Heavier Rainfall Will Increase Water Pollution In the Future (nationalgeographic.com)

An anonymous reader shares a report from National Geographic: If climate change continues to progress, increased precipitation could mean detrimental outcomes for water quality in the United States, a major new study warns. An intensifying water cycle can substantially overload waterways with excess nitrogen runoff -- which could near 20 percent by 2100 -- and increase the likelihood of events that severely impair water quality, according to a new study published by Science. When rainfall washes nitrogen and phosphorus from human activities like agriculture and fossil fuel combustion into rivers and lakes, those waterways are overloaded with nutrients, and a phenomenon called "eutrophication" occurs. This can be dangerous for both people and animals. Toxic algal blooms can develop, as well as harmful low-oxygen dead zones known as hypoxia, which can cause negative impacts on human health, aquatic ecosystems, and the economy. In the new study, researchers predict how climate change might increase eutrophication and threats to water resources by using projections from 21 different climate models, each of which was run for three climate scenarios and two different time periods (near future, 2031-2060, and far-future, 2071-2100).

    Eutrophication actually being reported is being caused by fertilizer runoff, not additional rain. Early predictions of climate change forecast drought everywhere. Now we're worrying about excess rain. Are liberals incapable of reporting good news?

    Good news is politically incorrect.

    I thought "climate change" was supposed to cause worldwide droughts? If you can imagine just any fear you want as being the result of "climate change", then the entire concept becomes meaningless.

    Of course, it's meaningless to begin with. "Change" is what the climate DOES, always has, always will. The entire Gore-ful panic is designed to separate the people from their money and to allow the politicians to fun things forever.

  4. Re:Why wouldn't more water dilute it more? by ChrisMaple · · Score: -1, Troll

    If we were to get less rain, the climate hoaxers would be claiming higher concentrations of pollution due to the same levels of pollutants being run off in lower volumes of water. Furthermore, they've been claiming worldwide desertification due to climate change for many years now. This is just one more attempt to generate panic no matter which way the rainfall trends.

  5. Droughts? it's climate change! Floods, it's climat by ishmaelflood · · Score: 0, Troll

    Ah climate change, the metaphysical mechanism that can be blamed for every possible outcome. Droughts, Floods, higher temperatures, lower temperatures More hurricanes. fewer hurricanes. So long as they can write a panicky headline about it, it'll get published.

    There were several years when the most common predicted effect of carbon warming was drought - endless drought, in every possible place, and there's nothing we can do about it! (Muahahahaha!). Articles like these have been typical:
