One of the problems that cause the increase in the temperature is waste exhaust from factories and vehicles. As a result it is also responsible for acid rain.
Acid rain defined as particulars of acid absorbed by water in snow, rain and dew. Due to the chemical acids like sulfur dioxide,
Acid rain affects the chemical balance in the atmosphere and the soil. When it rains it affects woods, buildings even human and animals on long term. When the tree dies in many places around the world the global warming affect is there were the temperature rise and the climate gets warmer.

Solution:

New techniques are used now a day to reduce the acid rain affect by removing the sulfur from exhaust gasses in factories were it can be sold to international companies interested in manufacturing products using sulfur.
There are many regulation authorities which care about environment that look after those factories and set the rules to control the emissions of their wastes.

What is it...?

Global warming issue had been increased during the last few years. Around the world the industrial revolution had speed up the green house effect. Usually the sun heats the earth .but the heat is reflected from earth or the atmosphere layers. But after in the last decades the atmosphere layers were acting just as the green house were it acts as cover that seals the heat from being reflected from earth. It had made the earth warmer and the climate is changing around the world, the ice is melting and the areas which had cold weather became warmer. In the future these effects will develop and became more un predictable

An Inconvenient truth ....Review

The film "An inconvenient truth" is a great documentary about the Global Warming .A presentation by Mr. Al Gore who became interested in the issue that affects the world by the change in the climate conditions. In the film he managed a good way to discuss the global warming. How it started what is happening now and what is accepted in the future. I believe he was an over aggressive to the issue.
