The rate at which greenhouse gases have accumulated in the last half century is alarming. The accumulation has led to the inevitable rise in the temperature values experienced around the globe. Greenhouse gases have directly increased in proportion to the amount of emissions made by equipment and engines using fossil fuels. This effect is also a direct result of the industrial age that came with a shift towards making use of automated diesel driven machines under supervision of a few operators. It is legitimate to put into consideration that there are numerous effects of global warming that may reduce the life occupancy capability of the planet.
The recoded rise in the temperature values around the globe has led to the melting of the major ice zones in the arctic. This has led to the rise in the levels of the water bodies. This melting effect has a double effect when related to the living things occupying these zones. Firstly, the bears and other minority wild lives have sharply reduced in population which leaves these animals exposed to the forces of extinction. The rising of the water levels in large water masses leads to the reduction of the size of land that can be occupied by humans. Another related effect of the increase of water in the large water bodies is the increase in the breeding of mosquitoes and other waterborne disease carriers hence exposing the human and animal population to diseases.
Global warming has also led to the increase in the migration of animals and birds from their natural habitations to occupy other zones of the world that seem favorable to them. For example, researcher Bill Fraser has noted a common feature in the penguins due to their reduction in numbers from about 30000 in Antarctica to about 10000 over a span of only 3 decades. A similar observation is evident in the case of foxes, polar butterflies, plants and other alpine wildlife that have shifted northwards to occupy cooler regions.
Another evident weather effect arising out of global warming is the reduction in the levels of rainfall in most areas that are already prone to drought and high temperatures. The result of this decline in rainfall will be a decline in the availability of fresh water. This will lead to the loss of both animal and plant lives leading to reduced population counts. Going in the same line of weather changes is the increase rate of occurrence of severe weather phenomenon like hurricanes, strong sea tides and waves together with strong desert winds. This will lead to extensive effects on the existing wealth and resources.
It is important to consider that the rate of global warming may turn irreversible in the nearest future . Researchers contrast global warming with air pollution under the grounds that air pollution is easily reversible within a week’s time. Global warming on the other hand is largely irreversible to the tune of a whole decade. It is recommended that recovery measures are put in place to handle global warming before the worst results arise.
In conclusion we note that human activity has been the basis of the extensive rise in the level of global warming. Such activities include industrial actions that directly lead to the increase in the accumulation of greenhouse gases. Some of the noteworthy end-results of global warming include the rise in the levels of the sea due to the melting of the northern hemisphere ice and the sea ice. This leads in the migration of the life existing in these places to other regions.
