Trump White House quietly cancels NASA research verifying greenhouse gas cuts

You can't manage what you don't measure. The adage is especially
relevant for climate-warming greenhouse gases, which are crucial to
manage—and challenging to measure. In recent years, though, satellite
and aircraft instruments have begun monitoring carbon dioxide and
methane remotely, and NASA's Carbon Monitoring System (CMS), a
$10-million-a-year research line, has helped stitch together
observations of sources and sinks into high-resolution models of the
planet's flows of carbon. Now, President Donald Trump's administration
has quietly killed the CMS, Science has learned.
