Global Warming


Our planet which is protected by a thin layer of atmosphere that keeps temperature, water and air balanced to maintain a life the planet which is knows as a paradise and its called our earth, but something wrong is happening and whose causing this is us by our ignorance and this is causing global warming which is raising the earths temperature next to exterior of the air with oceans.


The cause for this is mainly oil, which brings fuel, and gas the problem is this had become out daily life usage. And the worse part is oil is world’s finite resource and we depend on it. The burning of oil and fossil fuels has done seven hundred billon carbon dioxide pollution in to the air which cause heat trapped in the surface of the earth which is caused global warming in coming years. The green house is the procedure in which captivation and release of infrared radiation by gases in the atmosphere warm a planets minor atmosphere and exterior. variant in solar productivity have been the reason of historical climate changes.

On the other hand the “soot” which defines that refers to polluted carbon particles resulting from the partial burning of a hydrocarbon may cool or warm the surface, depending on whether it is in the air. Atmospheric soot exactly soak up solar rays, which heats the atmosphere and cools the surface. In remote areas with high soot invention, like rural India, as much as fifty percent of surface warming cause of to green house gases may be covered by atmospheric brown clouds. The outcome of changes in solar forcing in existing decades is uncertain, but small, with some research demonstrate a minor cooling effect, The scientists has warned us that this is going to be a human challenge.


The international problem since the nine tees it has been the warmest decade in the entire year the temperatures has gone up to one degree Fahrenheit from the last century
Probably this doesn’t sound like it is but it made a lot of difference this small change in degrees had caused us extreme weather conditions rising sea level, storms, flooding of cities, massive ice breaking form the Antarctic its effecting our change in climate and he effects of rising temperature from global warming have revealed its effect on the earth. The signs are universally, from melting glaciers and sea ice in the North and South pole, the rise in sea level, shift in rain patterns deficiency and floods will become more widespread. This of this will have an affect on our ecosystem, which will cause the destruction of various animals.



This stage of this disaster and the big cooperation have done nothing about and instead they have gained money and power the richest countries are causing the most of carbon dioxide emission in the air which they are not aware and this is kind of being selfish to the other parts of the world.


All in all, we can get off oil and slow global warming and use energy more efficiently and support energy resources we should use new green technology that don’t burn carbon dioxide like wind and solar power we have to support non profit green organization things like daily life we can do are Reduce, Reuse, Recycle, utilize fewer Heat and Air habituation, make use of compact fluorescent light bulbs, drive less walk more, get Energy Efficient Products, operate Less Hot Water, Use the Off button, plant trees, And less energy use means less reliance on the fossil fuels that produce greenhouse gases and be a factor to global warming. There is a lot we can do to help stop global warming, but the hardest part is committing yourself to make the changes. It is important to know that small changes can make a big impact.

Reflection 2


by the end of the semester we had a full idea about the  course in general , we have learnt how to make a full project and how to write an assays of min 600 words.
all because  of Mr. hedley we knew what LSEC is all about and how do we deal with projects, assignments, assays in a professional way and to do it in a good way.
special thanks to Mr. hedley who began with us from the beginning of the course until the end of it and stopped on every small point which made us  improve our writing and searching skills.
Speaking of myself , I will not forget the steps of doing a project because I'm sure that we will need those skills in the future in the majors coming ahead in the next years.
It was a target for me to bring an A on the course and so it happened.
Again I would thank Mr. hedley our teacher for all what he have done.
