Answer: How does the author illustrate the idea that humans can save the planet-All the human causes of global environmental change happen through a subset of proximate causes, which directly alter aspects of the environment in ways that have global effects. We begin this chapter by outlining and illustrating an approach to accounting for the major proximate causes of global change, and then proceed to the more difficult issue of explaining them. Three case studies illustrate the various ways human actions can contribute to global change and provide concrete background for the more theoretical discussion that follows.
Explanation:
Forecasters and storm spotters have learned to recognize certain thunderstorm features and structure that make tornado formation more likely. Some of these are visual cues, like the rear-flank downdraft, and others are particular patterns in radar images, like the tornadic vortex signature (TVS).
Storm spotters have been trained to recognize tornado conditions and report what they see to the National Weather Service. Storm spotters can be emergency managers or even local people with a keen interest in severe weather who have taken formal storm spotter training in their community.
