An increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, probably including expansion of subtropical deserts. Warming is expected to be Strongest in the Arctic and would be associated with continuing retreat of glaciers, permafrost and sea ice. Other likely effects include changes in the frequency and intensity of extreme weather events, species extinctions, and changes in agricultural yields. The atmospheric concentrations of several greenhouse gases are rising as a result of human activities on earth.

Carbon Dioxide, one of the cost important industrial gases today, is released in the atmosphere largely by burning of fossil fuels like coal, natural gas and oil. Its concentration in the atmosphere is known have increased by 30% over the past centuries. Like CO other greenhouse gases such as methane, nitrous oxide have been increasing as well. Its impacts can be broken down into the following: Human Health Human health will be severely at risk if global warming continues to grow.

Heat related illnesses and deaths could increase because of hotter weather and longer heat waves. Rising temperatures could also significantly reduce air quality. This would create ideal conditions for the increase in frequency and severity of several respiratory ailments. Agriculture Agriculture depends very heavily on a stable climate. Crops are very precise about the soil, moisture, temperature, carbon dioxide and other materials they require. With global warming occurring, the patterns of agricultural production are certainly going to change.

Global Warming will also lead to more intense weather conditions like heavy rains and floods resulting in more ND more crop destruction. These changing rainfall patterns could also shift crop diseases and pests and create water shortages in some areas. Extreme Weather Changes *more hurricanes, floods and droughts *longer spells of intense heat or rain on different regions of earth *rising sea levels as the polar caps will melt. Sea level is already on an all time high since its recording began. Natural Habitats In the past the environment has always adopted the ongoing climatic changes on the planet.

But whenever sudden changes have taken place the effects have been devastating, and same is the case with global warming. The fact that earth’s overall temperature for every region is going to rise considerably, it is very likely that the forest and plant population of the area will become extinct and in some places totally finish. Forest fires are likely to become more frequent and severe if the soil becomes dry. Depletion of Ozone Layer Scientists believe that rising Global Warming will result in a weaker ozone layer. The Ozone layer protects all life on earth from the harmful Ultraviolet radiations coming from the Sun.
