Overall, the annual level increase has doubled since 1993. The level of the time has increased the global level level by 4 inches.
“It used to be that we could predict the future based on past trends, but now we know that all these changes are happening,” said Kaushal, a geologist at Maryland, but now all these changes are happening. ” “Nothing is surprising now.”
Kushals mostly study the environment of water shedding outside the sea, such as wet areas, rivers and rivers, which provide about 70 % of human drinking water. However, in a newly published study, he, along with sea experts, saw how salt was affecting seawater from the sea and the earth. Spilller Alert: It doesn’t look good.
Kaushal said that basically, salt is coming from both directions, namely the earth and the sea and meeting in the middle, which represents the problem of “double hassle” for freshwater marine frozen. Salt on the ground is mostly waste water, fertilizer, extraction of resources and road salt.
I did Kushal’s interview for one Newsletter I wrote in January About how road salt is threatening water supply and forest life, and the figures are surprising: According to an estimate, the United States only uses about 25 25 million tonnes of salt every year on the roads. When the snow melts, it can be leaked in salt water sheds. Generally, “weakness is a solution to pollution,” Kushal says, citing the fact that heavy rainfall or dams can reduce the salts by droping fresh water into the ecosystem.
But climate drought and rising temperatures are making this strategy more difficult. During standing periods, low water is available to weaken the system and to shed salt, while the salt is pushed into the water season in the growing oceans, this process is known as interfering with saline water.
“The interaction between human activity and climate change and climate change is very important, Kaushal said. “It increases salt pulses that we see in human activity.”
This problem is especially common in the Delaware River, which is a 330 -mile waterway that runs from New York to the Atlantic in the Delaware Bay. The river provides about 60 % of the drinking water to 1.5 million people in Philadelphia, but interference and pollution in saline water is threatening this important resource.
