Antarctic Ice Loss Big Enough To Cause Measurable Shift In Earth's Gravity
An anonymous reader writes: Contrary to what we were sometimes taught in high school physics, the Earth's gravity is not constant. It actually shows slight variations on different parts of the Earth's surface, and the variations correlate with the density of the material on that surface. The European Space Agency has been measuring gravity for four years, mapping these variations and recording the changes those variations have undergone. Its data indicates "a significant decrease [in gravity] in the region of Antarctica where land ice is melting fastest. Further analysis is, of course, planned so that the whole of Antarctica can be taken into account and "the clearest picture yet of the pace of global warming" can be determined on that continent.
1. Global warming = the world getting hotter
2. Climate change = the changes to the climate due to the increased amount of energy due to warming
3. The land ice is melting, causing it to flow into the sea, where some of it re-freezes. It is expected if warming occurs.
4. Volcanoes release between 65 and 319 million tonnes of CO2 per year. Industry releases ~29 billion tonnes per year. So it takes ~19 hours for industry to release as much CO2 as all the volcanoes do per year.
Maybe people will keep "banging the bell" until people like you actually learn what's happening. You suck as a conscientious individual.
