NASA Report Points To An Increase In Antarctic Ice
Whilst NASA has been busy flying its Cassini spacecraft through the icy plumes of Saturn’s moon Enceladus, it has also released a report concerning cool activity here on planet Earth. We have featured a lot of news stories in the past year that point to evidence of climate change in the Polar Regions and so it is only right that we also bring you news on the contrary when it appears.
Recent data captured by NASA has shown that, unlike what some scientists believe, the total ice in Antarctica is actually growing rather than shrinking. The report was produced after studies were made of the thickness in the ice sheet between 2001 and 2008. It seems that, although the rate is slowing (down from 112 billion tons per year from 1992 to 2001 to just 82 billion tons from 2003 to 2008) the Antarctic continent is gaining more ice than it is losing. Whilst NASA is in agreement that ice loss is occurring in some regions, the gains measured in the east and interior western parts mean there is an overall increase.
The boost is down to fresh snow being compacted over the years to form ice, but this good news could still have a downside. Scientists have previously predicted that 8% of the yearly rise we see in sea levels is down to glacial melting from Antarctica. However, with these new findings, it begs the question that if the south polar region is actually gaining ice, this increase in sea level must be down to something else.
