1. Global warming

2. GLOBAL WARMING
It is when the temperature of the earth increases globally and this happens due to affect of the green house gases on the atmosphere.
Examples of greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane )

3. For example: the usage of cars, plans, ships,…., etc.
They are produced in many ways, and we’ve become desynthesised because they are involved in our daily lives so much so, that we don’t even notice when we are producing them anymore.
For example: the usage of cars, plans, ships,…., etc.
especially the factories and oil refineries.

4. What happens globally
It may sound to us that all that is going to happen world wide is just rising up of the temperature, but it is not only that and we will also have other changes in the climate, scientist say that what is going to happen is that each state of climate will be acute in the amount of its happening
Some places might face changes in the climate.

5. What causes it
Global warming as we stated earlier is caused by the greenhouse gasses,
and this is caused due to the smoke coming out from factories, oil refineries,
cars, trucks, plans, boats,….,etc.
all of these gasses that come out mainly as smoke rise up to the upper part of the atmosphere (the Ozone)

6. And when they accumulate they cause the blocking of some of the infra-red rays that are coming from the sun and used to be reflected outside of the earth. The trapping of more of these rays means the increase in temperature world wide and that leads to all the changes in the temperature and in other words known as Global Warming.

8. How it effects us
with all the pollution and changes in the temperatures and climates some of us may find difficulties in living and adjusting to it this fast, an example of this is: the number of people that died in the 2003 heat wave in Europe exceeded 2000 people, animals also can be affected by this global climate change and here in Canada we are witnessing a part of this problem,

9. we are witnessing the extinction of the polar bears in the North pole
And in other countries it caused the migration of animals and wild life that used to attracted tourist and that caused the governments of those countries a great loss, hence the people of those places have suffered a great loss them selves,

10. In some countries it even affected the natural sties like in Tanzania the top of the famous mountain Kilimanjaro has suffered a great amount of melting and its ice is nearly finished and in a few years there will be no more Kilimanjaro ice beaks.

11. What it adds up to
The result of this impact will be devastating if we as humans don’t find a solution for this problem soon, Drastic effects will take place if pollution continues like this each day. It has been predicted that in just less than fifty years, because of the remarkable rise of CO2 levels, the temperature will increase as well

12. CO2 level is hand in hand with temperature, so if the CO2 levels increase, the temperature will increase, too, and vise versa. Also there can be a dramatic rise in sea levels in the next fifty to seventy years due to the melting ice shelves of Greenland and Antarctica. In fact, if that were to occur, sea levels will rise 20 feet.

13. This is a small graph showing us the CO2 levels and the temperature extending several years before and going up to the year 2000.

14. Here is how some places are going to turn out when the sea levels rise ………..

17. DEBATES ON GLOBAL WARMING
Safety: from this view we cover the people that believe that there is no such thing as global warming, and these people are one of the greatest things that will effect us ,because they will not stop or reduce the consumption of the materials that cause and increase this crisis,
and this will cause a bigger and sooner impact on the world.

18. Ethics : from this view we will cover issues that relate to the ethical human life, that is all humans are the same and we all deserve a chance to live, even with animals, humans agreed that they are living creatures and that they should also be given a chance to live.
When we look at the issue from this point of view we find that,

19. A lot of people are going to be casualties of the mistakes of others.
We find that certain places will get effected more than others and the people living in these areas are going to be the ones that are greatly effected, even the animals fall under this category and even more innocent than the humans, because they

20. did not do anything to ruin the environment, and most of them are hopeless and facing extinction and some are have no wear to escape like polar bares and many others.

21. How do we fix it
There are a lot of ways to help reduce the effect of Global warming, we can use hybrids instead of regular cars that run on gasoline and diesel, we can start searching for new sources of energy to rely on instead of OIL, we can reduce the amount of power we use in our homes and work places. We can also find alternate sources of power for our homes and daily lives.

22. What is needed to study global warming
The branches of sciences that are needed to get to study the issues of global warming are a lot and some of them are Earth Science, Earth Science is just basically to study the planet Earth. Earth Science branches out to Geology, Meteorology –Oceanography –Astronomy
Chemistry ,Biology ,…. etc.

23. Where to study those courses
There are several universities in Ontario especially that provide a variety of courses. There is Queen’s University that includes the Department of Geography. It branches out into many different courses, for instance, Human Geography which relates to the effects of globalization, multiculturalism. Earth System Science, this introduces the essential processes and interrelationships between the atmosphere, oceans, etc

24. There are also Geographical Perspectives on Global Change programs as well as Water Resources, and many more. Other universities include the University of Western Ontario where they provide courses such as Environmental Science, Ecosystem Health, Earth Science and the like. Also University of Toronto, York University, University of Waterloo, University of Windsor.
