11) Jet streams can have abundant influence on ground-level weather by creating low-pressure centers that can lead to storms, and the streams can continue to steer these storms once they are formed
12) Thunderstorms and tornadoes are more likely to occur in the mid-afternoon because they come as the result of heated air that then rises in a column and the rapidly cools; the initial heating is more likely to reach adequate levels for causing a storm during the later afternoon.

5) Oxygen isotopes found in rocks can vary greatly as they are subjected to different temperatures, with hotter temperatures creating "overwriting" of isotopes left by cooler temperatures. The preservation of certain rocks and their oxygen isotopes can yield clues about climate in ancient times.
6) One major problem that climatologists face in using computers to try and model future weather is the lack of adequate and reliable...
The sheer complexity of modeling weather patterns is also largely prohibitive to accurate modeling.
7) the aspects of the Earth's movements that are taken into account in Milankovitch theory are the eccentricity of its orbit, axial tilt, and the precession or reorientation of the rotating axis.
8) Evidence of past carbon dioxide concentrations from ice cores show a strong correlation to temperature changes as measured through a variety of sources, suggesting that the two are very closely linked and that changes in carbon concentration can have major and rapid effects on temperature.
9) Ocean circulation has a huge effect on climate, changing and creating temperature patterns throughout the globe, and transferring heat from certain areas to others, and providing large amounts of water for evaporation and as carbon sinks, reabsorbing many atmospheric gases.
10) the Pleistocene epoch saw several periods of major global cooling, ending with the last ice age approximately ten thousand years ago. Warming also occurred between these ice ages, and all of this had a major effect on individual weather incidents and patterns during the epoch.

Environmental Health Website Review Environmental Health In today's technologically complex society we are all exposed to potentially harmful agents at work, home, school, and in the great outdoors. Tracking the levels of exposure in the United States is the responsibility of the Centers for Disease Control & Prevention (CDC) and the Environmental Protection Agency (EPA), but other non-governmental organizations have been formed in response to this concern and are providing complementary information
..as long as those programs were at least as effective as the federal program." (the Occupational Safety and Health (OSH) Act) The passing of this Act by congress is therefore aimed at ensuring adequate health and safety standards for all workers. In terms of employers, the Act was designed to make sure that the place of employment was free of any hazards that might be injurious or detrimental to safety and
Environmental Case Study (Alberta's Oil Sands) Alberta's Oil Sands represents one of the international environmental problems facing Canada and close to seventy countries across the globe. Albert's Oil Sands proves to be a new course of political conflict within the setting of Canada and at the international level. Oil Sands development is responsible for rapid economic growth of Alberta. This creates ethical or moral dilemma because there is a massive risk
Environmental are vital to the survival of the human beings, animals, and plants in relation to the planet earth. One of the essential environmental issues across the globe drawing critical debate is the aspect of global warming. This relates to the rapid increase in the levels of temperatures thus realizations of the droughts and famine because of climate change. One of the major causes of global warming is human activity.
Also, careless people with guns shot the condors at will; and when ranchers put out poison to kill wolves and grizzly bears the condors then fed on those carcasses and were poisoned as well. In 1937 the U.S. Congress set aside a refuge for the condors in Santa Barbara County and in Ventura County in 1947, trying to protect these great birds, Peeters explains (p. 114). By 1987, there were
