Review of the climate science for severe convective storms, extreme precipitation, hurricanes and typhoons, and severe snowstorms and ice storms in the US shows that the ability to detect and attribute trends varies, depending on the phenomenon. A specific subset of extreme weather and climate types affecting the country is discussed to examine these extreme weather conditions. The categories of storms described were selected as they caused property damage and loss of life. The identification of an extreme occurrence was based on meteorological properties in place of the destructiveness. The primary purpose was to examine the scientific evidence for the prevailing capability to detect trends and understand their causes for certain weather types, including severe convective storms and hurricanes and typhoons.

Teilhard’s cosmological speculation is a valuable basis for an environmental ethics that perceives individual natural objects as good in themselves and the world as good in itself. Teilhard perceives man as fundamentally part of a cosmic environmental whole that is greater than mankind taken individually or collectively. His holistic views on human biological and psychological and social evolution are, I argue,compatible with a biocentric environmental ethics. I discuss some similarities and differences with the views of the deep ecology movement. I show that Teilhard’s hierarchical system is not humanistically oriented in a way that need be interpreted by Teilhardians as contrary to environmental well-being. I argue that Teilhard’s sympathies toward transportation technology, including the automobile, can be interpreted in his holistic manner. I conclude that Teilhard’s theocentric views are also a basis for supporting an environmental ethics which is both optimistic and not anthropocentric.

IT has been affirmed frequently that Aristotle’s Physics contains no concept of inertia. Indeed this character, coupled with his great subsequent influence up to the Renaissance, is often considered a key reason for the charge that Aristotle produced a set-back of one thousand years in the development of physics. Our purpose here is to attempt to put in a balanced perspective the Aristotelian doctrine and ancient anticipations of the concept of inertia; no attempt is made to study the medieval period. A classic passage cited to illustrate the position of Aristotle is the analysis of projectile motion in Book VIII of the Physics.
