The world is getting warmer each year thanks to climate change
The world is getting warmer every year, thanks to climate change - but where exactly most of that heat here is a surprise. Scientists have announced that 2016 is the hottest record, it is easy to forget that every extra warmth in the air accounts only a small fraction of the heat caused by greenhouse gas emissions in fact and gets more than 90 percent of it in the ocean and now scientists believe that it may Calculates how far the ocean has improved in the past few decades. Kevin Turnberry, a scientist at the National Center for Atmospheric Research, said the new value was far higher than previously estimated. Compared to the IPCC's global warming estimates, new values ??are about 13 percent greater "which really make this paper different from its predecessors," Turnberry said. This is the result of a new methodology for estimating ambient ocean temperatures, A series of steps. In the past decades, there have been many challenges associated with changes in temperature monitoring in the ocean before 2000 or so, and most monitoring tools would have been deployed from ships, this means that scientists only get the most reliable data for parts of the world that fall on Length of main shipping routes. In the last 15 years, Argo network scientists have developed a system of free drift devices designed to adjust buoyancy, so they can sink several thousand meters in the sea, collect measurements, and then rise back up to the surface. There are now about 3500 of these devices deployed throughout the world's oceans, leading to much better dispersion of observations. The new study, which was led by Lijing Cheng of the Chinese Academy of Sciences and included other scientists from that institution, from the National Center for Atmospheric Research, and from the National Oceanic and Atmospheric Administration, uses a new methodology to use both recent Argo measurements and past observations of ships to produce a continuous series of Estimates 1960-2015. The scientists included an updated database of measurements before some of the prejudices in Argo were corrected, as well as information from climatic models, the extension of observations in ocean conditions taken at specific locations on large areas of the sea, and then compared the recent Argo data with measurements that were Created using a new methodology I found that the method produces true results to life. The results indicate that the ocean has been absorbed as much heat as previous research has indicated. In fact, according to Turnberry, the new estimates help explain the observations of sea level rise that scientists have been finding difficult to calculate yet. A certain percentage of sea level rise can be attributed to the expansion of ocean water, caused by rising water temperatures, while the rest comes from the melting of glaciers, scientists have good estimates of how much ice melts in the ocean. The study also suggests that excess heat is not evenly stored throughout the ocean. The Atlantic and southern oceans, in particular, are the largest new heat tanks, and the results indicate, storage is about 59 percent of the heat despite accounting for less than half of the world's oceans. The system is a kind of giant ocean conveyor belt that runs warm water from the equator toward the poles, where it cools, dips into the ocean floor and flows back in the direction The other .. This system helps both heat transfer around the world, which is evident in the process of the coup in both the Atlantic and Southern Ocean waters. While the new findings emphasize the importance of the ocean as a buffer zone for climate change - otherwise, much of that heat remains in the atmosphere or on land - certainly not without consequences. Ocean warming is believed to be one of the main causes of global coral bleaching that has occurred around the world over the past several years, in conjunction with El Niño in 2015. It remains unclear how other living organisms can be affected, but many marine animals thrive better within certain temperature ranges. Many marine biologists believe that continued warming, along with other climate-related changes such as ocean acidification, may force certain species to migrate to cooler or deeper regions in the future. The warming of the ocean surface can also lead to "dead spots" in the ocean - places where layers of warm water stumble over layers of cooler water, Turnberry said. When this class division occurs, it can become more difficult for water to mix and butter as they usually do, a process that helps to stimulate the nutrients and oxygen that are vital to marine organisms.
