A new scientific analysis has discovered that climate change implications are more disastrous than once thought.
The vast majority of the extra heat from climate change is stored in the oceans but until recently there were few reliable methods of measuring it. "There is no doubt, none!" the authors wrote in a statement.
Climate change due to human activities "mainly results" from the energy imbalance caused by rising concentrations of heat-trapping gases, Science reported.
Scientists say the warming seas are damaging coral reefs and marine life, and forcing fish to find deeper and colder waters.
We could see many more weather-related problems if the ocean continues to warm at this accelerated pace, especially if there is no human intervention to manage climate change, experts say.
How much plastic is in our oceans?
And if nothing is done to reduce greenhouse gases, "models predict that the temperature of the top 2,000 meters of the world's oceans will rise 0.78 degrees Celsius by the end of the century", it said.
And today, researchers writing in the journal Science claim the warming of oceans worldwide since the 1970s has happened 40 per cent faster than previously estimated.
Prior to Argo, ocean temperature data was sparse at best, relying on devices called expendable bathythermographs that sank to the depths only once, transmitting data until settling into watery graves.
The oxygen content in the world's oceans has decreased since 1960, an average of more than two percent, found a study at the Geomar Helmholtz centre for ocean research in the year 2017. Emissions in the United States jumped 3.4 percent past year from 2017 - the second-largest annual increase in more than two decades, according to a preliminary estimate by the economic research company Rhodium Group. Ocean temperatures around Florence trended 1.5 degrees C (2.7 degrees F) warmer than normal, contributing to about 10% more moisture available in the atmosphere. The 2013 United Nations assessment estimated slower rates of heat uptake but did not give a single comparable number.
This drive, according to the study of the oceans and diving every couple of days to a depth of 2000 meters, to measure data such as temperature and pH-value. The second scenario assumes no change in emissions and projects warming that could severely affect ocean ecosystems and sea levels.
"If the ocean wasn't absorbing as much heat, the surface of the land would heat up much faster than it is right now", Malin Pinsky, an associate professor in the department of ecology, evolution and natural resources at Rutgers University, told The New York Times.
Warmer ocean water also raises sea levels by melting ice, including around the edges of Antarctica and Greenland.
