White House Orders NASA to Destroy Important Satellite
The White House has instructed NASA employees to destroy two major, climate change-focused satellite missions. As NPR reports, Trump officials reached out to the space agency to draw up plans for terminating the two missions, called the Orbiting Carbon Observatories. They've been collecting widely-used data, providing both oil and gas companies and farmers with detailed information about the distribution of carbon dioxide and how it can affect crop health. One is attached to the International Space Station, and the other is collecting data as a stand-alone satellite. The latter would meet its permanent demise after burning up in the atmosphere […]

"You're not far left," a buddy says.
In a world with fascists controlling every part of the federal government, I'm disinclined to argue with "far left" as a description. At least it clearly distinguishes me from the Nazis.

For some reason some people liked that last picture even though it's really not a tiling and shouldn't be tagged for #tilingtuesday , Is there a common tag for #genericfunpicturemadewithmaththatisnotatiling ?
