Hello everyone, I hope that you’re fine, today I will write about a news I was reading the last week in a web site called Science Alert, the news talking about “Antarctica’s lost so much ice it’s changed Earth’s gravity”. This is because of the global warming that causing melting of glaciers mainly found in the Antarctic continent that has now lost so much ice it’s caused a noticeable shift in Earth’s gravity, this study was done between 2009 to 2012 for the European Space Agency (ESA) with the satellite GOCE,and was observed that increase in the sea levels due to melting glacier which causes a change in the gravitational field of the Earth is observed (however it is not something to be alarmed in a short term) BUT!! It’s doesn't mean that the lost of the levels don't become something worrying, because this year, an unrelated team concluded that major West Antarctic glaciers have now begun “unstoppable” collapse, and would lead to unpreventable sea level rise of several metres over the next several hundred years. On the other hand the ESA’s CryoSat satellite, which measures the altitude of regions on Earth, also recently revealed that the rate at which ice has been lost from the West Antarctic Ice Sheet has increased by a factor of three every year since 2009.
What else I can say? The results of the global warming are evident and this is a theme that affect to everyone.
