...Global warming is largely attributed to human activities that emit greenhouse gases to the atmosphere rather than the natural causes. The greenhouse gases such as carbon dioxide are the main causes of global warming since presence in the atmosphere leads to absorption of heat energy from the sun rather than emitting it to the space (Silver 135). The issue of climate change is a global concern since affects all regions and not just the countries where there are huge emission of greenhouse gases. Despite this, the initiatives to control global warming mainly lie with the governments, environmental organizations, and industries whereas there is little input of the individuals. These agencies are characterized with deep information about the consequences of global warming that is linked to strong intervention practices adopted. There are numerous researches conducted on global warming and consequences whose discussions are embraced in government and environmental agencies. Greater success of intervention practices would be achieved through increased involvement of the people. Since the knowledge of global warming impacts is influential to the development of control measures, greater understanding of the impacts of global warming would be instrumental to attain increased involvement of individuals in intervention practices. Global warming causes extreme temperatures, which affect quality of life and could be unbearable to people and other living organisms in highly affected regions...

...The Impacts of Climate Change on the continent of Africa The African continent makes the least contribution to global warming, yet it is the most vulnerable to climate change- explain why? Africa is the continent that makes the least contribution to global warming, but yet it is the most vulnerable to climate change. This may be because the population is dependent on resources which are climate-sensitive such as local water for farming and drinking. Africa is the poorest continent in the world which means it has very limited resources to respond to changing climate. Apart from poverty is suffers more than any other region from corrupt governance, civil war and constant tribal conflicts. The political turmoil means the appropriate responses aren’t made, making the impacts of climate change worse. The country also heavily relies on agriculture (70% of all employment), which is highly sensitive to climate change. Only 4% African farmland is irrigated, making agriculture susceptible to drought. These people have a reduced capacity to cope, e.g. subsistence farmers, who only grow enough to meet the needs of their family and have no income, will be at risk of starvation it climate change affects their crops. Future prediction Areas that are already dry (arid and semi-arid environments) are getting drier. Wetter areas (tropical and sub-tropical environments) are getting wetter. The whole continent is getting warmer – around 0.5 *C warmer in the last century...

...Global Worming Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation. The global average air temperature near the Earth's surface raised 0.74 ± 0.18°C during the last 100 years. The delay in reaching equilibrium is a result of the large heat capacity of the oceans. Increasing global temperatures will cause sea level to rise, and is expected to increase the intensity of extreme weather events and to change the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yields, trade routes, glacier retreat, species extinctions and increases in the ranges of disease vectors. Remaining scientific uncertainties include the amount of warming expected in the future, and how warming and related changes will vary from region to region around the globe. There is ongoing political and public debate worldwide regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to its expected consequences. Most national governments have signed and ratified the Kyoto Protocol, aimed at reducing greenhouse gas emissions. The term "global warming" is a specific example of the broader term climate change, which can also refer to global cooling. In common usage, the term refers to recent warming and implies a human influence. The detailed causes of the recent warming remain an active field of research, but the scientific...

... January 22, 2013. Global warming is a threat to mankind and its existence; although we are yet to see or feel the effects. However, understanding the cause, and implementing measures to save the planet are of dire urgency otherwise, the impact will be imminent in the near future. In approximately 1,000 years ahead due to rapid growth in the world’s population, and Man’s ever-growing chemical technologies, the impact of global warming is predictable. Global warming can be defined as the gradual increase of the earth’s atmospheric temperature due to the release of carbon dioxide, methane gas, fossil fuels, and other toxic chemical emissions trapped in atmosphere that causes correspondence changes in climate. These changes are rapid in the global atmosphere over a relatively short period of time, and becoming more prevalent in the world presently. There are numerous records that show that our world as a whole is getting incredibly warmer, poor health conditions, strangulated economy, and environmental degradation. Some say the world will end in water due to melting ice, some say it will end in fire as a result of radiation. From my observation and understanding, I hold with those who favor fire. Global warming affects human health, the world economy, our environment, and the planet as a whole. Health is the general...

...Global warming is a very sensitive topic and one of the biggest troubles facing the world nowadays. Global warming refers to the increase in the average temperatures of the air and sea at Earth’s surface and the climate change. Over decades, scientists and researchers have made plenty of researches and decided that the temperature of the world is rising. However, this increase in temperature is mainly due to human activities on the Earth’s surface. In its recently released Fourth Assessment Report, the Intergovernmental Panel on Climate Change, 1,300 independent scientific experts from different countries around the world are grouped together under the patronage of the United Nations to study the global warming issue and they concluded that there is a more than 90 percent probability that the Earth have been warmed due to various number of human activities over the past 250 years (NASA, n.d.). Global warming should be considered as the greatest threats that affects the existence of mankind on Earth because of several reasons such as the greenhouse effect, tropical deforestation and the melting of icebergs and glaciers. One of the major considerations of global warming is the...

...Global warming blog by Henry Auer Carbon dioxide (CO2) and other greenhouse gases are responsible for global warming experienced since the industrial revolution. Greenhouse gases arise from human use of fossil fuels for power and energy. Major emitters of greenhouse gases include both industrialized countries and, in recent decades, developing countries as well. Higher global temperatures cause the extremes of hot and cold, and wet and dry, weather of recent years. This blog examines global warming and its effects. * Blog Posts * News and Commentary This blog is expressly directed to readers who do not have strong training or backgrounds in science, with the intent of helping them grasp the underpinnings of this important issue. I'm going to present an ongoing series of posts that will develop various aspects of the science of global warming, its causes and possible methods for minimizing its advance and overcoming at least partially its detrimental effects. Each post will begin with a capsule summary. It will then proceed with captioned sections to amplify and justify the statements and conclusions of the summary. I'll present images and tables where helpful to develop a point, since "a picture is worth a thousand words".

...Realities of climate change Name Institution Climate is a measure of the average pattern of variation in temperature, atmospheric pressure, sunshine, wind precipitation, atmospheric particle and other meteorological variables in a given region over a particular long period of time. Climate differs from weather in that weather describes the atmospheric conditions of a certain region at a particular time while climate is the average atmospheric conditions of that region for a long period usually 30 or more years. Hence climate may also be defined as the average weather of a region of a given region over a longer period of time. Climate of a place has components which include; atmosphere, hydrosphere, cryosphere, lithosphere and biosphere. Climate change is the statistical distribution of weather patterns when that change lasts for an extended period of time. Climate change may also be termed as the carbon change because this change is caused by the accumulation of carbon dioxide and other particles that prevent part of the sun’s warming rays from reaching the earth’s atmosphere. The burning of carbon fuels notably wood, oil and coal generates greenhouse gases which creates a layer that trap the heat from the sun close to the earth’s atmosphere. These greenhouse gases cause depletion of the ozone layer that protects the human skin from harmful ultra violet sun rays that may cause cancer. Hospitality and Tourism industry have a two way relationship with the climate. The two way...

...Global Warming is a major problem which our environment faces today terribly. This global warming is caused due to Greenhouse Effect which is a condition in which Earth’s heat trapping increases more from the normal levels. Climate change, devastation of the ecosystem, melting ice over Arctic and Antarctic regions, negative impacts in the agricultural sector are just the problems caused by global warming. Many damages have been caused by this phenomenon. Policies on global warming are made each day. Global average temperature rose significantly during the past century. The prevailing scientific view is that most of the temperature increases since mid-20th century has been caused by increases in atmospheric greenhouse gas concentrations produced by human activity. Most scientists agree that planet’s temperature has risen 0.5 degree Celsius since 1900 and will continue to increase at an increasing rate. As a result, the world is getting warmer. The year 1990 was the hottest year in the last century. There are both positives and negatives to global warming, although the good is heavily outweighed by the bad. Global warming is important for agriculture. It's conceivable that the world's current breadbaskets could become even more productive as temperatures warm, increasing yields. Farmers accustomed to one harvest a year may even see two. What's more, a larger variety of crops could be grown in more locations than is currently possible. As the globe warms, however, high-latitude...

...Global Warming And Its Effects On The Coastal Areas of Bangladesh [pic] [pic][pic] GLOBAL WARMING: Global Warming is the rise in the average temperature of the Earth’s atmosphere, including the surface air and oceans. In simple words global warming is when the Earth heats up. It is caused mainly due to increasing concentration of greenhouse gases in the Earth’s atmosphere. The greenhouse gases, include carbon dioxide, nitrous oxide, methane, water vapor, traps heat and light in the Earth’s atmosphere, which increases the temperature. Today global warming is considered as one of the major environmental issues, which threatens to disrupt the basic balance of the environment and cause large scale destruction. The Greenhouse Effect: [pic] There are certain gases that raise the temperature by trapping the sun’s heat and energy. The Earth’s average temperature would have been about 60Error! Hyperlink reference not valid. colder if it weren’t for these gases. These gases are referred to as “greenhouse effect” because of the way they help to keep the Earth warm. The greenhouse effect makes the Earth suitable for all living things. The Earth might have been freezing or it might also have been burning hot if the greenhouse effect did not occur. However, the presence of too many such gases can cause the Earth to get unusually warmer. The plants would not be able to take such heat and eventually they would have died. The scarcity of plants would cause animals to die...

...water cycle and recycling all causes by human and can influence them. So how human activities can affect our ecosystem? What is the ways that global warming might affect our ecosystems? Is our local ecosystem affected more or less than other parts of the world? Local and surrounding ecologies and environments with specific factors: North Central Texas has a humid subtropical climate with hot summers and winters that are not extremely cold. High elevation areas in the "Upstate" area have less subtropical characteristics than areas on the Atlantic coastline. In the summer, North Central Texas is hot and humid with daytime temperatures averaging near 90 °F (32 °C) across most of the state with overnight lows near70 °F(21 °C). Winter temperatures are much less uniform. Coastal areas of the state have very mild winters with high temperatures averaging near 60 °F (16 °C) and overnight lows near38 °F (3 °C). Further inland in the Houston area, temperatures average between 50 °F (10 °C) during the day and32 °F (0 °C) at night.

...greenhouse gas production during photosynthesis, by taking in carbon dioxide as waste material and producing oxygen, which of course we all need to survive. Scientists predict that the daily addition of greenhouse gases to the atmosphere, combined with daily removal of large portions of the world’s forests, will raise the earth’s average temperature by several degrees in the next century. This in turn will raise the level of the sea and potentially create significant changes in weather patterns on a global scale. As we move into the future, many climatologists expect that most of the United States will warm. What we do not know yet is how to scientifically predict which parts of the nation will become wetter or drier. We do know there is likely to be an overall trend toward increased precipitation and evaporation, and more intense weather systems, in the form of violent rainstorms, blizzards and sun-baked, drier soils. The Facts—What Do We Already Know About Changing Global Conditions (Global Warming)? Global temperatures are rising. Observations collected over the last century suggest that the average land surface temperature has risen 0.45-0.6°C (0.8-1.0°F) in the last century. Precipitation has increased by about 1 percent over the world's continents in the last century, with more rain in high latitudes and less rain in many tropical areas. Sea levels have risen approximately 15-20 cm (6-8 inches) worldwide in the last century, due to melting mountain glaciers and...

...Climate Change Climate change is a long-term alteration in the statistical distribution of weather pattern over periods ranging from decades to millions of years. The world is currently experiencing drastic change in temperature. This change can be felt in the tropical climate areas where the weather is getting hotter and hotter every day. The change in global temperatures and precipitation over time is due to natural variability or to human activity. It is also caused by accumulation of greenhouse effects (Arrhenius, 1896). Should we as humans let this problem worsen? Climate change will affect everything including humans, flora and fauna, and the environment. One of the effects of climate change is how it will affect the people. Climate change will have a huge impact on the people’s health. The health of the people will be affected mostly by air pollution and respiratory problems will have the greatest risk of health effects. Increases in moulds and pollens due to warmer temperatures could also cause respiratory problems such as asthma for some people. Should the effects of climate change get any worse than what it is now, people around the world will have to face some serious problems. Food security will be affected and thus diseases can easily get transmitted. Food or waterborne diseases are acquired through eating or drinking. For example, Hepatitis A is a viral disease that interferes with the functioning of the liver. It can be spread through consumption of food or water...

...consequences of the enhanced greenhouse effect and global climate change Figure [ 1 ] - The greenhouse effect diagram, http://www.ozcoasts.gov.au/indicators/images/oze_fs_009_02.jpg Figure [ 1 ] - The greenhouse effect diagram, http://www.ozcoasts.gov.au/indicators/images/oze_fs_009_02.jpg “The unprecedented increases in greenhouse gas concentrations, together with other human influences on climate over the past century and those anticipated for the future, constitute a real basis for concern” (American Geophysical Union, 2014). The Earth's surface temperature has to be just right for humans, not too cold and not too hot. Thanks to the natural greenhouse effect, which has kept the Earth warm. It’s a phenomenon where the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane that allow incoming sunlight to pass through but absorb heat radiated back from the earth's surface. As there are naturally occurring greenhouse gases in the atmosphere that help keep the Earth warm, added amounts of these gases leads to extra heat being trapped in the Earth’s atmosphere. These gases (carbon dioxide, methane etc.) are being added by human activities and are enhancing the greenhouse effect as shown in figure 1. The global climate change is causing many environmental consequences and will cause more. There are five gases that contribute to the enhanced greenhouse effect. These five gases are water vapour...
