Nitrogen Runoff & Algal Blooms Increasing Due to Global Warming

Changes in Rainfall and Temperatures have Already Impacted Water Quality,
Carnegie Institution for Science, April 24, 2019.

MAIN POINTS

“Changes in temperature and precipitation have already impacted the amount of nitrogen introduced into U.S. waterways...”

“This can lead to toxin-producing algal blooms or low-oxygen dead zones called hypoxia. Over the past several summers, dead zones and algal blooms in lake and coastal regions across the United States have received extensive news coverage.”

Proof in the Past
“...they looked backward to analyze long-term trends in nitrogen runoff going back to the 1980s.”

Direct Impact of Warming
“...warming springtime temperatures and accompanying storms having a direct impact on nitrogen runoff.”

"What we have shown is that deteriorating lake and coastal water quality is not just about how we develop land and how much fertilizer we use on fields; it's also about how human action at a global scale is changing rainfall and temperatures,."

 

Bottom Line

On the Dangers List
It’s time to begin thinking about this year’s potential for blue green water threats as rising temps begin to melt the snowpack. But, this threat, like fire, is further down on our, “dangers list,” from the initial dangers we’ll confront from hiking across steep, snow covered terrain, the rise of raging rivers and dangerous fording conditions, and the chances of powerful late season storms coming through.

We’ll really begin watching for blue green water when the thaw decreases, slows down, and Sierra waters begin to warm under the Summer sun.

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
