For years, scientists have had their eyes set on the world’s ice shields hoping to monitor changes with the advancements in technological systems. Global temperatures indicated a downward trend in the period from 1940 to 1970, but increased gradually in 1980s. This phenomenon can be attributed to the increase of the amount of sunlight that hits the snow and ice in these regions. As such, various reports have illustrated an accelerated rate of melting raising the sea levels at an alarming state. For instance, a survey done every September to ascertain the area covered by sea ice demonstrates an average decrease at a rate of 8.6% between the years of 1979 and 2007 (Thompson and Kuo, 2012).However, there was a significant loss of sea-ice placed at 24% in the 2007 alone. Various scientists have voiced concerns based on these and current findings that corroborate the eminent danger of melting ice caps and rising sea levels. Extrapolations of existing data suggest that thermal expansion and ice sheet changes will dominate the processes affecting the sea level (Ward, 2003). Similarly, areas that are marginally glaciated are most likely to be ice-free, which will eventually lead to the disappearance of the Polar Regions. ...
This is because these gases increase temperature of the atmosphere near the earth and its troposphere; resulting in corresponding changes in climatic conditions. Fundamentally, the dangers associated with global warming are erratic changes in the weather, which are experienced in extremity, causing persistent natural disasters and extinction of species. In essence, the continual warming trend has been broken down to climatic change, which refers to the measurable effects of global warming. These measurable effects refer to shifts in major aspects of the climate that is, rainfall, temperature, snow, and wind patterns. With this differentiation, global warming is identified as a long-term reference of the effects of these shifts in climatic conditions. Notably also, ocean currents are included as an aspect that facilitates the continual warming trend. Currently, environmental degradation is an issue that requires immediate action because of the escalating rate at which it has been occurring, making it hard for the ecosystem to convalesce. Pollution is considered as the major cause of ozone layer depletion owing to the release of chlorofluorocarbons that rise into the troposphere causing its depletion (Fahey and Hegglin, 2010). Industrial processes and automobiles are responsible for the release and as such, governments have been asked to tax the companies for the emissions. In addition, the destruction of tropical rainforests by logging industries has resulted in destruction of natural habitats of plants and animals, which increases the level of carbon dioxide in the atmosphere. The destruction of habitats interferes with photosynthetic organisms that are responsible for carbon-fixing cycle, which seeks to relieve the greenhouse effect.

Climate Change

...(Intergovernmental Panel on Climate Change, 2008). Reports also cited that the arctic ice shrunk by 2.7% every ten years and with an average of 7.4% decrease every summer season. Areas affected are northern and southern part of America, Europe, Asia, Mediterranean, and Africa regions (Intergovernmental Panel on Climate Change, 2008). Hence, there will be erratic weather and global temperatures. The influence and confluence of sun’s phenomenal flares that emit heat waves, atmospheric natural relations within earth’s axis and the environmental destruction made by human beings, intentional and non-intentional, have contributed or caused...

...?Climate Change Introduction Climate change continues to be a problem not only by several individuals or nations, but rather it is a dilemma for the entire globe. As global warming speeds up, climate change also picks up its pace, a threat from nature to mankind which would yield undesirable effects. Although it is a devastating dilemma, we are not left hopeless. Climate change urges rapid modifications on how we run our systems by altering our individual lifestyles, establishing legislation as the nation’s aid, and participation of other countries in this endeavor. Individuals Human activities are...

The Melting of the Polar Ice Caps

...the water level rise. The melting water from the glaciers drains into the sea and oceans leading to a rise in sea levels. Melting of ice caps and glaciers has negative environmental impacts. It destroys the ecosystems on which flora and fauna depend on. This leads to massive loss of bio diversity in the Polar Regions and the surface water. Decrease salinization of surface water in these regions also occurs (Singer 111). Skeptic scientist are of the idea that the melting of the idea that global warming does not cause melting of the ice caps stating that this in a perfectly natural process. By measuring the annual changes in glacial activity, they have been able to notice...

However, climate change problems are causing destruction of some species of animals. For example, “Polar bears are the world’s largest land predators, and the most majestic creature of the Far North. But dramatic changes, caused by global warming, are taking place in the Arctic that threaten the survival of this spectacular species” (Climate Change and Polar Bears). Atmospheric temperature rise causes melting of ice from the...

The rapid warming and cooling phases have resulted into weather conditions that are so unfavorable for these animal and plants for example the polar bear the depends on the ice seas to survive and the fish species found in these regions that are currently melting and affecting the oceanic balance (Mills 73). Scientist has given a prediction of the future trends in climate and weather patterns attributed to the rapid changes in the climate that are currently witnessed. This will increase the overall sea volumes and create rooms for flooding and strong waves in beaches currently used for tourism and leisure...

Climate change

...Global warming Climate change is the effect brought about by the production and emission of greenhouse gases such as carbon dioxide, methane, and nitrous oxide, into the atmosphere, which causes entrapment of heat, which is fleeing the earth, thus causing overall rise in regular temperatures of the earth (Seymour 15). It is one of the most pressing issues in today’s world as it affects the natural settings and balance of the earth’s ecosystem, which is consequently, affects human beings (Houghton 44). They are various causes of this global warming, natural and man-made with the latter being highly blamed, but how do human actions impact global warming? The human factor is highly credible in causing this...

... Adaptation Response Climate change is a threatening aspect all across the globe. It will continue to change in the coming centuries at unprecedented rates in the recent human history. Therefore, adaptation to climate change is an emerging subject in the modern world (Lo 2012). Adaptation simply refers to the steps put in place to reduce vulnerability and building resilience. This implies that adaptation is the management of the risks posed by climate change with respect to the mitigation decisions revolving around the environment, economy and the future generations (IPCC 2014). This is because vulnerability results from loss of resilience in a system, but resilience is about the level of capability of the people which is limited... they...

...Climate Change Climate change is the most controversial topic in twenty-first century. Approximately all the people across the world have felt the impact of climate change. A study by Karl et al. (99) reveal that the impacts of climate change on a society is deep. The authors explain that effects on the society is felt through basic necessitates such as water, housing, energy, food, transportation, health, and the ecosystem. The effects of fast changing climate have brought serious challenges to the society. The population is vulnerable to catastrophes such as floods or...
