Earth's Oceans Are Warming Faster Than Anticipated

Earth's Oceans Are Warming Faster Than Anticipated

The new analysis, published in Science, shows that trends in ocean heat content match those predicted by leading climate change models, and that overall ocean warming is accelerating.

The seas are warming much faster than previously feared, warns new research.

For the last 13 years, an ocean observing system called Argo has been used to monitor changes in ocean temperatures, Cheng said, leading to more reliable data that is the basis for the new ocean heat records. Researchers said this showed that, contrary to the claims of some sceptics, the world was warming at a... "The warming of the oceans is a very important indicator of climate change, and we have solid evidence that it is warming faster than we thought", said co-author Zeke house father of the University of California.

Ocean temperatures cited in the paper are recorded using the Argo network comprised of nearly 4,000 robot floats that stay on the surface most of the time but dive to 2,000 meters every few days to measure ocean temperature, pH, salinity, and other details. In reality, the oceans' temperature, at waters down to 2,000 meters, reached a 0.1 degrees Celsius increase between 1975 and 2010.

The earth's oceans have absorbed more than 90% of heat caused by greenhouse gases trapped in the atmosphere, according to the New York Times, making them a vital regulator for the planet's thermostat.

A separate study on Monday, by the European Union's Copernicus Climate Change Service, said 2018 was the fourth warmest year for global surface temperatures in records dating back to the 19th century.

The thermal expansion - water swelling as it warms - would raise sea level 12 inches (30 centimeters), above any sea level rise from melting glaciers and ice sheets.

The world's oceans are warming at an accelerated rate and are much warmer than scientists thought - and things could get a lot worse if nothing is done to stop climate change, according to anew study. The 2013 United Nations. assessment estimated slower rates of heat uptake but did not give a single comparable number. US President Donald Trump, who wants to promote US fossil fuels, plans to pull out of the pact in 2020. It can take more than 1,000 years for deep ocean temperatures to adjust to changes at the surface.

Three of these studies, which were published in 2014, 2015, and 2017, calculated ocean heat content from the 1970s and decades before with the help of an army of floating robots. In addition, the warming of sea water leads to a further destruction of the coral reefs and reduces the oxygen content in the oceans. "And so the first effect will be that sea level will be different in different places depending on the warming".

A warmer ocean also contributes to increases in rainfall and leads to stronger and longer-lasting storms like Hurricanes Florence and Harvey.
