This is an alarming news.
Oceans all over the globe are warming much faster than it has been predicted. They are warming 4 times faster! That means bad side effects, caused by water warming, are coming to existence much faster, too.
There are many negative side effects if huge amounts of sea water are warming. This effects could cause devastating effects to local communities, all animals and plants, there. One of the effects it causes is more acidic waters, with its very bad effect to ocean life.
The rise of ocen temperature is caused by many reasons, but two of them, which are particularly strong are tree deforestation and hot/warm water dumped into the rivers or directly into the ocean. While, it is very easy to understand the effect if somebody dumps the hot water into the river, it is not so obvious to recognize the rise in water temperature in areas, were many or all trees were cut and there is no shade to prevent direct sun light reaches the water surface.
Baltic Sea is the area, where the water is warming at the highest speed. The average rise of ocean temperature was 0.3C in 25 years, but in the case of Baltic Sea, there was 1.35C rise.
My Comment: Take even more serious effects of Global Warming and Climate Changes and don’t even think to trust leading politicians, who are mouth full of renewable energy, but they spend billions of Tax payers money in oil, gas, coal, nuclear and terrible pollution of our planet.
