Lecture :1 Geography: Geography is the study of locational and spatial variation in natural and human phenomena on Earth. Vidal de la Blache Geography is the science of places‚ concerned with the qualities of potentialities of countries. The particuler character of a country is expressed by the totally of its feature‚ the social diversities associated with the diversities of places.Geography mainly divided into two parts. • Physical geography • Human geography Physical

in the atmosphere‚ leading to increased radiative forcing from carbon oxide‚ methane‚ troposphere ozone‚ CFCs and nitrous oxide. The destruction of stratospheric ozone by chlorofluorocarbons is sometimes mentioned in relation to global warming. Although there are a few areas of linkage‚ the relationship between the two is not strong. Reduction of stratospheric ozone has a cooling influence on the entire troposphere‚ but a warming influence on the surface. Thirdly‚ an aerosol is produced by volcanoes

• CFCs have destroyed ozone in the lower stratosphere/upper troposphere causing these zones in the atmosphere to cool 1.37 oC from 1966 to 1998. This time span was selected to eliminate the effect of the natural solar irradiance (cooling-warming) cycle effect on the earth ’s temperature. • The loss of ozone allowed more UV light to pass through the stratosphere at a sufficient rate to warm the lower troposphere plus 8-3/4" of the earth by 0.48 oC (1966 to 1998). • Mass and

While air content and atmospheric pressure vary at different layers‚ air suitable for the survival of terrestrial plants and terrestrial animals currently is only known to be found in Earth’s troposphere and artificial atmospheres. The atmosphere has a mass of about 5×1018 kg‚ three quarters of which is within about 11 km (6.8 mi; 36‚000 ft.) of the surface. The atmosphere becomes thinner and thinner with increasing altitude‚ with no definite

SCIENTISTS FATHOM THE CHARACTERISTICS OF “ATLANTIC JET STREAM”‚ LINK IT TO MISERABLE SUMMERS THAT WERE EXPERIENCED IN UK AND WESTERN EUROPE. “It is a known fact to the people residing in UK and other parts of Western Europe‚ that we experience very unpredictable seasons and weather‚ throughout the year. But‚ what’s circulating in air among people of UK is about the miserable “Wet Summers”; that we have face. It was very depressing to our climate and weather prediction agencies for being incapable

While discussing El Niño‚ Baliunas discusses the computer model’s prediction for the warming of the troposphere by greenhouse gases. Contrasting with the observed warming trend‚ the computer predicts “the air must be warming at a rate of...a quarter of a degree Centigrade per decade” (Baliunas). She uses scientific jargon to explain the warming troposphere‚ and it simultaneously impresses the reader and allows them to trust Baliunas. Next‚ Baliunas discusses the link between
