Arctic Sea ice
Posted on: July 29, 2015
For many years we have been told of the impact climate change is having on our planet. A shrinking Arctic ice cap is one of the most commonly used pieces of evidence when demonstrating this. However recent analysis has shown, much to the surprise of experts, that the ice cap actually bucked the long-term trend of decline during 2013.
Since satellites began studying the region in the late 1970s, the ice covering in the Arctic has shrunk by 40%. By launching its ‘Cryosat’ satellite in 2010, the European Space Agency has been able to able to better understand the shrinking of the sea ice. Where previously scientists were only able to judge the impact of climate change by the area of ice remaining, now they also receive comprehensive data about how thick the ice is as well.
The satellite's 88 million measurements have been analysed by the Nature Geoscience journal and show that:
- Between 2010 and 2012, the Arctic ice volume fell by 14% - in line with the warming of the climate over recent decades.
- In 2013 the ice volume jumped up by 41%.
- In 2014 th
