A “rough cut” estimate of water needs in southwestern New Mexico presented to the New Mexico Central Arizona Project Entity, or NMCAP Entity, back in June doesn’t tally up with other water studies for the region. And getting answers from the Interstate Stream Commission about the different estimates has proven impossible.
Tucked away in the southwestern corner of New Mexico, the headwaters of the Gila River pour out of mountains remote and wild. At least five other times in the past century, officials thought about taming or tapping its upper waters—then bumped up against the Gila’s unpredictability or inaccessibility. But the problems of the past haven’t dissuaded New Mexico officials from planning a new diversion of the Gila river. Nor are diversion project proponents deterred by predictions for a warmer, drier future. Some say that makes a diversion all the more necessary.
State and local officials are honing in on the plans for diversion, but plenty of questions still remain, even as the environmental review process is beginning
Silver City officials don’t want anything to do with a planned diversion on the Gila River—or the group of local governmental agencies that have agreed to plan, operate, and maintain the diversion. Instead, the city is focusing on conservation and efficiency.
Recently, the US Environmental Protection Agency released two-page fact sheets about climate change in each of the 50 states. Drawing on sources like the national climate assessments, the fact sheets don’t have new or breaking information. But they do provide a good overview for citizens and decision-makers who might be thinking about the future. In New Mexico, for example:
In the coming decades, our changing climate is likely to decrease the flow of water in the Colorado, Rio Grande, and other rivers; threaten the health of livestock; increase the frequency and intensity of wildfires; and convert some rangelands to desert. The fact sheet also lays out basic information for New Mexicans about declining snowpack, agricultural challenges, wildfire, and impacts to tribal communities.
Climate change won’t just affect rivers and forests. It’ll have widespread impacts on communities and cultures. As parents, teachers, and community members, there’s a lot we can do to make sure all New Mexico’s young people are learning about climate change, the challenges the state is facing, and paths toward possible solutions.
Watershed ecologist Krista Bonafantine wants to reduce political discussions around climate change and just get to the science of the matter. She think it’s possible to do that with students, teachers – and the public – by focusing on changes in the places people live and care about, learning from the past, and using science to make better management decisions.
According to maps published last week by the New York Times, by 2060, temperatures in Albuquerque will exceed 100 degrees on 32 days each year. By 2100, that number more than doubles to 73 days.
As the region warms – and both our surface and groundwater supplies become increasingly constrained – it’s a good time to try and understand the facts. And one another.
