Global Warming - Research Paper Example In a general manner, global warming can be defined as a rise in the temperature all around the globe. But global warming is not limited to only the rise in temperature but it is also associated with bringing about other environmental changes. These changes have a very major effect on the atmosphere of the world. Global warming is hence a very important issue that is increasing and affecting the global environment. It results due to many reasons and harmful human activities serve as the major cause of global warming. Global warming poses a great risk for life on this planet and hence this issue needs to be dealt with in the best possible manner (Houghton 2004). With the passage of time, it has been realized that global warming is an international problem and it has led to many demographic as well as temperature changes in the world. The National Climatic Data carried out a study which presented with very alarming as well as essential findings with regard to global warming. The study p resented the fact that the temperature which was recorded in the year 2004 in the United States of America was the 4th warmest temperature on its record since the year 1880 (NCDC 2004). Causes The study of the climate of the Earth along with the global climatic changes and patterns have served to be of great assistance in analyzing the reasons which have led to the problem of global warming. Many causes have been linked to this global issue with human activities being counted as the major reason but it is also believed by a group of researchers that global warming is not associated with human activities but it is rather a natural phenomenon. Carbon emissions can be specified as the major cause of global warming. The factories which are using the fossil fuels during their manufacturing processes are giving out a great amount of carbon and this leads to a great change in the temperature of this world. The trees planted in the world are considered to be of immense importance in stoppin g the problem of global warming to expand. A tree intakes carbon dioxide during its respiratory process and this helps it to reduce carbon dioxide from the environment. However after a tree dies or the wood in it decomposes, carbon dioxide is given off in the environment. This has been seen as a major cause of the alarming high rates of carbon dioxide in the air these days. In the present years many forests have been burnt by the people or have been burnt naturally due to some accident. These factors have caused the trees to die and release carbon dioxide in the air. In the recent years fires have erupted in the major forests of this world. The fires which erupted in Amazon during the years of 2000 and 2005 can be viewed as a major setback for the environment of this world. It destroyed an area of 132000 square kilometers of the Amazon forest. This area is estimated to be the size of the whole country of Greece. These fires resulted in the release of a huge amount of CO2 into the at mosphere. And it is estimated that the amount of CO2 released during these fires is in billions (Chemical & Engineering News, 2005). Deforestation, climate changes and forest fires have been the major causes of the release of CO2 in the

A Race for Intelligence Gains through Aerial Reconnaissance Term Paper

A Race for Intelligence Gains through Aerial Reconnaissance - Term Paper Example One of the most striking features of the Mosquito bombers as reconnaissance vessels was its reliable speed in aerial space. Technical features range to incredible numbers such as with the Mosquito PR Mk 34 and PR Mk 34A. These units had addition fuel carried in a bulged bomb-bay - 1,192 gallons which was the equivalent of 5,419 miles. A further two 200 gallon drop tanks under the outer wings gave a range of 3,600 miles cruising at 300 mph. Powered by two 1,690 hp Merlin 114s first used in earlier Mosquito units. A total of 181 were built, including 50 built by the Percival Aircraft Company (Bowman 165).As what had been explained above, both Spitfire fighters and the Mosquito bombers were the most versatile aerial vessels of the British Royal Air Force. Both were proven exceptional when it came to dogfights and bomb raids respectfully. They were efficient in aerial defenses that kept enemy aerial raids at bay. Both units were also useful in assault missions where escort Spitfires prov ided cover for raiding Mosquito bombers above enemy territory. More importantly, espionage missions were the key factors which created the Spitfire and the Mosquito a treasure to the British Royal Air Force. The speed and efficiency both the mentioned fighter and bomber units possessed were the primary aspects which catapulted the Spitfire and the Mosquito into heavy reconnaissance tasks. Flexibility to adopt with the environment and the maneuverability of the mentioned units were beneficial for low, medium and high altitude spying.  Ã‚  ...

On the opposite end of the spectrum, the Luftwaffe provided the Germans with unique espionage units. At the onset of the war, ordinary German passenger planes were used as the primary aerial vessels for the campaign of enemy espionage. These were indeed decisive actions taken by the German intelligence because they risked innocent civilian
