Trump admin scraps NASA program that tracks global greenhouse gases
The Trump administration is quietly bringing an end to NASA's Carbon Monitoring System, which builds high-resolution maps of the world's carbon flow.
NASA’s Carbon Monitoring System (CMS) has for years helped scientists track the global flow of carbon dioxide by piecing together disparate sets of observations into high-resolution models. In addition to furthering our understanding of Earth’s climate, these models illustrate which policies aimed at reducing greenhouse gases are actually effective.
Now, the Trump administration is quietly bringing the $10-million-a-year CMS program to an end.
NASA spokesperson Steve Cole told Science that the program, which will continue until its existing grants run out, was the victim of “budget constraints and higher priorities within the science budget.”
Some experts say scrapping the CMS will put the U.S. at a disadvantage.
“In the long term, dismantling the Carbon Monitoring System will adversely affect our ability to track flows of carbon through our land, oceans, and atmosphere,” climate scientist Rachel Licker told the BBC. “Being able to better track carbon is critical to evaluating efforts and policies aimed at limiting global warming and its impacts.”
The move comes at an inopportune time for climate scientists.
In April, the average concentration of carbon dioxide in the atmosphere reached the highest level the world has seen in 800,000 years, according to the Mauna Loa Observatory in Hawaii. To put the rate of progression in perspective: CO2 concentrations were around 280 parts per million in 1880, while last month they exceeded an average of 410 parts per million—an increase of 46 percent.
Not all of NASA’s climate-related projects are coming to an end, as Steve Cole, a spokesman for the agency, told the BBC:
“The winding down of this specific research program does not curb NASA’s ability or commitment to monitoring carbon and its effects on our changing planet... In fact, Gedi, a new ecosystem carbon-monitoring instrument, is set to launch to the International Space Station this summer.”

The team caught a glimpse of a process that takes 18,000,000,000,000,000,000,000 years.
- In Italy, a team of scientists is using a highly sophisticated detector to hunt for dark matter.
- The team observed an ultra-rare particle interaction that reveals the half-life of a xenon-124 atom to be 18 sextillion years.
- The half-life of a process is how long it takes for half of the radioactive nuclei present in a sample to decay.
What we know about black holes is both fascinating and scary.
- When it comes to black holes, science simultaneously knows so much and so little, which is why they are so fascinating. Focusing on what we do know, this group of astronomers, educators, and physicists share some of the most incredible facts about the powerful and mysterious objects.
- A black hole is so massive that light (and anything else it swallows) can't escape, says Bill Nye. You can't see a black hole, theoretical physicists Michio Kaku and Christophe Galfard explain, because it is too dark. What you can see, however, is the distortion of light around it caused by its extreme gravity.
- Explaining one unsettling concept from astrophysics called spaghettification, astronomer Michelle Thaller says that "If you got close to a black hole there would be tides over your body that small that would rip you apart into basically a strand of spaghetti that would fall down the black hole."
A new study looks at what would happen to human language on a long journey to other star systems.
- A new study proposes that language could change dramatically on long space voyages.
- Spacefaring people might lose the ability to understand the people of Earth.
- This scenario is of particular concern for potential "generation ships".
