Yeah it is true according to a two reports published couple of months ago. The first study showed that the Earth’s ocean levels rose twice as fast in the past 150 years indicating the impact of human activity on temperatures worldwide. Sea levels are rising 1mm (0.04 inches) every year about 200 years. While the planet is going along its natural procedure, driving cars and other such activities that create carbon dioxide are having a clear impact. Lets just say half is the Earth’s fault and other half is man-made. Mainly this change started some 200 years back. Before that carbon dioxide levels were stable.
Today’s rise is about 200 times faster than any rise recorded. I know i mentioned 200 a lot of times but thats how the information was published. Although the study does not directly address global warming.
