Global Warming or Climate Change

New research suggests that sounds, such as whale noises in the low-frequency sound range, by the year 2100 will be able to travel twice as far as they do now because of global warming.

Some 110 million years ago, sound is believed to have traveled up to twice as fast through the seas as it does now. Global warming may be changing ocean sounds, taking them back to the acoustics of more than 100 million years ago when dinosaurs roamed the earth, new research suggests. Rising temperatures increase the acidity of the oceans and allow sounds near the surface to travel further than they currently do, says Rhode Island acoustician David G. Browning. He predicts that sounds, such

This means that the ‘plateau’ or ‘pause’ in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996. Before that, temperatures had been stable or declining for about 40 years.  global temperature changes Research: The new figures mean that the 'pause' in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996.
