Blog 2: Updated NASA Data: Global Warming Not Causing Any Polar Ice Retreat

The article I chose for the second blog was ” Updated NASA Data: Global Warming Not Causing Any Polar Ice Retreat”. In 1979 NASA put up a satellite that would be used to measure the ice caps. In 2012, they reviewed the data from the satellites and learned that the total polar ice extent has remained above the 1979 average. These findings can conclude that global warming in not causing the ice caps to melt. There was a period of time in 2005 that the ice caps were melting and receding at approximately 10 % of the 1979 measurements. The last update to the data was in may 2015, and that data showed that the ice caps were 5 % greater than the 1979 average.

What does this all mean? It means that originally we thought that global warming was melting the ice caps and raising sea temperatures. In reality, the ice caps melt and then grow at their own rate. There was a large amount of ice in 1979, and then in 2005 they drastically started to melt but it leveled out again by 2012. Now in 2015 we have more ice caps then ever before.
