The first major U.S. study on the impacts of the climate change threat concluded that the country’s water supply is already dangerously polluted.
The National Academy of Sciences report, published Tuesday, found that “there is no evidence of significant impacts to human health, economy, or the environment from climate change.”
The findings are the latest indication that the world is nearing a tipping point that threatens to bring about widespread social upheaval.
The nation is now on track to see a record-low amount of water use, the worst drought since the Great Depression, and widespread outbreaks of extreme weather, such as the recent heat wave.
But the scientists who wrote the report also warned that climate change could wreak havoc on ecosystems that depend on groundwater and surface water, such a wetlands and rivers.
“In some parts of the United States, water quality is already significantly degraded due to climate change,” the report said.
“For example, wetlands and lakes are declining, while river systems and water bodies are severely stressed.”
The study, which used data from more than 40 federal agencies, found significant changes in water quality in the U.C. Davis, California, area, where the study was conducted.
“We’re seeing water quality changes, particularly in areas with large populations of fish and wildlife, which are dependent on surface water for their survival,” said Michael Fauci, the report’s lead author and a research scientist at the University of California, Davis.
Faucom said the study could have implications for water utilities, farmers and businesses across the country.
“If we don’t act now, we will see massive damage to these ecosystems that are important to us, and we’ll be in a really precarious position to be able to feed our people and grow our economy,” Fauco said.
The study also found that some regions are already experiencing water shortages because of the effects of climate change.
“These changes will continue in some places, and some areas will experience shortages because they have been able to adapt,” Fausci said.
While it’s not clear exactly how much water is being wasted in some areas, the researchers said the situation is dire.
“The rate of water loss is greater than the rate of increase in water use,” Fosci said in a statement.
“This could mean that the U,C.
Davis, area is already suffering significant water losses.
This water loss can have serious impacts on local ecosystems, such that water resources and food production are increasingly at risk.”
Faucaio said the results of the study “call for action to reduce water use by 80 percent by 2050.”
But the researchers also cautioned that the problem is not limited to the U.,C.
“It is not just California,” Fafci said, adding that other areas could experience similar changes.
“Other areas in the country are experiencing a similar increase in the amount of wasted water.”
The researchers concluded that while water use will continue to increase in many areas, some parts could see increases in their use.
The researchers said that they believe climate change may have a greater impact on ecosystems in the future because of water shortages, which have the potential to make ecosystems less resilient.
“Climate change is a process that occurs over time, and if the process is not reversed, we may see the loss of some of these ecosystem services that are essential to our human existence, like water, food, and energy,” Faucio said.
Fafio said that while the report was only based on a single region, it should serve as a baseline for the rest of the country and provide a roadmap for the future.
“With the amount that we are already spending on water, it is absolutely essential that we understand where that is going to end up,” Fofic said.
