NM Environment Review: Climate change and NM’s future

This week, we shared the entire NM Environment Review online. Next week, we’ll return to sharing only a snippet on the website and saving the rest for subscribers to the weekly email. To ensure you don’t miss out, sign up here. 
Let’s face it: there’s only one story this week. The Intergovernmental Panel on Climate Change released a special report Monday detailing the serious need for action on climate change. As we reported Wednesday, the IPCC noted that if humans don’t drastically reduce greenhouse gas emissions in the next decade, we will not stop warming that’s expected to have widespread and catastrophic impacts upon the Earth’s ecosystems.
National papers, magazines and television programs covered the report, which includes a summary for policymakers.

International climate report warns of drastic, irreversible changes

If humans don’t drastically reduce greenhouse gas emissions in the next decade, we will not stop warming that’s expected to have widespread and catastrophic impacts upon the Earth’s ecosystems.

That’s one of the most pointed findings in a special report from the Intergovernmental Panel on Climate Change (IPCC), which was tasked with studying how a 2.0° Celsius rise in global temperature will affect the planet, its ecosystems and human communities, compared with a 1.5°C temperature increase. According to the IPCC’s special report, if the Earth’s temperature increases by more than 1.5°C, the changes will be “long-lasting” and “irreversible.”

Already, the global temperature—averaged between land and sea temperatures—has risen 1° Celsius, or 1.8° Fahrenheit, since 1880. That change has contributed to sea level rise, the melting of Arctic sea ice, coral bleaching of ocean reefs and ocean acidification. In places like the American Southwest, warming is already affecting snowpack, forest dieoffs, water supplies and wildfire season. “The more warming that we cause, the broader and more intense are the impacts in general,” said University of New Mexico Earth and Planetary Sciences Professor David Gutzler, in summing up the main message of the report.

New Mexico bears the brunt of D.C.’s environment decisions

Given the fire hose of news from Washington, D.C. every day, New Mexicans can be forgiven if they miss stories about environmental overhauls from the White House and funding mishaps in Congress. But ignorance isn’t bliss when it comes to climate-changing methane emissions, less money for public lands and parks or the intergenerational impacts of mercury exposure. At NM Political Report, we’re continuing to track the federal changes that affect New Mexicans. Here are a few of the most important issues that popped up recently.

At the end of last month, Congress let the Land and Water Conservation Fund lapse.

As NM’s water situation worsens, SCOTUS battle over the Rio Grande intensifies

Last winter, snows didn’t come to the mountains, and the headwaters of the Rio Grande suffered from drought. In April, the river—New Mexico’s largest—was already drying south of Socorro. And over the summer, reservoir levels plummeted. Meanwhile, the U.S. Supreme Court battle between Texas, New Mexico and the U.S. government over the waters of the Rio Grande marches onward. At a meeting at the end of August, the special master assigned to the case by the Supreme Court set some new deadlines: The discovery period will close in the summer of 2020 and the case will go to trial no later than that fall.

As warming strains NM’s water supplies, ‘status quo’ no longer works

On the downstream side of Elephant Butte Dam, U.S. Bureau of Reclamation employees navigate a stairwell above the Rio Grande, passing scat from the ring-tailed cats that like to hang out here, and enter through a door into the 300-foot tall concrete dam. Built in the early twentieth century, Elephant Butte Dam holds back water stored for farmers in southern New Mexico, the state of Texas and Mexico. At full capacity, the reservoir is about 40 miles long and can retain more than 2,000,000 acre feet of water. Jesse Higgins, an electrician who manages the powerplant at the dam, goes first and flips on the lights, which flicker and fire up after a few minutes. Labyrinthine tunnels burrow throughout, and water drains along the sides of the narrow, elevated path.

NM’s reservoirs weathered this year. But what will happen next year?

Right now, New Mexico’s largest reservoir is at about three percent capacity, with just 62,573 acre feet of water in storage as of September 20. Elephant Butte Reservoir’s low levels offer a glimpse of the past, as well as insight into the future. Over the past few decades, southwestern states like New Mexico have on average experienced warmer temperatures, earlier springs and less snowpack in the mountains. And it’s a trend that’s predicted to continue. “There was no spring runoff this year.

New study: Colorado River declines due to warming

The Colorado River supplies water to seven states, including New Mexico, before crossing the border into Mexico. Then—theoretically, nowadays—it reaches the Sea of Cortez. Demands from cities and farms, along with climate change, strain the river and affect its flows. Now, a new study shows that even though annual precipitation increased slightly between 1916 and 2014, Colorado River flows declined by 16.5 percent during that same time period. That’s thanks, in large part, to “unprecedented basin-wide warming.” Warming reduces snowpack and increases the amount of water plants demand.

Transparency concerns about oilfield water reuse plans met with silence

As state agencies move forward with plans to study reusing wastewater from oil and gas drilling, some environmental and community groups want the administration to slow down. They’re concerned about the working group’s quick schedule and lack of transparency thus far on an issue they say demands careful study. This summer, New Mexico signed an agreement with the U.S. Environmental Protection Agency and formed a working group to figure out how wastewater might be reused within the oilfield itself—and someday, beyond it. As we reported last month, the state initiated the process with the EPA. Following the publication of that story, representatives from more than 15 environmental and community groups signed onto a letter to the EPA which said the agreement between the federal agency and the state violates the Federal Advisory Committee Act (FACA) and requesting the federal agency withdraw.

NM Environment Review: Western river flows and woes, plus intensifying El Niño and La Niña

Outgoing administration won’t talk about water plan, but gubernatorial candidates will

Anyone who is paying attention to the Rio Grande’s drying riverbed and dropping reservoirs or is worried about declining groundwater levels probably has something to say about how the state might handle current—and coming—challenges. And they currently have their chance. The public comment period for New Mexico’s draft water plan ends next week. And while top state officials wouldn’t speak about the plan, New Mexico’s gubernatorial candidates were eager to share their thoughts about water, drought and water planning in the state. The draft plan released earlier this year by the New Mexico Interstate Stream Commission examines statewide water issues through the lens of 16 regional water plans the ISC developed with input from local governments, nonprofits and stakeholders.
