Actually it is not. There are many other reports that have been confirmed that say, some water temperatures around the world is rising, even the majority of those that are changing, but there are also some that are decreasing in temperature. Let us not forget that there are also some sensors in the ocean that report that their temperature has still not changed. .Just like how some reports say the glaciers are all shrinking, again not true, some are expanding and growing, the minority.

Some say that melting glaciers and sea ice shows that the water is heating up. The truth is some of the glacier/ice shelfs in Anarctica are actually melting and falling into the ocean because large and small volcanoes have been popping up in their area. These volcanoes were discovered in the water below after the ice shelfs melted and allowed explorers to search the water underneath.

Other reports take the safer and more scientific route. They read reports that come from sensors that float in the ocean dedicated to their own areas. These reports usually report that there are a small majority of water temperatures that are decreasing. In addition to the report that says some water are increasing. There are also a great amount stating that their temperature is staying the same.

But with all of this, there are strong reports that also state that the temperature increase in the ocean is also a natural occurence which comes and goes with tides and earth water cycles. There is no sure report that can counteract those that have been written at this time too many claim and increase, while too many claim the opposite. Many claim a natural cycle while other blame Global Warming. Watch out for the reports you read, there's usually is another reasoning for the report.
