Global Warming
Two issues that worry many scientists are global warming and the greenhouse effect. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. What does the greenhouse effect have to do with global warming? When humans release gases into the air, the greenhouse effect will alter the temperature of the earth. More gases in the atmosphere means the earth will start to get warmer, and the result is global warming. On the other hand, if there was no greenhouse effect, the earth would be too cold for humans to comfortably exist.
In order to talk about global warming, we must first learn what causes the greenhouse effect. The three most common greenhouse gases are water

Once that water is in the atmosphere, it’s going to come down somewhere – and, indeed, we have seen the most dramatic flooding ever recorded in recent years. In 2004, 300 million humans, 1 in 20 of us, had to leave their homes for a week, a month, a year, or forever because of rising waters” (The Planet Speaks 124). Much of the gained water would be from melting icecaps in the ocean and melting glaciers on land. Coastal cities and islands could be wiped out.
Global warming would not affect only humans; it would also affect sea life. This would happen because water temperatures would rise. “Corals are intolerant of temperatures just a few degrees warmer than usual” (Fast Facts). There have been problems with corals dying out in the past few years because of increased water temperatures. Other marine life would probably migrate to warmer waters. The warm water would make them think they were in their natural habitat. A downfall to this unknown migration would be that food would become scarce in their new, unadapted habitat. An example is salmon; salmon are also sensitive to the temperature of the water. During the summer when the water is warm, salmon have a high metabolic rate. During the winter months, their metabolism slows down, which is good because less food is available at this time. With global warming and increased water
Climate change is a major global issue. Canada is the ninth largest emitter of greenhouse gas that needs to enact on a climate policy [1] (Mildenberger et al. 2016).Greenhouse gas slows down and prevents heat loss in space which increases the temperature of the Earth’s surface leading to global warming. Activities of energy industries, transportation, residential and commercial activities, manufacturing, construction, industrial processes, and agriculture emit greenhouse gases. Human activities emit Carbon dioxide (CO2) that is responsible for an increase of 85% in global warming (Ayşegül Toptal, Bilgesu Çetinkaya 2017). Loss of sea ice, thawing permafrost, and coastal erosion are already increasing in speed [7-9 Mildenberger et al. 2016],
Rising temperatures are causing melting glaciers, which cause rising oceans. Rising oceans will envelop entire coastal cities, killing or displacing millions of people. Our food sources will dwindle; entire species of animals will become extinct as we destroy their homes to rebuild; and as our population skyrockets, an unimaginable number of humans will be left homeless, starving, and sick.
In the world today, global warming and climate change are one of the main issues with the earth. This issue affects everyone and everything in this world, and even though it seems to be a big problem, most people do not seem to care. The most familiar term is global warming and climate change, but greenhouse gases is one of the main causes and is never mentioned. Greenhouse gases are gases that absorb and emit radiation in the atmosphere, hence makes the earth warmer. The importance of this knowledge of greenhouse gases is so the world will know one of the main causes of global warming and climate change and possibly some
Another huge problem that can be caused by the global warming is an increase in mortality due to health issues. Changing patterns of precipitation and temperature may produce new breeding sites for pests and viruses, shifting the range of infectious diseases. In such way we may probably experience new epidemic strikes of diseases present 100 years ago.
It is largely known that the most significant issue facing the planet today is global warming. There is no doubt it is one of the biggest environmental issues throughout time, though it is widely debated among scientists and environmentalists what the main causes are. Global warming isn’t a new issue, in only 1989 the UK Prime Minister at the time warns that the increasing emissions of carbon dioxide into the atmosphere are going to have a significant impact on the earth in the future (BBC News, 2013). The warming of the earth is caused by greenhouse gases, such as carbon dioxide that trap long-wave radiation in the atmosphere. This warming of the earth surface is referred to as the greenhouse effect. Greenhouse gases are the gases, such as carbon dioxide, methane, and water vapour which accumulate in the atmospheric layers prevent heat being radiated from the earth to escape. Without greenhouse gases the earth would be considerably cooler but with increased human activities, temperatures are rising to an unstable level (Arbogast, 2011).
NGS integrates greenhouse into other major policy initiatives, such as the Natural Heritage Trust, and launches new measures to increase greenhouse emission reduction activities across the Australian community. It provides the strategic framework for an effective greenhouse response and for meeting current and future international commitments. It will provide a fresh impetus for action by governments, stakeholder groups and the broader community and set directions for that action into the next century.
The rise of air temperatures near Earth’s surface over the past century is known as global warming. Earth has experienced periods of gradual warming and cooling throughout its existence due to natural causes, such as volcanic eruptions and variations in the Sun’s output. However, scientists have created the idea of an increase in global temperatures to human cause, mostly the release of greenhouse gases into the atmosphere as a result of industrial industry. These greenhouse gases which absorb and trap heat emitted from Earth’s surface through a phenomenon known as the greenhouse effect.
Climate change affects many things, including the environments, food sources, temperature, and population. If all the ice caps melt, then every coastal city in the world would flood (logos). People will lose their
Second of all, global warming has caused the ozone layer to start to break. The ozone layer is a layer that absorbs the rays of the sun. There is a very big hole in the ozone layer. The breaking of the ozone layer has caused the suns rays to come down at the humans very sharp. The hole in the ozone layer lets the UV enter the atmosphere; it can cause skin cancer, general cancer in addition to many more diseases to humans. There’s a list of things humans can do to help reduce global warming including; plant a tree, carpool, take a shower instead of a bath, use less hot water, use less hot water there is a lot more to this list.
The effects and changes of global warming are many. Changes include rising sea levels due to melting of glaciers and at the Earth’s polar ice caps. Ice is melting worldwide in mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic Sea ice. Therefore the sea level has been rising faster of the last century. As a
First of all, what is global warming? Global warming is the increase of Earth’s temperature due to carbon dioxide emissions from burning fossil fuels also known as greenhouse gases (Global Warming). The carbon dioxide traps heat which would make the temperature to rise, this is known as the greenhouse effect. The main causes of global warming would have to be carbon dioxide and air pollution that is going around the atmosphere, trapping the sun’s heat which causes the earth to warm up. Human activity has been a key factor to that. The burning of fossil fuels causes a lot more greenhouse gases to be trapped in the
Another way people could contribute to helping put an end to global warming is to stop or lessen the amount of carbon dioxide released into the air. Scientist believe carbon dioxide stays in the air for years. This isn’t only bad to breath, but is also very harmful to both humans and other mammals. Animals are dying from the careless mistakes of humans. For example, polar bears rely on sheets of ice to rest from swimming. Due to global warming there is very little sheets of ice strong enough for the polar bears to sit on. Polar bears will travel until they are to weak to continue and end up drowning. Whenever there may be somewhere for the polar bear to rest, he still may die from lack of food. Fish that the bears eat such as trout and salmon require cold water to survive. Global warming is causing higher temperatures and this means that the fish cannot survive. When the fish die, the polar bear die, and then who’s next? Humans don’t realize that we are not invincible. Yes, we are superior, but if the whole food chain dies off then being on top of nothing will make humans into nothing.
U.S. Conditions like Florida and other states with a high range of hot spells are perfect
Another event that would occur from global warming is the drastic rise in sea level. As the Earth warms up, the polar ice caps will start to melt. This would put immense amounts of water into the Earth’s oceans. All cities along all the coasts would be flooded from the rise in sea level. This would cause people to move inland, and with more people inland, it would cause a shortage of space in some areas. With the coastal cities under water, this would cause a great economic strain on the rest of the cities throughout the world. Global Warming would also cause extreme weather.
