Attention has begun to shift from local, short-term seasonal patterns of temperature, rainfall, other elements of the weather, toward longer-term trends that can affect the entire Earth, se long-term (typically 30-year) weather trends are called 'climate.' It is therefore important understand the difference, as well as the relation, between 'weather' and 'climate.' An example of the relationship between weather and climate is El Nino, which is weather with local, short-term consequences as well as with global, long-term importance. In the ort-term. El Nino can bring a dry summer for some regions and a wet winter for others; however, over the course of many years, the number of times El Nino conditions occur may decade changes in the global climate. Variations in the behaviour of the weather over long time periods, such as from one century another, are referred to as climate change. While the third study, released in 2005, found declining levels of some chemicals (blood lead levels in children), exposure to many contaminants persists, and first-time exposure of others (such as widely used synthetic insecticides) has increased.

The physical environment of school buildings and school grounds is a key factor in the overall health and safety of students, staff, and visitors. School buildings and grounds must be designed and maintained to be free of health and safety hazards, and to promote learning. Climate change 2000 words, TOPIC: Choose one organisation that has made a significant contribution to debate on the issue of climate change and critically assess the connection between its values and interests, its advocacy positions and its use of science.

Climate itself adjusts from the times of 'ice ages,' hen huge ice sheets covered large areas that are currently ice-free, to periods similar to today hen ice sheets are largely confined to Antarctica, Greenland, and the floating Arctic sea ice. Paleo-climate records indicate that much of the climate changes over the last two million years occured in a rather cyclical manner; with glacial periods lasting roughly 100,000 years with warmer interglacial periods of 10,000 years occurring in between. The sun, of course, is the ultimate source of heat energy reaching the Earth, fueling our weather systems, and establishing our major climate zones. There is, however, good evidence that larger variations in the sun's activity do occur. For example, during the last half of the 17th century, there was a period of greatly reduced solar activity. This was also a time of harsh winters and extended bitter cold referred to as the Little Ice Age. ![]() Scientists do not yet understand the underlying cause of such larger scale variations in solar activity, but do know that they can play a key role in shaping the Earth's climate. Global climate has been changing and still continue to change. Over a long period of time, climatic fluctuations may be such that, a shift in type of climate prevailing over a given area, takes place. In that case, we talk of a change in climate or climatic change. Various terms used to describe variations in climate, namely, climate variability. Climatic fluctuations, climatic trends, climatic cycles and climatic change, refer to some appropriate time scales and can only be validly used within such time scales. The evidence of past climatic change is many and varied, such biological, lithogenic and morphological. School Essay On Why Are Elevators NeededPrior to the 1990s, scientists largely believed that the shifts in climate between ice ages and warmer periods occurred over centuries and millennia due to the large amount of time necessary to build up or melt an ice sheet over a kilometer in thickness. Geologic evidence from the last decades, however, shows that there have also been rather abrupt periods of climate change spanning anywhere from years to decades. Abrupt climate changes can occur when variable that change gradually push the Earth's system across some limit of instability. High School Essay On Global WarmingOne of the known examples of this rapid change is the Younger Drays, which was a sudden interruption gradual global warming that began 12,800 years ago after the end of the last glaciations. The sudden return to a cold global climate lasted for 1,200 years and was followed by a very rapid warming of about 8°C over the course of 10 years. Argumentative Essay On Climate Change![]() Climate' variation occurs as a response to 'climate forcing,' which are factors that cause either a warming or cooling of the atmosphere. Over most of the Earth's history forcing have been entirely natural, caused by continental drift, variability in solar radiation, chain in the Earth's orbit, and volcanic emissions. However, since the industrial revolution, human activity has had a large impact on the global climate system, increasing the amount of greenhouse gases in the atmosphere, trapping heat and contributing to global warming. The Intergovernmental Panel on Climate Change (IPCC) reported that the Earth's average surface temperature during the 20th century increased approximately 0.6°C. While this may seem like a small change, global temperatures are generally quite stable.
