global climate changes

Global warming has already occurred and will continue to do so. Evaporation will increase as climate warms and there will be an increase in average global precipitation. Local climate conditions are likely to change depending on the modifications o..

Harmful results of Greenhouse Effect is global warming. While the green house gases enable life to exist, problems arise when the atmospheric concentrations of these gases increase. All climate changes up to the industrial revolution occurred naturally as very few gas..

Summary - The basis of life on earth is atmospheric cover on earth and natural cycles like carbon, oxygen, nitrogen and hydrological cycles. Atmosphere is evolved in its present form due to sunlight and rotation of earth on its axis. Many environmental changes like change in rai..

The atmosphere resource of our world is unique and available to our planet only. No other planet is found to have similar atmosphere. Earth's atmosphere is a legacy from history of this planet. It was formed billions of years back. In the formative years, as the earth started cooling, it did ..

Most of the solar radiation entering the earth's atmosphere is reflected back into the space. However some of the heat is absorbed by the gases like the carbon dioxide. This serves to keep the earth warm much like the greenhouses. Greenhouses are glasshouses which maintain a temperature higher tha..

Climatic Factors - Temperature - Temperature is one of the essential and changeable environmental factors. It penetrates into every region of the biosphere and profoundly influences all forms of life by increasing or decreasing some of the vital activities of the organism. It is frequentl..

The dipole pattern of earth's magnetic field is disturbed due to solar winds. Solar winds are a stream of charged particles coming from the sun. These particles ionise the atmosphere above these poles which display a light high up in the atmosphere. This phenomenon occurring in the arctic region is..

The rainfall patterns in the world are governed by differential heating of air layers over different latitudes. Differential heating of air is the main reason for different convectional air current movement from one part of globe to other. The rainfall is associated with these convectional current..

Natural resources that are limited in nature and are liable to be degraded in quantity and quality by human activities are exhaustible natural resources. Examples are forests, soil, wild animals, minerals, fossil fuels etc. The understanding of the environment and its proper conservation, has gain..

>Relative Contribution of Different Greenhouse Gases to Global Warming What aberration is caused in recent 50 - 80 years is, man has added large quantity of green house gases like CO 2 , Methane. This has resulted in changing the global climate. Human activit..
