Extracts from this document...


´╗┐Outline how global warming may impact on human activity through increasing the level of extreme weather. Global warming is believed by many scientists to increase the frequency and the intensity of many types of extreme weather. Extreme weather is weather which is unusually severe (e.g. when hot weather turns into a heat wave) or that occurs in an area where it?s unexpected (e.g. drought in a commonly wet area). Higher temperatures due to global warming cause changes in global air circulation and ocean currents. This means that some areas will experience less rainfall than usual and others will receive more. Areas experiencing less rainfall may have more frequent and more severe droughts. South-Eastern Australia has been suffering through a long-term drought since 2002. ...read more.


However Australia is a MEDC therefore it?s more able to cope with the impacts of the drought. Hurricanes are another increasing event due to global warming which impact heavily on human activity. Hurricanes can only form when the sea surface temperature is warmer than 26.5 degrees centigrade. Global warming increases ocean temperatures, making the conditions for a hurricane to form more frequent. Increased temperatures also increases the energy supply for hurricanes making them more severe. In August 2005, Hurricane Katrina hit the USA- a category 5 hurricane. It severely affected people?s livelihood especially in Louisiana where over 70,000 businesses were affected and 230,000 jobs were lost. Coupled with this was the destruction of the Rigolets Bridge in New Orleans and the Biloxi Bay Bridge on the US Route 90 highway, which heavily hindered people?s access to work, affecting the income of even more Americans. ...read more.


However Carlisle is a MEDC and has flood defences which protected 6000 properties. Although, despite this people lost their jobs as 350 businesses had to shut down as there was no electricity or telephone service e.g. United Biscuits, the largest employer in Carlisle, was flooded with 3m of water and 33 out of 1100 employees lost their jobs. The flooding also caused the failure of mobile networks and landlines which meant people were unable to call for assistance which particularly affected the ill and elderly. Overall global warming severely affects human activity through its connection with extreme weather. The different types of extreme weather greatly impact on economic, social and environmental aspects of people?s lives; however significantly less in a MEDC than a LEDC. ...read more.

Another aspect in which humans can create plagio-climax communities is through farming. One aspect of farming is pesticides which influence ecosystems.

    Aspect - the direction in which a sloped location faces - can also affect its temperature, because the slope facing towards the Sun has no shade or shelter from the Sun's direct heat, and so is heated not by the air, but by direct contact with the Sun's heat rays.

    However, man has tried to limit the challenge by building structures on engineered stilts, or a bed of gravel up to 1m thick for roads. Frost heave can lift piles and structures out of the ground; hence piles for carrying pipelines are embedded deep in the permafrost to overcome mass movements in the active layer.
