Colorado River Has Lost 1.5 Billion Tons of Water to the Climate Crisis, 'Severe Water Shortages' May Follow
Millions of people rely on the Colorado River, but the climate crisis is causing the river to dry up, putting many at risk of "severe water shortages," according to new research, as The Guardian reported.
Longer periods of drought and rising temperatures have decreased the river's annual flow by 20 percent compared to the last century. The researchers, who published their study in Science, say that global heating has caused mountain snowpacks that feed the river to disappear, which leads to increased evaporation, as The Washington Post reported.
"That's the thing I found most fascinating about this study," lead author Chris Milly of the U.S. Geological Survey said to KNAU. "As the snow cover dwindles due to warming, it's reflecting less sunlight back to the atmosphere. So the basin's absorbing more sunlight. That sunlight is powering evaporation out of the basin. Now when that evaporation—the water is taken out of the basin due to the evaporation, there's less water flowing down the river to the 40 million people that are waiting for it."
Snow and ice reflect sunlight back away from the Earth's surface, a phenomenon known as the albedo effect. The loss of snow and ice means the Earth absorbs more heat.
Milly and his research partner, Krista A. Dunne, found that for every degree Celsius of warming, the river's flow decreases 9.3 percent. Recent studies have confirmed that the river's steady decreased flow since 2000 is due to rising temperatures. The decline has amounted to 1.5 billion tons of missing water, equal to the annual water consumption of 10 million Americans, as The Washington Post reported.
About 40 million people live along the Colorado and it supports nearly $1 trillion in economic activity each year and provides 16 million jobs. Its waters cover a wide expanse, according to The Washington Post. Its waters are channeled as far away as California's Imperial Valley and central Arizona, where its used to irrigate crops, as well as across the Rockies to supply drinking water for Colorado's biggest cities. The Colorado feeds the two largest water reserves in the U.S., Lake Powell and Lake Mead. Lake Mead supplies Las Vegas with almost all of its water, as The Guardian reported. The huge reservoir formed by the Hoover Dam has dropped to levels not seen since the 1960s.
So far the world has heated up by about 1 degree Celsius over pre-industrial times, but it is on course to rise 3 degrees Celsius by the end of the century unless emissions are drastically cut, as The Guardian reported. For the Colorado River this means, an "increasing risk of severe water shortages," the study says. Increased rainfall will not offset the loss in reflective snow.
"This has important implications for water users and managers alike," Brad Udall, a senior scientist at Colorado State University and an expert on water supplies in the west who was not involved in the research said, as The Guardian reported. "More broadly, these results tell us that we need to reduce greenhouse gas emissions as soon as we possible can. We've wasted nearly 30 years bickering over the science. The science is crystal clear – we must reduce greenhouse gas emissions immediately."
Andrew Mueller, general manager for the Colorado River District, who was not involved in the study, wrote in an email to The Washington Post that the new findings provide "confirmation of significantly grim indicators about future flow in the Colorado River."
He added that the amount of water that would disappear with another 1 degree C temperature rise is nearly five times what Las Vegas uses each year. "A decline in flows of this magnitude will present a significant challenge to all inhabitants in the Colorado River Basin."

The coronavirus has resulted in stress, anxiety and fear – symptoms that might motivate a person to see a therapist. Because of social distancing, however, in-person sessions are less possible. For many, this has raised the prospect of online therapy. For clients in need of warmth and reassurance, could this work? Studies and my experience suggests it does.
Telehealth Versus Traditional Therapy<p><a href="https://www.cigna.com/hcpemails/telehealth/telehealth-flyer.pdf" target="_blank">Private insurance companies</a> like Cigna and Aetna, have come around; they now provide coverage for what they see as a "legitimate" service. And <a href="https://www.prnewswire.com/news-releases/american-wells-2019-consumer-survey-finds-majority-of-consumers-open-to-telehealth-adoption-continues-to-grow-300906438.html" target="_blank">surveys show</a> consumers are receptive to telehealth counseling: no driving to an appointment, no searching for a parking space, no worries about childcare while they're away, no need to switch providers if they move, and no problem if the specialist happens to be far away.</p><p>Online therapy opens doors for clients who wouldn't otherwise seek help, <a href="https://www.worldcat.org/title/empirical-examination-of-the-influence-of-personality-gender-role-conflict-and-self-stigma-on-attitudes-and-intentions-to-seek-online-counseling-in-college-students/oclc/941976505" target="_blank">particularly patients</a> who feel stigmatized by therapy or intimidated by a stranger sitting across the room from them. Often, <a href="https://doi.org/10.1089/1094931041291295" target="_blank">people open up</a> more easily in telehealth sessions. Firsthand accounts have detailed <a href="https://www.romper.com/p/i-tried-online-therapy-for-a-month-this-is-what-happened-13630" target="_blank">positive experiences from consumers</a>.</p>
Overcoming Prejudices About Online Counseling<p>Now COVID-19 is forcing most traditional psychotherapists to adapt their practice to <a href="https://www.psychologytoday.com/intl/blog/expressive-trauma-integration/202003/covid-19-etherapy-in-times-isolation" target="_blank">online counseling</a>. After experiencing the medium, they are <a href="https://www.wecounsel.com/blog/why-every-therapist-in-private-practice-needs-a-telehealth-option/" target="_blank">overcoming their prejudices</a>. Many will convert some or all of their caseloads to telehealth after the pandemic ends. Most of our clients seem to be good with it: responding to a satisfaction survey, 85% of USF students strongly or somewhat agreed their telehealth experience was comparable to an in-person visit.</p><p>All this allows a continuity of care for clients that before was impossible; there is, however, a caveat. Because of the coronavirus, some of my clients at USF who live out-of-state have moved back home. That means, legally, I can no longer serve them. Even though they are still USF students, my license is valid only in Florida.</p><p>For telehealth to work effectively, our national system of licensing and regulation law needs to adapt. Although the federal government temporarily halted HIPAA regulations to promote telehealth during this time, not all states are allowing out-of-state practice. The coronavirus may not be here forever, but spring break and Christmas holidays always will. We need seamless telehealth across state lines.</p>

Even after the world's largest economies adopted the landmark Paris agreement to tackle the climate crisis in late 2015, governments continued to pour $77 billion a year in public finance into propping up the fossil fuel industry, according to a report released Wednesday.
