The Trump Administration has killed NASA’s Carbon Monitoring System (CMS), a program that monitored carbon output worldwide, Science reports.
The move jeopardizes plans to verify the national emission cuts agreed to in the Paris climate accords, says Kelly Sims Gallagher, director of Tufts University’s Center for International Environment and Resource Policy in Medford, Massachusetts. “If you cannot measure emissions reductions, you cannot be confident that countries are adhering to the agreement,” she says. Canceling the CMS “is a grave mistake,” she adds.
The White House has mounted a broad attack on climate science, repeatedly proposing cuts to NASA’s earth science budget, including the CMS, and cancellations of climate missions such as the Orbiting Carbon Observatory 3 (OCO-3). Although Congress fended off the budget and mission cuts, a spending deal signed in March made no mention of the CMS. That allowed the administration’s move to take effect, says Steve Cole, a NASA spokesperson in Washington, D.C. Cole says existing grants will be allowed to finish up, but no new research will be supported.
The agency declined to provide a reason for the cancellation beyond “budget constraints and higher priorities within the science budget.” But the CMS is an obvious target for the Trump administration because of its association with climate treaties and its work to help foreign nations understand their emissions, says Phil Duffy, president of the Woods Hole Research Center in Falmouth, Massachusetts. And, unlike the satellites that provide the data, the research line had no private contractor to lobby for it.
Many of the 65 projects supported by the CMS since 2010 focused on understanding the carbon locked up in forests. For example, the U.S. Forest Service has long operated the premier land-based global assessment of forest carbon, but the labor-intensive inventories of soil and timber did not extend to the remote interior of Alaska. With CMS financing, NASA scientists worked with the Forest Service to develop an aircraft-based laser imager to tally up forest carbon stocks. “They’ve now completed an inventory of forest carbon in Alaska at a fraction of the cost,” says George Hurtt, a carbon cycle researcher at the University of Maryland in College Park, who leads the CMS science team.
The program’s cost is $10 million per year.
