Low Sea Ice in Antarctica
Since the 1970s we have a very accurate measurement via satellites of what is going on with the extent of the sea ice in both the Arctic and also the Antarctic. It is actually possible to look even further back by using ships records, for example Cook encountered a wall of sea ice when searching … Read more
New Study: Moderate warming will lead to huge increases in Sea level
A new study has been published in nature that reveals some very worrying data. Looking back to see what has actually happened in the past is a good way to work out what is coming as we warm the planet, and it is that data that reveals the degree of warming required to melt vast … Read more
Study: East Antarctica ice sheet is becoming unstable
In the East of Antarctica there are two ice sheets named “Totten” and also “Moscow University”. These together contain enough ice to raise sea level by as mush as five meters. There is a new study that has been published that used the Gravity Recovery and Climate Experiment (GRACE) satellites to measure what is currently … Read more
