New study shows the ‘fingerprints’ of climate change on 20th century drying

Most New Mexicans understand that climate change is already happening and that its impacts will continue into the future. Now, a new study published in Nature reveals signs of human-caused climate change in the past, too. Relying upon computer models and long-term global observations, the peer-reviewed study shows the “fingerprint” of drought due to warming from greenhouse gas emissions in the early twentieth century. The researchers identified three distinct periods within their climate models: 1981 to present, 1950 to 1975 and 1900 to 1949. In that initial time period, during the first half of the twentieth century, “a signal of greenhouse gas-forced change is robustly detectable,” they write.

Rio Grande roars to life with runoff

This time last year, the riverbed of the Rio Grande south of Socorro was sandy, the edges of its channel strewn with desiccated fish. Even through Albuquerque, the state’s largest river was flowing at just about 400 cubic feet per second, exposing long sandbars and running just inches deep. This year, the Middle Rio Grande is booming, nearly ten times higher than it was last April—and it’s still rising. Running bank-to-bank, the river’s waters are lapping up over low spots along the bank, nourishing trees and grasses, replenishing groundwater and creating much-needed habitat for young fish and other creatures. This year’s high flows through the Middle Rio Grande come thanks to a mix of natural conditions, like snowpack, and also manipulation of the river’s flows from dams, diversions and interstate water-sharing agreements.

There’s a kerfuffle between Facebook, PNM, state regulators and state officials, over who has to pay for about half the cost of a transmission line to the social media giant’s new data center in Los Lunas.The Albuquerque Journal’s Kevin Robinson-Avila covered last week’s unanimous decision by the New Mexico Public Regulation Commission requiring PNM to bill Facebook for half the cost of the new line, estimated to cost tens of millions of dollars. From the story:

PRC members, who voted 5-0 Tuesday to approve the order, contend that PNM cannot bill ratepayers for the transmission project because the line will not benefit retail customers, only Facebook and wholesale electric operators who need the transmission capacity to supply renewable energy to other markets.

As pressure over Gila River diversion grows, NMCAP Entity digs in

SILVER CITY, N.M.—On Monday morning, the organization responsible for planning and building a diversion on the Gila River convened a special meeting to discuss a letter from the U.S. Bureau of Reclamation. In that letter, the federal agency reiterated concerns over the project’s schedule. During the special meeting, New
Mexico Central Arizona Project (CAP) Entity board members placed blame for the
delays squarely on the shoulders of Reclamation itself, along with the
contractor hired to conduct environmental studies, environmental groups and the
administration of former-Gov. Bill Richardson. NM Political Report obtained a copy of the letter, which is from Reclamation’s Phoenix office area manager, Leslie Meyers. In it, Meyers follows up on a March 15 conference call between Reclamation and the CAP Entity and asks if the group plans to continue spending money on the environmental impact statement (EIS).

States set plans for declining Colorado River flows

This week, Congress passed a bill directing the Secretary of the U.S. Department of the Interior to implement an agreement worked out by states that rely on water from the Colorado River. The Colorado River Drought Contingency Plan Authorization Act easily passed both chambers and now awaits a signature from the president. The plan acknowledges that flows of the Colorado River—which supplies drinking water to 40 million people and irrigates 5.5 million acres—are declining. And it represents efforts by the states, cities, water districts, tribes and farmers to make changes that will keep two important reservoirs from dropping too low. Had they not come to an agreement, the U.S. Bureau of Reclamation would have imposed restrictions on water use.

Tests: PFAS limits below federal limits in drinking water near Cannon

According to recent tests, Cannon Air Force Base’s public water system is safe. In response to the discovery of groundwater contamination last year, the state of New Mexico conducted follow-up testing this spring. Samples from two of the four wells currently supplying drinking water tested by the New Mexico Environment Department (NMED) did contain polyfluoroalkyl substances, or PFAS. That includes samples from the Turquoise Estates drinking water system. But the levels are below the federal health advisory.

Tracking the methane boom

On a late March weekend, State Land Commissioner Stephanie Garcia Richard headed out to the Permian Basin, to visit oil wells on state trust lands. These are wells that churn out profits for corporations, build up the state’s general fund from taxes and royalties and send money to schools and hospitals. Looking through a special camera that detects emissions of volatile organic compounds, Garcia Richard also saw that the wells are sending methane and other pollutants into the air. “There are seemingly innocuous pieces of equipment, tanks, pipes, and then you look at it with the FLIR camera and you can see these clouds of emissions,” the commissioner said. “We went to some older operations, some newer operations, some [wells operated] by some smaller companies, some by larger companies.”
