When people talk about climate change, it can sound political or exaggerated, but at its core, it’s about environmental changes we can measure over time. Scientists like Brad Udall, who studies long-term weather patterns, have found that the Earth’s average temperature has risen slightly over the past century, mostly because of how people consume energy. When coal, gas, or oil is burned, it releases gases that trap more heat in the atmosphere, like a blanket wrapped around the planet. Despite whether someone believes it is man-made or not, climate change forces us to pay attention, and develop methods to protect the land and water that sustain us.
On Monday, September 29th, Udall, an internationally recognized scientist on water and climate change from Colorado State University, visited the Colorado River Indian Reservation to share his latest findings on the Colorado River. He spoke with Tribal leaders about what the future may hold.
Udall is known for his research on the connection between climate change and river systems in the American West. He has spent decades studying how heat, drought, and rainfall affect water levels, especially in the Colorado River Basin. Additionally, Udall co-wrote parts of the U.S. National Climate Assessment, and has testified before the United States Congress about the effects of climate change on western water supplies. His work focuses on researching solutions that balance the needs of people, agriculture, and the environment.
When Udall met with Tribal leadership at the Colorado River Indian Tribes (CRIT) Council Chambers, he was greeted by Chairwoman Amelia Flores, Councilwoman Vanessa Welch, CRIT Attorney General Rebecca Loudbear, CRIT Water Resources Director Dillion Esquerra, CRIT Realty Commercial Manager Herman “TJ” Lafoon Jr., and CRIT Lead Water Attorney John Bezdek.
During his presentation, Udall explained that flows in the Colorado River have dropped about 20% since the year 2000, and that precipitation – the rain and snow that feed the river – is also down about 20%. He said several studies have found that this isn’t just a temporary drought, but a long-term trend he believes is caused largely by human-driven climate change. Temperatures are rising across the Southwest, and according to Udall, “We are now on target for 3 degrees Celsius of warming by the year 2100.” Udall reiterated that his studies show this increase in temperatures is based on an average of estimates, and that temperatures in certain areas, including the desert southwest, could see higher increases.
Udall described the situation as serious and with little optimism. He shared that some scientists are exploring ideas like adding sulfur dioxide to the atmosphere to help cool the planet, though he said most researchers are cautious about such steps because they involve more human interference in nature. “It’s not a perfect solution,” he explained, “but it shows how far people are thinking about how to slow down the warming.” Councilwoman Vanessa Welsh was thankful for Udall’s frankness about the situation stating, “Many of us do know this, but we don’t hear it very often…We intend to protect the river as one of our own.” (more…)
