The global climate is changing. It is most likely that it will continue changing throughout the century. It is the greatest challenge today in the 21st century. Climate change puts more stress on the survival of the poor developing countries. There is nowhere does climate change impact more than on the Africa’s fragile ecosystems. The scope and severity of the impacts of the change in the global climate have made the international community to galvanize into action in an attempt to reverse the trend.
Ecosystem is constantly associated with a particular combination of climatic characteristics. (Walter 1968). The patterns of rainfall are changing and temperatures are rising. These, together with other factors are already being felt by both the human and the natural communities. Human are not only the receptors of climate change, but also they drive the process of the change. Humankind, as a driver of global environmental change, has degraded land, caused desertification, deforestation, changed the use of land to suite his purpose, depleted the ozone layer, and caused air pollution among other ways. Majority of these factors have worked synergistically, thereby, compounding the effects on the environment.
The rate and the scale at which ecosystems are being transformed by climate change defy normality. This transformation of the ecosystem by change in the climate makes its inhabitants to respond to the changes differently. As the species interact among themselves and by the
Climate change has affected us in many ways, but it was even more influential on organisms and their community. The Earth is gradually heating and we are left to deal with the consequences. Homes are being destroyed, organisms are dying, and resources are running low. Since 1880, Our Earth’s temperature had increased by about 0.8 degrees Celsius. Climate change is affecting the Earth and scientists say that one more degree will greatly affect people from all over the world. There are many consequences of climate change and each one has a great impact on all of us, but organisms’ homes are being destroyed and thousands of species are dying out. These organisms are imperative to our world and how it functions.
The audience of this book is presumed to be the general person who is not fully intact with the ideas that he or she is disrupting the ecosystem and is not aware of the effects they are doing as a whole. The book argues that no ecosystem is completely inert as things such as climate changes or drought can also affect the enviorment. Without human interaction an environment can still have issues, but the introduction of human life and economy does take a grave toll on the climate. These are irreversible effects that mankind are doing to the ecosystem. The English
Shifts in temperature and precipitation will be a shock to fragile ecosystems which depend on specific climatic conditions. Many species will be unable to adapt as fast as their environment changes and face sharply reduced numbers or extinction. Scientists estimate that a warming of just 2 degree will put as many as 30% of the world's species at risk of extinction. Plants and animals aren’t the only ones feeling the pressure of changing ecosystems. Many regions will face severe water shortages in a warmer world, creating the potential for conflict. It is believed that the genocide in Sudan’s Darfur region is at least in part a response to water shortages resulting from global warming.
Due to the immense anthropogenic release of green house carbon emissions into the atmosphere, there has been and will be major detrimental effects on human resources and the ecosystem. For example, by the middle of the 21stcentury, River runoff will increase by 40% in northern latitudes and also in a few tropical areas, while in dry regions it will decrease by 30%. Some of these tropical areas have already reported and are experiencing water droughts that will only get worse (Gillman 2008). In addition, if temperatures continue to increase to 1.8-5.4 degrees, food productivity and resources will be affected. When the temperatures reach the lower latitudes of what is predicted, there will be a slight increase in food productivity for a little while. However, when the temperatures reach the higher end of the latitudes, food productivity will
Change of the Climate change has become a threat for the communities & Eco systems since the changes occur frequently than it was few decades ago. In past, climate changes were taking place slower allowing more time for Eco systems & communities to get adapted to the changes. As a
Climate change is a rising issue of importance in our day and age, and one that is threatening our global society on many levels. In the past few decades, scientists have discovered that our planet’s climate has been changing at an alarming rate. The way in which we have changed the land to
In conclusion, the human and physical factors are as important as each other in causing change, positively and negatively, in ecosystems. However within these categories there are some factors which are more important than others for example the physical factors which are essential for the growth of plants are more important than those which change rates of growth or the types of species which they cause to grow in different areas. Obviously the most important human factor
The global climate has increased by approximately 0.6°C over the last 100 years (Walther et al. 2002). This increased rate of changes is largely due to humans: the industrial revolution, the advancement of technology and burning of fossil fuels (Timmermann et al. 1999). This human involvement has gradually changed the natural order of the environment and many of its processes. Some of these environmental conditions are not easily predictable, as these climatic changes are also increasing more extreme weather events such as: droughts in the savannah country, floods in low lying areas and an increase in intensity of cyclonic events (Knutson et al. 2010).
Climate change is something that affects our Earth many times in greater ways than we would like to acknowledge. Earth’s temperature has been steadily rising since the beginning of time, but we have seen a huge increase starting in the 20th century, when industrialization began to happen. The issues that arise from climate change are happening more often and at a greater scale. Recently we see the way that climate change affects biodiversity.
In the world today their has been a surge of scientific, political and economical forces hurdling to prove and disprove the existence of global climate change. I assert that the "symptoms" that our planet is suffering are the truest indications to justify worrying about our collective future on this land; which I will present in terms of how the ecology is being effected by global climate change.
The effects of climate change have become more apparent than ever within the last 100 years. Increasing climates have been proven; with the warmest temperatures in 30 years being recorded (Houghton, 1994). Suggested cause of this increase is population change, the ever increasing demand for natural resources to sustain economic growth has resulted in exploitation of ecological systems at a rate never recorded before. These huge changes to the planet will have a knock on effect to individual and global ecosystems resulting in varying levels of positive feedback. Throughout this essay I will be discussing on various ways climate change effects the ecology of the planet.
The problem of climate change is a regular topic of debate. A debate that is rightfully being drilled into the forefront of everyone’s thoughts because the damage has started to become more apparent. The repercussion has started to manifest themselves through altered weather patterns, as the Earth’s temperate zone have become less, for lack of a better word temperate. Unless
Is it too late to go back? Can we leave our plan in sustainable place for future generations? Climate change is happening weather we like it or not, what are we going to do? Mahtma Ghandi once said “ you need to be the change you wish to see in the world”. Climate change is causing unbelievably high levels of carbon dioxide , the global economy is estimated to drop by 23 percent by 2100. Our glaciers are melting at an unbelievable pace, Zacharie Isstrom is melting at a pace of 5 billion tons per year.
Global climate change is real, it has noticeable effects on the environment. Climate change in the earth is caused by numerous activities. When climate change happens; temperatures can rise tremendously. Rapid warming notice nowadays is uncommon in the history of our planet. The rising temperatures will have great effects on the plant’s climate patterns and on all living things. When temperatures increase, different adjustments can occur on earth. For example, it can cause droughts, floods, air pollution, as well as extreme heat waves. Oceans are also experiencing changes: oceans are warming and becoming more acidic, glaciers are melting, and sea levels are rising. As these adjustments will occur in the future, it will cause challenges to our society and environment.
Climate change. A phrase that encompasses a vast wealth of information, the totality of which is difficult to fathom let alone concisely elaborate upon in a condensed format such as a course or writing assignment. Through this course, the interconnectedness with which humans influence the balance of climate change is abundantly clear. Ecosystems plants and animals depend on are all connected and influencing one another but these scales are imbalanced, mostly as a result of human activities. The web of interconnectivity in climate change is complex, but there is a reemerging consensus at it’s core that human actions, such as global development, has major ramifications and the health and welfare of people and the environment are paying the price. Those daring enough to say they aren’t influencing climate change haven’t truly examined the many facets of their lives consuming energy and in turn increasing carbon emissions that alter climate. For most, transportation is a necessity. This usage requires energy consumption, most likely in the form of fossil fuel resource depletion and in turn the generation of carbon emissions. Transportation routes by land or sea may alter ecosystems that further elevate carbon emissions. With an understanding that the topic of climate change and carbon emissions is massive at best, the aim of this assignment will be to provide the reader with a basic understanding of greenhouse gases and carbon emissions and the relation to climate change.
