As this planet heats up, we have to look to space. That won't be done if the man heading NASA denies the science and looks down on the truth of what's happening in our atmosphere. Scientists are in agreement that while climate change might not have caused Harvey, Katrina, Sandy, and other natural disasters, warmer air does hold more moisture and thus has a much greater capacity to make weather events much worse. Harvey, for example, is now being called an unprecedented natural disaster.
