water, rivers

At any time with more than 1,300 satellites in the orbit on the earth, you think we will know everything about this planet, which is to know. Researchers have uncovered a new science study published on Thursday, but the age of exploration has ended. As soon as the Hernando De Soto discovered the Great Mississippi River in 1541, researchers from the University of North Carolina at Chapel Hill and Texas A & M University have charted several new rivers and streams, showing that we have 44 percent more that is what we had ever thought.

In UNC-Chapel Hill, NASA-funded researcher under the leadership of Tamlin Pavelsky, PhD, Global collaborator professor of hydrology, was not for the glory of discovery. Instead, they were trying to figure out how much water is on the ground because rivers and streams combine so many carbon dioxide into the environment, thereby affecting the effects of climate change. It is important to know where carbon goes, they suggest in paper, because if we cannot keep track of it, then we cannot understand how bad our condition really is.

“Our new calculation helps scientists to better assess how much carbon dioxide is growing in the atmosphere every year by rivers and streams,” Pavelsky said in a statement released on Thursday.

Although a greater focus on climate change has focused on gaseous emissions in the burning of fossil fuels, carbon pollution in our rivers and streams (such as fertilizers and human and animal waste) can also leave carbon dioxide in the air. . This ‘outgoing’ team, with rivers and streams, writes about the amount of carbon dioxide in the atmosphere “Fossil fuel is almost fifth of the combined emission from combustion and cement production.

Since the release of decomposed carbon dioxide in the air by rivers and streams is on the surface of water, it is important to know that how much surface area is covered by rotating the water. Therefore, the team turned into images taken by NASA’s Landsat satellite, which they used to make a database called Land Root Widitude, which was more than 30 m wide, with more than 58 million measurements in the rivers, from LandSAT (GRWL).

By feeding GRWL data in a statistical model created by Pavelsky, the team calculates the total surface of the Earth covered by currents and rivers. Overall, they measured approximately 773,000 square kilometers (298,457 square miles), about the same size as Italy or the Philippines. This is a lot of running water – and a lot of space for carbon dioxide exchange – we had ever thought that we had, which is problematic.

The team wrote, “We found that in the global carbon budget, more roles can be played in controlling the flow of land in rivers and streams than in present.” The rising estimates of the surface area of ​​the river are “particularly pronounced” in the Arctic, they note, which are already weak for the effects of climate change. Good news, apart from the fact that we now have 44 percent more rivers than we thought, that we can better track how much carbon dioxide is actually releasing in the atmosphere as a result of human behavior. The bad news is that due to being responsible for all these new rivers, the amount of carbon dioxide actually released is going to reduce.
