NASA has been one of the agencies at the forefront of observing the effects of climate change, and thanks to a collaboration of several space agencies around the world, predicting extreme weather events may be getting more and more accurate. One of the participants in the Atmosphere Observing System mission is the Canadian Space Agency. To discuss the role it will be playing in this project, I got a chance to talk to Thomas Piekutowski, who is head of the AOS mission delivery office at CSA.
