It may be a change in the average weather conditions or a change in the distribution of weather events with respect to an average, for example, greater or fewer extreme weather events. Climate change may be limited to a specific region , or may occur across the whole Earth In recent usage, especially in the context of environmental policy , climate change usually refers to changes in modern climate . It may be qualified as anthropogenic climate change, more generally known as global warming or anthropogenic global warming ( AGW Contents Terminology Causes Plate tectonics Solar output ... External links Terminology The most general definition of climate change is a change in the statistical properties of the climate system when considered over periods of decades or longer, regardless of cause.

Climate Change From Wikibooks, the open-content textbooks collection Jump to: navigation search This Wikibook deals with climate change (also referred to as "global warming"). If you care to share your knowledge of this topic, please contribute. Although this book is still in a very preliminary state, we seem to be moving toward a cohesive structure. The book is really two parts: first, a primer on the science of climate change, and second, a study of societal implications of climate change. The first part deals with much more concrete, physically based principles. As such, it can be developed more easily. The second part is potentially more controversial, but not necessarily so; for the early stages of development, the second part should probably be limited to generalities and external links. edit Table of Contents Introduction Science Evidence of Change Causes ... edit Appendices Press Cuttings - the sub-page where we should post press cuttings Further Reading - References and recommendations... non-technical, text, and scientific work to supplement this Wikibook.

4. Climate Change - Simple English Wikipedia, The Free Encyclopedia For current global climate change, see Global warming. Climate change means the variation in the Earth 's global climate or in regional climates over time. http://simple.wikipedia.org/wiki/Climate_change

Climate change From Wikipedia, the free encyclopedia Jump to: navigation search Variations in CO , temperature and dust from the Vostok ice core over the last 400,000 years For current global climate change, see Global warming Climate change means the variation in the Earth 's global climate or in regional climates over time. It describes changes in the state of the atmosphere over time scales ranging from decades to millions of years. These changes can be caused by processes inside the Earth , forces from outside (e.g. variations in sunlight intensity) or, more recently, human activities. Climate change is any significant long-term change in the expected patterns of average weather of a region (or the whole Earth) over a significant period of time. Climate change is about non-normal variations to the climate, and the effects of these variations on other parts of the Earth. Examples include melting of the ice caps at the South Pole and North Pole. These changes may take tens, hundreds or perhaps millions of years. In recent usage, especially in the context of environmental policy, climate change usually refers to changes in modern climate (see global warming). For information on temperature measurements over various periods, and the data sources available, see

In order to avoid dangerous climate change and protect our quality of life, the world’s scientific community advises we cannot let temperatures increase by 2 degrees or more by the end of this century. The effects of climate change are becoming more apparent as north polar ice cap melting exceeds even the worst case scientific predictions. We can take action as individuals can take action to reduce carbon emissions, but the role of Governments as regulators and policy setters is also vitally important.

With such projections, there are many sources of scientific uncertainty, but none are known that could make the impact of climate change inconsequential. Given the uncertainty in climate projections, there can be surprises that may cause more dramatic disruptions than anticipated from the most probable model projections. With climate change, as with ozone depletion, the human footprint on Earth is apparent. The cause of disruptive climate change, unlike ozone depletion, is tied to energy use and runs through modern society. Solutions will necessarily involve all aspects of society. Mitigation strategies and adaptation responses will call for collaborations across science, technology, industry, and government. Members of the AGU, as part of the scientific community, collectively have special responsibilities: to pursue research needed to understand it; to educate the public on the causes, risks, and hazards; and to communicate clearly and objectively with those who can implement policies to shape future climate.

Hurricanes in the Atlantic are likely to become more intense as ocean temperatures rise.
